Ethernet port view 

2: System level 

vlan vlan-id: Specifies a VLAN ID, in the range of 1 to 4094. 

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. 

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. 

Note that: 

z 

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; that is, 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 relay information remote-id string “Sysname” command. 

 

# Configure the padding content for the remote ID sub-option as device001.
