At least on Cisco switches, it takes ~45 seconds for the switching topology to converge with STP disabled. Shorter periods if you enable portfast or uplinkfast. What is meant, I believe, is that the port should be configured as an edge port (spanning-tree portfast [trunk] in cisco lingo, set edge for junipers). You don't ever want to disable STP anywhere - that's just a recipe for disaster.

Re: FreeBSD 9.1 ix driver vlan problem
Hello everyone, Here are the final results of my tests: 1. I reinstalled the router with vanilla 9.2-RC4 and performed the same tests - the results were exactly the same. The problem persisted. 2. Then I applied the patch provided by Oleg and recompiled kernel. This indeed did *fix* the problem and now creating/destroying vlans does NOT cause the interface to flap at all. All the symptoms that I was experiencing seem to be gone. Thank you so very much Oleg and Dmitry! Appreciated. Jack, at this point I am wondering what your opinion on the patch is? Do you approve it for production use yourself or do you think it needs to reworked? Also any plans of incorporating this in -STABLE ? Again, I'd like to thank everyone who helped here and especially Oleg, Dmitry and Jack. Thanks guys!

Re: FreeBSD 9.1 ix driver vlan problem
I will look into this.

Basically I am building a brand new FreeBSD 9.1-RELEASE router which has a dual port fiber NIC (X520-SR2 10GbE Dual-Port Server Adapter (82599ES) 10GBASE-SR - LC). The network card is recognized fine by the ix driver and overall works fine. The issue is when I start adding vlans to this card. It seems like every time I add a brand new vlan it freezes all the rest of the vlans already configured on that one physical interface. I loose ping between my locally connected peers. Example: ifconfig vlan200 create # this is OK ifconfig vlan200 inet 1.2.3.1/30 vlan 200 vlandev ix1 description DEBUG # this second line makes the rest of the vlans freeze for 6-7 seconds On the switch side (Juniper) the physical interface flaps. There's nothing in logs/dmesg. If I configure the above vlan on an em0 interface - things are just smooth. I read some similar complaints that have surfaced in the past: * http://readlist.com/lists/freebsd.org/freebsd-net/5/26378.html * http://marc.info/?l=freebsd-netm=130929760904438 Any idea what might be the problem?

Disable spanning tree on the port and the reset will be very short.

Re: FreeBSD 9.1 ix driver vlan problem
Rumen, I'd like to know if you can check the spanning tree setting as Daniel mentioned and if that solves it, I do know that that can cause considerable delay in link transitions. Also, can you see if you see different behavior by going to the latest 9.2 bits? Oleg thanks for the patch, I will check it out and have my validation engineer do some tests and we'll get to the bottom of this.

Re: FreeBSD 9.1 ix driver vlan problem
Hi Jack, Thanks for the suggestions and looking into this. Here are a few additional bits of information that you requested: 1. We did disable spanning tree on the switch port and the result of that is that basically now creating/destroying a vlan on the ix interface makes it freeze for about 3 seconds from previously 6. 2. I brought manually the physical interface down (ifconfig ix1 down) and then up and measured the time it took for the interface on the switch to show as up - and that was again about 3 seconds. So basically it seems to me like that's how long it normally takes for a link to be negotiated. 3. We tweaked a setting on the switch which instructs the port to be down for 5 seconds before it's considered down. Then repeated the test again and the result was that now the freeze period got reduced to 1.5 seconds and no ping packets were lost but one of the packets returned with 1500 ms delay. My guess on this one is that since the switch ignored the flapping of the interface, bringing it back up was much faster. So it does mask the problem somewhat but it is still there - the interface seems to go down. Next steps: 1. I will reinstall this machine with the latest 9.2 and repeat the tests see what happens. 2. If the previous one fails - I'll try the patch that Oleg sent. Thanks a lot for providing that patch. I'll update this list with more findings.

Re: FreeBSD 9.1 ix driver vlan problem
Why would disabling STP on the switch *shorten* the amount of time it takes for the port to come up? At least on Cisco switches, it takes ~45 seconds for the switching topology to converge with STP disabled.

I'll come back to the list with my results. It would be really nice if Jack et al could test that patch themselves and endorse/incorporate into future FreeBSD releases.

So what I am going to do right now is reinstall with 9.2 and recompile the driver with your patch. I'll come back to the list with my results. FWIW, we're (with oleg@, yeah) using this patch on stable/9, so you're welcome to test this on your 9 It's supposedly way too late to try to include this fix into 9.2-R, but maybe it's worth the errata notice... -- Sincerely, D.Marck [DM5020, MCK-RIPE, DM3-RIPN] [ FreeBSD committer: ma...@freebsd.org ] *** Dmitry Morozovsky --- D.Marck --- Wild Woozle --- ma...@rinet.ru *** ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org
FreeBSD 9.1 ix driver vlan problem
Hello Jack, list, I've been dealing with a nagging problem for a day now and decided to ask a quick question here. Basically I am building a brand new FreeBSD 9.1-RELEASE router which has a dual port fiber NIC (X520-SR2 10GbE Dual-Port Server Adapter (82599ES) 10GBASE-SR - LC). The network card is recognized fine by the ix driver and overall works fine. The issue is when I start adding vlans to this card. It seems like every time I add a brand new vlan it freezes all the rest of the vlans already configured on that one physical interface. I loose ping between my locally connected peers. Example: ifconfig vlan200 create # this is OK ifconfig vlan200 inet 1.2.3.1/30 vlan 200 vlandev ix1 description DEBUG # this second line makes the rest of the vlans freeze for 6-7 seconds On the switch side (Juniper) the physical interface flaps. There's nothing in logs/dmesg. If I configure the above vlan on an em0 interface - things are just smooth. I read some similar complaints that have surfaced in the past: * http://readlist.com/lists/freebsd.org/freebsd-net/5/26378.html * http://marc.info/?l=freebsd-netm=130929760904438 Any idea what might be the problem? Any improvements in 9.2-RC4 in this regards?
