Hi ALL !
I have several servers with FreeBSD 8.0-PRERELEASE on SuperMicro with
different Intel NICs. When I create new vlan on em interface
( ifconfig vlan557 create vlandev em0 vlan 557),
it hangs down and then up and server becomes inaccessible by ssh, but
reply on icmp request.
on amd64, custom kernel:
em0@pci0:13:0:0: class=0x020000 card=0x108c15d9 chip=0x108c8086
rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = 'Intel Corporation 82573E Gigabit Ethernet Controller
(Copper) (82573E)'
class = network
subclass = ethernet
em1@pci0:14:0:0: class=0x020000 card=0x109a15d9 chip=0x109a8086
rev=0x00 hdr=0x00
vendor = 'Intel Corporation'
device = 'Intel PRO/1000 PL Network Adaptor (82573L)'
class = network
subclass = ethernet
on i386, GENERIC kernel:
em0@pci0:2:1:0: class=0x020000 card=0x11798086 chip=0x10798086 rev=0x03
hdr=0x00
vendor = 'Intel Corporation'
device = 'Dual Port Gigabit Ethernet Controller (82546EB)'
class = network
subclass = ethernet
em1@pci0:2:1:1: class=0x020000 card=0x11798086 chip=0x10798086 rev=0x03
