Re: [ovs-discuss] Failed to add ovs bridge

I am not using STP/RSTP.I saw the bug fix you mentioned, seems it is irrelevant to my problem. May be there is some race condition lead to deleting netdev in netdev_shash. But, I cannot figure it out right now. The occurrence probability is very low. I just hit this for three times in two

Re: [ovs-discuss] Anyway to move/load data between ct_mark/ct_label and field/register ?

What's your high-level goal? Most fields will be the same on every trip through the connection tracker for a given (half-)connection, so there would be limited value in that. On Thu, May 11, 2017 at 02:37:13PM +, Zang MingJie wrote: > It can only set to immediately value, I want to copy some

Are you using STP or RSTP? There's a bug fix related to them on branch-2.5. On Thu, May 11, 2017 at 11:11:02AM +, fukaige wrote: > Hi all, > > Occasionally, I get error when creating a bridge using “ovs-vsctl add-br > br-eth” > > > ovs-vsctl: Error detected while setting up 'br-eth'.

Hi, I just want to conntrack tcp flows for testing. But when I put the follow command into CLI, ovs-ofctl add-flow "in_port=1, tcp, ct_state=-trk, action=ct(table=1)", with few seconds gone, I get such output info at CLI, "netlink: Unknown conntrack attr (2) openvswitch: netlink: Flow

Re: [ovs-discuss] a struct to keep flow scores

OVS already has mechanisms for this kind of thing. For datapath flows, OVS already evicts flows based on these criteria. For OpenFlow flows, OVS already supports approximate-LRU eviction. I'm not sure what you're going to additionally get out of adding more to these mechanisms. Do you have a

Re: [ovs-discuss] a struct to keep flow scores

OK. I'm not certain why you need new high-level data structures for this. The code already propagates information from the datapath into the OpenFlow flows and I think that you can just follow the existing pattern to convey your new data. On Thu, May 11, 2017 at 01:50:32PM +, Avi Cohen (A)

Re: [ovs-discuss] a struct to keep flow scores

Thanks Ben, We need to test another eviction criteria - not LRU, but learn the flows other scores such as flow effective time / flow usage , and to do eviction based on these scores Best Regards avi > -Original Message- > From: Ben Pfaff [mailto:b...@ovn.org] > Sent: Thursday, 11 May,
