To view the configured static routes for the management port, use the show ip management-route
command in the EXEC privilege mode.

By default, FTOS drops directed broadcast packets destined for an interface. This default setting provides
some protection against Denial of Service (DOS) attacks.
To enable FTOS to receive directed broadcasts, use the following command in the INTERFACE mode:

ip directed-broadcast INTERFACE Enable directed broadcast.
To view the configuration, use the show config command in the INTERFACE mode.
For protocols such as Dynamic Host Configuration Protocol (DHCP), relay devices respond to UDP
broadcasts with information such as boot-up information. You can configure the IP address of a relay
device (or the helper address) on an interface. Add multiple DHCP servers by entering the ip
helper-address command multiple times. If multiple servers are defined, an incoming request is sent
simultaneously to all configured servers and the reply is forwarded to the DHCP client.
FTOS uses standard DHCP ports, that is UDP ports 67 (server) and 68 (client) for DHCP relay services. It
listens on port 67 and if it receives a broadcast, the software converts it to unicast, and forwards to it to the
DHCP-server with source port=68 and destination port=67.
