[Ryu-devel] curr_speed and max_speed isnt correct

[Tahereh Yaghoubi]

​​

Hi ,


I'm getting OF_PORT information by using OFPDescStatsReply event. But for
all of ports, these values max_speed=0, curr_speed=10000000 are set while I
can receive EventOFPPortStatsReply in all ports correctly. Also I can ping
all of hosts. my app OFPPortDescStatsRequest code is:


req = parser.OFPPortDescStatsRequest(datapath, 0)

datapath.send_msg(req)


and I'm getting its reply as:

@set_ev_cls(ofp_event.EventOFPPortDescStatsReply, MAIN_DISPATCHER)
def port_desc_stats_reply_handler(self, ev):
ports = []
for p in ev.msg.body:
ports.append('port_no=%d hw_addr=%s name=%s config=0x%08x '
'state=0x%08x curr=0x%08x advertised=0x%08x '
'supported=0x%08x peer=0x%08x curr_speed=%d '
'max_speed=%d' %
(p.port_no, p.hw_addr,
p.name, p.config,
p.state, p.curr, p.advertised,
p.supported, p.peer, p.curr_speed,
p.max_speed))



I'm using ovs 2.7, openflow 13 and mininet.


Could you please say in which condition curr_speed and max_speed gets this
value?


Thanks in advanced

Hi, Tahereh

I reproduced your situation.
I inspected the EventOFPPortStatsReply packets from OVS by using wireshark,
apparently ovs always replies that its max_speed=0 and curr_speed=10000000,
regardless of whether pings are send or not.

Ryu seems to get EventOFPPortStatsReply correctly and I think the
problem is in OVS.
Could you ask to OVS team?

Thanks,
Fujimoto
