1. By default, the mapping relation between tag and the CoS Priority is:
(0-7)-TC1, (8-23)-TC0, (24-31)-TC1, (32-47)- TC2, (48-63)- TC3.
2. Among the priority levels TC0-TC6, the bigger value, the higher
priority.

Description
The classofservice queue mode command is used to configure the
Schedule Mode. To return to the default configuration, please use no
classofservice queue mode command. When the network is congested, the
program that many packets complete for resources must be solved, usually
in the way of queue scheduling. The switch will control the forwarding
sequence of the packets according to the priority queues and scheduling
algorithms you set. On this switch, the priority levels are labeled as TC0,
TC1,TC2 … TC6.
