The J-Flow v9 template is associated with the external flow collector. Specify the sampling rate and run set forwarding-options sampling input rate set forwarding-options sampling input run-length 0Ĭonfigure the external flow collector and its port address. Note: For more information about this example, refer to the Application Note.Ĭonfigure the J-Flow v9 template (as of now, only the IPv4 template is set services flow-monitoring version9 template ipv4-test ipv4-template The following procedure provides an example of the J-Flow configuration for version 9: Note: SRX Branch chassis clusters do not support the use of J-flow version 9.

The following procedure provides an example of the J-Flow configuration for versions 5 and 8 (this procedure should also work with NetFlow versions 5 and 8):Įnable sampling on one or more interfaces and specify the set interfaces ge-0/0/0 unit 0 family inet sampling set interfaces ge-0/0/0 unit 0 family inet sampling outputĬaution: Activation of flow collection can have a significant impact on the performance of the SRX Series device.
