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.
