The RAM-resident Address Table in an HLS non-Token-Bus Bridge.

An instance of this object-type exists for each entry in the RAM-resident Address Table in a HLS non-Token-Bus Bridge. The format of the OCTET STRING is: 1st octet: 1 = Static flag set 0 = Static flag not set 2nd octet: 1 = Restrict flag set 0 = Restrict flag not set 3rd octet: 1 = Origin flag set 0 = Origin flag not set 4th octet: 0 = Bridges own address 1 = Address on Channel 0 2 = Address on Channel 1 3 = Address is global (i.e. on all Channels) Setting an instance of this object-type to a value of ASN.1 type NULL, causes the identified entry in the RAM-resident Address Table to be deleted.

The MAC address associated with this entry

Setting this value causes the re-creation of the filtered subset (see the object ramAddrTab8000FilterEntry) of the RAM-resident Address Table in a HLS 80xx Bridge. The filtered subset consists of all entries which matched the filter value at the time of the last write to this object. The format of the OCTET STRING is: 1st octet: 0 - must not have Static flag set 1 - must have Static flag set 2 - dont care whether Static flag set 2nd octet: 0 - must not have Restrict flag set 1 - must have Restrict flag set 2 - dont care whether Restrict flag set 3rd octet: 0 - must not have Origin flag set 1 - must have Origin flag set 2 - dont care whether Origin flag set 4th octet: 1 - Address must be on channel 0 (only) 2 - Address must be on channel 1 (only) 3 - Address must be global (channels 0 AND 1) 4 - Address must not be only on channel 0 5 - Address must not be only on channel 1 6 - Address must not be global 7 - Address can be on any channels

This table contains the filtered subset of the RAM-resident Address Table in a HLS 80xx Bridge. The filtered subset consists of all entries which matched the filter value at the time of the last write to the object: ramAddrTab8000Filter. Note that the contents of this table are constant between writes to ramAddrTab8000Filter.

An instance of this object-type exists for each entry in the filtered subset of entries in the RAM-resident Address Table in a HLS 80xx Bridge. The filtered subset consists of a copy of those entries in ramAddrTab8000Tab which matched the filter value at the time of the last write to the object: ramAddrTab8000Filter.

This table contains the filtered subset of the Address Table in Non-Volatile RAM in a HLS Local/Remote Bridge. The filtered subset consists of all entries which matched the filter value at the time it was last written to the object: nvramAddrTab8000Filter. Note that the contents of this table are constant between writes to nvramAddrTab8000Filter.

For the i-th entry, this object has the value i.

Setting this object to a value causes the immediate deletion of a subset of the entries in the Address Table in Non-Volatile RAM in a HLS Local/Remote Bridge. The subset of entries to be deleted is selected by using the value (to which this object is set) as a filter against which all entries are matched, with all entries matching the filter being deleted.

Setting this object to a value causes an update of the Address Table in Non-Volatile RAM in a HLS Local/Remote Bridge. This update is the combination of the deletion of all existing entries in Non-Volatile RAM table, followed by the addition of a set of new entries. The set of new entries is a subset of the current entries in the bridges RAM-resident Address Table. That subset is selected by using the value (to which this object is set) as a filter against which all entries in the RAM-resident Address Table are matched. After the update is completed, the Address Table in Non-Volatile RAM consists of exactly those entries in the RAM-resident Address Table which match with the filter value. The format of the OCTET STRING is: 1st octet: 0 - must not have Static flag set 1 - must have Static flag set 2 - dont care whether Static flag set 2nd octet: 0 - must not have Restrict flag set 1 - must have Restrict flag set 2 - dont care whether Restrict flag set 3rd octet: 0 - must not have Origin flag set 1 - must have Origin flag set 2 - dont care whether Origin flag set 4th octet: 1 - Address must be on channel 0 (only) 2 - Address must be on channel 1 (only) 3 - Address must be global (channels 0 AND 1) 4 - Address must not be only on channel 0 5 - Address must not be only on channel 1 6 - Address must not be global 7 - Address can be on any channels

The value of this object is a single octet specifying which address space segments are to be blocked/passed by the bridge (for the purpose of load-sharing between bridges). Each address space segment corresponds to one bit in the octet; the first segment corresponds to the least significant bit, the second segment with the second leastsignificant bit; etc. A bit is set to 1 if the corresponding segment is to be blocked.

The type of physical interface being used on the serial interface to the remote bridge.

The setting of this object controls the use of data compression over the serial link between two bridges. If set to removePadding(1), then any padding for LAN transmission is not transmitted over the serial link. Such padding is required on a LAN when a packet is shorter than a minimum-sized frame.

The type of CRC used on the serial link between two bridges. Setting this object does not take effect until the next reset of the bridge. When read, the object retruns the last value written to it (which is not necessarily the value of the CRC type being used).

The encoding scheme used on the serial link between two bridges. Setting this object does not take effect until the next reset of the bridge. When read, the object retruns the last value written to it (which is not necessarily the value of the link encoding being used).

The transmit level used on the bridges token bus interface. There are sixteen valid transmit levels which occur at 1.5 dBmV intervals in the range 30.5 dBmV through 53.0 dBmV. The value of this object is the number of 1.5 dBmV intervals greater than 30.5 dBmV. Use of the new transmit level after a write, occurs after the next reset.

Both the hlsPassword(1) and the hlsPfx(2) methods require that the use of an association set-up via an HLS-defined extension to the SNMP protocol. The value of snmpCommunity(3) specifies the SNMP standard use of a community-name. The value none(0) specifies that no authentication checking is done.

The table which identifies the parameters associated with the agents generation of SNMP traps.

There is one entry of this table for each destination to which the agent sends SNMP traps.

The destination IP Address to which traps enabled in this entrys switches are sent. Writing to an instance of this object-type which does not currently exist, causes a new entry in the table to be created with default settings for the trap switches, except when the table already contains entries for the maximum number of trap destinations the agent supports.

This objects value contains one octet for each type of SNMP-standard generic trap. If the agent is enabled to send a particular type of trap to this entrys destination, the corresponding octet contains a non-zero value; otherwise, if the corresponding octet has a zero value, the agent is disabled from sending that type of trap to this entrys destination. Writing to an instance of this object-type which does not currently exist is an error. The octets for specific traps are positioned in the OCTET STRING, according to their values in the generic-trap field of an SNMP trap message: octet generic-trap field 1st coldStart(0) 2nd warmStart(1) 3rd linkDown(2) etc.

This objects value contains one octet for each type of enterprise-specific trap. If the agent is enabled to send a particular type of trap to this entrys destination, the corresponding octet contains a non-zero value; otherwise, if the corresponding octet has a zero value, the agent is disabled from sending that type of trap to this entrys destination. Writing to an instance of this object-type which does not currently exist is an error. The octets for specific traps are positioned in the OCTET STRING, according to their values in the specific-trap field of an SNMP trap message: octet value of specific-trap 1st 0 2nd 1 3rd 2 etc. Note that enterprise-specific traps must be enabled by the setting of the appropriate octet of genericTrapSwitches, before the value of this object takes effect.

An integer in the range 1 <= i <= N, where N is the maximum number of trap destinations for this agent.

The MAC address used by this bridge when it must be referred to in a unique fashion. It is recommended that this be the numerically smallest MAC address of all ports that belong to this bridge. However it is only required to be unique. When concatenated with hlsDot1dStpPriority a unique BridgeIdentifier is formed which is used in the Spanning Tree Protocol.

The number of ports controlled by this bridging entity. The value can also be determined by examining the number of entries in the port- specific table in the appropriate group. Thus, this object is a candidate for removal.

The time (in hundredths of a second) since the bridging entity was last reset or initialized.

Indicates what type of bridging this bridge can perform. If a bridge is actually performing a certain type of bridging this will be indicated by entries in the port table for the given type.

A table that contains generic information about every port that is associated with this bridge. Transparent, source-route, and srt ports are included.

A list of information for each port of the bridge.

Identifies the port for which this entry contains bridge management information. The value of this object for a particular port has the same value as the ifIndex object, defined in [4,6], for the corresponding interface.

The number of frames discarded by this port due to insufficient internal buffering. It is incremented by both transparent and source route bridges.

The number of frames discarded by this port due to excessive transit delay through the bridge. It is incremented by both transparent and source route bridges.

The number of frames discarded by this port due to an excessive size. It is incremented by both transparent and source route bridges.

An indication of what version of the Spanning Tree Protocol is being run. Early DEC Spanning Tree implementations will return decprotocol(2). IEEE 802.1d implementations will return ieee8021d(3). If future versions of the IEEE Spanning Tree Protocol are released that are incompatible with the current version a new value will be defined.

In a Spanning Tree Protocol PDU, this bridge is identified by an 8 octet string composed of hlsDot1dStpPriority concatenated with hlsDot1dBaseId. One of the uses of this 8 octet string is to determine the root of the spanning tree.

The value of sysUptIme on the occurrence of last time a topology change was detected by the bridge entity.

The total number of topology changes detected by this bridge since the management entity was last reset or initialized.

The bridge identifier of the root of the spanning tree as determined by the Spanning Tree Protocol as executed by this node. This value is used as the Root Identifier parameter in all Configuration Bridge PDUs originated by this node.

The cost of the path to the root as seen from this bridge.

Identifies the port which offers the lowest cost path from this bridge to the root bridge. The value of this object indicates the port for which the ifIndex object, defined in [4,6], of the corresponding interface has the same value.

The maximum age of Spanning Tree Protocol information learned from the network on any port before it is discarded, in units of hundredths of a second. This is the actual value that this bridge is currently using.

The amount of time between the transmission of Configuration bridge PDUs by this node on any port when it is the root of the spanning tree or trying to become so, in units of hundredths of a second. This is the actual value that this bridge is currently using.

This time value is measured in units of hundredths of a second. It is used for two purposes. Firstly, it controls how fast a port changes its spanning state when moving towards the Forwarding state. In this case, the value determines how long the port stays in a particular state before moving to the next state. For example, how long a port stays in the Listening state when moving from Blocking to Learning. Secondly, when a topology change has been detected and is underway, this time value is used to age all dynamic entries in the Forwarding Database. This is the actual value that this bridge is currently using.

This time value determines the interval length during which no more than two Configuration bridge PDUs shall be transmitted by this node, in units of hundredths of a second.

A table that contains port-specific information for the Spanning Tree Protocol.

A list of information maintained by every port about the Spanning Tree Protocol state for that port.

Identifies the port for which this entry contains Spanning Tree Protocol management information. The value of this object for a particular port has the same value as the ifIndex object, defined in [4,6], for the corresponding interface.

The concatenation of hlsDot1dStpPortPriority and hlsDot1dStpPortNum make up the Port Identifier parameter in all Configuration bridge PDUs output by this port.

This object when concatentated with hlsDot1dStpPortPriority make up the Port Identifier included in all bridge PDUs generated by this bridge. The value of this object is always the same as hlsDot1dStpPortIfIndex for the same port.

The ports current state as defined by application of the Spanning Tree Protocol. This state controls what action a port takes on reception of a frame. If the bridge has detected a port that is malfunctioning it will place that port into the broken(7) state. Implementations that permit remote administratinve control of a port may permit writing of the values disabled(1) and enabled(2). When a port is writen with the value enabled(2) the implementation will take the port to the appropriate state.

The MAC address used as the destination for all Spanning Tree Protocol PDU generated out this port.

The contribution of this port to the path cost of paths towards the spanning tree root which include this port.

The value of the Bridge Identifier that should be seen in bridge PDUs received on this port.

The path cost of the Designated Port of the segment connected to this port. This value is compared to the Root Path Cost field in received bridge PDUs.

The Bridge Identifier of the bridge which this port considers to be the Designated Bridge for this ports segment.

The Port Identifier of the port on the Designated Bridge for this ports segment.

The number of Spanning Tree Protocol BPDUs received on this port.

The number of Spanning Tree Protocol BPDUs transmitted on this port.
