Hello all,
I've installed and configured openvswitch 2.3.1 on 3 machines (ubuntu
15.04). I've created a bridge with two interfaces in LACP balance-tcp.
I also added some fake bridges with vlan tags.
The problem i have is when I ping one of the fake bridge, the first
ping is lost (unless there is a tcp connection already up!):
PING 10.10.22.11 (10.10.22.11) 56(84) bytes of data.
64 bytes from 10.10.22.11: icmp_seq=2 ttl=64 time=0.419 ms
64 bytes from 10.10.22.11: icmp_seq=3 ttl=64 time=0.361 ms
Are you sure that's not just an empty arp cache?
Here is the configuration:
ovs-vsctl add-br br-main
ovs-vsctl ovs-vsctl add-bond br-main bond0 em1 em2
ovs-vsctl set port bond0 bond_mode=balance-tcp
ovs-vsctl set port bond0 lacp=active
ovs-vsctl add-br br-data br-main 22
ip addr add 10.10.22.11/24 dev br-data
LACP seems fine:
---- bond0 ----
status: active negotiated
sys_id: 34:64:a9:9a:5f:00
sys_priority: 65534
aggregation key: 1
lacp_time: slow
The machines have broadcom BCM5720 interfaces using tg3 drivers.
Also, i guess it's linked, DNS queries coming out this interface
timeout most of the time. But if i ping the DNS server while doing an
nslookup, it works fine.
Anyone knows what is the problem?
Could still be an arp problem. Run "arp" before and after trying to send
those requests. If it's an arp problem, it should always be the first
packet that gets lost and all subsequent packets/requests should be fine.
Best,
Luke
