hwMstpiDesignatedRoot

Module: HUAWEI-IPDSLAM-MSTP-MIB

OID (symbolic): HUAWEI-IPDSLAM-MSTP-MIB::hwMstpiDesignatedRoot

OID (numeric): 1.3.6.1.4.1.2011.5.25.42.4.1.20.1.5

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-only

Description: The Bridge Identifier of the Root Bridge for the port of the Spanning Tree instance identified by the MSTID. 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 hwMstpiDesignatedRoot?

Reports the root bridge ID this port believes is the spanning-tree root for its instance, in priority-plus-MAC format such as 80.00.00.EE.DC.F9.13.20. Admins compare this across ports to detect inconsistent root information during a spanning-tree topology problem.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2011.5.25.42.4.1.20.1.5
snmpwalk -v2c -c public <target> HUAWEI-IPDSLAM-MSTP-MIB::hwMstpiDesignatedRoot

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2011.5.25.42.4.1.20.1.5.1
snmpget -v2c -c public <target> HUAWEI-IPDSLAM-MSTP-MIB::hwMstpiDesignatedRoot.1
