Thanks for your reply. I mean, if there is two group. One group use the ip_src and tcp_src as the fields of the hash, and the other group use the ip_dst and tcp_dst as the fields of the hash. If the ip_src == ip dst , and tcp_src == tcp_dst, Then will it is hashed to the same bucket id ?
ovs-ofctl add-group br-int "group_id=1001, type=select, selection_method=hash, fields(tcp_src,ip_src), bucket=bucket_id=1, actions=resubmit(,65), bucket_id, actions=resubmit(, 75)” ovs-ofctl add-group br-int "group_id=1002, type=select, selection_method=hash, fields(tcp_dst,ip_dst), bucket=bucket_id=1, actions=resubmit(,65), bucket_id, actions=resubmit(, 75)” Thanks. > 在 2019年12月17日，05:32，Ben Pfaff <[email protected]> 写道： > > On Mon, Dec 16, 2019 at 06:49:47PM +0800, 贾乘 wrote: >> I have one question about the hash of the group.
