as the collect field in the flow record, then the output
interface is detected based on the destination address
in the switch. Hence, for the different flow monitors,
the following are required to be configured:

•
For ipv4 flow monitor, configure "match ip
destination address"
•
For ipv6 flow monitor, configure "match ipv6
destination address"
•
For datalink flow monitor, configure "match
datalink mac output"
The collect interface output field will return a value
of NULL when a flow gets created for any of the
following addresses:
•
L3 broadcast
•
L2 broadcast
•
L3 Multicast
•
L2 Multicast
•
