OVS doesn't have either of those. Network devices generally do have queues, but they aren't part of OVS and OVS doesn't have control over them. On Tue, Feb 02, 2016 at 03:44:50PM -0500, Jiaqi Zheng wrote: > According to my understanding, switch should have a input queue for each > input port, and

[ovs-discuss] switch queue size

2016-02-02 Thread Jiaqi Zheng
Hi All, I use OVS 2.3. Is there any command to set switch queue size ? i.e. buffer size. Larger queue size can accommodate more packets when congestion occurs. Thanks. Best, Jiaqi ___ discuss mailing list discuss@openvswitch.org http://openvswitch.org
