https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D268490 Bug ID: 268490 Summary: [igb] [lagg] [vlan]: Intel i210 performance degraded Product: Base System Version: 12.4-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: dd@goboomtown.com I have a ZFS file server running ctld to provide an iSCSI target to VMware hosts. It runs on a Supermicro motherboard which has dual Intel i210 ports = on it. The igb ports are configured in a LACP lagg with the switch, and then v= lan is used to create 4 VLAN interfaces on top of that. The system has been rock solid stable in production for over a year on 12.2-STABLE. Upgrading it to 12.4-RELEASE 2 weeks ago rendered it unusable as an iSCSI target. I've tried disabling all the HW options to no avail. The ctld iSCSI target lives on VLAN 8 (172.27.6.135). When I try to connect= to the target from VMware's initiator, VMware basically hangs and I start seei= ng interface errors accumulate on this machine. Once I saw this behavior, I assumed it was a lower-level network issue and not specific to ctld at all.= I then removed the VMware iSCSI configuration and focused on diagnosing the lower-level network. Here's a pair of iperf tests performed on a neighboring FreeBSD 12.4 machin= e on the same VLAN segment (172.27.6.135) which has an igb interface without lagg+vlan. The first test is to this machine's lagg0.8 interface (172.27.6.135), and the second test is to a third machine (172.27.6.129) wh= ich also has an igb interface without lagg+vlan: $ for ip in 172.27.6.135 172.27.6.129; do iperf -c ${ip}; done ------------------------------------------------------------ Client connecting to 172.27.6.135, TCP port 5001 TCP window size: 32.0 KByte (default) ------------------------------------------------------------ [ 1] local 172.27.6.130 port 22350 connected with 172.27.6.135 port 5001 [ ID] Interval Transfer Bandwidth [ 1] 0.00-20.54 sec 43.1 KBytes 17.2 Kbits/sec ------------------------------------------------------------ Client connecting to 172.27.6.129, TCP port 5001 TCP window size: 35.0 KByte (default) ------------------------------------------------------------ [ 1] local 172.27.6.130 port 11072 connected with 172.27.6.129 port 5001 [ ID] Interval Transfer Bandwidth [ 1] 0.00-10.01 sec 1.15 GBytes 984 Mbits/sec Here's this machine's config from /etc/rc.conf: ifconfig_igb0=3D"mtu 9000 media 1000baseTX mediaopt full-duplex -rxcsum -rx= csum6 -txcsum -txcsum6 -lro -tso -vlanhwtso -vlanhwtag -vlanhwcsum -vlanhwfilter = up" ifconfig_igb1=3D"mtu 9000 media 1000baseTX mediaopt full-duplex -rxcsum -rx= csum6 -txcsum -txcsum6 -lro -tso -vlanhwtso -vlanhwtag -vlanhwcsum -vlanhwfilter = up" cloned_interfaces=3D"lagg0" ifconfig_lagg0=3D"up laggproto lacp laggport igb0 laggport igb1 lacp_fast_timeout" vlans_lagg0=3D"6 7 8 10" ifconfig_lagg0_6=3D"inet 172.27.6.10/26 mtu 1500" ifconfig_lagg0_7=3D"inet 172.27.6.123/26 mtu 1500" ifconfig_lagg0_8=3D"inet 172.27.6.135/28 mtu 9000" ifconfig_lagg0_10=3D"inet 172.27.6.251/26 mtu 1500" Here's this machine's relevant ifconfig output: igb0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000 options=3D800028<VLAN_MTU,JUMBO_MTU> ether 00:25:90:d6:e6:72 media: Ethernet 1000baseT <full-duplex> status: active nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> igb1: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000 options=3D800028<VLAN_MTU,JUMBO_MTU> ether 00:25:90:d6:e6:72 hwaddr 00:25:90:d6:e6:73 media: Ethernet 1000baseT <full-duplex> status: active nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> lagg0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 90= 00 options=3D800028<VLAN_MTU,JUMBO_MTU> ether 00:25:90:d6:e6:72 laggproto lacp lagghash l2,l3,l4 laggport: igb0 flags=3D1c<ACTIVE,COLLECTING,DISTRIBUTING> laggport: igb1 flags=3D1c<ACTIVE,COLLECTING,DISTRIBUTING> groups: lagg media: Ethernet autoselect status: active nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> lagg0.8: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu = 9000 ether 00:25:90:d6:e6:72 inet 172.27.6.135 netmask 0xfffffff0 broadcast 172.27.6.143 groups: vlan vlan: 8 vlanpcp: 0 parent interface: lagg0 media: Ethernet autoselect status: active nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> --=20 You are receiving this mail because: You are the assignee for the bug.=
