Setting this object to noReset(1) has no effect. The agent will return the value noReset(1) when this object is read. After receiving a request to set this variable to reset(2), the agent is allowed to delay the reset for a short period. For example, it is possible to delay the reset to allow the SNMP response to be transmitted. In any event, SNMP requires that a response be transmitted. This action does not reset the management counters defined in this document nor does it affect the portAdminStatus parameters. Included in this action is the execution of a disruptive Self-Test with the following characteristics: a) The nature of the tests is not specified. b) The test resets the repeater but without affecting management information about the repeater. c) The test does not inject packets onto any segment. d) Packets received during the test can be transferred. e) The test does not interfere with management functions.

For ports receiving traffic at a maximum rate in a 100 Mb/s repeater, this counter can roll over in less than 6 minutes.

ShortEventMaxTime is greater than 74 bit times and less than 82 bit times. ShortEventMaxTime has tolerances included to provide for circuit losses between a conformance test point at the AUI and the measurement point within the state machine. Notes: ShortEvents might indicate externally generated noise hits that will cause the repeater to transmit Runts to its other ports, or propagate a collision (which might be late) back to the transmitting DTE and damaged frames to the rest of the network. It may be desirable to select the ShortEventMaxTime towards the lower end of the allowed tolerance range to accommodate bit losses suffered through physical channel devices not budgeted for within this standard. The significance of this attribute is different in 10 Mb/s and 100 Mb/s collision domains. IEEE Std 802.3, Clause 9 repeaters perform fragment extension of short events which would be counted as runts on the interconnect ports of other repeaters. IEEE Std 802.3, Clause 27 repeaters do not perform fragment extension. A discontinuity can occur in the value when the value of object rptrMonitorPortLastChange changes.

ValidPacketMinTime is greater than or equal to 552 bit times and less than 565 bit times.

A CarrierEvent greater than or equal to 552 bit times but less than 565 bit times may be counted as a runt. ValidPacketMinTime has tolerances included to provide for circuit losses between a conformance test point at the AUI and the measurement point within the state machine.

It defines objects that 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." ::= { rptrAddrTrackRptrInfo 1 } rptrAddrSearchEntry OBJECT-TYPE SYNTAX RptrAddrSearchEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "An entry containing objects for invoking an address search on a repeater."

The agent shall limit the generation of consecutive rptrInfoHealth notifications for the same repeater so that there is at least a five-second gap between notifications of this type.

This notification is sent on completion of a repeater reset action. A repeater reset action is defined as a transition to the START state of IEEE Std 802.3, Figure 9-2, when triggered by a management command (e.g., an SNMP Set on the rptrInfoReset object). The agent shall limit the generation of consecutive rptrInfoResetEvent notifications for a single repeater so that there is at least a five-second gap between notifications of this type. When notifications are throttled, they are dropped, not queued for sending at a future time. (Note that 'generating' a notification means sending to all configured recipients.) The rptrInfoResetEvent is not sent when the agent restarts and sends an SNMP coldStart or warmStart trap. However, it is recommended that a repeater agent send the rptrInfoOperStatus object as an optional object with its coldStart and warmStart trap PDUs."
