If you set an uplink selection policy of Follow global preference for example - tcp any to any : port xx yy. Then it would go back to the uplink selection of global preferences & go via whatever Primary uplink is set or load balance it if this option is enabled.
Now, for example i dont have an uplink selection policy of Follow global preference tcp any to any port xx yy it would still go via Primary uplink or load balance it.
Am i a fool keeping this policy for an year or does it really has some use ?
