Usage
Information
By default this command is disabled. There might be some ARP table entries which are resolved through
ARP packets which had Ethernet MAC SA different from MAC information inside the ARP packet. This
unicast data traffic flooding occurs only for those packets which use these ARP entries.
mac-address-table static (for Multicast MAC
Address)
To configure the multicast mode of network load balancing (NLB) on the switch, you must associate a 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 in
the MAC address table.
Syntax
mac-address-table static multicast-mac-address vlan vlan-id output-range
{single-interface | interface-list | interface-range}
To remove a MAC address, use the no mac-address-table static multicast-mac-address
vlan vlan-id output-range interface command.
Parameters
multicast-mac-
address
Enter the 48-bit hexadecimal address in nn:nn:nn:nn:nn:nn format.
vlan vlan-id Enter a VLAN ID used to forward L2 multicast MAC traffic to a server cluster. Valid
VLAN IDs are from 1 to 4094.
NOTE: Use this option if you want multicast functionality in an L2 VLAN
without IGMP protocols.
output-range
interface
For a multicast MAC address, enter the keyword output-range then one of the
following interfaces for which traffic is forwarded:
● For a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet then the slot/port information.
● For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the
slot/port information.
● For a port channel interface, enter the keywords port-channel then a
number.
Defaults Not configured.
