relayVlIndex
Module: CROUTE-MIB
OID (symbolic): CROUTE-MIB::relayVlIndex
OID (numeric): 1.3.6.1.4.1.81.31.1.6.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: A unique value for each interface. Its value ranges between 1 and the value of ifNumber. The value for each interface must remain constant at least from one re-initialization of the entity's network management system to the next re-initialization.
What is relayVlIndex?
This read-only integer uniquely identifies a VLAN interface within the BOOTP/DHCP relay table, ranging between 1 and ifNumber and remaining constant across management-system reinitializations. An admin uses this index to correlate a given VLAN's relay server configuration, such as its primary and secondary server addresses, with the correct physical or logical VLAN. For example, when auditing which VLANs have DHCP relay configured, the admin matches each relayVlIndex to its corresponding VLAN interface.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.31.1.6.1.1 snmpwalk -v2c -c public <target> CROUTE-MIB::relayVlIndex
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.81.31.1.6.1.1.1 snmpget -v2c -c public <target> CROUTE-MIB::relayVlIndex.1
