The BRIDGE-MIB has been augmented with draft-ietf-bridge-rstpmib-03.txt for 802.1w support.
Objects below that are defined in the latter are marked as such.
| Table/Group | Supported Variables | Comments |
|---|---|---|
| dot1dBase group scalars | dot1dBaseBridgeAddress | |
| dot1dBaseNumPorts | This object returns the number of ports in STP (Spanning Tree Protocol) domain s0, not the total number of ports on the switch. | |
| dot1dBaseType | ||
| dot1dBasePortTable |
dot1dBasePort dot1dBasePortIfIndex dot1dBasePortCircuit dot1dBasePortMtuExceededDiscards |
dot1BasePort is supported and returns the port number. dot1dBasePortIfIndex is supported. dot1dBasePortCircuit always has the value { 0 0 } since there is a one to one correspondence between a physical port and its ifIndex. dot1dBasePortMtuExceededDiscards is supported and value can be checked if packets exceeds MTU configured on particular ports. |
| dot1dStp group scalars | dot1dStpProtocolSpecification | Values for these objects will be returned for the STP domain s0 only. For other domains, see the EXTREME-STPEXTENSTIONS-MIB. |
| dot1dStpPriority | ||
| dot1dStpTimeSinceTopologyChange | ||
| dot1dStpTopChanges | ||
| dot1dStpDesignatedRoot | ||
| dot1dStpRootCost | ||
| dot1dStpRootPort | ||
| dot1dStpMaxAge | ||
| dot1dStpHelloTime | ||
| dot1dStpHoldTime | ||
| dot1dStpForwardDelay | ||
| dot1dStpBridgeMaxAge | ||
| dot1dStpBridgeHelloTime | ||
| dot1dStpBridgeForwardDelay | ||
| dot1dStpVersion | This object is not present in the original RFC1493, but is defined in the Internet draft draft-ietf-bridge-rstp-mib-03.txt. | |
| dot1dStpTxHoldCount |
This object is not present in the original RFC1493, but is defined in the Internet draft draft-ietf-bridge-rstp-mib-03.txt. This object not supported; it always returns a value of (1). Attempting to set it yields an error. |
|
| dot1dStpPathCostDefault |
This object is not present in the original RFC1493, but is defined in the Internet draft draft-ietf-bridge-rstp-mib-03.txt. For this object only 8021d1998 (1) is supported at this time, not stp802112001 (2). Attempting to set (2) yields an error. |
|
| dot1dStpExtPortTable | All objects |
This object is not present in the original RFC1493, but is defined in the Internet draft draft-ietf-bridge-rstp-mib-03.txt. The object ‘dot1dStpPortProtocolMigration‘ is not supported; it always returns a value of (2). Attempting to set it yields an error. |
| dot1dStpPortTable | All objects | |
| STP Traps | newRoot | |
| topologyChange | ||
| dot1dTpFdbTable | Supported | The object dot1dTpFdbTable displays ports and FDB (forwarding database) MAC addresses. They include both the static and dynamic FDB entries on the switch. The MIB does not provide a way to identify the VLAN (Virtual LAN) on which the entry was learned. The port numbers are assumed to be 1 to 128 on Slot 1, and 128 to 255 on Slot 2, etc. |
| dot1dTpPortTable | Supported | |
| dot1dStatic group | Supported | |
| Dot1dStaticAllowedToGoTo | Not supported |
