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 S4810 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.
