Want to summarize with AI?

Provides instructions for configuring IP directed broadcast using the CLI, guiding users through command-line steps to enable, manage, and verify directed broadcast functionality.

Procedure

Enable the translation of a directed broadcast to physical broadcasts using the ip directed-broadcast command.

Note

If you enable directed broadcast on a network interface, any incoming packet that is a broadcast for that subnet is sent out to all devices on that subnet.

By default, ip directed-broadcast is disabled and all IP directed broadcasts are dropped.

Example:

device# configure-transaction
device(config)# interface ethernet 2/1
device(config-if)# ip address 10.114.114.1 255.255.255.0
device(config-if)# ip directed-broadcast
device(config-if)# end
