Routing Engine-Based Sampling to Multiple Flow Servers

Routing Engine-based sampling supports up to eight flow servers for both version 5 and version 8 configurations. The total number of collectors is limited to eight, regardless of how many are configured for version 5 or version 8. When you configure sampling, the export packets are replicated to all collectors configured to receive them. If two collectors are configured to receive version 5 records, both collectors will receive records for a specified flow.

The following configuration example allows replication of export packets to two collectors.

forwarding-options {sampling {input {family inet {rate 1;}}output {cflowd 10.10.3.2 {port 2055;version 5;source-address 192.168.164.119;}cflowd 172.17.20.62 {port 2055;version 5;source-address 192.168.164.119;}}}}
