Managed Switch Port Mapping Tool Overview
The Managed Switch Port Mapping Tool is an application designed
to 'map' or discover the devices attached to a network switch's ports. It does
this by accessing switch internal information using Simple
Network Management Protocol (SNMP) over the network. The end
user must provide SNMP access credentials unique to each
switch in order to access the switch. Device discovery
depends on the extent of the SNMP implementation and
permissions to access required MIBs in the switch.
can be manually mapped one at a time or in groups using
Switch mapping can be done from the GUI interface or through command line
parameters on a scheduled basis using Windows Task Scheduler. The results of a switch mapping are automatically
saved into an SQLite database for later retrieval or analysis.
They can also be saved to XML text files for independent
analysis through other programs like spreadsheets.
Many additional parameters are retrieved showing the current state of the
switch and devices connected to it.
The Managed Switch Port Mapping tool is designed for Windows XP or newer and will
also operate in Virtual Machines like Parallels or Fusion on

To see detailed information about the parameters or data retrieved
from the switch, go to the next tab above.
Information or data retrieved from the switch
This is a list of default columns and the
corresponding data you will typically see for each switch port.
Not all switches will report everything shown in this list.
- Interface description, 3 columns: ifDescr,
ifAlias or custom
- Interface name (ifName)
- Interface type (ethernet, gigabit ethernet,
tunnel, virtual, loopback etc.)
- VLAN (depending on the switch
we can even report multiple VLAN assignments per port)
- Port Status (up, down or other)
- Port Speed (10Mbps, 100Mbps, 1Gbps etc.)
- Port Duplex mode (full, half, auto,
FDx, HDx etc.)
- MAC addresses of devices attached
- IPv4 addresses and hostnames of
those devices if available**
- Attached device interface manufacturer
- helps identify devices.
- LLDP (Link Layer Discovery Protocol)
- shows connection information between devices attached
to the port like switches and routers.
- CDP (Cisco Discovery Protocol) - shows
connection information between devices attached to the port
like switches and routers.
- Last Change Time column shows the elapsed
time since a port status was changed from up to down or
from down to up. Useful in determining how long a device
has been online or offline.
Addition optional switch data:
- Port input and output byte counts
- Port bandwidth utilization
- Spanning Tree Protocol (STP) information
including port status and root information
- From OLD-CISCO-MIB: CRC Errors, Framing
Errors, Overrun Errors, Packet Ignored Errors, Packet Abort
Errors, Output Collision Errors, Input Queue Full Dropped
- From RMON-MIB: Dropped Packets, CRC
Errors, Undersized Packets, Oversized Packets, Fragmented
Packets, Jabber Packets, Collision Errors
Basic switch properties:
- Switch name
- Switch uptime
- Location field
- Switch administrator contact name
Additional product specific switch information:
The additional information retrieved varies
significantly depending on manufacturer and model.
- Switch model number
- Switch serial number
- Software version (ie. IOS x.x, JUNOS,
- Firmware version
- Hardware revision
- Asset number
**Obtaining IPv4 addresses.
Managed switches usually operate at layer
2 which means they keep track of the MAC addresses attached
to their ports and report the information in Bridge-Mib and/or
qBridge-mib. The IP addresses are not kept in the switch's port
forwarding tables. When we retrieve the data from the switch,
we have to find the IP address that matches the list of device
MAC addresses for each port. We do this by searching ARP tables
from various devices. We provide two user defined methods of
retrieving ARP tables from other SNMP enabled devices such as
a server or router. Ping Sweep prefills your computer's local
ARP table with local network segment IP/MAC addresses. You
can also import a static list of MAC/IP address combinations
in Database Manager.
How the Switch Mapping Results are presented
When a switch mapping is completed, you
are presented with a Summary Report in your web browser. The
slideshow on the Overview tab shows an example Summary Report.
This report can be saved or printed as desired. It provides
a high level analysis of what was retrieved from the switch.
The app shows the Switch Mapping results in a spreadsheet style
grid (see the slideshow on the Overview tab). The columns of
the grid can be reordered and made visible or invisible to suit
the your needs. The results are searchable using one of the
many selections available from the right-click popup menu.
You can export the results as either tab delimited text or XML
suitable for opening directly by Microsoft Excel or OpenOffice.
The imported spreadsheet retains the look and presentation of
the results in the program.
Will it work with your switches?
Try it. That's the best way to find
out. Download and
our free trial. You will need to know your switch IPv4 address
and SNMP v1/v2c community name or SNMPv3 access credentials.
You will also need to be sure SNMP is enabled on the switch
and you have permissions to access the internal MIBs (your computer
IP may need to be on an Access Control List (ACL) or part of
a specific 'view').
Please review list long
list of switches that we and others have tested with our software.
This list includes compatibility of switches reported to us
The list also shows switches that do not work with this software.
- Manufacturer Independent
- capable of mapping many different brands and models of
SNMP managed switches.
- A Time Saver - saves technicians time mapping
out the physical layout of your network by helping identify
network devices attached to the physical switch ports.
- Shows Downstream Devices - shows multiple downstream
devices connected by hubs or other switches.
- Shows Switch Parameters - device MAC Address,
device IP address**, VLAN assignment, port status, speed,
duplex, byte counts in/out, bandwidth usage, connected device
interface manufacturer, Spanning Tree Protocol status with
root information and more.
- Identifies Virtual Operating Systems - reports
switch ports with devices running virtual operating systems.
- Easy-to-understand Results Presentation - spreadsheet
format results can be printed in color and searched for
- Export results to spreadsheet schema XML or tab delimited
text files - the XML file can be directly opened by
Microsoft Excel XP/2003/2007 or OpenOffice Calc.
- Results can be saved in XML and reloaded for later
- Work with Multiple Switches Easily - switch and
device 'configurations' including IP addresses and community
names are automatically saved in a database and can be loaded
for rapid change between different switches. No need to
re-enter switch information.
- Integrates into NetScanTools Pro Optional Tools menu.
Operates standalone or as a tool launched from within NetScanTools
**device IP addresses require retrieval of
ARP tables from one or more devices with knowledge of the network.
We cannot guarantee finding an IP address for every MAC address.
