Re: Cisco 7513 & Bandwidth Points

[Rodney Dunn <rodunn () cisco com>]

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.

Thanks,
Rodney
