UDP Broadcast

The user datagram protocol (UDP) broadcast feature is a software-based method to forward low 

throughput (not to exceed 200 pps) IP/UDP broadcast traffic arriving on a physical or VLAN interface.

Important Points to Remember

• This feature is available only on the S4820T platform.
• Routing information protocol (RIP) is not supported with the UDP Broadcast feature.
• If you configure this feature on an interface using the ip udp-helper udp-port command, the ip 

directed-broadcast command becomes ineffective on that interface.

• The existing show interface command has been modified to display the configured broadcast 

address.
