Traffic provisioning
For the IEEE 802.1Q VLAN tagging mode with oversubscription support (QoS_osub =
enabled) it is recommended not to use the n- classes, otherwise all frames will always
be marked yellow (i.e. they will have a higher dropping precedence; p0 = 0). In the
provider bridge mode, any assignment of an n- class will be recognized as the related n
class (tolerant system behavior for inconsistent provisioning).
Traffic class to queue assignment
The assignment of the traffic classes to the egress queues is as follows:
Transparent tagging
Traffic class
3, and Internal
use
2
1
0
Notes:
1. "Internal use" means that the queue is used for network management traffic (spanning
tree BPDU's or GVRP PDU's, for example).
