The following references are used throughout this MIB module: [IEEE 802.3 Std] refers to IEEE 802.3/ISO 8802-3 Information processing systems - Local area networks - Part 3: Carrier sense multiple access with collision detection (CSMA/CD) access method and physical layer specifications (1993). [IEEE 802.3 Mgt] refers to IEEE 802.3u-1995, '10 Mb/s & 100 Mb/s Management, Section 30,' Supplement to ANSI/IEEE 802.3. The following terms are used throughout this MIB module. For complete formal definitions, the IEEE 802.3 standards should be consulted wherever possible: System - A managed entity compliant with this MIB, and incorporating at least one managed 802.3 repeater. Chassis - An enclosure for one managed repeater, part of a managed repeater, or several managed repeaters. It typically contains an integral power supply and a variable number of available module slots. Repeater-unit - The portion of the repeater set that is inboard of the physical media interfaces. The physical media interfaces (MAUs, AUIs) may be physically separated from the repeater-unit, or they may be integrated into the same physical package. Trivial repeater-unit - An isolated port that can gather statistics. Group - A recommended, but optional, entity defined by the IEEE 802.3 management standard, in order to support a modular numbering scheme. The classical example allows an implementor to represent field-replaceable units as groups of ports, with the port numbering matching the modular hardware implementation. System interconnect segment - An internal segment allowing interconnection of ports belonging to different physical entities into the same logical manageable repeater. Examples of implementation might be backplane busses in modular hubs, or chaining cables in stacks of hubs. Stack - A scalable system that may include managed repeaters, in which modularity is achieved by interconnecting a number of different chassis. Module - A building block in a modular chassis. It typically maps into one 'slot'; however, the range of configurations may be very large, with several modules entering one slot, or one module covering several slots.

It defines objects which allow a network management application to instruct an agent to watch for a given MAC address and report which port it was seen on. Only one address search can be in progress on each repeater at any one time. Before starting an address search, a management application should obtain 'ownership' of the entry in rptrAddrSearchTable for the repeater that is to perform the search. This is accomplished with the rptrAddrSearchLock and rptrAddrSearchStatus as follows: try_again: get(rptrAddrSearchLock, rptrAddrSearchStatus) while (rptrAddrSearchStatus != notInUse) { /* Loop waiting for objects to be available*/ short delay get(rptrAddrSearchLock, rptrAddrSearchStatus) } /* Try to claim map objects */ lock_value = rptrAddrSearchLock if ( set(rptrAddrSearchLock = lock_value, rptrAddrSearchStatus = inUse, rptrAddrSearchOwner = 'my-IP-address) == FAILURE) /* Another manager got the lock */ goto try_again /* I have the lock */ set (rptrAddrSearchAddress = <search target>) wait for rptrAddrSearchState to change from none if (rptrAddrSearchState == single) get (rptrAddrSearchGroup, rptrAddrSearchPort) /* release the lock, making sure not to overwrite anyone else's lock */ set (rptrAddrSearchLock = lock_value+1, rptrAddrSearchStatus = notInUse, rptrAddrSearchOwner = '') A management station first retrieves the values of the appropriate instances of the rptrAddrSearchLock and rptrAddrSearchStatus objects, periodically repeating the retrieval if necessary, until the value of rptrAddrSearchStatus is 'notInUse'. The management station then tries to set the same instance of the rptrAddrSearchLock object to the value it just retrieved, the same instance of the rptrAddrSearchStatus object to 'inUse', and the corresponding instance of rptrAddrSearchOwner to a value indicating itself. If the set operation succeeds, then the management station has obtained ownership of the rptrAddrSearchEntry, and the value of rptrAddrSearchLock is incremented by the agent (as per the semantics of TestAndIncr). Failure of the set operation indicates that some other manager has obtained ownership of the rptrAddrSearchEntry. Once ownership is obtained, the management station can proceed with the search operation. Note that the agent will reset rptrAddrSearchStatus to 'notInUse' if it has been in the 'inUse' state for an abnormally long period of time, to prevent a misbehaving manager from permanently locking the entry. It is suggested that this timeout period be between one and five minutes. When the management station has completed its search operation, it should free the entry by setting the instance of the rptrAddrSearchLock object to the previous value + 1, the instance of the rptrAddrSearchStatus to 'notInUse', and the instance of rptrAddrSearchOwner to a zero length string.
