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 3-295). This command is valid for manual bindings only.
