3581.0. "Purging for MIB Addr DB Port Addr Table" by NCMAIL::SCHEID () Mon Jun 03 1996 10:39

    Given the following comments from the DEC extended repeater MIB:
    
    Address Database Port Address Table 
    -----------------------------------
    
    "This table maintains a database of source addresses of readable
    frames received from all repeater ports appearing in the agent's
    port table. This information reveals the repeater port to which a
    given station is connected. 
    
    This table augments the information found in the IETF repeater MIB's
    Address Tracking Group [6]. The Address Tracking Group maps one address
    per port. A repeater port may actually connect to multiple stations
    (e.g. a port associared with a 10BASE2 MAU). The Address Database Port 
    Address Table can map multiple addresses to a single port.
    
    The number of entries in this table is dynamic depending upon the
    number of distinct source addresses learned by the repeater.
    
    It is recommended that the agent automatically delete from this table 
    entries for addresses which have not been seen bythe repeater for some
    reasonable amount of time. The method and timeliness in which this is
    accomplished is implementation dependent". 
    
    
    
    
    What is the method and timeliness for removing the entries from the
    table.

    Without getting into a line by line description of the
    code...Approximately every 2 minutes a task is scheduled which inspects
    every entry in the address database and removes all addresses which
    have not been seen in the last 2 to 4 minutes.
