We have seen situations under heavy load where a VIP2-40 with an OC3 running at 80% and a Fast Ethernet PA running at 50% have resulted in severe packet loss and latency. After addressing this with our Cisco reps (including the Product Manager and Product Engineer for the 7513/VIP family) they acknowledged the problem and stated:
"We do not recommend putting any other PA into a VIP2-40 if an OC3-PA is already installed. We have seen adverse performance, in the way of latency and packet loss, resulting from such a configuration. Customer's choosing to do so, do so at their own risk".
This is not equivalent to
Cisco will not support multiple PA's within a VIP2-40.
My memory is that Cisco does not support use of two 'high speed' PAs in a single VIP2/40. I also wonder how you got a POS and anything else in a VIP, as the POS is secured in and uses both holes. Was it ATM-Lite or something kinky? randy
