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: Currently, the DHCP relay agent handshake function on a S5500-EI series switch can only
interoperate with a Windows 2000 DHCP server.
