Statistics about source AS, destination AS, and peer ASs in version 5 or version 9 format.
•
• Statistics about BGP next hop only in version 9 format.
To configure the NetStream data export format:
Step
1. Enter system view.
2. (Optional.) Configure
the NetStream data
export format, and
specify whether to
record AS and BGP next
hop information.
A NetStream entry for a flow records the source IP address and destination IP address, and two AS
numbers for each IP address. You can choose to configure the AS numbers to be exported as the source
AS and destination AS:
• origin-as—Exports statistics of the source AS originating the route for the source address and the
destination AS for the destination address.
peer-as—Exports statistics of the peer ASs for the source and destination address.
•
For example, as shown in
reaches AS 24. NetStream is enabled on the device in AS 22.
If the origin-as keyword is specified, this command exports statistics of AS 20 (the source AS) and
•
AS 24 (the destination AS).
If the peer-as keyword is specified, this command exports statistics of AS 21 (the source AS) and AS
•
23 (the destination AS).

AS 21 is recorded as the source AS, and

Include origin-as in the command.
AS 20 is recorded as the source AS and
AS 24 as the destination AS.
