Layer 2

The wireless configuration of the network can be examined using the iwconfig eth0 command. We get MAC layer information such as

1. ESSID
   • olpc-mesh : Indicates a mesh with or without internet connectivity
2. Mode
   • Managed : It is an Access Point(AP) configuration
   • Ad-hoc : It is a mesh configuration(no infrastracture)
3. Frequency
   • 2.412 : Channel 1
   • 2.437 : Channel 6
   • 2.462 : Channel 11
   • Channels 1,6, 11 can be used to join a Link-local mesh
   • Channels 1, 6, 11 can also be a Schoolserver mesh (ch 1 is almost always on at OLPC offices)
   • At OLPC offices, '802.11 Media lab' AP operates on Channels 6 and 11
4. Cell/AP Mac
   • Access Point : The AP's MAC
   • Cell : A virtual 02:xx:xx:... MAC address assigned by the some mesh points. It indicates mesh configuration
