Combining 10g tap ports

[eric at roxanne.org (Eric Gauthier)]

Hello,

I'm wondering what are people's experience is with boxes, like those 
from Gigamon, to aggregate 10g span ports?  Any recommendations?

As background, we currently have a sensor network where we provide 
our InfoSec team with taps from various points in our network.  In
cases where we have redundant routers, we've taken a tap from each 
one, fed it into a switch, then span'ed the two ports into a third so 
that we can present them with a single feed for each location because, 
according to them, they can not re-assemble data from different 
interfaces on their sensors.  We have an "opportunity" to revisit this 
design now that we're moving to 10g router interlinks.

Eric :)
