Good afternoon,
I've solved my previous problem (01-10-2020). It turns out '--columns=options'
is not an available option in the OVSDB library in Ryu and I was not aware of
that. I apolagize.
However, I think I've found a bug coming from vsctl.py, in /ryu/lib/ovs (but I
hope I'm wrong). I'm trying to do a simple task: list all ports of an OVS or
list all ports associated with a bridge. The following commands
were executed in the same order as shown and their outputs are below each one:
_______________________________________________________
c = vsctl.VSCtlCommand('list-br')
print(c)
>> "br0"
c = vsctl.VSCtlCommand('br-exists', "br0")
print(c)
>> [False]
c = vsctl.VSCtlCommand('list-ifaces', "br0")
print(c)
>> "no bridge named b"
________________________________________________________
Now, using only "ryu.lib.ovs.bridge":
_____________________________________________
result = br.get_port_name_list()
>> "no bridge named None"
result = br.get_port_name_list("br0")
>> get_port_name_list() takes 1 positional argument but 2 were given
_________________________________________________________
As anyone experienced this problem before? It's like the string of the name of
the bridge, "br0", never reaches as a whole to the function "find_bridge(self,
name, must_exist)" of vsctl.py.
It's important to note that when I print the "self.bridges" variable inside the
"find_bridge" function, a dictionary with a "br0" key is displayed.
Could the problem be the fact that I'm using openflow13?
Regards,
Inês
