History
Version 9.3(0.0) Added support for association of an IP address with multicast 
MAC address on the S4810, S4820T, S6000, and Z9000 
platforms.
Usage 
Information
For multicast mode of NLB, to associate an IP address with a multicast MAC 
address in the switch, use address resolution protocol (ARP) by entering the arp 
ip-address multicast-mac-address command in Global configuration 
mode. This setting causes the multicast MAC address to be mapped to the cluster 
IP address for NLB mode of operation of the switch.

Commands
clear arp-cache — clears dynamic ARP entries from the ARP table.
show arp — displays the ARP table.
mac-address-table static (for Multicast MAC Address)
For multicast mode of network load balancing (NLB), configure a static multicast MAC address, associate 
the multicast MAC address with the VLAN used to switch Layer 2 multicast traffic, and add output ports 
that will receive multicast streams on the VLAN. To delete a configured static multicast MAC address from 
the MAC address table on the router, enter the no mac-address-table static multicast-mac-
address command.
Syntax
mac-address-table static multicast-mac-address multicast vlan 
vlan-id range-output {single-interface | interface-list | 
interface-range} 
To remove a MAC address, use the no mac-address-table static 
multicast-mac-address output interface vlan vlan-id command.
Parameters
multicast-mac-
address
Enter the 48-bit hexadecimal address in nn:nn:nn:nn:nn:nn 
format.
multicast Enter a vlan port to where L2 multicast MAC traffic is 
forwarded.
