•Permanent entries are addresses that you add to the Static Database (via the Filtering Database window) that are stored in the selected module’s
•Static entries are addresses that you add to the Static Database (via the Filtering Database window). These entries remain in the selected module’s memory until it is shut down.
•Dynamic entries are addresses that you add to the Static Database (via the Filtering Database window). With the Ageing Time feature, you set the time period that these addresses are saved in the Source Address Table. Addresses that have not transmitted a packet during one complete cycle of the ageing timer are deleted from the database.
•Learned entries are addresses that are added to the Learned Database through the bridge’s learning process. With the Ageing Time feature, you set the time period that these addresses are saved in the Source Address Table. Addresses which are inactive within a cycle of the ageing timer are dropped from the database.
Learned address entries are divided into two types, Learned and Self. Address entries classified as Learned have transmitted frames destined for a device attached to a segment connected to the selected module. Address entries classified as Self are those that have sent a frame with a destination address of one of the selected module’s bridging port.
