DHCP Server
– 989 –
◆ When searching for a manual binding, the switch compares the client
identifier for DHCP clients, and then compares the hardware address for
DHCP or BOOTP clients.
◆ If no manual binding has been specified for a host entry with the client-
identifier or hardware-address commands, then the switch will assign
an address from the matching network pool.
◆ If the mask is unspecified, DHCP examines its address pools. If no
mask is found in the pool database, the Class A, B, or C natural mask is
used (see page 991). This command is valid for manual bindings only.
◆ The no host command only clears the address from the DHCP server
database. It does not cancel the IP address currently in use by the
host.

Console(config-dhcp)#host 10.1.0.21 255.255.255.0
