OID list for port events
- Repeater Monitor Port Short Events
- rptrMonitorPortShortEvents 1.3.6.1.2.1.22.2.3.1.1.8 (defined in rfc1516)
This counter is incremented by one for each CarrierEvent on this port with ActivityDuration less than ShortEventMaxTime. 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. Note: shortEvents may indicate externally generated noise hits which will cause the repeater to transmit Runts to its other ports, or propagate a collision (which may be late) back to the transmitting DTE and damaged frames to the rest of the network. Implementors may wish to consider selecting 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 approximate minimum time for rollover of this counter is 16 hours. - Repeater Monitor Port Late Events
- rptrMonitorPortLateEvents 1.3.6.1.2.1.22.2.3.1.1.11 (defined in rfc1516)
This counter is incremented by one for each CarrierEvent on this port in which the CollIn(X) variable transitions to the value SQE (Ref: 9.6.6.2, IEEE 802.3 Std) while the ActivityDuration is greater than the LateEventThreshold. Such a CarrierEvent is counted twice, as both a collision and as a lateEvent. The LateEventThreshold is greater than 480 bit times and less than 565 bit times. LateEventThreshold has tolerances included to permit an implementation to build a single threshold to serve as both the LateEventThreshold and ValidPacketMinTime threshold. The approximate minimum time for rollover of this counter is 81 hours. - Repeater Monitor Port Very Long Events
- rptrMonitorPortVeryLongEvents 1.3.6.1.2.1.22.2.3.1.1.12 (defined in rfc1516)
This counter is incremented by one for each CarrierEvent on this port whose ActivityDuration is greater than the MAU Jabber Lockup Protection timer TW3 (Ref: 9.6.1 & 9.6.5, IEEE 802.3 Std). Other counters may be incremented as appropriate. - switch Port Short Events
- switchPortShortEvents 1.3.6.1.4.1.52.259.10.3.4.2.1.1.8 (defined in elh100-mib)
The number of frames received by the port that were shorter than 82 bits. - switch Port Late Events
- switchPortLateEvents 1.3.6.1.4.1.52.259.10.3.4.2.1.1.11 (defined in elh100-mib)
The number of collisions detected on the port that occurred later than 512 bit-times into the transmission of a packet. - switch Port Very Long Events
- switchPortVeryLongEvents 1.3.6.1.4.1.52.259.10.3.4.2.1.1.12 (defined in elh100-mib)
The number of times any activity continued for more than 4 to 7.5 milliseconds.
