Description
Use the dhcp relay hand enable command to enable the DHCP relay handshake function. With this
feature enabled, the DHCP relay agent uses the IP address of a client and the MAC address of the
DHCP relay interface to periodically send a handshake message to the DHCP server to determine
whether or not to update the clent’s binding entry.
Use the dhcp relay hand disable command to disable the DHCP relay handshake function.
By default, the DHCP relay handshake function is enabled.
Note that:
z Among S3600 series switches, only S3600-EI series switches support the two commands.
z Currently, the DHCP relay agent handshake function on a S3600-EI series switch can only
interoperate with a Windows 2000 DHCP server.
