 ## Summary
 WBB is required to support gNMI Subscribe with SAMPLE or ON_CHANGE mode for various counters.
-This test if to verify that DUT supports gNMI Subscribe with sample mode, updating
-the available backplane capacity counters correctly while forwarding traffic
-
-*   Get backplace capacity before any traffic is sent
-
-*   Send some traffic and wait for the sample to be collected
-
-*   Send more traffic and wait for the sample to be collected
+This test if to verify that DUT supports gNMI Subscribe with ON_CHANGE for backplane-facing-capacity
