RFC 1493 (BRIDGE-MIB) and draft-ietf-bridge-rstpmib-03.txt

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 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.

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 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 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

Dot1dStaticAllowedToGoTo

Not supported
