Hi,
I want to set more than one bfd parameters from the controller. ie) i have
to execute the following command
sudo ovs-vsctl set interface s6-eth1 bfd:enable=true bfd:min_rx=100
bfd:min_tx=100
if i use
cmd = ovs_vsctl.VSCtlCommand('set', ('Interface', 'eth2',
'bfd=enable=true', 'bfd=min_tx=100'',bfd=min_rx=100'))
then, only the last one is set(min_rx=100). other two are not set properly.
How to achieve this. Please clarify.
Thanks and Regards,
Padma V
