dhcpRelayAgentCircuitIdValue
Module: COMTROL-ES8510-MIB
OID (symbolic): COMTROL-ES8510-MIB::dhcpRelayAgentCircuitIdValue
OID (numeric): 1.3.6.1.4.1.2882.2.1.1.2.5.10.1.3
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: Circuit-ID value of the Option82 added by Relay Agent, the format can be String or Hexadecimal value.
What is dhcpRelayAgentCircuitIdValue?
This read-write value holds the actual Circuit-ID content the relay agent inserts into option 82 of DHCP requests it forwards. Setting a distinct value here lets the upstream DHCP server apply port- or switch-specific policy to relayed requests, since the relay agent's insertion is separate from the switch's own local option 82 configuration. For example, an admin might set this to a string identifying the aggregation switch and uplink port, so the central DHCP server can tell which relay point a given request passed through.
