АМАТЕК AN-SGM28P24-400 [102/322] Policy based qos

101 / 322

the mapping relation between the DSCP value and user configuration of the queue。

The cos-dscp type is an extension based on the DSCP type cos type, which is essentially a

DSCP type or a cos type。If the cos-dscp type is used, the IP message system will automatically

match the DSCP priority, and the non IP message system will be based on the cos priority。

According to the priority type (dscp/cos), the corresponding scheduling is carried out。

7.1.3 Policy based QOS

The QoS policy includes classes and policy actions. The class is used to identify the stream,

and the user can define a series of rules by the command to classify the packet; the policy action is

used to define the QoS action of the message of the matching rule。If a port enabled strategy based

on QoS, the switch will enter the port of packet classification, to meet the requirements of the

classification of data packets, packet switch will according to the strategy of action processing of

the port data corresponding to, does not meet the requirements of packet classification is not

processed, then the output queue according to the priority mapping the relationship between

decision of the packet。
