Port Configuration
Parameters
These parameters are displayed:
•
Port – Switch port identifier.
•
Type – Displays media type. (GE – Gigabit Ethernet, Other – SFP)
•
Link Status – Shows if the port link is up or down.
•
Test Result – The results include common cable failures, as well as the status and approximate
distance to a fault, or the approximate cable length if no fault is found.
To ensure more accurate measurement of the length to a fault, first disable power-saving
mode on the link partner before running cable diagnostics.
For link-down ports, the reported distance to a fault is accurate to within +/- 2 meters. For
link-up ports, the accuracy is +/- 10 meters.
•
Last Updated – Shows the last time this port was tested.
Interface
To test the cable attached to a port:
1. Click Interface, Port, Cable Test.
2. Click Test for any port to start the cable test.
