catalyst 9000 - netflow - collect routing AS NOT working

Hello

I am currently using FNF with C6500 router with BGP activated on it.
on C6500 I can collect BGP AS info using Netflow flow record "collect routing source as 4-octet" command

We have migrated our C6500 towards C9500; I configured FNF on it

the command "collect routing source as 4-octet"  is STILL accepted 
but when configured , my collector does NOT recover NF record form my C9500.
when I removed this command, I correctly receive the NF record on my collector (without any collector modification).

So my questions are

- is this command supported on C9500 ios7.3.3 (or later) ?

- is the reply the same on C9500(NOT X) and C9300 ?

- is there so any possibility to colelct as in teh AS path of the BGP route ?

 

regards

llo
thanks for reply but
match (key field) for routing allows only the following options so NO AS

-LSW-C02(config-flow-record)#match routing ?
vrf VRF routing attributes

-LSW-C02(config-flow-record)#match routing vrf ?
input VRF ID for incoming packet

-LSW-C02(config-flow-record)#match routing ?
vrf VRF routing attributes

-LSW-C02(config-flow-record)#match routing vrf ?
input VRF ID for incoming packet

-LSW-C02(config-flow-record)#match routing vrf input ?
<cr> <cr>
-LSW-C02(config-flow-record)#

furthermore, for me , I think that "AS" is a NON key field parameters and shall be find into collect command
do under the collect routing part, but there no more possibility to type collect routing AS

ILM-LSW-C02(config-flow-record)#collect routing ?
multicast Multicast routing attributes
next-hop Information regarding the next hop

ILM-LSW-C02(config-flow-record)#collect routing

so it seems to me it is NOT anymore possible to collect BSG receive AS for the flow we receive on a Cat9000 equipment.
> Did someone else arrive to teh same conclusion ??

regards 

 

Let me check again 

Thanks for waiting
