V.5.6
Mesh Secure Authentication of Equals (SAE)
In 802.11s mesh mode, no mesh node has a special identification role, all
nodes are considered equal in privileges. When SAE is used, all nodes must
have a preset common key. Each time a node comes in reach of another
node in the same mesh, it will verify that the peer node knows the key. The
encryption uses the WPA2 protocols suite (AES/CCMP).
The password key can be from 8 to 63 printable ASCII characters. The same
password must remain stored in all the mesh nodes.
V.6
Wired to wireless bridging in infrastructure mode
V.6.1
The problem
As outlined in section
V.2.1
, in the 802.11 standard
an infrastructure client
is supposed to be a single unit with a single MAC address.
The AP
forwards data to/from the client, from/to other clients or wired devices. In
this respect the AP is similar to an Ethernet switch.
Bridging several devices with a single wireless client
To allow the AP to forward data, each frame includes a source MAC and a
destination MAC.
Standard infrastructure data frames (3 addresses)
