Hi Huiy,
The error message indicates different engine type is expected by
the Netflow collector. FYI, we are not supporting Netflow collector even
thoughour cflowd implementation has functioned well with previous versions
of Netflow.
Since you are using a newer version of Netflow and we don't have
Cisco's new design specification, we cannot anticipate and react to the
Netflow version every time that Cisco puts out a new release.
I think that you may want to request that Cisco modify their software
to accept different engine types. I believe they are rejecting the Juniper
records because they do not come from a Cisco router.
I would recommend that you search on the cisco web site
and find out additional information about the following fields.
20 engine_type Type of flow switching engine
21 engine_id ID number of the flow switching engine
22 aggregation Aggregation method being used
23 agg_version Version of the aggregation export
Find out what the acceptable values are.
Also, have you considered using a publically available and open
version of cflowd collector? This will likely help you avoid these
types of problems in the future.
Finally, you can request an enhancement to the Junos code
to allow you to configure the engine-type. However, this request
should be made through your local Juniper Sales Team.
Do you know who your local Juniper Systems Engineer is?
Thanks,
Bob O'Hara

Hello,everyone.
I'd like to use Netflow Collector3.0(2.0) to collect RouterAS information
from Juniper routers.
The Version 8 Header Format Cisco is using is as follows:
0每1 version NetFlow export format version number
2每3 count Number of flows exported in this flow frame
4每7 SysUptime Current time in milliseconds since the export device booted
8每11 unix_secs Current seconds since 0000 UTC 1970
12每15 unix_nsecs Residual nanoseconds since 0000 UTC 1970
16每19 flow_sequence Sequence counter of total flows seen
20 engine_type Type of flow switching engine
21 engine_id ID number of the flow switching engine
22 aggregation Aggregation method being used
23 agg_version Version of the aggregation export
24每27 reserved Unused (zero) bytes
Cisco set agg_version to 2 now,but Juniper set agg_version to 0.
And the other field is the same.When Netflow Collector 3.0 receive
V8 data from Juniper rou! ters,it says "error engine_type" and discard
the data. Anyone knows how to solve this problem?
Thanks a lot!
