NTM 2.2.1 Release Notes
Updated March 15, 2018
These release notes provide additional guidance for SolarWinds Network Topology Mapper version 2.2.1.
These new features are available in NTM versions 2.2.x:
NTM version 2.2.1
- Endpoints Summary:
As a way of keeping maps from being overcrowded by clusters, an Endpoints Summary window is for a network device that switches or routes traffic to servers, VMWare or Hyper-V hosts, printers, or other devices that are part of your edge network.
- CDP-generated Nodes:
Undefined nodes that are created from CDP data appear in maps with their system name and any available description.
NTM version 2.2
- Multiple Maps from One Scan:
From a Discovery Wizard scan, you can create multiple maps, which update automatically with scheduled updates to the scan
- Credential Management:
Discovery Wizard stores credentials, allowing you to activate or deactivate based on the network segment(s) you are mapping
Discovery of aggregates (PAgP and LACP protocols, or manually configured)
- Do No Scan List:
Define subnets or IP ranges that the Discovery Wizard will not contact
- New Icons:
A set of node icons, parallel link icons with indications of aggregation, and support for importing icons.
- Usability Improvements:
For example: clicking a Neighbors icon on a node reveals all directly connected nodes or the subnet/IP arrange to which the selected node is connected; and any overlapping but distinct links are indicated with arches.
NTM version 2.2.1
- Fixed issue with valid VIM credentials failing credential test.
- Fixed issue with not detecting the first IP address in a subnet.
NTM version 2.2
- Fixed the behavior of rescan detecting existing nodes as new nodes
- Whitespace in Switching from Layered or Orthogonal View.
- White space appears where excluded nodes would be.
- Fixes restrictions with map layouts (through movable text, parallel connections, link aggregation indicators, and selectable topology configurations).
- Fixes limitations with node icons (both by expanding options and flexibility of the NTM set out of the box, and through custom import function).
- Fixes limitation in iconically representing nodes by model and vendor.
- Resolves inability to export to Visio and edit NTM maps (with Visio stencils).
- Resolves inability to customize NTM node icons.
- Fixes an issue with a print operation crashing NTM.
- Fixes an issue with NTM not mapping switch ports accurately.
- Fixes a limitation in using different credentials for discovering different parts of network.
- Fixes limitation in providing data on aggregated links (etherchannels).
- Fixes an issue with reporting bandwidth for Allied Telesys switches.
- Fixes am issue with the NTM jumbling node names.
- Fixes issue with symbols in the SNMP community string blocking network discovery.
- Fixes an issue that causes NTM to crash after rescanning a network.
- If you try to install NTM on Windows Server 2003 that doesn't have Windows Imaging Components, the installer fails with the error "0x800713ec - Asia".

- On Windows 2003 SP1, selecting the repair option in the Setup wizard sometimes causes the installer to quit unexpectedly.
- If you have Microsoft SQL CE 3.5 SP1 or SP2 installed, then you must remove it before running the NTM installer or the installer may fail.
- If the 'license.dat' file has been deleted, then NTM does not work and the repair option does not fix the issue.
- Router Etherchannels are detected that do not in fact exist.
- Orthogonal map layout function works unreliably with large maps.
- Nodes from Shortcuts cannot be dropped onto the map after manual connections have been created. Drag/drop from Discovered Notes remains unaffected.
- A map created in NTM v.1.0.1 that includes aggregated links (EtherChannels) does not display oval icons that indicate aggregated links even after being rescanned in NTM 2.2. The work-around is to uninstall NTM 1.0.1 before installing NTM 2.2, changing an upgrade to an installation operation.
- Corruption of WMI service on a customer machine causes NTM to shutdown.
- Missing L2 connections between switches.
- Nodes identified using CDP/LLDP may display ASCII characters.
- This behaviour is seen if nodes identified connecting to a SNMP device have unknown or empty device ID information.
- If you run a discovery for an NTM map that contains virtual machines for which you have already entered credentials, then discovery will run twice.
- Network Discovery also runs twice when when NTM exports map data with VIM credentials into Network Atlas
- Maps containing larger than 1000 nodes may introduce a slight delay while toggling between filters and map layouts.
- If your devices do not support CDP/LLDP or Bridge table data, then NTM cannot display Layer 2 connections between the devices. More likely these devices will show up as orphan nodes.
- De-duplication does not work for connections, which were reported by CDP and LLDP.
- If you run discovery for an NTM map that contains virtual machines that you've already entered credentials for, the discovery will run twice.
- It takes a long time to open maps larger than 1000 nodes. NTM may appear unresponsive, but the map will open eventually.
- The integrated Remote Desktop function won't work on Windows Server 2003 64-bit unless you have applied the Microsoft Hotfix and append %winDir%\Sysnative to your %path% variable.
- If the NTM certificate is deleted or modified by another program, none of the scheduled discoveries will work until you repair the certificate and then reschedule all the discovery jobs.
- NTM can't display L2 connections from devices that do not provide bridge table data. If you are missing L2 connections, this is the likely cause.
- NTM does not import unmanaged nodes and edges from Network Atlas maps.
- Network Segment Nodes do not show up by default in maps created in NTM 1.0.
- Help links default to the top of the file when displayed in Internet Explorer v8. The workaround is to use a later version of the IE browser.
