configuration utility, and includes the following topics:

This section describes how to navigate the AP configuration utility.
Browsers have the following restrictions:
•If you are using Internet Explorer 6, you cannot directly use an IPv6 address
to access the AP. You can, however, use the DNS (Domain Name System)
server to create a domain name that contains the IPv6 address, and then
use that domain name in the address bar in place of the IPv6 address.
•To use Internet Explorer 8, open a browser window and configure the
following settings:
Click 7RROV!,QWHUQHW2SWLRQV and then select the 6HFXULW\ tab. Select
/RFDO,QWUDQHW and click 6LWHV. Click $GYDQFHG and then click $GG. Add the
intranet address of the AP (http://<ip-address>) to the local intranet zone.
The IP address can also be specified as the subnet IP address, so that all
addresses in the subnet are added to the local intranet zone.
•If you have multiple IPv6 interfaces on your management station, use the
IPv6 global address instead of IPv6 link local address to access the AP from
your browser.

IEEE 802.11 authentication and association status, which is present no
matter which type of security the client uses to connect to the AP. This
status does not show IEEE 802.1X authentication or association status.
The following are some points to keep in mind with regard to this field:
-If the AP security mode is None or Static WEP, the authentication and
association status of clients showing on the Client Associations tab will
be in line with what is expected; that is, if a client shows as authenticated
to the AP, it will be able to transmit and receive data. (This is because
Static WEP uses only IEEE 802.11 authentication.)
-If the AP uses IEEE 802.1X or WPA security, however, it is possible for a
client association to show on this tab as authenticated (via the IEEE
802.11 security) but actually not be authenticated to the AP via the
second layer of security.
•)URP6WDWLRQ7R6WDWLRQ—For the From Station, the following counters

The TSPEC Client Associations page provides information about the TSPEC
client data transmitted and received by this access point. The tables on this page
show voice and video packets transmitted and received by the association, along
with status information.
This page shows a real-time display of the transmit and receive statistics for the
TSPEC clients. All transmit and receive statistics shown are totals since the client
association started.
A TSPEC is a traffic specification that is sent from a QoS-capable wireless client to
an AP requesting a certain amount of network access for the traffic stream (TS) it
represents. A traffic stream is a collection of data packets identified by the
wireless client as belonging to a particular user priority. An example of a voice

conference feed from a corporate server.
