Description

Specify the flow export rate of monitored packets in kpps. If you have multiple line cards of different types running on the same router, the flow-export-rate will be applied to each card. However, the rate applied to the PFEs on the card will vary in accordance with the number of PFEs that are on the card.

On the MX Series, the actual flow export rate might be less than the configured flow-export-rate. In addition, the maximum flow export rate for an FPC or MPC module cannot exceed the configured flow-export-rate, regardless of how many PICs or MICs are on the module.

Options

rate

Flow export rate of monitored packets in kpps (from 1 through 400).

  • Default: 1 kpps (applies to all PFEs on the FPC)

Note:

The maximum rate per PFE is 100 kpps for LU, 800 kpps for XL/EA, so for an FPC with four LU PFEs (such as AS cards) you can set a maximum flow-export-rate of 400. For an FPC with two LU PFEs (such as the MPC2), the maximum flow-export-rate is 200. For an FPC with one LU PFE (such as the MPC5), the maximum is 100. The Junos CLI accepts as valid any value within the range of 1 to 3200, but when applied the value might trigger an error message such as “The configured flow export rate is higher than supported value/chip” in the Junos message log.
