View Interface view Default level 2: System level Parameters circuit-id: Padding content for the user-defined circuit ID sub-option, a case-sensitive string of 3 to 63 characters. Description Use dhcp relay information circuit-id string to configure the padding content for the user-defined circuit ID sub-option. Use undo dhcp relay information circuit-id string to restore the default. By default, the padding content for the circuit ID sub-option depends on the padding format of Option 82. After you configure the padding content for the circuit ID sub-option using this command, ASCII is adopted as the code type. Related commands: dhcp relay information format and display dhcp relay information. Examples # Configure the padding content for the circuit ID sub-option as company001. system-view [Sysname] interface vlan-interface 1 [Sysname-Vlan-interface1] dhcp relay information circuit-id string company001 dhcp relay information enable Syntax dhcp relay information enable View undo dhcp relay information enable Interface view Default level 2: System level Parameters None Description Use dhcp relay information enable to enable the relay agent to support Option 82. Use undo dhcp relay information enable to disable Option 82 support. By default, Option 82 support is disabled on the DHCP relay agent. Related commands: display dhcp relay information. 27
