Using the Passport 8683POS Module
Table 53 describes the parameters and variables for the test led command.
test loopback
Use the test loopback command to run a loopback test on the port. You can
perform either an internal or an external loopback test on the POS module. The
default is internal loopback. The syntax is:
test loopback <ports> <int|ext>
To test for loopback:
1 To configure the port for testing, enter:
config pos <ports> test
2 To test the loopback, either internal or external, enter:
test loopback <ports> <int|ext>
Note: You must physically inspect the LEDs on the actual Passport
8683POS Module to view the results of these tests.
