Q.
What happens when a root AP loses Ethernet connectivity?
A.
The RAP maintains a list of neighbor AP information including SNR, ease value and bridge-
group name. If Ethernet connectivity is lost, the root AP becomes a mesh AP and uses this
information to select the best parent AP to connect with.
Q.
What is the recommended number of hops for an enterprise wireless mesh
deployment?
A.
Depending on the application and coverage density, the recommended number of hops
should not be more than 4. For optimized performance, 2 or fewer hops are recommended.
Q.
Is Hybrid Remote Edge Access Point supported with enterprise wireless mesh?
A.
No.
Q.
Is voice supported for enterprise wireless mesh?
A.
The Aironet access points are WMM capable and QoS is supported on the local 2.4 GHz
access and for the 5 GHz backhaul. Although Call Admission Control (CAC) is supported
between the clients and the AP, full voice support requires CAC on the backhaul link to ensure
end to end voice quality. Therefore, voice over enterprise wireless mesh is not currently
supported. However, testing has shown that it takes several voice calls to saturate the mesh
network.
Q.
Does location work effectively over enterprise wireless mesh?
A.
While location functionality on an indoor AP with a wireless backhaul link should work no
differently from an indoor AP with a wired backhaul link, it has not been fully tested and is not
yet fully supported. Support for this capability is planned in a future software release. For
further information, please contact your Cisco representative.
Q.
What security features are available with enterprise wireless mesh?
A.
All of the security features available with the Cisco Unified Wireless Network are available
when using the enterprise wireless mesh feature, including 802.11i / WPA2, 802.1X
authentication, and hardware-based AES encryption. Security is also provided over the
wireless backhaul links using the X.509 digital certificates to authenticate the access point to
the wireless mesh and using hardware-based AES encryption for data privacy.
