Enhanced Validation of Interface Ranges
You can avoid specifying spaces between the range of interfaces, separated by commas, that you
configure by using the interface range command. For example, if you enter a list of interface ranges,
such as interface range fo 2/0-1,te 10/0,fa 0/0, this configuration is considered valid. The
comma-separated list is not required to be separated by spaces in between the ranges. You can associate
multicast MAC or hardware addresses to an interface range and VLANs by using the
mac-address-
table static multicast-mac-address vlan vlan-id output-range interface command.
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
• 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.
Syntax
