dhcp-snooping information remote-id string
Syntax
dhcp-snooping information [ vlan vlan-id ] remote-id string { remote-id | sysname }
undo dhcp-snooping information [ vlan vlan-id ] remote-id string
View
Layer 2 Ethernet port view, Layer 2 aggregate interface view
Default level
2: System level
Parameters
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.
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.
