Hi, everyone.
Recently, we met a strange problem. We use Openstack by openvswitch. The
network node(physical server) crashes when vm send TCP packages. By my
analysis, the information of the physical nic (public network nic) is below:
[r...@server-65.0.aa.ustack.in ~ ]$ ethtool -i eth1
driver: bnx2
version: 2.2.4
firmware-version: 6.2.12 bc 5.2.3 NCSI 2.0.11
bus-info: 0000:01:00.1
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no
[r...@server-65.0.aa.ustack.in ~ ]$ ethtool eth1
Settings for eth1:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Supported pause frame use: No
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Advertised pause frame use: No
Advertised auto-negotiation: Yes
Speed: Unknown!
Duplex: Unknown! (255)
Port: Twisted Pair
PHYAD: 1
Transceiver: internal
Auto-negotiation: on
MDI-X: Unknown
Supports Wake-on: g
Wake-on: d
Link detected: no
The physical NIC is :
Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit
Ethernet (rev 20)
The version of OVS is 2.1.2, the version of kernel
is 3.12.21-1.el6.x86_64.
Did anyone met the compatibility between ovs and physical nic?
Thx
