Modification

7.0(0)N1(1)

This command was introduced.

Usage Guidelines

Flow exporters export the data in the flow monitor cache to a remote system, such as a server running NetFlow collector, for analysis and storage. Flow exporters are created as separate entities in the configuration. Flow exporters are assigned to flow monitors to provide data export capability for the flow monitors. You can create several flow exporters and assign them to one or more flow monitors to provide several export destinations. You can create one flow exporter and apply it to several flow monitors.

Once you enter the flow exporter configuration mode, the prompt changes to the following: 


switch(config-flow-exporter)#

Within the flow exporter configuration mode, you can enter the version 9 keywords. Once you enter the version 9 keywords, the prompt changes to the following: 


switch(config-flow-exporter-version-9)#

When entering the no form of this command, the seconds argument is optional.

This command does not require a license.

Examples

This example shows how to specify the name of the flow exporter that is created or modified. 


switch(config)# flow exporter flow-export-test
switch(config-flow-exporter)# version 9
switch(config-flow-exporter-version-9)#

This example shows how to specify the version 9 exporter statistics option templates and data: 


switch(config)# flow exporter flow-export-test
switch(config-flow-exporter)# version 9
switch(config-flow-exporter-version-9)# exporter-stats

This example shows how to specify the version 9 interface table option templates and data:
