remote-id: 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 dhcp-snooping information remote-id string to configure the padding content for the user-defined remote ID sub-option. Use undo dhcp-snooping 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 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. 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-snooping information remote-id string "Sysname" command.

remote-id
: 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
dhcp-snooping information remote-id string
to configure the padding content for the user-defined
remote ID sub-option.
Use
undo dhcp-snooping 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 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.
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-snooping information remote-id string
"Sysname" command.
