switch:admin> crossPortTest 0, 1
In this mode, a port can be cable loopbacked to itself (port M is connected
to port M) in addition to being cross connected (port M is connected to
port N). This mode can be used to isolate improperly functioning ports.
GBIC Mode
Activate GBIC mode by executing the following command prior to
executing
crossPortTest
:
switch:admin> setGbicMode 1
When activated, only ports with GBICs present are tested by
crossPortTest
. For example, if only port 0 and port 3 contain GBICs,
crossPortTest
limits testing to port 0 and port 3.
The state of GBIC mode is saved in flash memory and remains active (even
after reboots or power cycles) until it is disabled:
switch:admin> setGbicMode 0
