Colasoft MAC Scanner 1.1
If you need to determine the
Media Access
Control (MAC) addresses on a
LAN using a Windows system,
Colasoft provides a tool,
MAC Scanner,
which you can use to scan all IP addresses in a subnet to obtain a list
of the MAC, aka hardware addresses, associated with those IP addresses.
The
results
can be exported to a text or Comma Separated Value (CSV) file.

Dell PowerConnect 3024 - Finding MAC Addresses
To determine the
Media Access Control (MAC) addresses of devices connected to a Dell
PowerConnect 3024 switch, take the following steps:
- Select Address Manager from the main menu.
PowerConnect 3024
Main Menu
a. System Manager
b. Port Manager
c. Address Manager
d. Spanning Tree
e. VLAN and CoS Setup
f. Port Trunking
g. Port Mirroring
h. SNMP Management
i. Multimedia Support
j. Statistics
k. Save Configuration
Hit to configure Static Address Table or Address Aging Time
<Ctrl-L> Refresh <Ctrl-W> Save
- Select Dynamic Addresses from the Address Manager menu.
PowerConnect 3024
Address Manager
a. Static Addresses
b. Dynamic Addresses
c. Address Aging
d. Static Multicast Groups Administration
e. Static Multicast Groups Membership
Hit <Enter> to view Dynamic Addresses
<ESC> Back <Ctrl-L> Refresh <Ctrl-W> Save
You will then see the MAC addresses that have been seen by the switch for each
port. Ports with no device attached will not be listed. If nothing is listed
for a port at the time you check, though, that does not necessarily mean that
no device is attached to that port, only that no activity has been seen on
that port recently. A system could be attached to the port, but turned off, or
may be on, but has not communicated with another device over the network
recently.
If the switch is seeing multiple MAC addresses on a port, as it would
if there is another switch or hub plugged into the port, which itself
has multiple systems plugged into it, it will show all of the MAC addresses. In
the example below, 5 addreses are listed for port 6 and 4 addresses
are listed for port 16. There is another switch connected to port 6
and a hub connected to port 16.

If you see a MAC address which you don't recognize, you can lookup up the
manufacturer of the network adapter associated with that address at
Vendor/Ethernet MAC Address
Lookup and Search, which may help you identify what type of device
is connected on the port showing that MAC address. For instance, when I look
up 00:09:6b:19:38:a5, I see the vendor listed as
"IBM Corporation". When I look up 00:17:a4:26:88:d5, I see
"Global Data Services (may now be Hewlett-Packard, HP)" listed and, in
this case, the device is an HP K5400 printer.
