When activated, only ports with GBIC modules present are tested. The state of
the GBIC mode is activated until it is disabled as follows:
sw:admin> setGbicMode 0
An example mode of operation would be to disable the switch, set the GBIC
mode to 1, and execute the Cross Port test with singlePortAlso mode activated
to limit testing to:
■
Ports with GBIC modules installed
■
Ports properly cable loopbacked
■
Port connected to themselves (single port connections)
The command syntax is
crossPortTest <nFrames>, <0 or 1>
where
<nFrames>
determines the number of frames to run, and
<0 or 1>
determines if a single port connection is allowed (
0
=not allowed,
1
=allowed).
If you do not include the
<nFrames>
parameter, the test runs until you press
Enter.
spinSilk
Figure 4-10, Figure 4-11, and Figure 4-12 show the
spinSilk
command, which
verifies the intended functional operation of the switch. Each port’s transmitter
sends frames by means of the GBIC module and external cable, to another
port’s receiver at full hardware speed (1 GB/s). The entire path of the switch is
exercised. Because the processor does not compare data on each frame, the
Spin Silk test does not report the DIAG-DATA error. Other error messages
defined for the Cross Port test and the corresponding probable causes and
actions are applicable to the Spin Silk test.
The state of the GBIC mode affects the operation of the Spin Silk test. To
activate the GBIC mode, execute the following command prior to executing
the
crossPortTest
command:
switch:admin> setGbicMode 1
When activated, only ports with GBIC modules installed are included in the
Spin Silk test's list of ports to test. For example, if only ports 0 and 3 have
GBIC modules installed and the GBIC mode is activated, the Spin Silk test
limits testing to ports 0 and 3. The state of the GBIC mode is saved in flash
memory. The GBIC mode stays activated (even after reboots or power cycles)
until you disable it with the following command:
sw:admin> setGbicMode 0
