The 
camTest
 verifies that the SID translation required by QuickLoop and implemented 
using content addressable memories (CAM) is functioning correctly. The switch must 
be offline.
An error message would look similar to the following example:
310*"011$5310*"0#135310*R1$
&
The 
portLoopbackTes
t verifies the intended functional operation of the switch by 
sending frames from each port’s transmitter back to the same port’s receiver by way 
of an internal hardware loopback.
Pressing <Enter> while the 
portLoopbackTest
 window is selected displays a 
reminder to take the switch offline, if it is not offline. If the message is displayed, take 
the switch offline.
The 
portLoopbackTest
 is an internal test which continues to run until you press any 
button. While the test is running, all GBIC module front panel LEDs rapidly flicker 
green indicating that the test is finding no errors and is processing.
To stop the test, press any button and 
0
 is displayed.
An error message would look similar to the following example:
310*11$5310*9%/$31(35310*R1$5310*$1(%=$5310*
(//#$0$5310*(//#$0$5310*#$0$#5310*30$05310*9%/$0;#($
 &
The 
crossPortTest
 verifies the intended functional operation of the switch by sending 
frames from each port’s transmitter by way of the GBIC and external cable and back to 
another port’s receiver. It exercises the entire path of the switch.
Figure 5-1 is a recommended connection when executing the 
crossPortTest
 com-
mand. The cables need not be connected. A port can be connected to any port in the 
same switch provided the connection is of the same technology, meaning copper 
ports must connect to copper ports, SW ports to SW ports, and LW ports to LW ports.
