Configuring Agent-Circuit-Id Information

You use the relay-option-82 statement to enable insertion of option 82 information in DHCP packets. You must also specify at least the circuit-id statement to include the agent-circuit-id suboption (suboption 1) of the DHCP relay agent information option.

If you specify the circuit-id statement, the format of the agent-circuit id information for Fast Ethernet (fe) or Gigabit Ethernet (ge) interfaces is one of the following, depending on your network configuration:

  • For Fast Ethernet or Gigabit Ethernet interfaces that do not use virtual local area networks (VLANs) or stacked VLANs (S-VLANs):
    (fe | ge)-fpc/pic/port
  • For Fast Ethernet or Gigabit Ethernet interfaces that use VLANs:
    (fe | ge)-fpc/pic/port:vlan-id
  • For Fast Ethernet or Gigabit Ethernet interfaces that use S-VLANs:
    (fe | ge)-fpc/pic/port:svlan-id-vlan-id

To enable insertion of option 82 information:

  1. Specify that you want to configure option 82 support.
    [edit forwarding-options dhcp-relay]
    user@host# edit relay-option-82
  2. Specify insertion of the agent-circuit id.
    [edit forwarding-options dhcp-relay relay-option-82]
    user@host# set circuit-id
