NomrptrAddrSearchTable

Description This table contains one entry per repeater in the system. 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 = ) 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. This is done to prevent overwriting another station's lock.
