Monitoring Port Statistics
You can monitor statistics of individual ports or all ports simultaneously using the Statistics Menu. The table, “Port Statistics Counters” lists the available counters that can be monitored.
Port Statistic Counters
| Counter Type | Displayed |
|
|
|
|
|
| READABLE FRAMES | The total number of frames received on the hub port. | |
|
|
|
|
| READABLE OCTETS | The total number of octets of data received on | |
|
| the hub port. | |
|
|
| |
| FCS ERRORS | The total number of packets received by the port | |
|
| that had bad Frame Check Sequence. |
|
| ALIGN ERRORS | The total number of packets received that have bad | |
|
| FCS with a |
|
| FRM TOO LONG | The total number of packets received that were | |
|
| longer than 1518 octets (including FCS octets | |
|
| but excluding framing bits) and were otherwise | |
|
| well formed. |
|
| SHORT EVENTS | The total number of packets received that were | |
|
| less than 64 octets (including FCS octets but | |
|
| excluding framing bits) and were otherwise well | |
|
| formed. | |
|
|
|
|
| RUNTS | The total number of packets received that were less | |
|
| than 64 octets due to collisions or activity duration | |
|
| was greater than the ShortEventMaxTime event | |
|
| and less than the ValidPacketMinTime event. | |
|
|
|
|
| COLLISIONS | Total collisions. | |
|
|
|
|
| LATE EVENTS | Total events received by the port where the activity | |
|
| duration is greater than the LateEventThreshold. | |
|
|
|
|
| VERY LONG EVENTS | Total events received by the port where the activity | |
|
| duration is greater than the MAU Jabber Lockup | |
|
| Protection timer TW3. | |
|
|
|
|
| RATE MISMATCH | Total frames received by the port with no collisions | |
|
| and the activity duration greater than the | |
|
| ValidPacketMinTime event and also frequency | |
|
| (data rate) is mismatched from the local frames | |
|
| mismatch frequency. | |
