Appendix F Performing a Site Survey
Using Passive Mode
Link Speed
In passive mode, the site survey tool monitors transmitted
network traffic, and the data rate reflects the rate at which the
packets are being transmitted.
The Link Speed histogram provides a visual interpretation of the
current rate at which your client adapter is transmitting packets.
Differences in link speed are indicated by the following colors:
green (fastest), yellow (middle of the range), and red (slowest).
Value:
1, 2, 5.5, or 11 Mbps (2.4-GHz client adapters);
6, 9, 12, 18, 24, 36, 48, or 54 Mbps (5-GHz client
adapters)
Overall Link Quality
The client adapter’s ability to communicate with the access point.
Value:
Not Associated, Poor, Fair, Good, or Excellent
Note
This setting appears for 2.4-GHz client adapters (but only
if you selected signal strength to be displayed as a
percentage) and for 5-GHz client adapters. See the
“Specifying Signal Strength Units” section on page F-3
for information.
Signal to Noise Ratio
(2.4-GHz client adapters)
The difference between the signal strength and the noise level.
The higher the value, the better the client adapter’s ability to
communicate with the access point.
Range:
0 to 90 dB
Note
This setting appears only for 2.4-GHz client adapters and
only if you selected signal strength to be displayed in
dBm. See the
“Specifying Signal Strength Units” section
on page F-3
for information.
Associated Access Point
The access point to which your client adapter is associated. It is
shown only if the client adapter is in infrastructure mode, the
access point was configured with a name, and Aironet Extensions
are enabled (on access points running Cisco IOS Release
12.2(4)JA or greater).
Access Point IP Address
The IP address of the access point to which your client adapter is
associated. It is shown only if the client adapter is in
infrastructure mode, the access point was configured with an IP
address, and Aironet Extensions are enabled (on access points
running Cisco IOS Release 12.2(4)JA or greater).
Note
If Aironet Extensions are disabled, the IP address of the
associated access point is shown as 0.0.0.0.
