Re: [ovs-discuss] ovs-vsctl set-manager command

Thanks for your quick reply. So, is it required to "set-manager"? I did not understand the need for the command. Also, when I try to set the remote IP using ovsdb-server --remote=ptcp:6640:10.107.48.192 I get the following: 2016-04-23T16:05:29Z|1|socket_util|ERR|6640:10.107.48.192: bind: C

Yes, I apologize for the mistake... I had a too quick look to one of the last capture. Checking better the captures and the standard... The datapath_id is included only in the OFPT_FEATURES_REPLY packet sent from the switch to the controller during the handshake. When you received a packet (e

Dear Ben, I discovered the issue in visualization of port options. Indeed, "show" command is working properly, but there is a problem in the application of some of the options. As a example, after applying: > sudo ovs-ofctl mod-port br0 2 down -O OpenFlow13 > sudo ovs-ofctl mod-port br0 2 no

[ovs-discuss] ovs clears user defined ingress policing rule on interface

Hi, 1. setup tc ingress policing rule on interface 2. ovs-vsctl add-port the port to ovs bridge. 3. the ingress rules will be clear by ovs. That the default ingress_policing_rate == 0 in ovsdb clears the tc configuration. I think ovs should have some way to avoid overwriting user configuration. _

Please don't drop the mailing list. OK, you're talking about TCP sequence numbers. Thanks, that helps. The code for select groups can't efficiently access the sequence number for a TCP packet, since that varies on a packet-by-packet basis and would defeat caching. On Thu, Jun 02, 2016 at 01:36:

Hi John, Thanks your reply. Seems you have covered everything :) The development work can be broken down in 3 parts: 1, add ovn driver to networking-sfc 2, provide APIs in networking-ovn for networking-sfc 3, implement the sfc in ovn So what about we take part 1 and part 2, and you take part 3?
