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 trac 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 congure this feature on an interface using the ip udp-helper udp-port command, the ip directed-broadcast
command becomes ineective on that interface.
• The existing show interface command has been modied to display the congured 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.
