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 Routing Engine-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-inactive-timeout 30;flow-active-timeout 60;interface sp-4/0/0 {source-address 10.10.3.4;}}}}
