Class maps on 7200

What is the maximum number of class-maps that can be configured on Cisco 7200?

Re: Class maps on 7200

Hello Sumesh,

up to 64 class-maps can be invoked inside a single policy-map this provides capability to handle all possible classes in DSCP.

I don't know how many class maps can be configured on the device.

What are you trying to achieve?

Hope to help

"Q. How many classes does a Quality of Service (QoS) policy support?

A. In Cisco IOS versions earlier than 12.2 you could define a maximum of only 256 classes, and you could define up to 256 classes within each policy if the same classes are reused for different policies. If you have two policies, the total number of classes from both policies should not exceed 256. If a policy includes Class-Based Weighted Fair Queueing (CBWFQ) (meaning it contains a bandwidth [or priority] statement within any of the classes), the total number of classes supported is 64.

In Cisco IOS versions 12.2(12),12.2(12)T, and 12.2(12)S, this limitation of 256 global class-maps was changed, and it is now possible to configure up to 1024 global class-maps and to use 256 class-maps inside the same policy-map."
