Cisco 7513 & Bandwidth Points


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.

This is really more a cisco-nsp type question.

To answer, no, the 7500 doesn't have the bandwidth points issue the 7200s
have. Each VIP has its own PCI bus(es) for PAs and then connects to the/a
1gbit cybus.

7500s have a whole new set of scaling issues. :slight_smile:

As long as you don't believe the performance numbers someone at cisco made
up for the 7500 VIP datasheets, you'll be fine.

On-List replies perhaps may be usefull.. Or could you post a summary of
your findings?

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..).

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.
