Version Description
9.10(0.1) Introduced on the S6010-ON and S4048T-ON.
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
conguration mode. This setting causes the multicast MAC address to be mapped to the cluster IP address for
NLB mode of operation of the switch.
Related 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), congure a static multicast MAC address, associate the multicast MAC address with
the VLAN used to switch Layer 2 multicast trac, and add output ports that will receive multicast streams on the VLAN. To delete a
congured 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 trac 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 trac 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[/subport] information.
•
For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE 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 trac is forwarded:
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then
the slot/port
/subport[/subport] information.
•
For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/
port information.
