Technical Support, Problems and Solutions

We have many videos demonstrating how to use the software with different switches on this page.

Please review the Common Problems support page.

Look for your switch or similar switch model in our Switch Compatibility List. Even if your switch is not on the list, please try the switch and tell us what happens. This is a list of switches the application has been tested with.

Review the operating system and other requirements on this page.

Review the Getting Started Page.

This page explains methods for improving your mapping results.

Review the Upgrade Page. Warning: if you are moving from v1.x to v2.x, this is a one way upgrade - the software makes changes to the user database that cannot be reversed and it is not a free upgrade.

All changes since version 1.0 are on the Revision History Page. Press the F1 key to activate built-in help and review the Revision History in the help file.

It is easy. Instructions are on this page.

There are two ways to address this. Instructions are on this page.

This software was developed on Windows 10 x64.

Please visit this page for more on these switches including how to activate SNMP.

If your IOS is Version 15.0(1)EX3, the duplex mode information is not being reported correctly by the switch. The dot3StatsDuplexStatus always returns a value of '1' (unknown). The solution is to upgrade IOS. Please review this Cisco bug report.

Router/Server 1 or 2: No, it only reads out tables like the ARP table. You are not even allowed to enter SNMP 1 or 2c write community name.

Switch under examination: Yes, it is possible to change the MIB2 sysName, sysContact and sysLocation. You can also turn off a port. You must enter the 'write' privileges community name. The way to change sysName, sysContact and sysLocation is to map the switch, then right click and select Properties of this Switch. Then press Change Information in Switch, change the fields and press Change. If you have the correct privileges, it will change. Turning on and off a port is similar, map the switch, then click on a row corresponding to a port. Then right click and select Disable Selected Port. Be careful - especially turning off ports.

We have found that a standard Windows command prompt works best. Users have reported problems using it in Powershell. Note that if the software is started from the command line, the GUI shows and is required for operation.

This is due to the resolver watchdog timer hitting a limit that is found in left control panel/Global Settings/DNS Warning Time. This value used to be 120 seconds - the new default is 360 seconds as of v2.63. You should change it to a higher number if you see the timeout message.

The Managed Switch Port Mapping Tool supports SNMPv1, SNMPv2c, and SNMPv3. We strongly recommend using the software in SNMPv2c (or v1) mode first to verify that it actually maps your switch. SNMPv3 requires detailed settings that must exactly match on the switch and in the settings for this software.

We use the latest Webroot and MalwareBytes to check the installer and the installed executable files. We also submit each release to VirusTotal.com and the VirusTotal report is on the download page.

Please submit false positive reports to us here.

Why you see '?' and what you can do about it.
You have no hostnames and you do have IP addresses in the IP address column.
You have some hostnames but many IP addresses in the IP address column have '?' in the hostname column.
You have hostnames for IP addresses, but some hostnames are wrong.

Please download the latest version. This was fixed in 2.71.

This page explains why it is important to activate LLDP on your attached devices where possible.

Not usually. Why? routers and firewalls do not typically fully implement crucial aspects of Bridge MIB or qBridge MIB. You are welcome to try, but do not be surprised if you get error messages about missing mib support.

Right click in the results area after mapping a switch. Select "Remove rows marked 'I/F not present'". It may take a while if there are many of them.
