Feature overview
1
Auto negotiation
Auto negotiation enables the access point to automatically exchange information about data
transmission speed and duplex capabilities. Auto negotiation is helpful when using the access
point in an environment where different devices are connected and disconnected on a regular
basis. For information on configuring the auto negotiation feature, see
“Configuring the LAN
interface” on page 99 or “Configuring WAN settings” on page 111.
Adaptive AP
An adaptive AP (AAP) is an access point that can adopt like an access port (L3). The management
of an AAP is conducted by a switch, once the access point connects to a A Brocade Mobility
RFS7000-GR Controller and receives its AAP configuration.
An AAP provides:
• local 802.11 traffic termination
• local encryption/decryption
• local traffic bridging
• the tunneling of centralized traffic to the wireless switch
For a information overview of the adaptive AP feature as well as how to configure it, refer to
“Adaptive AP” on page 545.
Rogue AP enhancements
The access point can scan for rogues over all channels on both of the access point’s 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 195.
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 211.
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.
