Command Mode

Usage Guideline
To validate the DHCP Client Identifier value sent by the client. If a DHCP client
sends a DHCP Client Identifier option, the DHCP server validates the value to
ensure it matches the hardware type and client hardware address. If the values
match, the DHCP server provides service to the client. If the values do not
match, the DHCP server does not respond to the client's request.
If the command is used to set the validation to not check the DHCP Client
Identifier value sent by the client, then the DHCP server only checks the
matching of the client's hardware type and hardware address as a host ID.
Example
The following example sets the DHCP pool1 to check the validation of the client
identifier option as DHCP pool1 offers IP addresses.
switch > enable
switch# configure terminal
switch(config)# ip dhcp pool pool1
switch(config-dhcp)# accept dhcp client-identifier
switch(config-dhcp)#
