vStpInsPortDesignatedRoot

Module: ALCATEL-IND1-VLAN-STP-MIB

OID (symbolic): ALCATEL-IND1-VLAN-STP-MIB::vStpInsPortDesignatedRoot

OID (numeric): 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.2.1.6

Node type: OBJECT-TYPE

Access: read-only

Description: The unique Bridge Identifier of the Bridge recorded as the Root in the Configuration BPDUs transmitted by the Designated Bridge for the segment to which the port is attached.

What is vStpInsPortDesignatedRoot?

This read-only bridge ID shows which switch the port believes is the STP root based on BPDUs received. Network engineers verify this matches vStpInsDesignatedRoot; mismatches indicate ports seeing conflicting BPDU sources. This helps detect configuration errors or BPDU hijacking.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.2.1.6
snmpwalk -v2c -c public <target> ALCATEL-IND1-VLAN-STP-MIB::vStpInsPortDesignatedRoot

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.2.1.6.1
snmpget -v2c -c public <target> ALCATEL-IND1-VLAN-STP-MIB::vStpInsPortDesignatedRoot.1
