Configuration Guidelines
Based on the requirements, you can map the packets into different queues by setting CoS
Priority .
If CoS Type is set to VLAN Priority , IPTOS or DSCP , generally, you can map the packets
into the proper CoS Priority according to the priority information contained in the packets.
At the application layer, if a service (for example, VOIP, video conference, video conferencing
call, and video on demand) has higher requirements for QoS, set a higher priority for the service
to get better bandwidth and service guarantee. To ensure good bandwidth multiplexing, be sure
to avoid a larger ratio of real-time services in the network. For a service (for example, Internet
access, E-Mail, and FTP) that has lower requirements for QoS, set a lower priority for the service
to provide better bandwidth sharing and contention mechanism.
