Which two match fields does Cisco NX-OS use as the defaults when you create a flow record?
(Choose two.)
Answer: A and B.
Cisco NX-OS enables the following match fields as the defaults when you create a flow record:
• match interface input
• match interface output
• match flow direction
Cisco Nx-OS defaults to User Datagram Protocol (UDP) port 9995 for NetFlow Data Export.
To configure NetFlow on a switch you perform the following steps:
• Define a flow record by specifying key and non-key fields of interest.
• Define one or many flow exporters by specifying export format, protocol, destination and other parameters.
• Define a flow monitor based on the above flow record and flow exporter(s).
• Apply the flow monitor to an interface with a sampling method specified.
NetFlow export packets use the IP address that is assigned to the source interface. If the source interface does not have an IP address assigned to it, the flow exporter will be inactive.
