Cisco IOS XE Software, Version 16.06.04
Cisco IOS Software [Everest], Catalyst L3 Switch Software (CAT3K_CAA-UNIVERSALK9-M), Version 16.6.4, RELEASE SOFTWARE (f
c3)
Hey all. Ive looked through a lot of posts, but didnt see any that helped me. Ive configured records, monitor, exporter and applied to interface on a 3850. But when I check monitor statistics, its 0
r3#show flow monitor tfb statistics
Cache type: Normal (Platform cache)
Cache size: 10000
Current entries: 0
Flows added: 0
Flows aged: 0
------
Here is the config, which I copied from a 3650 where its working.
------
flow record tfb
match ipv4 tos
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
match interface input
collect interface output
collect counter bytes long
collect counter packets long
collect timestamp absolute first
collect timestamp absolute last
!
!
flow exporter whatsup01
destination 10.5.200.68
transport udp 9999
!
!
flow monitor tfb
exporter whatsup01
cache timeout active 60
record tfb
...
interface TenGigabitEthernet1/0/12
description uplink-r1
switchport mode trunk
ip flow monitor tfb input
spanning-tree portfast disable
ip nbar protocol-discovery
Any idea what Ive done wrong?

here is the config for 3850 ( but your post also mentioned 3650 - not sure what version)
here is 3850 config
flow record tfb
match ipv4 version
match ipv4 tos
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
match interface input
match flow direction
collect transport tcp flags
collect interface output
collect counter bytes long
collect counter packets long
collect timestamp absolute first
collect timestamp absolute last
collect counter bytes layer2 long

flow exporter whatsup01
destination 10.5.200.68
source VlanXX
transport udp 9999
!

flow monitor tfbmonitor <--change to monitor
exporter whatsup01
cache timeout active 60
record tfb
...
interface TenGigabitEthernet1/0/12 <--- i was not sure it support Trunk port never tested
description uplink-r1
switchport mode trunk
ip flow monitor tfb input
spanning-tree portfast disable
ip nbar protocol-discovery
Any L3 / L2 intercace works
interface interface XX
ip flow monitor tfbmonitor input <<--- <--change to monitor
Test and Advise.

Can you post show version. Full config (removing any confidential to look).
Do you have QoS Enabled ?

As suggested my other post, can you move the config from Trunk port to different L2 or L3 port and test and advise.
