Known Affected Releases

Fuji-16.7.1

Description (partial)

Symptom:
When migrating a CBR from 32QAM to 40QAM, customer tear down existing 32 channels, then rebuild to 40 and add the new primary channels.  During this process we found that there is a small chance that Multicast (DSG) tunnels will not be torn down properly which will result in ?phantom? tunnels on one or more mac-domains.   If a ?phantom? muticast tunnel is present, we will start to see ?Q full? messages on that linecard.



Version: V16.7.3

Conditions:
adding more channels in controllers and mac-domain
