z  When you use the dhcp server forbidden-ip command to exclude an IP address that is bound to 
a user from dynamic assignment, the address can be still assigned to the user. 
z  When you use the undo dhcp server forbidden-ip command to remove the configuration, the 
specified address/address range must be consistent with the one specified with the dhcp server 
forbidden-ip command. If you have configured to exclude an address range from dynamic 
assignment, you need to specify an address range in the undo dhcp server forbidden-ip 
command instead of specifying one IP address. 
z  Using the dhcp server forbidden-ip command repeatedly can exclude multiple IP address ranges 
from allocation.

static-bind ip-address.
