Be careful. Cisco recognizes that VIP2-40's with OC3-PA's and any other PA co-habitating the VIP card will cause problems (packet loss under peak conditions). This is due to the huge overhead the SARing takes on the VIP's CPU. Cisco will not support multiple PA's within a VIP2-40. This is the primary reason they came out with the VIP2-50.

I just have a quick qustion. I'm in the process of determining weather or not to purchase several VIP cards and modules for a few 7513's I have at remote locations accross the United states. I spoke with some friends I have at cisco in referance to known related problems with the VIP cards (according to cisco there were close to non) but I am interested in some input from people who are already using VIP cards on 7513's.
Thanks, Rob
We have VIP2-40s running all over our network with various port adapters (OC3, 8port serial etc) and have had no problem besides flakiness when we first implemented them. Everything is working well now. brad reynolds ber@cwru.edu brad@iagnet.net

I do not believe this statement to be true.
They do not currently support multiple PA's within a VIP2-40 when an OC3 ATM-Lite PA is present. In fact not only is it not supported, but the IOS will complain if it detects this and will not bring the other PA on line. /cvk
what they won't support, I believe, is anything in the second adapter slot after the first PA-(the 0c-3 atm thingie) is installed....limitation has to do with the PA- (oc-3 atm), only. TE On Wed, 10 Dec 1997, Randy Bush wrote:

It depends on the PA. They certainly don't support multiple OC3 (POSIP or ATM) PAs in the same VIP2-40. I am not sure if they will in the future, but right now it doesn't work. You can certainly put multiple HSSI PAs on a VIP2-40 ---CJ From: Randy Bush <randy@psg.com> Subject: RE: Cisco Vip Cards. > Cisco will not support multiple PA's within a VIP2-40.
