This command identifies a DHCP or BOOTP client to bind to an address
specified in the host command. BOOTP clients cannot transmit a client
identifier. To bind an address to a BOOTP client, you must associate a
hardware address with the host entry.

UIDELINES
◆ 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.
