Displaying the BA Classifier Configuration
To display the BA classifier configuration on the ATM router module interface, use the following
privileged EXEC command:
Example
In the following example, the show class-map command displays the configuration of the class-maps:
Switch1# show class-map
Class Map match-any class-default (id 0)
Match any
Class Map match-all ABC-signaling-host (id 3)
Match access-group 101
Class Map match-all mark-video (id 5)
Match access-group 151
Class Map match-all mark-voice (id 6)
Match access-group 150
Class Map match-all hipri (id 4)
Match ip precedence 2
Class Map match-all voice (id 2)
Match ip precedence 3 5 6 7
Switch1#
Configuring Output Policy Map
Consider the following key item when configuring IP to ATM QoS on an enhanced ATM router module:
• There is a maximum of four scheduler classes that can be used.
• The four scheduler classes are configured on the output policy map with the “bandwidth” command.
• The maximum cumulative bandwidth that can be configured in the four policy maps is 1Gbps, but
only 500 Mbps can be allocated.
Note See the “Calculating the Scheduler Class Weights” section for information on calculating weights and
bandwidth for IP QoS queues.
In the example network shown in Figure 25-11, the following four classes are used to decide what
bandwidth associated with each of the four classes. All traffic will eventually be mapped to these four
classes. In the example network, the 500 Mbps is allocated as follows:
• Voice—200 Mbps
• Video—175 Mbps
• Hi Priority IP—100 Mbps,
• Default IP— 25 Mbps
Command Purpose
show class-map [class-name] Displays the class map information.
