Hi list, I'm working under CentOS, so the kernel is 2.6.32-358.123.2.openstack.el6.x86_64. openvswitch.x86_64 1.11.0_8ce28d-1.el6ost
I have two physical machine in the test, each of them have a 10 Gb NIC card. The bandwidth between the two machine using iperf can achieve 9.41Gb/s. After enable gre follow guide http://networkstatic.net/configuring-vxlan-and-gre-tunnels-on-openvswitch/#!prettyPhoto The bandwitdth between the two nodes are really low. Only 122 Kbits/s !!!! Anyone know why this happen ???? Thanks. -chen My node 1: run command "iperf -c 10.1.2.11" ovs-vsctl show 218f9b54-b3e8-47ac-8563-58ff91ca57e9 Bridge br-int Port "gre1" Interface "gre1" type: gre options: {remote_ip="192.101.11.104"} Port br-int Interface br-int type: internal ovs_version: "1.11.0" ovs-ofctl dump-flows br-int NXST_FLOW reply (xid=0x4): cookie=0x0, duration=6542.818s, table=0, n_packets=1756, n_bytes=1436504, idle_age=5992, priority=0 actions=NORMAL ifconfig br-int Link encap:Ethernet HWaddr 7A:93:7F:77:B5:48 inet addr:10.1.2.10 Bcast:10.1.2.255 Mask:255.255.255.0 inet6 addr: fe80::e899:ff:fe32:df3f/64 Scope:Link UP BROADCAST RUNNING MTU:1500 Metric:1 RX packets:413 errors:0 dropped:0 overruns:0 frame:0 TX packets:507 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:32086 (31.3 KiB) TX bytes:690110 (673.9 KiB) eth0 Link encap:Ethernet HWaddr 00:25:90:79:D3:F4 inet addr:192.168.11.103 Bcast:192.168.255.255 Mask:255.255.0.0 inet6 addr: fe80::225:90ff:fe79:d3f4/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:53322614 errors:0 dropped:0 overruns:0 frame:0 TX packets:10325270 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:10586110139 (9.8 GiB) TX bytes:2822791581 (2.6 GiB) Memory:dfd20000-dfd40000 eth4 Link encap:Ethernet HWaddr 00:1B:21:D5:34:EC inet addr:192.101.11.103 Bcast:192.101.11.255 Mask:255.255.255.0 inet6 addr: fe80::21b:21ff:fed5:34ec/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:20351591 errors:0 dropped:0 overruns:0 frame:0 TX packets:9158853 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:28390873276 (26.4 GiB) TX bytes:12372083654 (11.5 GiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:1396 errors:0 dropped:0 overruns:0 frame:0 TX packets:1396 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:155046 (151.4 KiB) TX bytes:155046 (151.4 KiB) ethtool eth4 Settings for eth4: Supported ports: [ FIBRE ] Supported link modes: 10000baseT/Full Supported pause frame use: No Supports auto-negotiation: No Advertised link modes: 10000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: No Speed: 10000Mb/s Duplex: Full Port: Direct Attach Copper PHYAD: 0 Transceiver: external Auto-negotiation: off Supports Wake-on: d Wake-on: d Current message level: 0x00000007 (7) drv probe link Link detected: yes My node 2: run command "iperf -s" ovs-vsctl show 46b797bd-7982-4c73-b5f9-039506d48f1d Bridge br-int Port "gre1" Interface "gre1" type: gre options: {remote_ip="192.101.11.103"} Port br-int Interface br-int type: internal ovs_version: "1.11.0" ovs-ofctl dump-flows br-int NXST_FLOW reply (xid=0x4): cookie=0x0, duration=6777.408s, table=0, n_packets=1580, n_bytes=906468, idle_age=6029, priority=0 actions=NORMAL ifconfig br-int Link encap:Ethernet HWaddr 4A:01:B0:7C:64:43 inet addr:10.1.2.11 Bcast:10.1.2.255 Mask:255.255.255.0 inet6 addr: fe80::746b:58ff:fe17:e660/64 Scope:Link UP BROADCAST RUNNING MTU:1500 Metric:1 RX packets:512 errors:0 dropped:0 overruns:0 frame:0 TX packets:517 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:434200 (424.0 KiB) TX bytes:42046 (41.0 KiB) eth0 Link encap:Ethernet HWaddr 00:25:90:79:D2:5C inet addr:192.168.11.104 Bcast:192.168.255.255 Mask:255.255.0.0 inet6 addr: fe80::225:90ff:fe79:d25c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:53346180 errors:0 dropped:0 overruns:0 frame:0 TX packets:10328933 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:10596097803 (9.8 GiB) TX bytes:2828265083 (2.6 GiB) Memory:dfd20000-dfd40000 eth4 Link encap:Ethernet HWaddr 00:1B:21:A1:1A:18 inet addr:192.101.11.104 Bcast:192.101.11.255 Mask:255.255.255.0 inet6 addr: fe80::21b:21ff:fea1:1a18/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:49976926 errors:0 dropped:0 overruns:0 frame:0 TX packets:751929 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:27163063649 (25.2 GiB) TX bytes:51395221 (49.0 MiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:32 errors:0 dropped:0 overruns:0 frame:0 TX packets:32 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2278 (2.2 KiB) TX bytes:2278 (2.2 KiB) ethtool eth4 Settings for eth4: Supported ports: [ FIBRE ] Supported link modes: 10000baseT/Full Supported pause frame use: No Supports auto-negotiation: No Advertised link modes: 10000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: No Speed: 10000Mb/s Duplex: Full Port: Direct Attach Copper PHYAD: 0 Transceiver: external Auto-negotiation: off Supports Wake-on: d Wake-on: d Current message level: 0x00000007 (7) drv probe link Link detected: yes
