Version Description
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 — clear dynamic ARP entries from the ARP table.
● show arp — display 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.
NOTE: Use this option if you want multicast functionality in an L2 VLAN
without IGMP protocols.
output interface For a multicast MAC address, enter the keyword output then one of the following
interfaces for which traffic is forwarded:
● For a Port Channel interface, enter the keywords port-channel then a
number.
● For a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet then the slot/port/subport information.
● For a 25-Gigabit Ethernet interface, enter the keyword twentyFiveGigE
then the slot/port/subport information.
● For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the
slot/port/subport information.
●
For a 50-Gigabit Ethernet interface, enter the keyword fiftyGigE then the
slot/port/subport information.
● For a 100-Gigabit Ethernet interface, enter the keyword hundredGigE then
the slot/port information.
output-range
interface
For a multicast MAC address, enter the keyword output-range then one of the
following interfaces to indicate a range of ports for which traffic is forwarded:
● For a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet then the slot/port/subport information.
● For a 25-Gigabit Ethernet interface, enter the keyword twentyFiveGigE
then the slot/port/subport information.
● For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the
slot/port/subport information.
● For a 50-Gigabit Ethernet interface, enter the keyword fiftyGigE then the
slot/port/subport information.
