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.
