QoS Setup
Enable QoS: Users can choose to Enable QoS (Quality of Service). If set to
“enable” QoS, the QoS will allow higher priority packets to pass
through the device.
Queuing Method: The methods for managing your queue. “Priority Queuing” is one
of the first queuing variations to be widely implemented. This is
based on the concept that certain types of traffic can be identified
and shuffled to the front of the output queue so that some traffic is
always transmitted ahead of other types of traffic.
Process TOS Field: An 8 bits field in the IP packet header designed to contain values
indicating how each packet should be handled in the network. If
you choose “enable” then it will enable this function to process the
IP Type of Service field.
Overwrite Policy
Priority:
Choose “Yes” to enable the IP packet TOS field priority to overwrite
the priority defined in the policy configuration.
