Flexible Netflow not working on 4500X-16

[maissiat]

Dear All, 

I would like to enable FNF on a 4500X-16 switches in VSS mode. I followed the guide from Cisco , but nothing is send to my collector (Prime 3.0) 

Context : 

Cisco 4500X-16 in VSS, IP Base license, IOS-XE 03.07.02.E  , remote site 

Collector : Headquarter 

WAN = VPN Tunnel 100Mb - Allow ANY 

My config on the 4500X 

flow record r1
match datalink dot1q priority
match ipv4 tos
match ipv4 ttl
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
collect interface input
collect counter bytes
collect counter packets
collect timestamp sys-uptime first
collect timestamp sys-uptime last
!
!
flow exporter e1
destination "IP Collector"
source Vlan96
transport udp 9991
!
!
flow monitor m1
exporter e1
cache timeout inactive 30
cache timeout active 60
cache entries 1000
record r1

Interface tengi1/1/4  

ip flow monitor m1 input

It looks that no flows are collected 

if I ran the sh flow monitor m1 statistics  cmd,  I see nothing , all fields are at zero. 

. Any idea is warmly welcome, because I have a similar setup also on a remote site but  on 3750X and works fine. 

Thanks

Dear Shaunak,

First thank you for your reply, secondly. It is a 4500X-16 10G Switch. running the IOS-XE 3.07 version.

Hi Maissiat,

Is the te1/1/4 a layer 3 routed interface or a layer 2 trunk or layer 2 interface?

Thanks,

Shaunak

Hi Maissiat,

Did you find out what the issue was?

I have the exact same issue with a 4500-X VSS and I was wondering if you had figured it out.

Thank you,

Sebastian

Hi Sebastian,

Upgrading to an higher version of IOS-XE resolved the issue. We are now running version 03.08.00.E

Best Regards
