This group of attributes provides the parameters used by the layer 3 Trunk to Trunk staging protocol.

An entry in the trkProvTable.

This attribute specifies the expected node name of the module to which this Trunk is connected. Once entered, the node name must correspond to the Mod nodeName attribute of the remote node. The Trunk end points exchange their node name through the Trunk staging protocol. The staged value is validated and the remoteValidationAction will be executed for those values not matching the value supplied for this attribute. If this attribute is an empty string, then the comparison is always successful.

This attribute specifies the action to be taken if there is a mismatch between the expectedRemoteNodeName attribute and the value received from the remote end. The remoteValidationAction determines the action when a value is supplied to the expectedRemoteNodeName attribute. If this attribute is provisioned to continue then upon an unsuccessful validation staging continues, otherwise, if disable is set then the Trunk does not continue to stage but, attempts to stage again after a one minute time out. All unsuccessful validation when the expectedRemoteNodeName has been set result in the generation of an alarm. Enumeration: 'continue': 0, 'disable': 1.

This is the maximum round trip delay value used by the Trunk staging protocol, in conjunction with measuredSpeedToIf, to determine if it has taken too long to successfully stage with a remote Trunk. The value specified must be larger than the measuredRoundTripDelay or the Trunk may not successfully stage.

This attribute specifies the Trunk protocol idle time out duration in units of seconds. If the local Trunk does not receive any packets from the link for the period specified by this attribute, the Trunk enters Are You There (AYT) mode for up to two seconds. If the Trunk does not receive any packets from the remote during the AYT mode it will restage; otherwise, it exits AYT mode and continues to provide service.

Theses attribute comprise the set of provisionable override parameters supported by both the Trunk and DpnGateway components. The attributes are used when reporting operational attributes (used for metric calculations) to the routing system.

An entry in the trkOverridesTable.

This is the overridden value of link speed (bit/s) that, if staged successfully with the remote, is reported to the routing system for metric calculations. A zero indicates that an override value has not been provided and that only the measured value will be reported to the routing system. If this value is changed on a Trunk or DpnGateway that is enabled, the LOCK and UNLOCK commands must be issued to the component to restage the override with the remote.

This is the overridden value of link delay (ms) that, if staged successfully with the remote, is reported to the routing system for metric calculations. A zero indicates that an override value has not been provided and that only the measured value will be reported to the routing system. If this value is changed on a Trunk or DpnGateway that is enabled, the LOCK and UNLOCK commands must be issued to the component to restage the override with the remote.

This is the overridden value of link delay (ms) that, if staged successfully with the remote, is reported to the routing system for metric calculations. A zero indicates that an override value has not been provided and that only the measured value will be reported to the routing system. If this value is changed on a Trunk or DpnGateway that is enabled, the LOCK and UNLOCK commands must be issued to the component to restage the override with the remote.

This group contains the three OSI State attributes and the six OSI Status attributes. The descriptions generically indicate what each attribute implies about the component.

If supported by the component, this attribute indicates the OSI Standby status of the component. The value notSet indicates that either the attribute is not supported or that none of the status conditions described below are present. Note that this is a non-standard value, used because the original specification indicated this attribute was set-valued and thus, did not provide a value to indicate that none of the other three are applicable. The value hotStandby indicates that the resource is not providing service but will be immediately able to take over the role of the resource to be backed up, without initialization activity, and containing the same information as the resource to be backed up. The value coldStandby indicates the resource is a backup for another resource but will not be immediately able to take over the role of the backed up resource and will require some initialization activity.

This is the group of operational attributes supported by the Trunk.

An entry in the trkOperTable.

This attribute is the component name of the remote end which it has supplied through the Trunk staging protocol.

This group of attributes contains the set of operational parameters measured and maintained by both the Trunk and DpnGateway components.

An entry in the trkTransportTable.

This attribute indicates the current 'transmittable' bandwidth of the underlying facility. For a Trunk with a Unack subcomponent, and a DpnGateway with a Utp subcomponent, if a serial port is used, the value is the measured transmit speed of the port; if a channelized port (E1/DS1) is used, the value is the measured transmit speed of the Channel. For a Trunk with an AtmAccess subcomponent, the value is calculated by converting the VCC transmit cell rate to an equivalent bit rate. The VCC transmit cell rate is determined based on the vccReportingBw attribute of the Trunk AtmAccess component. If vccReportingBw has a value of pcr and attribute bwElastic of AtmAccess has a value of no, the peak cell rate (PCR) of the VCC, defined in txTrafficDescParm of AtmIf Vcc Vcd, is used. If vccReportingBw has a value of pcr and attribute bwElastic of AtmAccess has a value of yes, the minimum of the PCR, defined in txTrafficDescParm of AtmIf Vcc Vcd, and the current cell rate (CCR) of the VCC is used. If vccReportingBw has a value of acr, the best measurement of the actual cell rate (ACR) of the VCC is used, which is the minimum of the PCR, the CCR and the actual shaping rate (ASR). For a DpnGateway with a FrAccess subcomponent, the value indicates the committedInformationRate of FrAccess FrMuxSetup. A value of zero is displayed when the underlying facility is disabled or the current 'transmittable' bandwidth is unknown.

This attribute indicates the measured Round Trip Delay (msec) discovered with the remote through the Trunk and DpnGateway staging protocols. The value includes emission, propagation, and queuing delays. A 512 byte data packet is used to perform the measurement. A value of zero is displayed when the link is disabled or the measured Round Trip Delay is unknown.

This is the maximum transmission unit (byte size) that is supported by the Trunk or DpnGateway component. This size includes the data and routing headers. A value of zero indicates the MTU has not yet been determined.

This attribute indicates the measured Round Trip Delay (msec) discovered with the remote through the Trunk and DpnGateway staging protocols. The value includes emission, propagation, and queuing delays. A 512 byte data packet is used to perform the measurement. A value of zero is displayed when the link is disabled or the measured Round Trip Delay is unknown.

These attributes comprise the statistics collected by the Trunk component.

An entry in the trkStatsTable.

This attribute counts the number of times that the component has entered Are You There mode. This counter wraps around to zero when the maximum value is exceeded.

This attribute counts the number of packets received from the remote module. It does not include the packets received from the interrupting queue. This counter wraps around to zero when the maximum value is exceeded.

This attribute counts the number of internal trunk protocol packets (including those through the interrupting queue) transmitted to the remote module. This counter wraps around to zero when the maximum value is exceeded.

This attribute counts the number of packets received from the remote module that have been discarded. It does not include the packets received from the interrupting queue that have been discarded. This counter wraps around to zero when the maximum value is exceeded. Two main reasons that cause this counter to increase are: (1) the remote protocol is not compatible with the local protocol stack or, (2) the packet cannot be forwarded due to a recent loss of connectivity or due to congestion.

This attribute counts the number of internal trunk protocol packets (including those on the interrupting queue) received from the remote module that have been discarded. This counter wraps around to zero when the maximum value is exceeded. The three main reasons that cause this counter to increase are: (1) the two Trunks are not synchronized, (2) the remote trunk protocol is not the same version as the local protocol, and (3) the remote trunk has restaged.

This attribute counts the number of packets received on the interrupting queue from the remote module. This counter wraps around to zero when the maximum value is exceeded.

This attribute counts the number of packets received on the interrupting queue from the remote module that have been discarded. This counter wraps around to zero when the maximum value is exceeded. Two main reasons that cause this counter to increment are: (1) the remote protocol is not compatible to the local protocol stack and, (2) the packet cannot be forwarded due to either a recent loss of connectivity or due to congestion.

This attribute counts the number of times that the staging protocol has attempted to stage with the remote module. This counter wraps around to zero when the maximum value is exceeded. The main reason that causes this counter to increment is that the local hardware is up but, the local protocol cannot stage with the remote protocol due to a faulty connection. If the value is zero, then the local hardware has never enabled successfully.

This attribute counts the number of internal trunk protocol packets (including those through the interrupting queue) that have been discarded before being transmitted to the remote module. This counter wraps around to zero when the maximum value is exceeded. The main reason that causes this counter to increment is that the trunk can not get sufficient resources to create an internal trunk protocol packet.

This attribute indicates the average trunk utilization. For a Trunk/n with an Unack subcomponent, the value is the link receive utilization. It is calculated every minute by comparing the number of octets received from the remote module against the value of the Trunk/n measuredSpeedToIf. Since the trunk application solely owns the physical link, the maximum link utilization is 100%. For a Trunk/n with an AtmAccess subcomponent, the value is the VCC(s) transmit utilization. It is calculated every 30 seconds by comparing the number of cells transmitted by AtmIf Vcc(s) against the value of the Trunk/n measuredSpeedToIf. The VCCs include the trunk VCC indicated by atmConnection of Trunk/n AtmAccess and the PORS SPO (Short Path Oriented) multiplexing VCC if applicable. The PORS SPO multiplexing VCC only applies to a Trunk/n with subcomponents Pa AtmAccess, where the mode of AtmAccess is multiplexing, and the AtmAccess is linked to a second VCC indicated by atmConnection of Pa AtmAccess. Since the trunk application shares a physical link with other applications, the VCCs utilization can exceed 100%, and the value 200% is chosen as the maximum calculated utilization.

This group of provisionable attributes provides the ability to disable or enable the generation of speed change alarms by the Trunk component. It also provides the ability to disable or enable the Dynamic Speed Reporting mechanism.

An entry in the trkSpeedReportingTable.

This attribute specifies the hold off time for reporting speed increases. When the measuredSpeedToIf reaches a level specified by the speedReportingThresholds attribute, the value specifies the duration (in units of seconds) for which the measuredSpeedToIf must maintain that level before it will be reported.

This attribute specifies the lower end of the range of normal speeds for this Trunk. If the measuredSpeedToIf drops below this value the Trunk component generates a SET alarm. When the measuredSpeedToIf reaches or exceeds the value of this attribute, the Trunk component will generate a CLEAR alarm.

This attribute specifies the upper end of the range of normal speeds for this Trunk. If the measuredSpeedToIf exceeds this value the Trunk component generates a SET alarm. When the measuredSpeedToIf returns to or falls below the value of this attribute, the Trunk component will generate a CLEAR alarm.

This attribute controls the behavior of the Dynamic Speed Reporting mechanism. If its value is empty then the mechanism is disabled and neither increases nor decreases are reported. Otherwise, the attribute may contain up to seven threshold levels which are used to control the reporting of speed increases. Speed decreases are always reported immediately. If the measuredSpeedToIf increases such that it reaches one of the threshold levels which is greater than the last reported speed, the Trunk starts the speedReportingHoldOff timer. If the speed remains above this threshold until the timer expires, the Trunk component then reports the measuredSpeedToIf; otherwise the increase is not reported.

This attribute counts the number of packets received from the remote module that have been discarded. It is a vector indexed by the emission priorities (ep0, ep1 and ep2) of the packets. The highest emission priority is ep0. These counters wrap around to zero when the maximum value is exceeded. Two main reasons that cause this counter to increment are: (1) the remote protocol is not compatible to the local protocol stack and, (2) the packet cannot be forwarded due to either a recent loss of connectivity or due to congestion. DESCRIPTION

An entry in the trkDiscBpTable.
