All ports are configured for
five QoS device priorities.
VLANs 111 and 222 are
configured for QoS priority.
Ports 1 and 2 use 12 rules; 10 for implementing the 5 device
priority QoS instances and one each for implementing the
2 VLAN QoS instances (111 and 222).
Ports 3 and 4 use 11 rules; 10 for implementing the 5 device
priority QoS instances on 1 for implementing the single
VLAN QoS instance (VLAN 222).
The remaining ports use only ten rules for implementing
the five device priority QoS instances.
