port veriphy This command performs cable diagnostics to diagnose any cable faults
(short, open, etc.) and report the cable length.
SYNTAX
port veriphy [port-list]
port-list - A specific port or a range of ports. (Range: 1-28, or all)
DEFAULT SETTING
Performs diagnostics for all ports.
COMMAND USAGE
â—† If a specific port is selected, the test will take approximately 5 seconds.
If all ports are selected, it can run approximately 15 seconds. When
completed, the page refreshes automatically, and you can view the
cable diagnostics results in the cable status table. Note that VeriPHY is
only accurate for cables 7 - 140 meters long.
â—† Potential conditions which may be listed by the diagnostics include:
â–
OK : Correctly terminated pair
â–
Open : Open pair, no link partner
â–
Short : Short pair,
â–
Abnormal : Terminating Impedance is not in the reference range.
â–
Short x : Cross-pair short to pair x
â–
Cross x : Abnormal cross-pair coupling, pair x
â—† Ports will be linked down while running VeriPHY. Therefore, running
VeriPHY on a management port will cause the switch to stop responding
until testing is completed.
