Determining a Wireless Unit’s Full Hexadecimal Address<br />
If you do not know the full hexadecimal address of a wireless unit (either<br />
an access point or a mobile unit) in your network, you should first check<br />
the unit. Often, the address is written on the equipment itself.<br />
If this does not work, you can use the Host Table or Expert displays to<br />
discover the address. However, because most displays substitute textual<br />
manufacturer IDs for the first three bytes of a hexadecimal MAC address<br />
(that is, a hexadecimal address of 0020d8014060 would usually be<br />
identified in displays as Netwav014060), you need to know where to<br />
look in Sniffer <strong>Portable</strong> <strong>Professional</strong> displays to find the entire address in<br />
hexadecimal.<br />
To determine a wireless unit’s full hexadecimal address:<br />
1 Start capturing from the network containing the unit whose<br />
address you want to determine. Alternatively, you can open a trace<br />
file captured from that network.<br />
2 In the Expert display, examine the Station Function column in the<br />
Summary pane at the Wireless layer. In this column, locate an<br />
entry for either an Access Point or a Mobile Unit. Highlight this<br />
entry.<br />
The Detail pane automatically updates to show statistics for the<br />
entry selected in the Summary pane.<br />
3 In the Detail pane, scroll down to the Wireless Address field. This<br />
field shows the entire hexadecimal address of the selected unit. A<br />
textual manufacturer’s ID is not substituted for the first portion of<br />
the address.<br />
4 Repeat this procedure for each access point on the network whose<br />
full hexadecimal address you want to determine.<br />
Importing and Exporting Known Addresses<br />
Sniffer <strong>Portable</strong> <strong>Professional</strong> also provides export and import capabilities<br />
for the known address lists in the Tools > Expert Options > 802.11<br />
Options tab.<br />
You can export the contents of either the Known Access Points or the<br />
Known Mobile Units list using the corresponding Export button in the<br />
802.11 Options tab. Exported files are saved in comma-separated<br />
values (CSV) format. The exported file consists of a heading row with<br />
the IP Address and MAC Address column headings followed by<br />
multiple data rows in the format IP Address,MAC Address. For example,<br />
a small exported CSV file might appear:<br />
IP Address,MAC Address<br />
