The show interfaces terse
command
shows that the LAG is down.
Solution
Check the following:

-
Verify that all member ports are up.

Logical Interface Statistics Do Not Reflect all Traffic
Problem
Description
The traffic statistics for a logical interface do not include all of the traffic.
Solution
Traffic statistics fields for logical interfaces in show
