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. The view is restricted to include only those entries in the database which have the MODIFIED flag set, i.e. that have been changed since the database was last viewed by the manager. This table can be used to read all the modified entries in the table. This is the table generally used to update the contents of a station map in a management station. Note that it can take a reasonable time to read the contents of the table and in that time other changes may occur. To detect this an additional MIB parameter is specified 'esDatabaseState'. This parameter is normally set to 'NO-CHANGE'. When any change is made to the database the value of this parameter becomes 'MODIFIED'. It will remain in this state until a manager sets it back to NO-CHANGE. The recommended access for this table is as follows:

do { write 'NO-CHANGE' to esDatabaseState read modified table read esDatabaseState } while esDatabaseState is MODIFIED

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.
