Resetting a Switched Ethernet Port
To reset a switched Ethernet port, type:
interfaces switch slot port reset-port
Where:
• slot is the name of the module location
• port is the port number (or a list of ports, if aggregated in a port trunk) for the module
Section 3.17.8
Testing Switched Ethernet Port Cables
Diagnostics can be performed on switched Ethernet port cables to assess their overall quality.
The following sections describe how to test and diagnose switched Ethernet port cables:
•
Section 3.17.8.1, "Running a Cable Diagnostic Test"
•
Section 3.17.8.2, "Viewing Cable Diagnostic Statistics"
•
Section 3.17.8.3, "Clearing Cable Diagnostic Statistics"
Section 3.17.8.1
Running a Cable Diagnostic Test
To run a cable diagnostic test on a specific port, type:
IMPORTANT!
When cable diagnostics are performed on a port, any established network link on the port will be
dropped and normal network traffic will not be able to pass through either the Port Under Test (PUT) or
the Partner Port. When the cable diagnostic test is done, the original network port settings for both the
PUT and the Partner Port are restored along with any established link.
interfaces switch slot port diagnostics start-cable-test run runs calibration calibration
Where:
• slot is the name of the module location
• port is the port number (or a list of ports, if aggregated in a port trunk) for the module
• runs is the total number of times cable diagnostics should be performed on the selected port. When set to 0,
cable diagnostics will be performed continuously on the selected port.
• calibration is the value used to adjust or calibrate the estimated distance to fault. To calibrate the
determine estimated distance to fault, do the following:
1.
Connect an Ethernet cable with a known length (e.g. 50m) to the port that requires calibration. Do not
connect the other end of the cable to any link partner.
2.
Run a cable diagnostic test a few times on the port. An OPEN fault should be detected.
3.
Find the average distance to the OPEN fault recorded in the log and compare it to the known length of the
cable. The difference can be used as the calibration value.
