Switch > Port Management > Cable Diagnostics
This page lets you run cable diagnostic tests per port.
The SESPM1040-541-LT-xx Cable Diagnostics uses TDR (Time Domain Reflectometry) for remote identification of
potential cable malfunctions. Cable Diagnostics detects and reports potential cabling issues such as pair swaps,
pair polarity, and excessive skew. It can also detect cable opens, shorts, or impedance mismatch in the cable and
report accurately within one meter the distance to the fault.
The webpage allows running the cable diagnostic tests all ports that are selected. Note that Link can be lost
during the test.
