14.7 Default Bandwidth Management Classes and Priorities
If you enable bandwidth management but do not configure a rule for critical traffic like VoIP,
the voice traffic may then get delayed due to insufficient bandwidth. With the automatic traffic
classifier feature activated, the ZyXEL Device automatically assigns a default bandwidth
management class and priority to traffic that does not match any of the user-defined rules. The
traffic is classified based on the traffic type. Real-time traffic always gets higher priority over
other traffic.
The following table shows you the priorities between the three default classes (AutoClass_H,
AutoClass_M and Default Class) and user-defined rules. 6 is the highest priority.
