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-net&m=130929760904438 Any idea what might be the problem? Any improvements in 9.2-RC4 in this regards? Thank you in advance, -- Rumen Telbizov Unix Systems Administrator <http://telbizov.com>;
