Static MAC entry configuration
Multi-port static MAC address configuration notes
• This feature is applicable for Layer 2 traffic.
• This feature can be used to configure unicast as well as IPv4 and IPv6 multicast MAC
addresses on one or more ports. However, when a multicast MAC address is configured, the
corresponding MAC address entry cannot be used for IGMP snooping. For IPv4 multicast
addresses (range 0100.5e00.000 to 0100.5e7f.ffff) and IPv6 multicast addresses (range
3333.0000.0000 to 3333.ffff.ffff), use IGMP/MLD snooping. Other multicast addresses can
also be configured on the ports using this feature.
• FastIron devices support a maximum of 15 multi-port static MAC addresses.
• Hosts or physical interfaces normally join multicast groups dynamically, but you can also
statically configure a host or an interface to join a multicast group.
Configuring a multi-port static MAC address
For example, to add a static entry for a server with a MAC address of 0045.5563.67ff and a priority
of 7, enter the following command.
Brocade(config)#static-mac-address 0045.5563.67ff ethernet 4/2 ethernet 4/3
ethernet 4/4 priority 7
To specify a range of ports, enter the following command.
Brocade(config)#static-mac-address 0045.5563.67ff ethernet 4/2 to 4/6 priority 7
Syntax: [no] static-mac-address <mac-addr> ethernet [<slotnum>/]<portnum> ethernet
[<slotnum>/]<portnum> ethernet [<slotnum>/]<portnum> …. [priority <num>]
or
Syntax: [no] static-mac-address <mac-addr> ethernet [<slotnum>/]<portnum> to ethernet
[<slotnum>]<portnum> [priority <num>]
The <slotnum> parameter is required on chassis devices.
The <portnum> parameter is a valid port number.
The priority <num> is optional and can be a value from 0 – 7 (0 is lowest priority and 7 is highest
priority). The default priority is 0.
NOTE
The location of the static-mac-address command in the CLI depends on whether you configure
port-based VLANs on the device. If the device does not have more than one port-based VLAN (VLAN
1, which is the default VLAN that contains all the ports), the static-mac-address command is at the
global CONFIG level of the CLI. If the device has more than one port-based VLAN, then the
static-mac-address command is not available at the global CONFIG level. In this case, the command
is available at the configuration level for each port-based VLAN.
