NetFlow Policy Page
Version The NetFlow version number, which defines the record format to be
used for flow. You can choose the blank entry to disable this option.
• 1—The original record format. No additional parameters are
required.
• 5—The most widely adopted format; includes Border Gateway
Protocol (BGP) autonomous system (AS) information and flow
sequence numbers.
If BGP is configured on your network, you can include either
origin or peer AS information in the NetFlow records. Choose
origin-as or peer-as from the AS Type drop-down list. You can
choose the blank entry to disable this option.
Check Enable BGP Nexthop to include BGP next hop information
in the flow caches. (Note that with version 5, this information is
visible in the caches, but it is not exported.)
• 9—The most-recent, template-based version; not yet fully
supported.
If BGP is configured on your network, you can include either
origin or peer AS information in the NetFlow records. Choose
origin-as or peer-as from the AS Type drop-down list. You can
choose the blank entry to disable this option.
Check Enable BGP Nexthop to include BGP next hop information
in the flow records.
Note AS information collection is resource intensive, especially for
origin-as. If you are not interested in monitoring peering
arrangements, disabling AS collection might improve
performance.
