„Ageing Timeout Configuration (seconds)

The MAC Address database contains static entries, which are never aged out, and dynamically learned entries, which are removed if they are not updated within a given time. You specify that time by entering a value for the Address Ageing Timeout. You may enter any number of seconds between 0 and 65535.

IEEE 802.1D recommends a default of 300 seconds, which is the factory default.
