Command Mode
DHCP Pool Configuration
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 20-5). This command is valid for manual bindings only.
