Note: You must physically inspect the LEDs on the actual Passport 8683POS Module to view the results of these tests.

Table 53 describes the parameters and variables for the test led command.

Table 53 test led command parameters and variables

Parameters and variables	Description

tx	Tests the LED for transmitting data on each port.

rx	Tests the LED for receiving data on each port.

off	Tests whether the LEDs go off correctly.

yellow	Tests whether the LEDs can light yellow.

green	Tests whether the LEDs can light green.

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> <intext>

Note: The loopback tests test only the control path; they do not test the data path.

To test for loopback:

1To configure the port for testing, enter: config pos <ports> test

2To test the loopback, either internal or external, enter: test loopback <ports> <intext>
