Noel, Tom,

There are limitations on the 75xx's depending on the RSP/VIP setup you have.

It's a distributed platform that does software based forwarding when running in dCEF mode. All packet are switched by the VIPs and never touch the RP. Therefore the switching capacity is a function of the speed of the VIPs and the features you have enabled in the packet path (ACL's, QOS, etc..).

Doesn't the RP handle the timing on the CyBus (1.2 gbps) and doesn't it touch the packet when it travels between VIPs on different CyBUSes (7513 has 2)? Bus arbitration is done on the RP ?? The 7500 doesn't have CSC card like the 12k series

The short answer is there isn't a bandwidth concept like there is with the 72xx. However, you can overload the VIP with the right PA combination and features. The matrix of performance will depend on the features, ppps, and VIP type.

There have been extensive discussions about this on cisco-nsp so if there are further questions I'd suggest we move it over there and I can add more.

Thanks, Rodney

Hello,

We are moving from a Cisco 7206 to a 7513, and I was wondering if we will be limited by bandwidth points on the 7513 (as we are with the 7206). From the sparse documentation I've found so far, it doesn't appear that this limitation exists in the 7513, correct?

Off-list replies are welcomed.
