Good evening, I'm working on a project where I'm required to have the information on the remote IP address of a Vxlan Interface configured on OVS.
Since I cannot obtain that information (at least not to my knowledge) in simple_switch_13.py (the switch I am using), I was following the documentation in https://ryu.readthedocs.io/en/latest/library_ovsdb.html#ryu.lib.ovs.vsctl.VSCtlCommand and trying to reproduce the ovs-vsctl command: "ovs-vsctl --columns=options,name,type list Interface", without luck. First of all, I managed to run the following piece of code successfully: ______________________________________________________________________ from ryu.lib.ovs import vsctl OVSDB_ADDR = 'tcp:172.16.1.10:6640' ovs_vsctl = vsctl.VSCtl(OVSDB_ADDR) command2 = vsctl.VSCtlCommand('list', ('Interface', 'vxlan0.2')) ovs_vsctl.run_command([command2]) print(command2.result[0].name) >> "vxlan0.2" ______________________________________________________________________ Then, I tried to reproduce the ovs-vsctl command I wanted, which in the OVS outputs to: options : {remote_ip="172.16.1.40"} name : "vxlan0.4" type : vxlan options : {remote_ip="172.16.1.30"} name : "vxlan0.3" type : vxlan This is one of my many attempts: _______________________________________________________________________________ from ryu.lib.ovs import vsctl OVSDB_ADDR = 'tcp:172.16.1.10:6640' ovs_vsctl = vsctl.VSCtl(OVSDB_ADDR) command1 = vsctl.VSCtlCommand(args=('Interface'), command='list', options=('--columns=options')) ovs_vsctl.run_command([command1].result[0].options) ________________________________________________________________________________ However, either the "options" argument gives an error, or result[0] does not have the attribute I want.... My attempts have been endless. I've also been searching through vsctl.py code to try and find a solution for the structure, but I simply cannot understand how to formulate the command. Please help me on this, I've been stuck for a long time...
