Usage Guidelines
A flow record requires at least one key field before it can be used in a flow monitor. The key fields distinguish
flows, with each flow having a unique set of values for the key fields. The key fields are defined using the
match
command.
The match flow direction command captures the direction of the flow as a key field. This feature is most
useful when a single flow monitor is configured for input and output flows. It can be used to find and eliminate
flows that are being monitored twice, once on input and once on output. This command can help to match up
pairs of flows in the exported data when the two flows are flowing in opposite directions.
Examples
The following example configures the direction the flow was monitored in as a key field:
Device(config)# flow record FLOW-RECORD-1
Device(config-flow-record)# match flow direction
