Cisco Aironet Software Requires Completion of Encryption Authorization Form
In order to access Cisco Aironet software from the Software Center on Cisco.com, you must now fill out
a form to receive authorization to download encrypted software. Registered Cisco.com users are required
to fill out the form only once, but public users must do so once each session, each time software is
downloaded. A form is automatically created for public users. The form for Registered Cisco.com users
is located at the following URL:

Reboot of Workgroup Bridges Required When Allowing More Than 20
With VxWorks firmware version 12.05, you can select no for the Classify Workgroup Bridges as
Network Infrastructure setting on the AP/Root Radio Advanced page to allow up to 20 workgroup
bridges to associate to the access point or bridge. After selecting no for this setting, you must reboot
workgroup bridges associated to the access point or bridge.

The ‘Reliable multicast messages from the access point to workgroup bridges’ setting limits reliable
delivery of multicast messages to approximately 20 Cisco Aironet Workgroup Bridges that are
associated to the access point. The default setting, disabled, reduces the reliability of multicast delivery
to allow more workgroup bridges to associate to the access point.

to allow more workgroup bridges to associate to the access point.
Access points and bridges normally treat workgroup bridges not as client devices but as infrastructure
devices, like access points or bridges. Treating a workgroup bridge as an infrastructure device means that
the access point reliably delivers multicast packets, including Address Resolution Protocol (ARP)
packets, to the workgroup bridge.
devices, like access points or bridges. Treating a workgroup bridge as an infrastructure device means that
the access point reliably delivers multicast packets, including Address Resolution Protocol (ARP)
packets, to the workgroup bridge.
The performance cost of reliable multicast delivery—duplication of each multicast packet sent to each
workgroup bridge—limits the number of infrastructure devices, including workgroup bridges, that can
associate to the access point. To increase beyond 20 the number of workgroup bridges that can maintain
a radio link to the access point, the access point must reduce the delivery reliability of multicast packets
to workgroup bridges. With reduced reliability, the access point cannot confirm whether multicast
packets reach the intended workgroup bridge, so workgroup bridges at the edge of the access point's
coverage area might lose IP connectivity. When you treat workgroup bridges as client devices, you
increase performance but reduce reliability.

Cisco Discovery Protocol Re-Enabled for Individual Interfaces on Reboot
The Cisco Discovery Protocol (CDP) feature is enabled by default, and CDP is enabled for each of the
access point’s or bridge’s individual interfaces by default. However, if you disable CDP for one of the
individual interfaces, the access point or bridge re-enables CDP for that interface when it reboots. If you
disable CDP completely, the access point or bridge does not re-enable CDP on reboot.
