I have this weird requirement that I am juggling right now and I wanted to reach out to larger audience: In this box I have 2 dualport ixgbe 10G cards. On ingress, I want to get data off of 2 ports of first 10G card and lagg/lacp them into 1 stream of data. But for outgoing, I want to have 2 identical streams of data going out on 2 ports of the second 10G card. (not load-balancing but more of a mirroring). The reason for this is, I need to be able to provide same data to 2 different application hosts downstream for monitoring. Something like: http://www.juniper.net/techpubs/en_US/junos13.2/topics/concept/port-mirroring-ex-series.html I believe a regular switch might be perfect but for I could not find anything simple in FreeBSD to do that. Luigi: Can netmap/vale be helpful here? Any other pointers would be really appreciated. Cheers, Hiren
