You can configure MAC addresses for the switch. These addresses are static MAC addresses.
Note | You can also configure a static MAC address in interface configuration mode or VLAN configuration mode. |
SUMMARY STEPS
1. switch# configure terminal
2. switch(config-)# mac-address-table static mac_address vlan vlan-id {drop | interface {type slot/port} | port-channel number} [auto-learn]
3. (Optional) switch(config-)# no mac-address-table static mac_address vlan vlan-id
DETAILED STEPS
| Command or Action | Purpose | |
|---|---|---|
| Step 1 | switch# configure terminal | Enters configuration mode. |
| Step 2 | switch(config-)# mac-address-table static mac_address vlan vlan-id {drop | interface {type slot/port} | port-channel number} [auto-learn] | Specifies a static address to add to the MAC address table.If you enable the auto-learn option, the switch will update the entry if the same MAC address is seen on a different port. |
| Step 3 | switch(config-)# no mac-address-table static mac_address vlan vlan-id | (Optional)Deletes the static entry from the MAC address table. |
This example shows how to put a static entry in the MAC address table:
switch# configure terminal
switch(config)# mac-address-table static 12ab.47dd.ff89 vlan 3 interface ethernet 2/1
You can use the mac-address-table static command to assign a static MAC address to a virtual interface.
