Hi,
I tried to install two action buckets with fast fail over types. Though
the entries are installed properly, the packets are not flowing. I think
that the weight,atch_port or watch_group may be wrong..I didn't understand
the values set for these fields clearly..what does these fields denote.
Please clarify
