Be careful when considering the Anue products. When we evaluated both Anue and Gigamon, we had to rule out Anue due to total lack of IPv6 support, and went with Gigamon instead. I have not heard whether the situation has changed in the last year. We liked both products for their functionality and ease of use, but for us IPv6 was the distinguishing capability.
