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
• Routing information protocol (RIP) is not supported with the UDP broadcast feature.
• If this feature is configured on an interface using ip udp-helper udp-port, the ip
directed-broadcast
command becomes ineffective on that interface.
• The existing command show interface has been modified to display the configured broadcast
address.
The commands for UDP Broadcast are:
• debug ip udp-helper
• ip udp-broadcast-address
• ip udp-helper udp-port
• show ip udp-helper
debug ip udp-helper
Enable UDP debug and display the debug information on a console.
Syntax

To disable debug information, use the no debug ip udp-helper command.
