Hello, I was performing some stress testing to a NV3430. When I applied an ACL to the WAN interface the CPU usage increased to 82 % while when I performed a similar test using QoS, the CPU usage was 72%.
In both scenarios I had a 35MB bandwidth. This behavior seems unusual to me. If someone could give me some feedback, I'll appreciate.A

First you may want to look at upgrading your unit as the firmware is pretty old 10.9.4 is the current extended maintenance release, although your firmware number is higher it is actually more then a few years old, Adtran unified it's firmware numbering scheme more then two years ago making 10.X the newest line to all products. . And finally I think you maybe pushing the limits of a 3430 the 3430 was designed to be used for two T1 upstream connections which is 3MB of bandwidth, the two Ethernet ports are designed more with internal connections in mind, although other configurations are possible. I think you maybe pushing the 3430 a little harder then it was designed for and I would recommend upgrading to a 4430 or off loading the firewalling to a firewall device. Just my opinon based on the way I read the product literature for the 3430.
