Configuring multi-port static MAC address
7
Syntax: [no] static-mac-address
[
slot#n/port#m>] [priority <0-7>]
Limitations
The configuration of multi-port static MAC address has the following limitations:
•
A maximum number of 400 multi-port MAC addresses and static MAC addresses can be
configured in a system; however, the number of configured entries is limited by the number of
multicast FIDs available in the system.
•
FIDs with the same port mask are shared among multiple multi-port MAC addresses and
multi-port ARP entries to conserve the number of multicast FIDs created in the system.
•
Multi-port static MAC address cannot be configured on VLAN groups.
•
You cannot add any of the interface MAC address as multi-port static MAC address.
•
Multi-port static MAC address can be configured for either unicast or multicast addresses.
•
Unicast MAC addresses configured as multi-port static MAC addresses will not be learned
dynamically in the system or allowed to be dynamically moved to a different port.
•
If the multi-port static MAC address being added already exists in the dynamic MAC table, then
the dynamic MAC will be deleted and replaced with the configured multi-port static MAC.
•
Trunk load-balancing is not supported. The multi-port static MAC address traffic will always be
forwarded on the active primary port of the trunk port.
•
The multi-port MAC feature is supported in a pure Layer 2 forwarding vlan to forward Layer 2
traffic to multiple ports. This feature should not be configured on a vlan with a virtual
router-interface.
Error messages
Error messages are displayed in the following cases:
•
You can configure multi-port static MAC addresses only if all the ports in the port list are
members of the VLAN.
Brocade(config-vlan-100)#static-mac 0001.0001.0003 multi-port eth 2/11
Error - Multiport mac cannot be configured, Port 2/11 is not member of vlan 100
•
You must provide the complete port mask for deleting the multi-port static MAC address
configuration.
Brocade(config-vlan-100)#no static-mac 0001.0001.0002 multi-ports eth 2/19 to
2/20
Error - the port list does not match with the configured multiport mac port
list
•
On a trunk port, multi-port static MAC address configuration is allowed only on the primary port
of the trunk.
Brocade(config-vlan-100)#static-mac-address 0001.0001.0003 multi-ports ethe
2/19 to 2/20 ethe 4/3
Error - Multiport mac cannot be configured with non-primary trunk port 4/3
•
A port with multi-port static MAC address configuration cannot be a secondary member of the
trunk group.
Brocade(config-lag-LAG1)#ports eth 4/11
