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 E-Series and S4810 platforms.
• This feature applies only to E-Series Layer 3 physical or VLAN interfaces.
• 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.
E-Series, S4810
Syntax debug ip udp-helper
To disable debug information, use the
no debug ip udp-helper
command.
Defaults Debug disabled.
