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.

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.
NOTE: Use this option if you want multicast functionality
in an L2 VLAN without IGMP protocols.
output

For a multicast MAC address, enter the keyword output
then one of the following interfaces for which traffic is
