To do… Use the command… Remarks
1. Enter system view.
system-view —
.ip netstream export version 5
[ origin-as | peer-as ]
2. Configure the version for
NetStream export
format, and specify
whether to record AS
and BGP next hop
information
ip netstream export version 9
[ origin-as | peer-as ] [ bgp-
nexthop ]
Optional.
By default, NetStream traditional data
export uses version 5; MPLS flow data
is not exported; the peer AS numbers
are exported for the source and
destination; the BGP next hop is not
exported.

For more information about an AS, see

IP Routing Configuration Guide
.
A NetStream entry for a flow records the source IP address and destination IP address, each with two AS
numbers. The source AS from which the flow originates and the peer AS from which the flow travels to the
NetStream-enabled device are for the source IP address; the destination AS to which the flow is destined
and the peer AS to which the NetStream-enabled device passes the flow are for the destination IP address.
To specify which AS numbers to be recorded for the source and destination IP addresses, include
keyword peer-as or origin-as. For example, as shown in Figure 74,
a flow starts from AS 20, passes AS
21 through AS 23, and reaches AS 24. NetStream is enabled on the device in AS 22. If keyword peer-as
is provided, the command records AS 21 as the source AS, and AS 23 as the destination AS. If keyword
origin-as is provided, the command records AS 20 as the source AS and AS 24 as the destination AS.
