4948 is essentially a fixed-config 4500 w/ SupV (400MHz processor). I
don't have numbers on that, but I did ask Cisco about GRE performance on
the Sup6-e (1.3GHz proc) and was told that it can do about 160k 64-byte
packets/second. That's less than 100Mb, though I'm not sure how packet
size impacts CPU utilization.

Hi All,
Does anybody have any idea the impact of running multiple GRE tunnels
on a 4948 switch?
I can see that it will be processed by software rather than hardware,
but just how much of a problem is this likely to be?
I am only talking about a max of 100M of GRE traffic, amongst a couple
of Gig of total traffic.
thanks
