Diagnostic Tools
Issue 6, January 2011 87
The following screen shows how the display would look when there are three APs
configured with an SSID that matches that of the Wireless IP Telephone. The first has a
signal strength of –28 dBm, is configured on channel 2, with a beacon interval of 100ms.
The second has a signal strength of –48 dBm, is configured on channel 6, with a beacon
interval of 200ms. The third has a signal strength of –56 dBm, is configured on channel
11 with a beacon interval of 100ms.
a b 7 b c 8 - 2 8 0 2 1 0 0
2 a e 5 7 8 - 4 8 0 6 2 0 0
2 a e 5 9 6 - 5 6 1 1 1 0 0

When the Any SSID mode is selected, the summary display contains the first six
characters of the APs SSID instead of the beacon interval as in the example below.
a b 7 b - 2 8 0 2 A L P H A
2 a e 5 - 4 8 0 6 W S M T E S
2 a e 5 - 5 6 1 1 v o i c e

In the Detl (detail) mode the display would appear as follows. The Left/Right arrow keys
will move between AP indices.
i : b b b b s n c h b c n

Where:
• i – Index of selected AP (value will be from 0 to 3 inclusive)
• bbbb – The last three octets of the BSSID for a discovered AP.
• sn – Signal strength in –dBm
• ch – Channel
• bcn – Beacon interval
• eeeeeeeeeee – SSID (Up to first 11 characters)
• DGHI – Standards supported i.e. 802.11d, 802.11g, etc. in addition to 802.11a and
802.11b.
• rrrrrrrr – Rates supported. Basic rates will have a “b” following the rate.
• + – more rates are supported than those displayed
• Q:XP
X is a Hexadecimal representation of the access categories configured with admission
control mandatory (ACM). Bit3 = voice, Bit2 = video, Bit1 = background, Bit0 = best
effort. For example, if an AP advertises voice and video as ACM then X=c. If all the
ACs are set as ACM then X=f. If AP does not have WMM support, this character space
will be blank.
P is displayed when the AP advertises WMM-PS. If the AP does not advertise WMM-
PS then this character space will be blank.
