Feature Name Feature Information

DHCP Server Import All Enhancement The DHCP Server Import All Enhancement feature is an

enhancement to the import all command. Prior to this

multiple subsystems can coexist in the DHCP address pool.

When the session is terminated or the lease is released, the

imported options are cleared.

DHCP Server Multiple Subnet The DHCP Server Multiple Subnet feature enables multiple

subnets to be configured under the same DHCP address

pool.

The following commands were introduced or modified:

network(DHCP), override default-router.

DHCP Server Option to Ignore all BOOTP

Requests

The DHCP Server Option to Ignore all BOOTP Requests

feature allows the Cisco IOS DHCP server to selectively

ignore and not reply to received Bootstrap Protocol

(BOOTP) request packets.

The following command was introduced or modified: ip

dhcp bootp ignore.
