Hi
Sorry to bother others. My program breaks with datapath leaves the
network (HP switch). There are some errors returned by the
send_openflow_command, which I dont understand. Is there any document
on the meaning of the error?
00079|openflow|WARN:stream: send error: Broken pipe
00080|routingMR|ERR:OpenFlowMR::install_flow: flow-mod command to dpid
f7cae4000064 : error 32
00081|openflow|WARN:stream: send error: Bad file descriptor
00082|routingMR|ERR:OpenFlowMR::install_flow: flow-mod command to dpid
f7cae4000064 : error 9
00083|openflow|WARN:stream: send error: Bad file descriptor
not successfully opf command: routingMR::send_stats_request()
00084|openflow|WARN:stream: send error: Bad file descriptor
not successfully opf command: routingMR::send_stats_request()
00085|openflow|WARN:stream: send error: Bad file descriptor
00086|routingMR|ERR:OpenFlowMR::install_flow: flow-mod command to dpid
f7cae4000064 : error 9
00087|openflow|WARN:stream: send error: Bad file descriptor
00088|routingMR|ERR:OpenFlowMR::install_flow: flow-mod command to dpid
f7cae4000064 : error 9
00089|openflow|WARN:stream: send error: Bad file descriptor
00090|routingMR|ERR:OpenFlowMR::install_flow: flow-mod command to dpid
f7cae4000064 : error 9
00091|openflow|WARN:stream: receive error: Bad file descriptor
00092|nox|WARN:stream: disconnected (Bad file descriptor)
Datapath leave, f7:ca:e4:00:00:64
In the output above, what are the meaning of error 9 and 32. The
source code is simply as:
int ofc_ret = send_openflow_command(curr_dpid, &ofm->header, true);
if(ofc_ret) {
VLOG_ERR(lg, "OpenFlowMR::install_flow: flow-mod command to dpid
%s : error %d", curr_dpid.string().c_str(), ofc_ret);
}
Many thanks.
