I'm pushing 20GE out using lagg right now (and fixing the er, amusing behaviour of doing so.) I'm aiming to hit 40 once I get hardware that doesn't get upset pushing that many bits. The netops people at ${JOB} also point out that even today switches occasionally get confused and "crash" a switchport. Ew. So yes, there are people using lagg, both for failover and throughput reasons. I'm working on debugging/statistics right now as part of general "why are things behaving crappy" debugging. I'll see about improving some of the peer reporting at the same time. -adrian On 21 July 2013 06:03, Barney Cordoba wrote: > > -------------------------------------------- > On Sat, 7/20/13, isp wrote: > > Subject: LACP LAGG device problems > To: freebsd-net@freebsd.org > Date: Saturday, July 20, 2013, 10:04 AM > > > > > Hi!
