vlBridgeGroupIndex
Module: CROUTE-MIB
OID (symbolic): CROUTE-MIB::vlBridgeGroupIndex
OID (numeric): 1.3.6.1.4.1.81.31.3.2.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: A logical number, corresponded this group of VLANs
What is vlBridgeGroupIndex?
This read-only integer reports the logical number corresponding to a group of VLANs that are bridged together. An admin uses this to identify which bridge group a particular VLAN belongs to when multiple VLANs are being bridged as one logical domain. For example, when troubleshooting why traffic from two VLANs is mixing together, the admin would check whether they share the same vlBridgeGroupIndex, confirming they're intentionally grouped.
Examples

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.31.3.2.1.2 snmpwalk -v2c -c public <target> CROUTE-MIB::vlBridgeGroupIndex
Get a specific instance (index 1):
