What is dhcpRelayOption82CircuitID?
This field holds the custom Circuit ID string inserted into relayed DHCP packets' Option 82 field. Admins configure this with a meaningful identifier, such as a building or closet name, to help the DHCP server apply location-based policies. For example, setting dhcpRelayOption82CircuitID to "Bldg2-Closet3" identifies relayed requests from that switch as coming from that specific location.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11863.6.39.1.1.5 snmpwalk -v2c -c public <target> TPLINK-DHCPRELAY-MIB::dhcpRelayOption82CircuitID
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.11863.6.39.1.1.5.1 snmpget -v2c -c public <target> TPLINK-DHCPRELAY-MIB::dhcpRelayOption82CircuitID.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.11863.6.39.1.1.5.1 s <value>
