Enhanced Validation of Interface Ranges
You can avoid specifying spaces between the range of interfaces, separated by commas, that you congure 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
conguration 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 trac 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 congure this feature on an interface using the ip udp-helper udp-port command, the ip directed-broadcast
command becomes ineective on that interface.
• The existing show interface command has been modied to display the congured broadcast address.
