Configuring NetFlow
The refresh rate defines the maximum delay a new or restarted NetFlow collector
would experience until it learns the format of the data records being forwarded
(from the template referenced by the data records). Refresh rates affect NetFlow
collectors during their start up when they must ignore incoming data flow reports
until the required template is received.
Setting the appropriate refresh rate for your Matrix system must be determined,
since the default settings of a 20 packet refresh rate and a 30 minute timeout may
not be optimal for your environment. For example, a switch processing an
extremely slow flow rate of, say, 20 packets per half hour, would refresh the
templates only every half hour using the default settings, while a switch sending
300 flow report packets per second would refresh the templates 15 times per
second.
Enterasys recommends that you configure your Matrix system so it does not refresh
templates more often than once per second.
Use the show netflow config command
configured values.
Example
This example shows how to set the Version 9 template packet refresh rate to 50 packets and the
timeout value to 45 minutes
