Hi, I'm a longtime and very satisfied pfsense user. But I ran into an situation that I can not understand. Maybe you can give me a Clue what to do. Or where to look for infos.
I have Alix 2D3 Board with PFSense 2.0.1-RELEASE i386 running on my CF-Card. I switched recently to a new switch. A Cisco SG-300 28 gigabit ports (the Small Office version without IOS). To increase the bandwidth I switched from vr0 interface to a LAGG with vr0 and vr2 running in LACP Mode. I configured the switch to use LAG with LACP Enabled with LACP Timeout long. I use VLans on top of the vr0 and now on top of the LAG. When the system comes up everything looks good. But inside 1-5 Minutes the CPU gets eaten up from interrupts, up to 99.9% and then the system freezes. When I remove one of the links, the interrupt load goes down instendlty, and settles around 10-50% depending on the load of the interface. I can't enable the debug infos on the switch, there is no option for that. But the same configuration is used with Gigabitports on a RHEL6 Linux system without any Problems. I'm more a Linux kind of guy, so I don't know where to have a look what is using the interrupts. One thing I noticed is that I have Hardware Checksum offloading enabled, but Hardware TCP Segmentation Offloading und HW Large Receive Offloading is disabled under System - Advanced - Networking. I don't remember changing this, but the System was installed on PFSense 1.2 and updated when a new release came out. Is someone using this kind of switch or an Alix board with LAGG and LACP and can share his results? Thanks for this great product and for your help with this.
