Hi,
Problem solved by this code:
from ryu.lib import dpid as dpid_lib
dp_str = dpid_lib.dpid_to_str(datapath.id)
print(dp_str)
sw = [dp_str[i:i+4] for i in range(0, len(dp_str), 4)]
print('kazkas:%s',sw)
if sw[1] == '1458': #vendor (product) mac address prefix
print('HP')
table_id=100
Regards,
Vilius.

Subject: [Ryu-devel] detect SW vendor
Hi,
I found that OVS and HP use different flow tables for setting flow rules.
It's possible to determinate switch vendor? I was using mininet OVS. And
what waitress do? I tried this code:
@set_ev_cls(ofp_event.EventOFPSwitchFeatures, CONFIG_DISPATCHER) def
miss_flow (self, ev):
datapath = ev.msg.datapath
desc = ofctl_v1_3.get_desc_stats(datapath)
print('desc=%s', desc.hw_desc)
In console get this error:
CONSUMES EventOFPEchoRequest
CONSUMES EventOFPPortDescStatsReply
CONSUMES EventOFPSwitchFeatures
connected socket:<eventlet.greenio.GreenSocket object at 0xb678572c>
address:('127.0.0.1', 48609) hello ev
