Multi-port static MAC address

Multi-port static MAC address
The multi-port static MAC address feature enables you to send traffic destined for a particular MAC
address on a set of ports of a VLAN instead of flooding the traffic on all ports of the VLAN. This
feature enables you to configure a Layer 2 static multicast MAC address. This feature is supported
on both the Brocade NetIron XMR, Brocade MLX series and Brocade NetIron CER, Brocade NetIron
CES series platforms.
FIGURE 18 Multi-port static MAC address example
Consider two Brocade NetIron XMR switches, XMR 1 and XMR 2, connected by a Layer 2 Link
Aggregation Group (LAG), with member ports 1/1 and 2/1, as shown in
Figure 18 . To send traffic to
a multicast MAC 'M' to the 3/1 ports on XMR 1 and XMR 2, you can create a static multicast MAC
‘M' on the 3/1 ports and Layer 2 LAG (primary port 1/1 of Layer 2 LAG). Traffic sent to multicast
MAC 'M' from ISP1 will be sent to ports 1/1 and 3/1 on XMR 1; and XMR 2 will send the traffic
received on port 1/1 to FW-2, connected to port 3/1, instead of flooding the traffic on all ports of
the VLAN.
Configuring multi-port static MAC address
To configure multi-port static MAC address, enter the following command at the VLAN configuration
node level of the CLI. You must configure at least one port.
Brocade# vlan 10
