It looks like the driver is not passing packets from the VLAN layer to the NIC. Switch counters verify this and netstat seems to indicate the same. Apologies for any mistakes in the text, i had to convert from an image (attached). I've tried toggling flags on the igb interface (txcsum, hwtag, etc.) and nothing makes a difference. root@rtr-net-r1: - # netstat WI igb0 Name Mtu Network Address Ipkts lerrs Idrop Opkts 0 errs Coll igb0. 1500 <Link#1> ac:1f:6b:14:99:20 0 0 0 0 0 0 root@rtr-net-r1: - # netstat WI vlan202 Name Mtu Network Address Ipkts lerrs Idrop Opkts Oerrs Coll vlan202 1500 <Link#6> ac:1f:6b:14:99:20 0 0 0 0 2679 0 vlan202 - 10.1.202.0/24 10.1.202.123 0 - - 2678 *VLAN202 at the address layer has Opkts, but at the link layer it has Oerrs.* igb show no packets and tcpdump verifies this. root@rtr-net-r1: - # ipfw -a list 65534 3940 334356 allow log ip from any to any 65535 0 0 deny ip from any to any root@rtr-net-r1: - # ifconfig igb0 igb0: flags=8c02<EIRORDCRST,ORCTIVE,SIMPLEX,MULTICRST> metric 0 mtu 1500 options=4002a8<VLAN_MTU,JUMEIO_MTU,VLAN_HWCSUM,TS06,TXCSUM_IPV6> ether ac:1f:6b:14:99:20 hwaddr ac:1f:6b:14:99:20 nd6 options=29<PERFORMNUD,IFDISRBLED,RUTO_LINKLOCRL> media: Ethernet autoselect (1000baseT <full -duplex>) status: active root@rtr-net-r1: - # ifconfig vlan202 vlan202: flags=8843<UP,BRORDCRST,RUNNING,SIMPLEX,MULTICRST> metric 0 mtu 1500 ether ac:1f:6b:14:99:20 inet 10.1.202.123 netmask Oxffffff00 broadcast 10.1.202.255 nd6 options=29<PERFORMNUD,IFDISRBLED,RUTO_LINKLOCRL> media: Ethernet autoselect (1000baseT <full -duplex>) status: active igb0@pci0:1:0:0: class=0x020000 card=0x153315d9 chip=0x15338086 rev=0x03 hdr=0x00 vendor Intel Corporation device = '1210 Gigabit Network Connection' class network subclass = ethernet bar [10] = type Memory, range 32, base 0xdf400000, size 524288, enabled bar [18] = type I/O Port, range 32, base Oxe000, size 32, enabled bar [1c] = type Memory, range 32, base Oxdf480000, size 16384, enabled cap 01[40] = powerspec 3 supports DO D3 current DO cap 05[50] = MSI supports 1 message, 64 bit, vector masks cap 11[70] = MSI-X supports 5 messages, enabled Table in map Ox1c[0x0], PBR in map Ox1c[0x2000] cap 10[a0] = PCI-Express 2 endpoint max data 256(512) FLR NS link x1(x1) speed 2.5(2.5) RSPM L1(L0s/L1) ecap 0001[100] = REP 2 0 fatal 0 nonfatal 1 corrected ecap 0003[140] = Serial 1 ac1f6bffff149920 ecap 0017[1a0] = TPH Requester 1 igb1@pci0:2:0:0: class=0x020000 card=0x153315d9 chip=0x15338086 rev=0x03 hdr=0x00 vendor Intel Corporation device = '1210 Gigabit Network Connection' class network subclass = ethernet bar [10] = type Memory, range 32, base Oxdf300000, size 524288, enabled bar [18] = type I/O Port, range 32, base Oxd000, size 32, enabled bar [1c] = type Memory, range 32, base Oxdf380000, size 16384, enabled cap 01[40] = powerspec 3 supports DO D3 current DO cap 05[50] = MSI supports 1 message, 61 bit, vector masks On Fri, Sep 29, 2017 at 8:14 PM, Lee Brown <leeb@ratnaling.org> wrote: > Hi, > > I've been using FreeBSD for years, so I'm familiar with the setup. > > I just got a server, supermicro motherboard, 4 intel NICs, installed the > FreeBSD-11.1-RELEASE-amd64-disc1. uname reports FreeBSD11.1-RELEASE #0 > 321309. > > Unfortunately the igb NIC's don't appear to work correctly.
