Usage guidelines
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.
Examples
# Configure the padding content for the remote ID sub-option as device001.
<Sysname> system-view
[Sysname] interface gigabitethernet 3/1/1
[Sysname-GigabitEthernet3/1/1] dhcp relay information remote-id string device001
