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 stack/slot/port/subport information.
• For a 25-Gigabit Ethernet interface, enter the keyword twentyFiveGigE then the
stack/slot/port/subport information.
• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the stack/
slot/port[/subport] information.
• For a 50-Gigabit Ethernet interface, enter the keyword fiftyGigE then the stack/
slot/port/subport information.
• For a 100-Gigabit Ethernet interface, enter the keyword hundredGigE then the
stack/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 stack/slot/port/subport information.
• For a 25-Gigabit Ethernet interface, enter the keyword twentyFiveGigE then the
stack/slot/port/subport information.
• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the stack/
slot/port[/subport] information.
• For a 50-Gigabit Ethernet interface, enter the keyword fiftyGigE then the stack/
slot/port/subport information.
• For a 100-Gigabit Ethernet interface, enter the keyword hundredGigE then the
stack/slot/port information.
• For a Management interface, enter the keyword managementethernet followed by
slot/port numbers.
• For a Port Channel interface, enter the keywords port-channel followed by a number.
