Replicating Version 9 Flow Aggregation to Multiple Flow Servers

With this feature, you can configure up to eight flow servers to receive packets for a version 9 flow monitoring template. Once a flow server is configured to receive this data, it will also receive the following periodic version 9 flow monitoring updates:

Options data
Template definition

With RE-based sampling, if multiple collectors are configured with version 8 export format, all of them must use the same aggregation-type

The option and template definition refresh period is configured on a per-template basis at the [edit services flow-monitoring] hierarchy level.

The following configuration example allows replication of version 9 export packets to two flow servers.



forwarding-options {


sampling {


input {


family inet {
rate 1;
}


}




output {


flow-server 10.10.3.2 {
port 2055;


version9 {


template {
ipv4;
}


}


}




flow-server 172.17.20.62 {
port 2055;


version9 {


template {
ipv4;
}


}


}

flow-active-timeout 60;


interface sp-4/0/0 {

}


}
