hwMstpMasterBridgeID
Module: HUAWEI-IPDSLAM-MSTP-MIB
OID (symbolic): HUAWEI-IPDSLAM-MSTP-MIB::hwMstpMasterBridgeID
OID (numeric): 1.3.6.1.4.1.2011.5.25.42.4.1.5
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: Indicates the master bridge ID of an IST in an MSTP region. It is the root Bridge Identifier of the instance 0 in the region. The format of the bridge ID is bridge priority (2B) + bridge MAC address (6B). For example, if the bridge priority is 32768, and the bridge MAC address is 00.EE.DC.F9.13.20, then the bridge ID is 80.00.00.EE.DC.F9.13.20.
What is hwMstpMasterBridgeID?
Reports the 8-byte bridge ID (2-byte priority plus 6-byte MAC address) of the root bridge for instance 0 (the CIST) in this MSTP region, e.g. 80.00.00.EE.DC.F9.13.20 for a priority of 32768. Admins read this to confirm which physical switch is acting as the region's root bridge.
Examples
