Managing <strong>the</strong> MAC Address Table<br />

<strong>Configuration</strong> Task List <strong>for</strong> MAC Addressing<br />

The following list contains MAC addressing configuration tasks, all optional:<br />

• Configuring static MAC addresses (optional) on page 199<br />

• Configuring a MAC address learning limit <strong>for</strong> an interface (optional) on page 200<br />

• Verifying MAC learning-limit settings on page 201<br />

• Recovering from MAC address learning-limit violations on page 201<br />

The primary commands <strong>for</strong> this activity are:<br />

• clear mac-address-table c e s<br />

• mac-address-table aging-time c e s<br />

• mac-address-table static c e s<br />

• mac-address-table station-move c e<br />

• mac learning-limit c e<br />

• show mac-address-table c e s<br />

• show mac learning-limit c e<br />

The complete command set <strong>for</strong> managing MAC addresses is in <strong>the</strong> “MAC Addressing” section of <strong>the</strong><br />

Layer 2 chapter in <strong>the</strong> <strong>FTOS</strong> Command Reference.<br />

The MAC Address Table is controlled by:<br />

• An aging timer: A time is applied to a dynamic address in <strong>the</strong> table. A dynamic address is learned by<br />

an interface. If no packet from or to <strong>the</strong> address arrives on <strong>the</strong> switch within <strong>the</strong> timer period, <strong>the</strong><br />

address is removed from <strong>the</strong> table.<br />

The default timer is 1800 seconds. Use <strong>the</strong> mac-address-table aging-time command to modify <strong>the</strong><br />

interval.<br />

• Manually-added and removed addresses: A MAC address that you manually add to <strong>the</strong> table is<br />

static and is <strong>the</strong>re<strong>for</strong>e not affected by <strong>the</strong> timer. See <strong>the</strong> section Configuring static MAC addresses<br />

(optional) on page 199 to manually add a MAC address.<br />
