Troubleshooting Your Map

Top Previous Next

LANsurveyor maps include icons to represent your end-nodes and SNMP-enabled devices. If the map icons are generic "IP" computer icons, one or more of the following could be true:

•	your devices do not support SNMP

•	SNMP is not enabled on your devices

•	you do not have the correct SNMP community string (password) for your SNMP devices

•	your SNMP devices' access control lists haven't been configured to accept requests from the LANsurveyor computer

•	a firewall is preventing access to your devices (SNMP, ICMP, SIP, etc. requests are blocked)

Refer to Appendix C, SNMP Checklist, for troubleshooting details. Also, consider including more autodiscovery options in the Create a New Network Map dialog box, adding Responder clients, and checking to make sure you have the correct SIP UDP port specified in the Network Options dialog box.

Finally, try building your map using a slower, more accurate mapping speed.
