Hi All,
I am trying to set up queues on port 'eth0' of switch 's3' using the
following code:
from ryu.cfg import CONF
from ryu.lib.ovs import bridge
config_path = "tcp:10.0.0.103:6640"
ovsdb_bridge= bridge.OVSBridge(CONF, datapath.id, config_path)
ovsdb_bridge.set_qos("s3-eth0",
queues=[{'min-rate': '10000', 'max-rate': '100000'},{'min-rate':
'500000'}],
max_rate="100000000")
switch 's3' address is '10.0.0.103' and my controller is at address
'10.0.0.1'. I am using Ryu(4.18) and OpenFlow 1.3 I am also opening the
manager for the port eth0 at the switch 's3'
using " ovs-vsctl set-manager ptcp:6640 " in xterm
I am getting the following error:
Connection refused
