associated with the port. The port learns up to the maximum addresses allowed on the
port. Both relearning and aging MAC addresses are enabled.
In order to change the Learning Mode, the Lock Interface must be set to Unlocked. Once the
mode is changed, the Lock Interface can be reinstated.
•
Max Entries — Specifies the number of MAC addresses that can be learned on the port. The
Max Entries field is enabled only if Locked is selected in the Interface Status field. In
addition, the Limited Dynamic Lock mode is selected. The possible range is 1-128. The
default is 1.
