dDhcpROption82CircuitIdUserDef
Module: DLINKSW-DHCP-RELAY-MIB
OID (symbolic): DLINKSW-DHCP-RELAY-MIB::dDhcpROption82CircuitIdUserDef
OID (numeric): 1.3.6.1.4.1.171.26.23.1.1.9
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-write
Description: This object indicates the global user defined string as the circuit ID. This object can be modified when dDhcpROption82CircuitIdType is set to 'userDefined'. When read, a zero length string is returned when dDhcpROption82CircuitIdType is not 'userDefined'.
What is dDhcpROption82CircuitIdUserDef?
Global user-defined string (up to 32 chars) used as option 82's circuit ID when dDhcpROption82CircuitIdType is set to 'userDefined'; reads back empty otherwise. Configure this when you want a custom, human-meaningful circuit identifier rather than the switch's auto-derived VLAN/port encoding.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.26.23.1.1.9 snmpwalk -v2c -c public <target> DLINKSW-DHCP-RELAY-MIB::dDhcpROption82CircuitIdUserDef
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.26.23.1.1.9.1 snmpget -v2c -c public <target> DLINKSW-DHCP-RELAY-MIB::dDhcpROption82CircuitIdUserDef.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.26.23.1.1.9.1 s <value>
