Hello - We have just upgraded from a 2XT1 to a 4XT1 that connects our central office to 60 remote offices.Unfortunately, it's managed router (Verizon) so I can't get into it. However, I am using Netfow on it and I have noticed that no matter how much traffic we pump through it, we never go beyond 50% utilization. The reason we upgraded was because we were maxing out the 2XT1! It looks like something is still thinking there are only 2 T1s. Now, Verizon assures us that all 4 are being used, but I can't see it. I had to hold their hands to get them to configure Netflow correctly, so I think I will have to do the same here, what can I have them check? It is a 2800 series router connected to a 3000 concentrator which handles the L2L VPN to our sites. Thanks.
also - there are 4 T1 cards in the the 2851, all show green, and the Netflow collector recognizes it as having 6.14Mbps.
