Known Affected Releases

16.7.1

Description (partial)

Symptom:
After LC double failure, no DSG tunnel traffic existed.
Falling back to primary LC didn't resolve the issue.
Remove and re-add DSG configuration in the MD resolve the issue.


After making DSG Classifier changes (typically an addition), DSG tunnels will function as expected. However, upon LCHA failover, the new DSG classifier/tunnel will be missing.

This often translates into 1) Large DSG changes made months prior and 2) When upgrading via LCHA failover for hitless upgrades, we see DSG tunnel data missing and mass STB offline.

Conditions:
LC double failure, secondary LC became active firstly.
The issued existed from V166.
