This test is destructive.
The SNI runs a destructive loop around of the on- and off-board looparounds. This test returns 
the result of the on-board loop around, while Test 756 returns the result of the off-board loop 
around.
For SNI-to-SNI fiber links, this test is run on both SNI circuit pack endpoints of the fiber link.

FAIL

The data is not correctly looped around on Endpoint 1 of the fiber link. Use 
list fiber-link to display fiber link endpoints.

1. Check the lightwave transceiver.

2. Replace the lightwave transceiver. If a fiber out-of-frame condition 

exists and lightwave transceivers are used, check that the lightwave 
transceivers are of the same type (both are 9823a or both are 9823b). 
If they are not the same type, replace one of the lightwave 
transceivers.

3. Replace the SNI circuit pack.
