Issue:

Unable to model Windows server in Spectrum. A sniffer trace run on the SpectroSERVER system shows the SNMP leaving Spectrum but no response from the device. It also shows the ICMP leaving Spectrum and the device responding.

Cause:

The most likely cause is a firewall blocking SNMP traffic

Resolution:
  • Check any firewalls between the SpectroSERVER system and the device you are attempting to model. Ensure the firewalls are not blocking SNMP traffic
  • Check the firewall rules on the Windows system to ensure they are not blocking SNMP traffic
