Parameters remote-id: Padding content for the user-defined remote ID sub-option, a case-sensitive string of 1 to 63 characters. sysname: Specifies the device name as the padding content for the remote ID sub-option. Description Use dhcp relay information remote-id string to configure the padding content for the user-defined remote ID sub-option. Use undo dhcp relay information remote-id string to restore the default. By default, the padding content for the remote ID sub-option depends on the padding format of Option 82. After you configure the padding content for the remote ID sub-option using this command, ASCII is adopted as the code type. If you want to specify the character string sysname (a case-insensitive character string) as the padding content for the remote ID sub-option, you need to use quotation marks to make it take effect. For example, if you want to specify Sysname as the padding content for the remote ID sub-option, you need to enter the dhcp relay information remote-id string "Sysname" command. Related commands: dhcp relay information format and display dhcp relay information. Examples # Configure the padding content for the remote ID sub-option as device001. system-view [Sysname] interface vlan-interface 1 [Sysname-Vlan-interface1] dhcp relay information remote-id string device001 dhcp relay information strategy Syntax dhcp relay information strategy { drop | keep | replace } View undo dhcp relay information strategy Interface view Default level 2: System level Parameters drop: Specifies the dropping of messages containing Option 82. keep: Specifies the forwarding of messages containing Option 82 without any change. replace: Specifies the forwarding of messages containing Option 82 after replacing the original Option 82 with the Option 82 padded in the specified padding format. Description Use dhcp relay information strategy to configure DHCP relay agent handling strategy for messages containing Option 82. Use undo dhcp relay information strategy to restore the default handling strategy. 30
