Disabling or Re-Enabling DHCP Option 82 (dhcp-relay information) Processing on an Interface

The dhcp-relay information enable command is supported only on ICX 8200 devices.
  1. To disable DHCP option 82, enter global configuration mode by using the configure terminal command.
    device# configure terminal
  2. Enter interface configuration mode.
    device(config)# interface ethernet 1/1/4
  3. Disable DHCP option 82 on the specified interface.
    device(config-if-e1000-1/1/4)# no dhcp-relay information
  4. Re-enable DHCP option 82 as required at the interface configuration level.
    device(config-if-e1000-1/1/4)# dhcp-relay information enable

The following example disables DHCP option 82 at the interface configuration level.

device# configure terminal
device(config)# interface ethernet 1/1/4
device(config-if-e1000-1/1/4)# no dhcp-relay information enable

The following example re-enables DHCP option 82 at the interface configuration level.

device# configure terminal
device(config)# interface ethernet 1/1/4
device(config-if-e1000-1/1/4)# dhcp-relay information enable
