Limitation in class-map configuration in QOS

[gaurav_saxena]

We are using CBWFQ for QOS in MPLS PE router for all vpns. We are configuring about 256 VPNs, each VPN with five classes of services. The 7507 router is not allowing us to configure class-maps more than 1023. We have to configure total 256*5 = 1280 class maps. Is there any limitation on total number of class-maps in 7507 router??

Are you sure you really need that many? The same class can be re-used in many policy maps.

in one policy map we can configure max 64 Class-maps in CBWFQ. I got the answer , we can configure maximum 1024 global class maps on a router.

Thanks
