crossPortTest Modes
The Cross Port test behaves differently according to the activated modes.
switchEnabled or switchDisabled mode
■
ONLINE mode (switch enabled before executing the test)—In the
ONLINE mode, only ports cable loopbacked to ports in the same switch
are tested. The test ignores ports connected outside of the switch. To be
successful, the test must find at least one port (if the singlePortAlso
mode is active) or two ports (if the singlePortAlso mode is not active)
cable loopbacked to each other. If not, the test displays the following
message:
Need at least 1 port(s) connected to run this test.
OR
Need at least 2 port(s) cross-connected to run this test.
■
OFFLINE mode (switch disabled before executing the test)—In the
OFFLINE mode, all ports cable loopbacked to similar ports in the same
switch are tested. The test aborts if one or more ports are not connected.
If any pair of ports is improperly connected (improperly seated GBIC
modules or cables, bad GBIC modules or cables, improper connection
of SW to LW, and so on), the following message displays:
One or more ports is not active, please doublecheck fibres on all ports.
singlePortAlso mode
Specify the singlePortAlso mode by executing the Cross Port test with a
second argument value of one.
sw:admin> crossPortTest 0, 1
In this mode, the Cross Port test allows a port to be cable loopbacked to itself
(port M is connected to port M) in addition to the supported cross connection
(port M is connected to port N). This configuration can be used to isolate bad
ports.
GBIC mode
Activate the GBIC mode by executing the following command before
executing the Cross Port test:
sw:admin> setGbicMode 1
