This group defines attributes associated with direct call. It defines complete connection in terms of path and call options. This connection can be permanent (pvc) or switched (svc). It can have facilities. The total number of bytes of facilities including the facility codes, and all of the facility data from all of the four classes of facilities: CCITT_Facilities DTE_Facilities National_Facilities International_Facilities must not exceed 512 bytes.

An entry in the gvcIfDcOptionsTable.

This attribute specifies the remote Numbering Plan Indicator (Npi) used in the remoteDna. Enumeration: 'e164': 1, 'x121': 0.

This attribute specifies the Data Network Address (Dna) of the remote. This is the called (destination) DTE address (Dna) to which this direct call will be sent. Initially, the called DTE address attribute must be present, that is, there must be a valid destination address. However, it may be possible in the future to configure the direct call with a mnemonic address, in which case, this attribute will contain a zero-length Dna, and the mnemonic address will be carried as one of the facilities.

This attribute contains the user data which is appended to the call request packet that is presented to the called (destination) DTE. User data can be a 0 to 128 byte string for fast select calls; otherwise, it is 0 to 16 byte string. Fast select calls are indicated as such using the X.25 ITU-T CCITT facility for 'Reverse Charging'. The length of the user data attribute is not verified during service provisioning. If more than 16 bytes of user data is specified on a call without the fast select option, then the call is cleared with a clear cause of 'local procedure error', and a diagnostic code of 39 (as defined in ITU-T (CCITT) X.25).

This attribute specifies the default transfer priority to network for all outgoing calls using this particular Dna. It can overRide the outDefaultTransferPriority provisioned in the Dna component. The transfer priority is a preference specified by an application according to its time-sensitivity requirement. Frames with high transfer priority are served by the network before the frames with normal priority. The transfer priority in Passport determines two things in use: trunk queue (among interrupting, delay, throughput), and routing metric (between delay and throughput). The following table details each transfer priority. The default of outDefaultTransferPriority is useDnaDefTP. Enumeration: 'high': 9, 'useDnaDefTP': 255, 'normal': 0.

This attribute specifies the discard priority for outgoing call using this DLCI. The discard priority has three provisioning values: normal, high, and useDnaDefPriority. Traffic with normal priority are discarded first than the traffic with high priority. The Dna default value (provisioned by outDefaultPriority) is taken if this attribute is set to the value useDnaDefPriority. The default of discardPriority is useDnaDefPriority. Enumeration: 'high': 1, 'useDnaDefPriority': 3, 'normal': 0.

This is the i'th CCITT facility required for this direct call. Within the provisioning system, the user specifies the facility code along with the facility parameters. The facility is represented internally as a hexadecimal string following the X.25 CCITT representation for facility data. The user specifies the facility code when adding, changing or deleting a facility. The upper two bits of the facility code indicate the class of facility. From the class of the facility, one can derive the number of bytes of facility data, as follows: Class A - 1 byte of fax data Class B - 2 bytes of fax data Class C - 3 bytes of fax data Class D - variable length of fax data.

*** THIS TABLE CURRENTLY NOT IMPLEMENTED *** This group defines display of interval data collected by Vc. Data in this group is variable and may depend on time when this display command is issued.

An entry in the gvcIfLcnVcIntdTable.

This attribute displays the call reference number which is a unique number generated by the switch.The same Call Reference Number is stored in the interval data (accounting record) at both ends of the call. It can be used as one of the attributes in matching duplicate records generated at each end of the call.

This attribute displays the elapsed time representing the period of this interval data. It is elapsed time in 0.1 second increments since Vc started.

This attribute displays the number of segments received at the time command was issued. This is the segment received count maintained by accounting at each end of the Vc. This counter is updated only when the packet cannot be successfully delivered out of the sink Vc and to the sink AP Conditions in which packets may be discarded by the sink Vc include: missing packets due to subnet discards, segmentation protocol violations due to subnet discard, duplicated and out-of-ranged packets and packets that arrive while Vc is in path recovery state.

This attribute displays the number of segments sent at the time command was issued. This is the segment sent count maintained by accounting at the source Vc. Vc only counts packets that Vc thinks can be delivered successfully into the subnet. In reality, these packets may be dropped by trunking, for instance. This counter is not updated when splitting fails, when Vc is in a path recovery state, when packet forwarding fails to forward this packet and when subsequent packets have to be discarded as we want to minimize the chance of out-of-sequence and do not intentionally send out-of- sequenced packets into the subnet.

This attribute displays the start time of this interval period. If Vc spans 12 hour time or time of day change startTime reflects new time as recorded at 12 hour periods or time of day changes.

*** THIS TABLE CURRENTLY NOT IMPLEMENTED *** ... Statistics(Stats) This group defines general attributes collected by general Vc. The purpose of Vc attributes is to aid end users and verification people to understand the Vc internal behavior. This is particularly useful when the network has experienced abnormality and we want to isolate problems and pinpoint trouble spots. Attributes are collected on a per Vc basis. Until a need is identified, statistics are not collected at a processor level. Each attribute is stored in a 32 bit field and is initialized to zero when a Vc enters into the data transfer state. When a PVC is disconnected and then connected again, the attributes will be reset. Attributes cannot be reset through other methods.

An entry in the gvcIfLcnVcStatsTable.

This attribute counts the number of ack stacking timer expiries. It is used as an indicator of the acknowledgment behavior across the subnet when ack stacking is in effect. If it expires often, usually this means end users will experience longer delay. The ack stacking timer specifies how long the Vc will wait before finally sending the subnet acknowledgment. if this attribute is set to a value of 0, then the Vc will automatically return acknowledgment packets without delay. If this attribute is set to a value other than zero, then the Vc will wait for this amount of time in an attempt to piggyback the acknowledgment packet on another credit or data packet. If the Vc cannot piggyback the acknowledgment packet within this time, then the packet is returned without piggybacking.

This attribute counts the number of subnet frames discarded due to the sequence number being out of range. Two Categories apply for the General Vc 1) lost Acks (previous Range) 2) unexpected Packets (next Range) Vc internally maintains its own sequence number of packet order and sequencing. Due to packet retransmission, Vc may receive duplicate packets that have the same Vc internal sequence number. Only 1 copy is accepted by the Vc and other copies of the same packets are detected through this count. This attribute can be used to record the frequency of packet retransmission due to Vc and other part of the subnet.

This attribute counts the number of subnet packets discarded due to duplication. It is used to detect software error fault or duplication caused by retransmitting.

This attribute counts the number of frames which have retransmission time-out. If packets from Vc into the subnet are discarded by the subnet, the source Vc will not receive any acknowledgment. The retransmission timer then expires and packets will be retransmitted again. Note that the Vc idle probe may be retransmitted and is included in this count. This statistics does not show the distribution of how many times packets are retransmitted (e.g. first retransmission results in successful packet forwarding).

This attribute indicates the peak size of the retransmission queue. This attribute is used as an indicator of the acknowledgment behavior across the subnet. It records the largest body of unacknowledged packets.

This attribute indicates the peak size of the out of sequence queue. This attribute is used as an indicator of the sequencing behavior across the subnet. It records the largest body of out of sequence packets.

This attribute indicates the peak size of the sequence packet queue. This attribute is used as an indicator of the sequencing behavior across the subnet. It records the largest body of out of sequence packets, which by the receipt of an expected packet have been transformed to expected packets. The number of times this peak is reached is not recorded as it is traffic dependent.

This attribute indicates the peak size of wait acks. This attribute is used as an indicator of the acknowledgment behavior across the subnet. It records the largest collective acknowledgment.

This attribute counts the number of successful Vc recovery attempts. This attribute is used as an indicator of how many times the Vc path is broken but can be recovered. This attribute is useful to record the number of network path failures.

This attribute counts the number of window closures to subnet. A packet may have been sent into the subnet but its acknowledgment from the remote Vc has not yet been received. This is a 8 bit sequence number.This number is useful in detecting whether the Vc is sending any packet into the subnet.

This attribute counts the number of window closures from subnet. This attribute is useful in detecting whether the Vc is receiving any packet from the subnet.

This attribute displays the number of times the Vc stays within the W-R region. The W-R region is a value used to determined the timing of credit transmission. Should the current window size be beneath this value, the credits will be transmitted immediately. Otherwise, they will be transmitted later with actual data. The wrTriggers statistic is therefore used to analyze the flow control and credit mechanism.

*** THIS TABLE CURRENTLY NOT IMPLEMENTED *** This group contains the three OSI State attributes. The descriptions generically indicate what each state attribute implies about the component. Note that not all the values and state combinations described here are supported by every component which uses this group. For component-specific information and the valid state combinations, refer to NTP 241-7001-150, Passport Operations and Maintenance Guide.

An entry in the gvcIfLcnStateTable.

This attribute indicates the OSI Administrative State of the component. The value locked indicates that the component is administratively prohibited from providing services for its users. A Lock or Lock - force command has been previously issued for this component. When the value is locked, the value of usageState must be idle. The value shuttingDown indicates that the component is administratively permitted to provide service to its existing users only. A Lock command was issued against the component and it is in the process of shutting down. The value unlocked indicates that the component is administratively permitted to provide services for its users. To enter this state, issue an Unlock command to this component. Enumeration: 'locked': 0, 'shuttingDown': 2, 'unlocked': 1.

This attribute indicates the OSI Operational State of the component. The value enabled indicates that the component is available for operation. Note that if adminState is locked, it would still not be providing service. The value disabled indicates that the component is not available for operation. For example, something is wrong with the component itself, or with another component on which this one depends. If the value is disabled, the usageState must be idle. Enumeration: 'disabled': 0, 'enabled': 1.

This attribute indicates the OSI Usage State of the component. The value idle indicates that the component is not currently in use. The value active indicates that the component is in use and has spare capacity to provide for additional users. The value busy indicates that the component is in use and has no spare operating capacity for additional users at this time. Enumeration: 'active': 1, 'idle': 0, 'busy': 2.

Attributes in this group defines ClosedUserGroup options associated with interlockCode. Dnas with the same Cug (interlockCode) make calls within this group. Various combinations which permit or prevent calls in the same Cug group are defined here.

An entry in the gvcIfDnaCugCugOptionsTable.

This attribute specifies the Cug type - the Cug is either a national Cug, or an international Cug. International closed user groups are usually established between DTEs for which there is an X.75 Gateway between; whereas national closed user groups are usually established between DTEs for which there is no X.75 Gateway between. (National Cugs cannot normally traverse an X.75 Gateway). If this attribute is set to national, then the Cug is a national Cug, in which case, the dnic should be left at its default value since it is not part of a national Cug. If this attribute is set to international, then the Cug is an international Cug, in which case, the dnic should be set appropriately as part of the Cug interlockCode. Enumeration: 'international': 1, 'national': 0.

This attribute specifies the dnic (Data Network ID Code) the Cug by which packet networks are identified. This attribute is not applicable if the Cug is a national Cug, as specified by the Cug type attribute. There are usually 1 or 2 dnics assigned per country, for public networks. The U.S. is an exception where each BOC has a dnic. Also, a group of private networks can have its own dnic. dnic value is not an arbitrary number. It is assigned by international agreement and controlled by CCITT.

This attribute specifies the Cug identifier of a national or international Cug call. It is an arbitrary number and it also can be called Cug in some descriptions. Interfaces (Dnas) with this number can make calls to Dnas with the same interlockCode.

This attribute, if set to yes indicates that this Cug is the preferential Cug, in which case it will be used during the call establishment phase if the DTE has not explicitly specified a Cug index in the call request packet. If set to no, then this Cug is not the preferential Cug. Only one of the Cugs associated with a particular Dna can be the preferential Cug - only one Cug can have this attribute set to yes. Enumeration: 'yes': 1, 'no': 0.

This attribute, if set to allowed indicates that outgoing calls (from the DTE into the network) be made using this particular Cug. If set to a value of disallowed, then outgoing calls cannot be made using this Cug - such calls will be cleared by the local DCE. This attribute corresponds to the CCITT 'Outgoing Calls Barred' feature for Cugs in that outgoing calls are barred if this attribute is set to a value of disallowed. Enumeration: 'disallowed': 0, 'allowed': 1.

This attribute, if set to allowed indicates that incoming calls (from the network to the DTE) be made using this particular Cug. If set to disallowed, then incoming calls cannot be made using this Cug - such calls will be cleared by the local DCE. This attribute corresponds to the CCITT 'Incoming Calls Barred' feature for Cugs in that incoming calls are barred if this attribute is set to a value of disallowed. Enumeration: 'disallowed': 0, 'allowed': 1.

This attribute, if set to yes indicates that this Cug is a privileged Cug. In DPN, at least one side of a call setup within a Cug must have the Cug as a privileged Cug. If set to no, then the Cug is not privileged. If both the local DTE and the remote DTE subscribe to the Cug, but it is not privileged, then the call will be cleared. This attribute is typically used for a host DTE which must accept calls from many other DTEs in which case the other DTEs cannot call one another, but can call the host. In this example, the host would have the privileged Cug, and the other DTEs would belong to the same Cug, but it would not be privileged. Enumeration: 'yes': 1, 'no': 0.

An entry in the gvcIfDnaSdmDevOpTable.

This attribute indicates whether the local device specified by mac is reachable or unreachable from this SNA DLR interface. The device status is determined by the SNA DLR service by sending a TEST frame with the Poll bit set to the device periodically. If a TEST frame with the Final bit set is received from the device then the device status becomes reachable; otherwise the device status is unreachable. When the device status is reachable, connections to this device are accepted. When the device status is unreachable, existing connections to the device are cleared and new connections are cleared to hunt or redirection services. Enumeration: 'unreachable': 0, 'reachable': 1.

This group defines call options of a Dna for calls which are made out of the interface represented by Dna.

An entry in the gvcIfDnaOutgoingOptionsTable.

This attribute, if set to normal indicates that the default priority for outgoing calls (from the DTE to the network) for this particular Dna is normal priority - if the priority is not specified by the DTE. If this attribute is set to high then the default priority for outgoing calls using this particular Dna is high priority. This option can also be included in X.25 signalling, in which case it will be overruled. Enumeration: 'high': 1, 'normal': 0.

This attribute specifies the default class of routing for delay/ throughput sensitive routing for all outgoing calls (from the DTE to the network)for this particular Dna. The chosen default class of routing applies to all outgoing calls established using this Dna, and applies to the packets travelling in both directions on all outgoing calls (local to remote, and remote to local). For incoming calls, the default class of routing is chosen by the calling party (as opposed to DPN, where either end of the call can choose the default routing class). This attribute, if set to a value of throughput, indicates that the default class of routing is throughput sensitive routing. If set to a value of delay, then the default class of routing is delay sensitive routing. In the future, the class of routing sensitivity may be overridden at the calling end of the call as follows: The default class of routing sensitivity can be overridden by the DTE in the call request packet through the TDS&I (Transit Delay Selection & Indication) if the DTE supports this facility. Whether or not the DTE is permitted to signal the TDS&I facility will depend on the DTE (i.e.: TDS&I is supported in X.25 only), and will depend on whether the port is configured to permit the TDS&I facility. In Passport, the treatment of DTE facilities (for example, NUI, RPOA, and TDS&I) not fully defined yet since it is not required. At the point in time when it is required, the parameter to control whether or not the DTE is permitted to signal the TDS&I will be in a Facility Treatment component. Currently, the default is to disallow the TDS&I facility from the DTE. Enumeration: 'delay': 1, 'throughput': 0.

This attribute specifies the default class of routing for reliability routing for all outgoing calls (from the DTE to the network) this particular Dna. The chosen default class of routing applies to all outgoing calls established using this Dna, and applies to the packets travelling in both directions on all outgoing calls (local to remote, and remote to local). For incoming calls, the default class of routing is chosen by the calling party (as opposed to DPN, where either end of the call can choose the default routing class). This attribute, if set to a value of normal, indicates that the default class of routing is normal reliability routing. If set to a value of high, then the default class of routing is high reliability routing. High reliability is the standard choice for most DPN and Passport services. It usually indicates that packets are overflowed or retransmitted at various routing levels. Typically high reliability results in duplication and disordering of packets in the network when errors are detected or during link congestion. However, the Vc handles the duplication and disordering to ensure that packets are delivered to the DTE properly. For the Frame Relay service, duplication of packets is not desired, in which case, normal reliability may be chosen as the preferred class of routing. Enumeration: 'high': 0, 'normal': 1.

This attribute is an extension of the Closed User Group (CUG), as follows: This attribute, if set to a value of allowed indicates that outgoing calls (from the DTE to the network) the open (non-CUG) of the network are permitted. It also permits outgoing calls to DTEs that have Incoming Access capabilities. If set to a value of disallowed, then such calls cannot be made using this Dna - such calls will be cleared by the local DCE. This attribute corresponds to the CCITT 'Closed User Group with Outgoing Access' feature for Dnas in that outgoing access is granted if this attribute is set to a value of allowed. Enumeration: 'disallowed': 0, 'allowed': 1.

This attribute specifies the default transfer priority to network for all outgoing calls using this particular Dna. It can be overRide by the transferPriority provisioned in the DLCI Direct Call sub- component. The transfer priority is a preference specified by an application according to its time-sensitivity requirement. Frames with high transfer priority are served by the network before the frames with normal priority. The transfer priority in Passport determines two things in use: trunk queue (among interrupting, delay, throughput), and routing metric (between delay and throughput). The following table descibes the details of each transfer priority: The default of outDefaultTransferPriority is normal. Enumeration: 'high': 9, 'normal': 0.

When this attribute is set to yes in the call request, the called end will use the calling end provisioning data on transfer priority to override its own provisioning data. If it is set no, the called end will use its own provisioning data on transfer priority. The default of outTransferPriorityOverRide is yes. Enumeration: 'yes': 1, 'no': 0.

This attribute, if set to a value of allowed indicates that incoming high priority, reverse charged calls (from the network to the DTE) be made to this Dna. If set to a value of disallowed, then such calls cannot be made to this Dna - such calls will be cleared by the local DCE. This attribute, together with the incNormalPriorityReverseChargeCalls attribute corresponds to the CCITT 'Reverse Charging Acceptance' feature for Dnas in that reverse charged calls are accepted if both attributes are set to a value of allowed. This attribute is ignored if the corresponding attribute, incCalls is set to a value of disallowed. Enumeration: 'disallowed': 0, 'allowed': 1.

This attribute, if set to a value of allowed indicates that incoming normal priority, reverse charged calls (from the network to the DTE) be made to this Dna.

This attribute, together with the incHighPriorityReverseChargeCalls attribute corresponds to the CCITT 'Reverse Charging Acceptance' feature for Dnas in that reverse charged calls are accepted if both attributes are set to a value of allowed. This attribute is ignored if the corresponding attribute, incCalls is set to a value of disallowed. Enumeration: 'disallowed': 0, 'allowed': 1.

This attribute, if set to a value of allowed indicates that incoming international normal charged calls (from the network to the DTE) be made to this Dna.

This attribute, if set to a value of allowed indicates that incoming calls from the same service type (e.g.: X.25, ITI, SNA) (from the network to the DTE) be made to this Dna. If set to a value of disallowed, then such calls cannot be made to this Dna - such calls will be cleared by the local DCE. This attribute is ignored if the corresponding attribute, incCalls is set to a value of disallowed. Enumeration: 'disallowed': 0, 'allowed': 1.

This attribute is an extension of the Closed User Group (CUG), as follows: This attribute, if set to a value of allowed indicates that incoming calls (from the network to the DTE) the open (non-CUG) of the network are permitted. It also permits incoming calls from DTEs that have Outgoing Access capabilities.

This attribute specifies the type of Vc call: permanentMaster, permanentSlave, permanentSlaveWithBackup, permanentBackupSlave. If the value is set to permanentMaster, then a permanent connection will be established between 2 ends. The remote end must be defined as a permanentSlave, permanentBackupSlave or permanentSlaveWithBackup. The connection cannot be established if the remote end is defined as anything else. The end defined as permanentMaster always initiates the calls. It will attempt to call once per minute. If the value is set to permanentSlave then a permanent connection will be established between 2 ends. The remote end must be defined as a permanentMaster. The connection cannot be established if the remote end is defined as anything else. The permanentSlave end will attempt to call once per minute. If the value is set to permanentSlaveWithBackup then a permanent connection will be established between the 2 ends . The remote end must be defined as a permanentMaster. The Connection cannot be established if the remote end is defined as anything else. The permanentSlaveWithBackup end will attempt to call once per minute. If the value is set to permanentBackupSlave then a permanent connection will be established between the 2 ends only if the permanentMaster end is disconnected from the permanentSlaveWithBackup end and a backup call is established by the redirection system. If the permanentSlaveWithBackup interface becomes visible again, the permanentBackupSlave end is disconnected and the permanentSlaveWithBackup end is reconnected to the permanentMaster end. The permanentBackupSlave end does not try to establish pvc call. Enumeration: 'permanentSlave': 2, 'permanentMaster': 1, 'permanentBackupSlave': 3, 'permanentSlaveWithBackup': 4.

This attribute specifies the transfer priority to network for the outgoing calls using this particular DLCI. It overRides the defaultTransferPriority provisioned in its associated Dna component. The transfer priority is a preference specified by an application according to its delay-sensitivity requirement. Frames with high transfer priority are served by the network before the frames with normal priority. Each transfer priority contains a predetermined setting for trunk queue (interrupting, delay or throughput), and routing metric (delay or throughput). When the transfer priority is set at high, the trunk queue is set to high, the routing metric is set to delay. When the transfer priority is set at normal, the trunk queue is set to normal, the routing metric is set to throughput. The default of transferPriority is useDnaDefTP. It means using the provisioning value under defaultTransferPriority of its associated Dna for this DLCI. Enumeration: 'high': 9, 'useDnaDefTP': 255, 'normal': 0.

This attribute specifies the discard priority for outgoing call using this DLCI. The discard priority has three provisioning values: normal, high, and useDnaDefPriority. Traffic with normal priority is discarded first than the traffic with high priority. The Dna default value (provisioned by outDefaultPriority) is taken if this attribute is set to the value useDnaDefPriority. The default of discardPriority is useDnaDefPriority. Enumeration: 'high': 1, 'useDnaDefPriority': 3, 'normal': 0.

Two explicit attributes discardPriority and transferPriority are created to replace H.01 and H.30 in the group VcsDirectCallOptionsProv of this file. The migrate escape here (DcComponent::migrateFaxEscape) propagates the old provisioning data under H.01 and H.30 into discardPriority and transferPriority. The rule of the above propagation are: 0 in H.01 is equivalent to discardPriority 0; 1 in H.01 is equivalent to discardPriority 1. And 0 in H.30 is equivalent to transferPriority normal; 1 in H.30 is equivalent to transferPriority high. Please refer to discardPriority and transferPriority for more information on how to use them.

If the connection is using dprsMcsFirst data path, the string dprsMcsFirst is displayed.

This group defines display of interval data collected by Vc. Data in this group is variable and may depend on time when this display command is issued.

An entry in the gvcIfDlciVcIntdTable.

This attribute displays the call reference number which is a unique number generated by the switch.The same Call Reference Number is stored in the interval data (accounting record) at both ends of the call. It can be used as one of the attributes in matching duplicate records generated at each end of the call.

This attribute displays the elapsed time representing the period of this interval data. It is elapsed time in 0.1 second increments since Vc started.

This attribute displays the number of segments received at the time command was issued. This is the segment received count maintained by accounting at each end of the Vc. This counter is updated only when the packet cannot be successfully delivered out of the sink Vc and to the sink AP Conditions in which packets may be discarded by the sink Vc include: missing packets due to subnet discards, segmentation protocol violations due to subnet discard, duplicated and out-of-ranged packets and packets that arrive while Vc is in path recovery state.

This attribute displays the number of segments sent at the time command was issued. This is the segment sent count maintained by accounting at the source Vc. Vc only counts packets that Vc thinks can be delivered successfully into the subnet. In reality, these packets may be dropped by trunking, for instance. This counter is not updated when splitting fails, when Vc is in a path recovery state, when packet forwarding fails to forward this packet and when subsequent packets have to be discarded as we want to minimize the chance of out-of-sequence and do not intentionally send out-of- sequenced packets into the subnet.

This attribute displays the start time of this interval period. If Vc spans 12 hour time or time of day change startTime reflects new time as recorded at 12 hour periods or time of day changes.

This group defines Frame Relay attributes collected by Frame Relay Vc. The purpose of Vc attributes is to aid end users and verification people to understand the Vc internal behavior. This is particularly useful when the network has experienced abnormality and we want to isolate problems and pinpoint trouble spots. Attributes are collected on a per Vc basis. Until a need is identified, statistics are not collected at a processor level. Each attribute is stored in a 32 bit field and is initialized to zero when a Vc enters into the data transfer state. When a PVC is disconnected and then connected again, the attributes will be reset. Attributes cannot be reset through other methods. Frame Relay Vc uses a best effort data packet delivery protocol and a different packet segmentation and combination methods from the General Vc. The Frame Relay Vc uses the same call setup and control mechanism (e.g. the support of non-flow control data packets) as in a General Vc. Most General Vc statistics and internal variables are used in a Frame Relay Vc and are displayed by software developers

An entry in the gvcIfDlciVcFrdTable.

This attribute displays the number of frames from link discarded due to lack of resources. It keeps track of the number of frames from link that have to be discarded. The discard reasons include insufficient memory for splitting the frame into smaller subnet packet size.

This attribute displays the number of discarded packets that can not be forwarded into the subnet because of subnet congestion. Number of frames from link discarded due to failure in forwarding a packet from Vc into the subnet.- This attribute is increased when packet forwarding fails to forward a packet into the subnet. If a frame is split into multiple subnet packets and a partial packet has to be discarded, all subsequent partial packets that have not yet been delivered to the subnet will be discarded as well.

This attribute records the number of frames from link discarded when the Vc tries to recover from internal path failure.

This attribute displays the number of frames from subnet discarded due to out of sequence range for arriving too late.

This attribute records the number of subnet packets discarded at the sink Vc due to the Vc segmentation and combination protocol error. Usually, this occurs when the subnet discards packets and thus this statistics can be used to guest the number of subnet packets that are not delivered to the Vc. It cannot be used as an actual measure because some subnet packets may have been delivered to Vc but have to be discarded because these are partial packets to a frame in which some other partial packets have not been properly delivered to Vc

This attribute displays the number of subnet packets discarded due to duplication. Although packets are not retransmitted by the Frame Relay Vc, it is possible for the subnet to retransmit packets. When packets are out-of-sequenced and copies of the same packets arrive, then this attribute is increased.

This attribute displays the number of subnet packets discarded when data transfer is suspended in Vc recovery.

This attribute displays the number of lost frame timer expiries. When this count is excessive, the network is very congested and packets have been discarded in the subnet.

This attribute displays the number times that the out of sequence byte threshold is exceeded. When the threshold is exceeded, this condition is treated as if the loss frame timer has expired and all frames queued at the sink Vc are delivered to the AP. We need to keep this count to examine if the threshold is engineered properly. This should be used in conjunction with the peak value of out-of- sequenced queue and the number of times the loss frame timer has expired. This count should be relatively small when compared with loss frame timer expiry count.

This attribute displays the frame relay peak packet count of the out of sequence queue. This attribute records the maximum queue length of the out-of-sequenced queue. The counter can be used to deduce the message buffer requirement on a Vc.

This attribute displays the frame relay peak size of the sequence packet queue. The subnet may deliver packets out-of- sequenced. These packets are then queued in an out-of-sequenced queue, waiting for a packet with the expected sequence number to come. When that packet arrives, this attribute records the maximum number of packets that were out-of-sequenced, but now have become in-sequenced. The statistics is used to measure expected queue size due to normal subnet packet disorder (not due to subnet packet discard). Current implementation also uses this statistics to set a maximum size for the out-of-sequenced queue.

This attribute displays the Vc internal packet's send sequence number. Note that a 'packet' in this context, may be either a user data packet, or an OAM frame.

This attribute displays the number of packets which have retransmission time-outs. When this count is excessive, the network is very congested and packets have been discarded in the subnet.

This attribute displays the peak size of retransmission queue. This attribute is used as an indicator of the acknowledgment behavior across the subnet. Records the largest body of unacknowledged packets.

This attribute displays the number of successful Vc recovery attempts.

This attribute displays the number times that the out of sequence packet threshold is exceeded. When the threshold is exceeded, this condition is treated as if the loss frame timer has expired and all frames queued at the sink Vc are delivered to the AP.

An entry in the gvcIfDlciSpParmsTable.

This attribute specifies whether rate enforcement is to be used on this DLCI. Turning on rate enforcement means that the data sent from the service to the virtual circuit is subjected to rate control. Enumeration: 'on': 1, 'off': 0.

This attribute specifies the committed information rate (cir) in bits per second (bit/s). When rateEnforcement is set to on, cir is the rate at which the network agrees to transfer information under normal conditions. This rate is measured over a measurement interval (t) that is determined internally based on cir and the committed burst size (bc). An exception to this occurs when cir is provisioned to be zero, in which case the measurement interval (t) must be provisioned explicitly. This attribute is ignored when rateEnforcement is off. If rateEnforcement is on and this attribute is 0, bc must also be 0.

This attribute specifies the committed burst size (bc) in bits. bc is the amount of data that a network agrees to transfer under normal conditions over a measurement interval (t). Data marked DE=1 is not accounted for in bc. This attribute is ignored when rateEnforcement is off. If rateEnforcement is on and this attribute is 0, cir must also be 0.

This attribute specifies the excess burst size (be) in bits. be is the amount of uncommitted data that the network will attempt to deliver over measurement interval (t). Data marked DE=1 by the user or by the network is accounted for here. cir, bc, and be cannot all be 0 when rateEnforcement is on.

This attribute specifies the time interval (in milliseconds) over which rates and burst sizes are measured. When cir and bc are 0 and rateEnforcement is on, this attribute must be provisioned. When cir and bc are non-zero, the time interval is internally calculated. In that situation, this attribute is ignored, and is not representative of the time interval. This attribute is also ignored when rateEnforcement is off. If rateEnforcement is on and both cir and bc are 0, this field must be non-zero.
