We did a lot of NAC installations at different customers in different markets with Enterasys, Cisco, HP, and Juniper edge devices. With that experience we have a big difference between this vendors in case of debugging and troubleshooting. On the Enterasys edge devices we are missing a lot of functions especially for debugging at authentication, authorization, policy use and packet block/forward at port level. We would like to see more of these functions in future releases of software at B/C/G/D-Series, EWC and 7100s. Volker
