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 :)
