Local mesh
Local mesh link types
7-3
Note Depending on the radio regulations of some countries, DFS channels are only available on the
802.11aband, which is the preferred band for local mesh backhaul. If more than one node
detects radar simultaneously and must switch channels, each node does not necessarily
switch to the same channel, and the network might never reconverge. To avoid this problem,
local mesh detects a change in channel and provides a means to reconnect on other channels
by scanning on multiple channels. See Operating channel on page 7-6.
Local mesh link types
Two types of local mesh links are supported: static and dynamic.
Static local mesh links
Static local mesh links can be used to create a fixed wireless connection between two APs,
creating a wireless bridge between the networks connected to the two APs. For example, in
the following scenario, a static wireless link is created between AP 1 and AP 2. Each AP is
connected to a separate physical network, but both networks are on the same IP subnet
(192.168.5.0). Traffic is bridged across the wireless link, allowing User A to communicate
with User B.
Terminology
The following terms are used in this guide when discussing the static local mesh feature.
Configuration guidelines
The following guidelines apply when you create a static local mesh link between two or more
APs:
All radios used to establish the link must be set to the same operating frequency and
channel. This means that on the Wireless > Radio page under Channel, you cannot select
Automatic.
Term Definition
Local The AP that you are currently configuring to support a static link.
Remote The AP that to which the static link will connect.
Link The wireless connection between a local and remote AP.
