[ovs-discuss] Interval /transmission timer for particular MPs in CFM

Hi, If we are using cfm_interval while creating cfm mpid then-- 1) Is that means it is for this particular Mpid.so it means we can configure different interval for different MPids? 2) along with that I want to know how can I see the current timer value by any show command for particular MPids, I

Hi Experts, Does anyone has this experience to control XenServer OVS with NOX controller? I recently setup two OVS on two separate XensServer, and configure two VLANs on them (vlan100 and vlan200). Without any controller, the VLAN configuration is working perfectly. The VMs in vlan100 can only tal

Hi, I connected br0 and br1 using a patch port. I tried to limit the rate on the link between br0 and br1 using this guide: http://openvswitch.org/support/config-cookbooks/qos-rate-limiting/ While its working well with normal ports it doesn't seem to have any impact on patch ports. Is that a bug o

OK. I'm glad it works with OVS 1.4.0. We are planning to keep OVS scripts in sync with upstream XenServer from now on (mostly, by not installing any scripts over the upstream XenServer versions), so with luck the problem will not recur. I imagine that there are few users of SR-IOV who install OV

The observation I had with the current XenServer 6.0 is, its working fine with default OVS-1.0.99. And not working with any new OVS, except OVS-1.4.0. That's the reason, I posted my observation. Thanks, Ramana Reddy. On Wed, Feb 15, 2012 at 11:39 PM, Ben Pfaff wrote: > We do our best to backpo

We do our best to backport fixes to earlier release branches when they are either important or easy to backport. The fact that this fix wasn't backported demonstrates that it didn't fall into one of those categories, or that we overlooked it. If you need the fix on an earlier version, you are fre
