Meaning of the output values in "ovs-ofctl dump-ports"

Solution In Progress - Updated -


  • Would you have any good material that explains the meaning of the parameters in the "ovs-ofctl dump-ports" output?

  • For instance, what does the following in the output means:

   - errs 
   - frame
   - over 
   - crc  
   - coll 
  • ovs-ofctl dump-ports br-ex returns something similar to this:
[root@overcloud-controller-0 ~]# ovs-ofctl dump-ports br-ex
