UDP Broadcast Commands
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, S4820T, S3048ON, S4048ON, Z9000 platforms.
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.
debug ip udp-helper
Enable UDP debug and display the debug information on a console.
Syntax
debug ip udp-helper
To disable debug information, use the no debug ip udp-helper command.
Defaults Debug disabled.
