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, S3048–ON, S4048–ON, 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.
