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 platform, as noted by this symbol under each
command heading: e
• 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 this feature is configured on an interface using ip udp-helper udp-port, then the command ip
directed-broadcast becomes ineffective on that interface.
Version 8.2.1.0 Introduced on E-Series ExaScale
Version 7.7.1.0 Support added for S-Series
Version 7.6.1.0 Support added for C-Series
Version 6.1.1.0 Introduced

OK Status: Terminated
TDR test is complete, no fault is detected on the
cable, and the test is terminated
Length: 92 (+/- 1) meters, Status: Shorted
A short is detected on the cable. The location, in
this example 92 meters, of the short is accurate to
plus or minus one meter.
Length: 93 (+/- 1) meters, Status: Open
