Commands
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.
• The existing command show interface has been modified to display the configured broadcast
address.
The commands for UDP Broadcast are:
• debug ip udp-helper
• ip udp-broadcast-address
• ip udp-helper udp-port
• show ip udp-helper
