Usage guidelines
This command enables the DHCP relay agent to add Option 82 to DHCP requests that do not
contain Option 82 before forwarding the requests to the DHCP server. The content of Option 82 is
determined by the
dhcp relay information circuit-id
and
dhcp relay information
remote-id
commands. If the DHCP requests contain Option 82, the relay agent handles the
requests according to the strategy configured with the
dhcp relay information strategy
command.
If this feature is disabled, the relay agent forwards requests that contain or do not contain Option 82
to the DHCP server.
Examples
# Enable Option 82 support on the relay agent.
