# iftop -i aggr2
and this almost works - the numbers are definitely wrong (way too small)....
(I'm getting several hundred bytes per second tops while it should be at least
20MB/s). I guess I'm seeing only icmp traffic from ipmp probing. Yes, that's
what I'm seeing as unless I specify -p (promisc) it can only see traffic to an
IP address which is directly configured on aggrN. It would be fine if IPMP was
not configured but with IPMP on it is non-intuitive.
But the real problem is that it doesn't allow to listen on ipmp0 and IMHO it
should.
