Command History
Usage Guidelines Flexible NetFlow uses key and nonkey fields just as original NetFlow does to create and populate flows
in a cache. In Flexible NetFlow, a combination of key and nonkey fields is called a record. Original
NetFlow and Flexible NetFlow both use the values in key fields in IP datagrams, such as the IP source
or destination address and the source or destination transport protocol port, as the criteria for
determining when a new flow must be created in the cache while network traffic is being monitored. A
flow is defined as a stream of packets between a given source and a given destination. New flows are
created whenever NetFlow analyzes a packet that has a unique value in one of the key fields.
Once you enter the flow record configuration mode, the prompt changes to the following:
switch(config-flow-record)#
Within the flow record configuration mode, the following keywords and arguments are available to
configure the flow record:
• collect—Specifies a nonkey field. See the collect command for additional information.
• description description—Provides a description for this flow record; you use a maximum of 63
characters.
• exit—Exits from the current configuration mode.
• match—Specifies a key field. See the match command for additional information.
• no—Negates a command or sets its defaults.
record-name Name of the flow record that is created or modified.
