Show the assumed cable length connected to the specific
interface (if the port number is not defined, the command is
executed for all ports).
The interface should be enabled and operate at
100Mbps or 1000Mbps.
Maximum cable length for testing should not exceed 120m.
Example execution of commands:
Test port 24 of the first device in the stack:
console#

Given below are the possible testing results for pairs:
Test failed—physical fault
OK—pair is OK
Open—break
Short—pair contacts are shorted
Impedance-mismatch—impedance mismatch (line attenuation is too large)
Short-with-pair—pairs are shorted together
Not tested—testing is not performed
Show the last testing results:
