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.

TenGigabitEthernet then the slot/port 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 traffic is forwarded:
• For a 1-Gigabit Ethernet interface, enter the keyword
GigabitEthernet then the slot/port information.
• For a Port Channel interface, enter the keywords port-
channel
then a number. The range is from 1 to 128.
• For a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet then the slot/port information.

History
The following is a list of the FTOS version history for this command.
Version 9.3.0.0 Added support for multicast MAC address on the S4810,
S4820T, S6000, Z9000, and MXL platforms.
Usage
Information
When a multicast source and multicast receivers are in the same VLAN, you can
configure a router so that multicast traffic is switched only to the ports assigned to
a VLAN that is associated with a static multicast MAC address. However, before you
can configure a static MAC address and associate it with a VLAN used to switch
Layer 2 multicast traffic, you must first enable the router for Layer 2 multicast
switching with the ip multicast-mode l2 command.
