Usage Guidelines
• Host addresses must fall within the range specified for an existing
network pool.
• When a client request is received, the switch first checks for a network
address pool matching the gateway where the request originated (i.e., if
the request was forwarded by a relay server). If there is no gateway in
the client request (i.e., the request was not forwarded by a relay server),
the switch searches for a network pool matching the interface through
which the client request was received. It then searches for a manually
configured host address that falls within the matching network pool.
• 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 3-276). 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.

Use this command to specify the client identifier of a DHCP client. Use
the
no
form to remove the client identifier.
