By default, secure MAC addresses are not autosaved to the startup-config file.

The autosave feature saves learned MAC addresses by copying the running configuration to the startup configuration.
If you change the autosave interval, the next save occurs according to the old interval,
and then the new interval takes effect. To change the interval immediately, disable
autosave by entering the
no autosave command, and then configure the new autosave interval using the
autosave command.
