The set protocols dhcp snooping option82 remote-id command configures the format of sub-option remote ID inserted into the DHCP Option 82 field for DHCP snooping.

NOTE: The sub-option remote ID is applied to VLANs where option82-policy is set to “insert” or “replace”.

Command Syntax

set protocols dhcp snooping option82 remote-id <system-mac | hostname>

Parameters

Parameter

Description

remote-id <system-mac | hostname>

Specifies the type of remote ID in the Option 82 field. The value could be system-mac or hostname.

By default, the sub-option remote ID is not configured which means remote ID is not enabled.

Usage Guidelines

If configured, the remote ID is unique per switch.

When “system-mac” is selected, the format of the remote ID is “system MAC”.
When “hostname” is selected, the format of the remote ID is “hostname”. The value of “hostname” can be set by the following command:

set system hostname <hostname>

Note that, when configuring Option 82 in MLAG environment, remote ID should be set to “system-mac” and circuit ID should be set to “port-index”.

Example

Configure the type of sub-option remote ID inserted into the DHCP Option 82 field.
