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
