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 S4810 platform.
• 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.

Definition
TDR test is complete, no fault is detected on the cable, and
the test is terminated.
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.
Pair A, Length: OK Status: Terminated
Pair B, Length: 92 (+/- 1) meters, Status: Short
Pair C, Length: 93 (+/- 1) meters, Status: Open
Pair D, Length: 0 (+/- 1) meters, Status: Impedance Mismatch
— runs the TDR test.
