CHAPTER 4

BRIDGE MIB

The ELS10-26 supports the Bridge MIB {mib-2 17} as defined in Definitions of Managed Objects for Bridges, RFC 1286 (Decker, Langille, Rijsinghani, and McCloghrie, editors).

The MIB tree prefix for reaching the Bridge MIB-II is:

1.3.6.1.2.1.17

4.1 BASE GROUP

dot1dBase	{dot1dBridge 1}
dot1dBaseBridgeAddress	{dot1dBase 1}
Octet String Read-Only

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 dot1dStpPriority a unique BridgeIdentifier is formed which is used in the Spanning Tree Protocol.

The ELS10-26 dot1dBaseBridgeAddress is the MAC address of port 1.

dot1dBaseNumPorts	{dot1dBase 2}
Integer Read-Only

The number of ports controlled by this bridging entity.

Identical to ifNumber; however, the ELS10-26 prevents bridging from being enabled for the last (port 25), which is reserved for out-of-band management.
