• Statistics about source AS, destination AS, and peer ASs in version 5 or version 9 format.
• Statistics about BGP next hop in version 9 format only.
To configure the NetStream export format:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure the
NetStream data export
format, and specify
whether to record AS
and BGP next hop
information.
• ip netstream export version 5
[ origin-as | peer-as ]
• ip netstream export version 9
[ origin-as | peer-as ]
[ bgp-nexthop ]
By default:
• The NetStream traditional data
export uses the version 9 format.
• MPLS flow data is not exported.
• The peer AS numbers are exported
for the source and destination.
• The BGP next hop is not exported.
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 which 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 Figure 54 , a flow starts at AS 20, passes AS 21 through AS 23, and then
reaches AS 24. NetStream is enabled on the device in AS 22. If the origin-as keyword is specified, the
command exports statistics of AS 20 (the source AS) and AS 24 (the destination AS). If the peer-as
keyword is specified, the command exports statistics of AS 21 (the source AS) and AS 23 (the destination
AS).
Figure 54 Recorded AS information varies with different keyword configurations
AS 20 AS 21
AS 22
AS 23
Enable NetStream
Include origin-as in the command.
AS 20 is recorded as the source AS and
AS 24 as the destination AS.
AS 24
Include peer-as in the command.
AS 21 is recorded as the source AS, and
AS 23 as the destination AS.
