Not reset interface when adding VLAN

dominique.fournier · Dec 13, 2012, 10:27 AM

I put a bug request https://redmine.pfsense.org/issues/2716 explaining that :
When I add a vlan, the interface resets or all VLANS are dropped before returning. All the connections are drop, CARP is going in strange mode.

Chris suggest it is a network card problem. How can I diagnose this ? Theorically, it should be a e1000 card, but I don't know enough BSD to confirm that on command line.
The interface is name "em2"

Any help ?

Thanks

You can find out some more about the card from it's sysctl entries. Like so:

Looks like a dual port card with Intel 82574L Gigabit Ethernet chips, correct?
There will be many people running that chip without issue. :-\

dominique.fournier · Dec 13, 2012, 1:06 PM

It is only one port card Gigabit ethernet
