I think there's still some problems with LACP in the ixgbe 2.4.4 code. When I use 2.4.4, I am able to establish the LACP link, as stated below. Pi= ngs, and light traffic all works well. However, if I start driving some hea= vier NFS traffic 20-40+ MB/s) across the link from an ESXi server, I run i= nto networking issues where the NFS shares hosted by FreeBSD over the ixgbe= LACP link disappear, timeouts on the ESXi end, etc. If I set the FreeBSD ixgbe ports to FEC instead of LACP, everything continu= es to work. This is on FreeBSD 9.0-STABLE as of March 17th. My feeling is that something subtle is wrong still in the LACP code for ixg= be? LACP links for bce work fine under the same Dell PowerConnect switch, but t= hose are 1 gig links, not 10 gig links. In my tests, my LAG is set to Dyna= mic, not static, and has the proper MTU's (all set to 9000).=20 Only with LACP mode for the laggport do I have these problems.=20 How can I help Jack (or others) diagnose and test this further? Thanks. -----Original Message----- From: owner-freebsd-stable@freebsd.org [mailto:owner-freebsd-stable@freebsd= .org] On Behalf Of Chris Forgeron Sent: Tuesday, March 06, 2012 7:01 PM To: freebsd-stable@freebsd.org Subject: ixgbe v2.3.11 won't negotiate LACP, v2.4.4 does I have a few systems with Intel X520-DA2 PCIe network cards (10 Gig). The problem I've been running into is with a fresh 9.0-STABLE or 9.0-RELEAS= E install. I can't get a LACP connection established over the ix0 and ix1 p= orts. It's showing COLLECTING and DISTRIBUTING, but not ACTIVE.=20 I've noticed that older 9.0-BETA copies with the 2.3.10 ixgbe driver are wo= rking with the same switch without problems. The 9.0-STABLE that I was doing the most work with had an ixgbe of 2.3.11 After some digging around, I downloaded the ixgbe 2.4.4 from the Intel sit= e, compiled the .ko (a little editing due to the bool typdef), and now my 9= .0-STABLE systems can properly setup a LACP link over ixgbe devices. I'm sure others will run into this in time - Can we get the 2.4.4 into 9-S= TABLE?=20 Thanks. _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscribe@freebsd.org"
