Usage guidelines
With this feature enabled, the DHCP relay agent considers that a DHCP client goes offline when the ARP
entry for the client ages out. In addition, it removes the client entry and sends a DHCP-RELEASE message
to the DHCP server to release the IP address of the client.
Examples
# Enable offline detection on the DHCP relay agent.
