301
Command: client-identifier <unique-identifier>
no client-identifier
Function: Specifies the unique ID of the user when binding an address manually; the
“no client-identifier” command deletes the identifier.
Parameters: <unique-identifier> is the user identifier, in dotted Hex format.
Command Mode: DHCP Address Pool Mode
Usage Guide: This command is used with “host” when binding an address manually. If
the requesting client identifier matches the specified identifier, DHCP server assigns the
IP address defined in “host” command to the client.

of 00-10-5a-60-af-12 in manual address binding.
