Set the LANsurveyor application options by selecting Options from the Tools menu. All options set in the Options Dialog box are saved with the application and used for alerts, reports, map node access, authentication, logging, and other general application preferences.
Network Options
Enter network timeouts, authentication, SMTP email settings, and SIP UDP socket settings via the Network tab. Timeouts are used when querying map objects or creating new maps. Network Timeouts can be changed on a map-by-map basis using the Mapping Speed slider. Authentication is required for accessing node information and reporting. Click the lock icon 
to show or hide your SNMP community string.
SMTP options are required for email alerts and include SMTP Authentication. The Voice-over-IP SIP UDP Socket number can also be set to match your VoIP environment, and you can specify a syslog host to receive LANsurveyor logging information.
In addition to the LANsurveyor Session Log, LANsurveyor can maintain a more detailed log in an external text file. The Logging options set which events are recorded and can help pinpoint application errors when working with Neon Software technical support.
Note labels are useful for adding descriptive text for reports. If you customize node labels, the text you enter here replaces "User Note #" in your reports that include Responder client data.
Don't show Neon Responder authentication alerts
Responder clients without passwords are automatically detected, and you are presented with the option to update the Responder with the password stored in the Network tab of the Options Dialog box. If you do not want to see this alert, select this option.
Don't show scheduling wizards
Reports and management operations give you the option to schedule those operations at a later time and date. If you would rather not encounter the scheduling portion of the report and management wizards, select this option.
Search private IP address ranges
Some organizations do not route private IP address ranges (e.g., 192.168.x and 10.x). However, many organizations assign these IP address ranges with DHCP servers and wish to map those nodes. If you would like to ignore private IP address ranges, uncheck this option.
Use switch port index rather than network interface name
Some switches have more descriptive switch port index names than network interface names. If you primarily use Cisco equipment, keep this item checked.
Use synchronous reverse-DNS lookups
Due to an anomaly in Windows networking, asynchronous reverse-DNS lookups can cause LANsurveyor to abort. Unchecking this option is not recommended.
Map switch/hub ports
Mapping switch/hub ports can show important information about how your network is physically connected. However, discovering those connections takes more time when drawing maps. You can set LANsurveyor to ignore switch/hub port connections by unchecking this option.
Redraw map when new nodes are discovered
When new nodes are discovered either using Rescan Map or Continuous Scan, LANsurveyor will automatically redraw your map, optimizing the network diagram layout. If you customize your map by moving nodes around and would like to preserve your customizations, uncheck this option.
Use Cisco VLAN Community String indexing
If your network equipment uses long port or interface names, you can truncate the map labels automatically to the number of characters you specify.
LANsurveyor works with third-party applications including Symantec's NetRecon, Microsoft's Baseline Security Analyzer, SSH clients, Qualys' QualysGuard, and syslog servers to increase your network security. Set options for those applications in this dialog box.
LANsurveyor uses lines (or edges) to connect nodes. If a node has SNMP enabled and the interface speed can be determined, you can specify the color and line thickness of those edges based on the maximum interface speed.
These Repository options are covered in the Reports section of this manual in the Repository chapter.
Your maps might have thousands of nodes, so LANsurveyor makes it easy to view your maps at different levels. Routers and network segments are Level 1 objects. Switches are Level 2 objects. Everything else is Level 3. If there are more than the specified number of Level 2 objects, routers and network segments (Level 1) will be displayed by default. Likewise, if there are more than the specified number of Level 3 objects, only Level 1 and Level 2 objects will be displayed.
You may also Filter which Level 3 objects are displayed.
Any LANsurveyor documents selected for AutoOpen are automatically opened when LANsurveyor is launched either manually or when LANsurveyor is run as a service.
If maps are specified, only those maps are used for Continuous Scan and Repository collection.
