Q.
How is enterprise wireless mesh managed?
A.
Enterprise Wireless Mesh is an integral part of the Unified Wireless Network. As with all
components of the Unified Wireless Network, mesh APs obtain configuration, security
policies, and RF parameters from Cisco wireless LAN controllers. Wireless LAN controllers
are in turn managed by the Cisco Wireless Control System (WCS). Cisco WCS provides an
easy-to-use, intuitive graphical user interface (GUI) that displays key network statistics,
including traffic statistics, link characteristics, and client information.
Q.
Which software release supports enterprise wireless mesh?
A.
The enterprise wireless mesh feature will be introduced in mesh release 2.0. Mesh release 2.0
is based on 4.1 MR1. Note that enterprise wireless mesh will not be supported on the mainline
release train until the mesh train merges back into the mainline 12+ months in the future.
Q.
Does the mesh release train support future mainline release features?
A.
The mesh release train is targeted for the acceleration of mesh technology and enhancements
to the mesh features. For a limited time, development on the mesh release train will occur in
parallel to the mainline release train; new mainline features will not be available on the mesh
release train. Once the mesh enhancements are complete, the mesh release train will merge
back into the mainline, providing both advanced wireless mesh technology and the various
innovations introduced in the mainline.
Q.
Will clients experience service interruption roaming between indoor and outdoor
environments?
A.
The advanced mesh technology is applicable to the outdoor as well as the indoor access
points. This ensures seamless mobility across indoor and outdoor environments and the users
experience no service interruption as they roam freely from indoor to outdoor environments.
Mesh Technical Questions
Q.
How does mesh networking work?
A.
At the heart of Cisco mesh networks is a patent pending protocol called Adaptive Wireless
Path Protocol (AWPP). The intelligent wireless routing of AWPP allows the access points to
discover each other automatically and select the best path for maximizing system capacity
and minimizing latency. Access points continuously communicate with other nodes, evaluating
the potential of each link to improve performance. If a link is degraded, the access point will
determine whether a better path exists, and will route traffic through a more optimal node. A
mesh network eliminates the need to wire every access point in the network, making it easier
and more efficient to extend the reach of the network.
Q.
Can the root APs also provide wireless connectivity to clients?
A.
Yes, root APs can also provide wireless connectivity for clients.
Q.
What happens when an existing route is no longer available due to the failure of a mesh
AP?
A.
Through Cisco AWPP, each mesh AP maintains a list of neighbor AP information including
SNR, ease value and bridge-group name. If a mesh AP loses connectivity with its parent, it will
use the neighbor information to determine the best parent AP to connect with.
