Manage Engine Netflow Analyser

Hello Community,

Hello Experts,

I'm evaluating Manage Engine's Netflow Analyzer. However, I'm not able to see the routers interface.

I have configured the router with the following Netflow Configurations:

show flow monitor
Flow Monitor FlowMonitor1:
  Description:       User defined
  Flow Record:       FlowRecord1TopT
  Flow Exporter:     NETFLOW-TO-ME
    Type:              normal

    Size:              32768 entries / 2097276 bytes
    Inactive Timeout:  15 secs
    Active Timeout:    86520 secs
    Update Timeout:    1800 secs

Can you tell me why I can't see the device?

Are the two devices able to ping one another. Is there a network device that is in between the Neflow Exporter and the Netflow Analyzer that perhaps has an ACL configured that is blocking/denying this traffic for UDP port 9995.

Using ping with the source keyword and "traceroute" will help you in identifying where the communication is failing at.

Hope this helps

Thanks for responding. The devices are indeed able to ping each other. No Acls blocking traffic
Since the two devices are able to ping one another and there are no ACL's blocking this traffic what type of host is running the netflow analyzer software? If this is a Windows PC you will need to modify the windows Firewall to allow port 9995 through the firewall.
