Troubleshooting Cables
Cable test
The virtual cable test facility diagnoses cable faults and the approximate
distance to them on Gigabit Ethernet RJ-45 ports for the following switches
running the AlliedWare operating system:
■
AT-9924T
■
x900-24XT
■
x900-24XT-N
■
x900-24XS
See
“Test Facility” on page 57
for more information or the Test Facility chapter
in the AlliedWare
®
Operating System Software Reference. Not all copper SFPs
support this feature; however, those listed in
“SFP Ports” on page 20
do
support it.
The virtual cable test facility is not supported in the AlliedWare Plus operating
system.
Cable lengths
Approximate cable lengths are reported for gigabit Ethernet RJ-45 ports on the
following switches running the AlliedWare operating system:
■
AT-9924T
■
x900-24XT
■
x900-24XT-N
■
x900-24XS
Cable length is reported after the link is established. To check the length, use
the show switch port command described in the Switching chapter in the
AlliedWare
®
Operating System Software Reference. The Cable Length parameter in
the output of this command can be one of the following values:
■
<50m
■
50–80m
■
80–110m
■
110–140m
■
>140m
■
- (either the port link is down, or the port is operating at 10 Mbps or
100 Mbps)
Cable length reporting is not supported in the AlliedWare Plus operating
system.
