It used to work. Please look over my configs.

Below is a partial config that I am using for a cisco 3850 L3 switch. We are trying to monitor network traffic to a Solarwinds server. Does anyone notice anything out of the ordinary?

I have only recently hired on at this establishment and this is something that hasn't worked in a few years. So, I'm trying to eliminate things to better get an idea of what the hold up is.

Re: It used to work. Please look over my configs.

Correction

we are only wanting to monitor the last 2 interfaces that I mentioned:

interface GigabitEthernet3/0/21
  switchport access vlan 90
  switchport mode access
  switchport voice vlan 10
  ip flow monitor NetFlow-to-Orion-Input input
  ip flow monitor NetFlow-to-Orion-Output output
  auto qos trust
  spanning-tree portfast
  service-policy input AutoQos-4.0-Trust-Cos-Input-Policy
  service-policy output AutoQos-4.0-Output-Policy

interface GigabitEthernet5/0/38

  description **Uplink to Sophos Firewall**

  switchport access vlan 250

  switchport mode access

  ip flow monitor NetFlow-to-Orion-Input input

  ip flow monitor NetFlow-to-Orion-Output output

  spanning-tree portfast
