Rogue AP enhancements
The access point now has the option to scan for rogues over all channels on both of the access
point’s 11a and 11bg radio bands. The switching of radio bands is based on a timer with no user
intervention required.
For information on configuring the access point for Rogue AP support, see “Configuring rogue AP
detection” on page 162.
Bandwidth management enhancements
Use the Bandwidth Management screen to control the network bandwidth allotted to individual
WLANs. Define a weighted scheme as needed when WLAN traffic supporting a specific network
segment becomes critical. Bandwidth management is configured on a per-WLAN basis. However, a
separate tab has been created for each access point radio. With this new segregated radio
approach, bandwidth management can be configured uniquely for individual WLANs on different
access point radios.
For information on configuring bandwidth management, see “Configuring bandwidth management
settings” on page 126.
Radius time-based authentication
An external server maintains a users and groups database used by the access point for access
permissions. Various kinds of access policies can be applied to each group. Individual groups can
be configured with their own time-based access policy. Each group’s policy has a user defined
interval defining the days and hours access is permitted. Authentication requests for users
belonging to the group are honored only during these defined hourly intervals.
For more information on defining access point access policies by group, see “Defining user access
permissions by group” on page 173.
QBSS support
Each access point radio can be configured to optionally allow the access point to communicate
channel usage data to associated devices and define the beacon interval used for channel
utilization transmissions. The QBSS load represents the percentage of time the channel is in use by
the access point and the access point’s station count. This information is very helpful in assessing
the access point’s overall load on a channel, its availability for additional device associations and
multi media traffic support.
For information on enabling QBSS and defining the channel utilization transmission interval, see
“Configuring the 802.11a or 802.11b/g radio” on page 121.
