Hello all,
I have a question regarding the interface speed of GRE tunnels. I have created a GRE tunnel between two instances of OVS and am able to pass traffic through the tunnel. The command used to configure the tunnel(s) was:
ovs-vsctl add-port br0 gre0 -- set interface gre0 type=gre options:remote_ip=address
My question is that when I show the interface using ovs-ofctl br0 show, OVS reports the port speed as 100Mbps even though I am using a 1G NIC:
2(gre0): addr:82:34:a7:24:07:d4
config: 0
state: 0
speed: 100 Mbps now, 100 Mbps max
Is this normal behavior? This information seems to indicate to me that OVS may be limiting the GRE tunnel to 100 Mbps. I have tried to set the port speed through the configuration options but cannot get it to change.
Thanks,
Jeff
