The end station database maintains information concerning end-station address information against device port for 802.3 repeater type devices. This table provides one of three views on that database.

The view provided by this particular table is indexed firstly on address type and then on address and so can be used to read the entire contents of the database in end-station address order. Additionally one can read all addresses of a certain type from the database, e.g. all IP addresses known.

There are some points to note when reading the contents of the end station table. Firstly the repeater number reported will change if a unit is moved from one repeater within a device to another or if a unit is isolated. Secondly an address will only appear in the table once. If an address which is already present in the database is found on another port then the original record is changed and the 'modified' flag set for that entry.
