Port Fault Details report

To run the Port Fault Details report

The Port Fault Details report displays a breakdown of individual port error types on a selected port. This report enables you to see a breakdown of inbound and outbound faults on the port by fault type. Each fault type is represented as a percentage of the total number inbound or outbound packets for the polling sample.

Port Fault Details report details:

The report displays 2 charts showing a breakdown of faults per selected port:

• breakdown of inbound faults by fault type on the port. Each fault type is represented as a % of the total number of inbound packets for the polling sample.
  
  

  Name	Description
  Aborts	discarded frames indicate insufficient resources for their transmission.
  CRC	cyclic redundancy check (CRC) indicates accidental changes to digital data caused by noise on the network.
  Align	alignment errors indicate a duplex mismatch or a physical problem on the network, e.g. cabling, a faulty port, hub connected. Alignment errors may also occur when a cable is first connected to the port.
  Giant	giant frames exceed the maximum IEEE 802.3 frame size of 1518 bytes for non-jumbo Ethernet and have a bad Frame Check Sequence (FCS). They may indicate a device with a bad NIC.
  Unclassified	port inbound fault errors outside of the designated categories.

• breakdown of outbound faults by fault type on the port. Each fault type is represented as a % of the total number of outbound packets for the polling sample.
  
  

  Name	Description
  Aborts	discarded frames indicate insufficient resources for their transmission.
  Carrier Loss	carrier loss indicates the traffic load for the port is excessive and causes the discarding of frames.
  Excessive Collisions	an excessive collision occurs when a packet has a collision 16 times in a row. The packet is then dropped. Excessive collisions may indicate the load on the segment should be split across multiple segments, a duplex mismatch with the attached device.
  Late Collisions	a late collision indicates two devices trasmit at the same time, and neither side of the connection detects a collision. This is because the time to propagate the signal from one end of the network to another is longer than the time to put the entire packet on the network.
  SQE	a Signal Quality Error (SQE) fault confirms the detection of a collision.
  Unclassified	port outbound fault errors outside of the designated categories.

1. In the Main Menu, click Reports.
2. This will open the Reports page. Click Activity Reports.
3. This will open the Activity Reports page. Click Port Fault Details.
4. This will open the Port Fault Details Options page.
5. If you want to reuse previously saved report values, select it in the Use saved values dropdown field.
6. Specify the format of the report in the Report format field.
7. Specify the View against which the report is to be run in the Please select View(s) dropdown field. From ENA v18.0 P06 upwards, you can drag Views into this field from the Drop Box.
8. Specify the device against which the report is to be run in the Please select device(s) dropdown field.
9. Specify the port against which the report is to be run in the Please select port(s) dropdown field.
10. Specify if you want the Report Period to be a Recent period or across a Range.
11. Specify the time within the reporting period for which the report is applicable in the Prime Time fields, e.g. between 09:00 and 17:00 each day.
12. ENA v17.0 P08 upwards: Specify the time zone to which you want the reporting period to apply. By default, this is set to None, which means that the time zone of the host/consolidation server is used.
13. Click Save to save your report values, Run to run immediately, or click Cancel.
