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.
