Authenticated MAC addresses are stored as dynamic entries in the switch’s

address aging time is determined by the mac-address-table aging-time
command.

This parameter applies to authenticated MAC addresses configured by the MAC
Address Authentication process described in this section, as well as to any
secure MAC addresses authenticated by 802.1X, regardless of the 802.1X
Operation Mode (Single-Host, Multi-Host, or MAC-Based authentication as
described on page 247).

The maximum number of secure MAC addresses supported for the switch
system is 1024.
