dhcpOption82CircuitIdValue
Module: COMTROL-ES8510-MIB
OID (symbolic): COMTROL-ES8510-MIB::dhcpOption82CircuitIdValue
OID (numeric): 1.3.6.1.4.1.2882.2.1.1.2.5.6.1.3
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: The Circuit-ID value of this option.
What is dhcpOption82CircuitIdValue?
This read-write value holds the actual Circuit-ID content inserted into DHCP option 82 for identifying the switch port a request came in on. This value, combined with its configured format type, lets an upstream DHCP server apply port-specific policies, such as assigning particular address ranges based on which switch port originated the request. For example, an admin might set this value to something like port5-buildingA so downstream DHCP logic can distinguish requests coming from that specific port.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2882.2.1.1.2.5.6.1.3 snmpwalk -v2c -c public <target> COMTROL-ES8510-MIB::dhcpOption82CircuitIdValue
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2882.2.1.1.2.5.6.1.3.1 snmpget -v2c -c public <target> COMTROL-ES8510-MIB::dhcpOption82CircuitIdValue.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.2882.2.1.1.2.5.6.1.3.1 s <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> dhcpOption82CircuitIdValue.1
