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.
Select the desired option:
Network
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 SolarWinds 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.
The Miscellaneous options are described below.
Don't show LANsurveyor 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.
Search 1.x IP address ranges
By default, LANsurveyor discovery ignores all 1.x IP address ranges. Check this option to have LANsurveyor discover 1.x IP address ranges.
Use switch port index rather than network interface name
Specify whether to use the switch port index or the switch port description for the port label. Examples are shown below:
If Use switch port index rather than network interface name is not checked:
| • | Cisco or other vendor non-stackable switch has label: FastEthernet 14 |
| • | Cisco stackable switch has label: FastEthernet 1/14 |
If Use switch port index rather than network interface name is checked:
| • | Cisco or other vendor non-stackable switch has label: Port 12 |
| • | Cisco stackable switch has label: Port 1/12 |
If you are seeing a problem with the port mapping on your switches, or if you primarily use Cisco equipment, keep this item checked.
Note: The port number displayed represents an internal index value and not a physical label on the device.
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.
Discover Layer 2 connectivity for VLAN IDs greater than 1000
By default, LANsurveyor discovers Layer 2 connectivity for all VLANs whose IDs are less than 1000, since VLAN IDs above 999 are virtual. For those customers who set the VLAN IDs of their switches to values larger than 1000, selecting this option causes LANsurveyor to discover all VLANs regardless of their ID.
Hide SNMP Community Strings
Select this option if you want LANsurveyor to always keep the SNMP community strings confidential so that unauthorized personnel cannot view them on the display.
Don't show Getting Started screen on start
Select this option if you do not want LANsurveyor to display the Getting Started screen at startup with its options for learning how to use LANsurveyor.
Redraw the map on levels change
Select this option if you want LANsurveyor to redraw the map when levels are changed, recomputing node positions as needed. This option is selected by default. Uncheck this option if you simply want to hide nodes that do not belong to the new level, preserving their location, and redisplaying them when changing back to the previous level.
Truncate edge labels to nn characters
Enter the maximum character length for labels on connection lines in the map. Note that this length should be a number between 8 and 100 to avoid truncation that makes the labels difficult to read.
LANsurveyor works with third-party applications including SSH clients 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.
The Repository options are described in the Repository section of this manual.
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.
