Hi,
To use fast fail over feature, we have to add more than one buckets. Do
we have to assign the weights for these two buckets as zero. If not what
should be the value. Further what does watch_port and watch_group
represent. In case of fast fail over group type what should be the value
for these two fields. Please clarify
Thanks and Regards,
Padma V
