Configuring Static MAC Addresses

To configure a permanent, bridging static MAC address, enter mac-address-table followed by a MAC
address, slot/port, and the VLAN ID to assign to the MAC address. For example, the following assigns a
MAC address to port 10 on slot 4 associated with VLAN 255:
-> mac-address-table 00:02:DA:00:59:0C 4/10 255
Since permanent and bridging options for a static MAC are default settings, it is not necessary to enter
them as part of the command.
The following configures a filtered static MAC address that source learning will remove from the MAC
address table the next time the switch reboots:
-> mac-address-table reset 00:02:DA:00:59:0C 3/1 500 filtering
Use the no form of this command to clear MAC address entries from the table. If the MAC address status
type (permanent, reset, or learned) is not specified, then only permanent addresses are removed from the
table. The following example removes a MAC address entry with a reset status that is assigned on port 2
of slot 3 for VLAN 855 from the MAC address table:
-> no mac-address-table reset 00:00:02:CE:10:37 3/2 855
If a slot/port and VLAN ID are not specified when removing MAC address table entries, then all MACs
defined with the specified status are removed. For example, the following command removes all learned
MAC addresses from the table, regardless of their slot/port or VLAN assignments:
-> no mac-address-table learned
To verify static MAC address configuration and other table entries, use the
command. For more information about this command, see the OmniSwitch CLI Reference Guide.

Static MAC Addresses on Link Aggregate Ports

Static MAC Addresses are not assigned to physical ports that belong to a link aggregate. Instead, they are
assigned to a link aggregate ID that represents a collection of physical ports. This ID is specified at the
time the link aggregate of ports is created and when using the mac-address-table-command.
To configure a permanent, bridging static MAC address on a link aggregate ID, enter mac-address-table
followed by a MAC address, then linkagg followed by the link aggregate ID, and the VLAN ID to assign
to the MAC address. For example, the following assigns a MAC address to link aggregate ID 2 associated
with VLAN 455:
-> mac-address-table 00:95:2A:00:3E:4C linkagg 2 455
For more information about configuring a link aggregate of ports, see

Configuring MAC Address Table Aging Time

Source learning also tracks MAC address age and removes addresses from the MAC address table that
have aged beyond the aging timer value. When a device stops sending packets, source learning keeps track
of how much time has passed since the last packet was received on the device's switch port. When this
amount of time exceeds the aging time value, the MAC is aged out of the MAC address table. Source
learning always starts tracking MAC address age from the time since the last packet was received.
