sw:admin> setGbicMode 1
When activated, only ports with GBICs installed are included in the
crossPortTest list of ports to test. For example, if only ports 0 and 3 have GBICs
installed and the GBIC mode is activated, crossPortTest limits its testing solely
to ports 0 and 3.
The state of the GBIC mode is saved in flash memory. It stays activated (even
after a restart or a power off and power on cycle) until it is disabled as follows:
sw:admin> setGbicMode 0
An example mode of operation is to disable the switch, set the GBIC mode to 1,
and execute the crossPortTest command with singlePortAlso activated. The
crossPortTest would then limit its testing to:
v
Only ports that have GBICs installed
v
All GBIC ports properly cable loopbacked
v
Ports connected to themselves (single-port connections)
The command syntax is
crossPortTest <Frames>
,
<0 or 1>
, where:
v <nFrames>
determines the number of frames to run
If you do not include the
<nFrames>
parameter, the test runs until you press Enter.
v <0 or 1>
determines if a single port looped back to itself is allowed:
0
– not allowed (default)
1
– allowed
Figure 50 on page 106 shows an example of the crossPortTest command.
