DHCP Pool Configuration
Usage Guidelines
• 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. If
no manually configured host address is found, it assigns an address from
the matching network address pool. However, if no matching address
pool is found the request is ignored.
• This command is valid for DHCP network address pools only. If the
mask is not specified, the class A, B, or C natural mask is used (see
page 3-295). The DHCP server assumes that all host addresses are
available. You can exclude subsets of the address space by using the ip
dhcp excluded-address command.
