User Guidelines

Use the command to add a static MAC address with given time-to-live in any 
mode or to add a secure MAC address in a secure mode.

Each MAC address in the MAC address table is assigned two attributes: type and 
time-to-live.

The following value of time-of-live is supported:

•

permanent— a MAC address is saved until it is removed manually.

•

delete-on-reset— a MAC address is saved until the next reboot.

•

delete-on-timeout— a MAC address that may be removed by the aging 
timer.

The following types are supported:

•

static— MAC address manually added by the command with the following 
keywords specifying its time-of-live:

-

permanent

-

delete-on-reset

-

delete-on-timeout

A static MAC address may be added in any port mode.

•

secure— A MAC address added manually or learned in a secure mode. Use 
the mac address-table static command with the secure keyword to add a 
secure MAC address. The MAC address cannot be relearned.

A secure MAC address may be added only in a secure port mode.

•

dynamic— a MAC address learned by the switch in non secure mode. A 
value of its time-to-live attribute is delete-on-timeout.
