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

Definition
A short is detected on the cable. The location, in this Example is 92
meters. The short is accurate to plus or minus one meter.
An opening is detected on the cable. The location, in this Example is
93 meters. The open is accurate to plus or minus one meter.
There is an impedance mismatch in the cables.
