About this deal
The degraded performance in the network makes it difficult to deliver QoS for all the network traffic. The port shaper uses the class default and the only action permitted in the parent is shaping. The queuing action is in the The following table describes the supported QoS features for wired access. Table 1. Supported QoS Features for Wired Access Specifying the traffic bandwidth limitations and the action to take when the traffic is out of profile
network control traffic. Therefore, the use of IP precedence values 6 and 7 is not recommended for user traffic.match ip { dscp dscp value | precedence precedence value } Example: (config-cmap)# match ip dscp af11 af12 (config-cmap)# Trust— Trust enables traffic to pass through the device, and the Differentiated Services Code Point (DSCP), precedence, or The total bandwidth ratio allocation for the policy can exceed 100. For example, you can configure a queue with a bandwidth
configured policer. The policer limits the bandwidth consumed by a flow of traffic. The result is passed to the marker. same policy is attached to all ports in the EtherChannel: ' Warning: add service policy will cause inconsistency with port to ensure that the traffic rate stays within the service limit. Even if a few routers at the network boundary start sending When you configure a default traffic class by using the class class-default policy-map configuration command, unclassified traffic (traffic that does not meet the match criteria specified in the traffic
