supported on the Cisco Aironet 1510 Access Point, is being extended to the 1522 and 1524
access point platforms in Release 4.1.192.22M.
High-Speed Roaming on Cisco IOS Software Mesh Access Points
The Cisco Aironet 1522 and 1524 Access Points support clients certified by the Cisco Compatible
Extensions program, Version 4, to roam between mesh nodes at up to 70 MPH. For instance, a
customer with a Cisco 3200 Series router operating as a wireless workgroup bridge can provide
persistent network connectivity to devices within the vehicle while roaming at speeds up to 70
MPH.
Access Point Authentication Using an External AAA Server
Access points attempting to join the network can now be authenticated using any authentication,
authorization, and accounting (AAA) server, whether it is the AAA server native to the Cisco WLAN
controllers or a separate AAA server. Customers can simplify their end node authentication design,
providing an added layer of security for mesh access points joining the wireless network.
Universal Access for Cisco Aironet 1522 Access Point
The Cisco Aironet dual-band 1522 access point can provide access services to clients on the
same radio that is being used for backhaul. This will allow customers to expand access to Wi-Fi
clients operating in the 4.9- or 5.8-GHz band. This feature, previously supported on the Cisco
Aironet 1510 access points, is being extended to the 1522 access point platform in Release
4.1.192.22M. Note that this feature is not yet available on the Cisco Aironet 1524 access point.
Multicast Containment
For devices that are attached to the Ethernet port of the 1522 and 1524 access points and that
source multicast traffic, this traffic can be contained to the Ethernet port of the root access point.
This prevents traffic from being sent unnecessarily to mesh nodes that do not have any multicast
group subscribers. It’s useful, for instance, for video surveillance traffic being sent to multiple video
content servers on the wired network.
