The switch(MD_SAL|openflow:4/CPqD switch) is connected to the controller</p> <p>4. Run the command addMeter openflow:4 on osgi prompt</p> <p>5. The meter get added to the CPqD switch<br/> root@mininet-vm:/home/mininet# sudo dpctl tcp:127.0.0.1:6680 meter-config<br/> SENDING:<br/> stat_req{type="mconf", flags="0x0"</p> {meter_id= ffffffff"} <p> RECEIVED:<br/> stat_repl{type="mconf", flags="0x0", stats=[{meter= c"", flags="4", bands=[</p> {type = dscp_remark, rate="12", burst_size="5", prec_level="1"} <p>]}]}</p> <p>6.

I think we can close this bug.</p> <p>THanks<br/> Anil</p> <p>Hi Avishnoi/Praveen,</p> <p>The bug is an OVS issue and not the controller, since the meter multipart request/reply messages are working fine with CPqD switch but not for OVS.</p> <p>So, I am closing it.</p> Development External issue ID 386 External issue URL Rank 0|i02ytz:
