84
remote-id: Specifies the padding content for the user-defined circuit 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 the dhcp-snooping information remote-id string command to configure the padding content for the
user-defined remote ID sub-option.
Use the undo dhcp-snooping information remote-id string command 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 a VLAN is specified, the configured remote ID sub-option only takes effect within the VLAN; if no VLAN
is specified, the configured remote ID sub-option takes effect in all VLANs. The former case has a higher
priority. The remote ID sub-option configured for a VLAN will be padded for the packets within the VLAN.
NOTE:
If you want to specify the character string sysname (a case-sensitive 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.
