Hi Experts,
I have a configured Netflow in an ASR router, but it doesn't export flow data as expected.
Router#sh flow monitor FLOW-MONITOR-1
Flow Monitor FLOW-MONITOR-1:
Description: User defined
Flow Record: IPV4_1
Flow Exporter: EXPORTER-2 (inactive)
EXPORTER-1 (inactive)
Cache:
Type: normal (Platform cache)
Status: allocated
Size: 200000 entries
Inactive Timeout: 15 secs
Active Timeout: 1800 secs
Update Timeout: 1800 secs
Synchronized Timeout: 600 secs
Trans end aging: off

Here is the relevant config:
Router#sh run flow monitor
Current configuration:
!
flow monitor Flow-FMM
exporter Flow-EM
cache timeout active 60
!
!
flow monitor FLOW-MONITOR-1
exporter EXPORTER-2
exporter EXPORTER-1
record IPV4_1
!
Router#sh run flow exporter
Current configuration:
!
flow exporter Flow-EM

I'm Facing the same issue with IOS XE Software, Version 03.17.00.S.

I am experiencing the same issue on my ASR.
But my config looks like this:
flow record NetFlowRecord
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
collect counter bytes
collect counter packets
flow exporter Solarwinds
destination 10.XXX.XXX.XXX
transport udp 2055
source Port-channel1
export-protocol netflow-v5
flow monitor NetFlow
exporter Solarwinds
record NetFlowRecord
#sh flow monitor NetFlow
Flow Monitor NetFlow:
Description: User defined
Flow Record: NetFlowRecord
Flow Exporter: Solarwinds (inactive)
Cache:
Type: normal (Platform cache)
Status: allocated
Size: 200000 entries
Inactive Timeout: 15 secs
Active Timeout: 1800 secs
Update Timeout: 1800 secs

I was able to fix this after I applied the flow monitor to particular interface to monitor the traffic (inbound/outbound). Eg. configuration below on a couple of switch ports.
interface GigabitEthernet1/0/1
switchport access vlan xxx
switchport mode access
switchport nonegotiate
switchport port-security maximum 10
switchport port-security aging time 5
switchport port-security aging type inactivity
switchport port-security
ip flow monitor PRTG input
spanning-tree portfast
!
PRTG is the name of the flow monitor.
Thoughts?

ip address xxx.xxx.xxx.xxx 255.255.255.252
no ip redirects
no ip unreachables
no ip proxy-arp
ip flow monitor NetFlow-monitor input
ip flow monitor NetFlow-monitor output
ip access-group 110 in
negotiation auto
no ipv6 redirects
no ipv6 unreachables
end
As you can see, I have the monitor enabled for both directions and I am still seeing the exporter as "Inactive". Makes no sense really.
Running IOX-XE version 3.17.03.S

Hi
After i changed the configuration to V9,it woks correct.
flow exporter EXPORTER-2
export-protocol netflow-v9

I cannot add the following to an interface or to the vlans which is why I believe mine shows to be inactive.
3750X-06(config)#inter g1/0/1
3750X-06(config-if)#ip flow monitor NETFLOW-MONITOR sampler NETFLOW-SAMPLER input
% Flow Monitor: 'NETFLOW-MONITOR' could not be added.
3750X-06#sh flow monit
Flow Monitor NETFLOW-MONITOR:
Description: NETFLOW-MONITOR
Flow Record: NETFLOW-RECORD
Flow Exporter: NETFLOW-EXPORTER (inactive)
Cache:
Type: normal
Status: not allocated
Size: 128 entries / 0 bytes
Cache:
Type: normal (Platform cache)
Status: not allocated
Size: Unknown
Why can't I add IP monitor commands? Is it the switch that is the problem? I am using a 3750-X.

I am having the same issue with Cat3750-X not be able to add ip flow monitor xxxxx on the interfaces.
08-16-2022 08:04 AM
I too am having the same issue? Any ideas? Software version problem?
RK10-SW1(config-if)#ip flow monitor MONITOR_IN input
% Flow Monitor: 'MONITOR_IN' could not be added.

Hello,
post the output of 'sh ver' so we can see what router model and IOS version you have...
