If more than one neighbor, then uses Least Cost Algorithm Channels : RAP uses configured channel or defaults to 161 MAP follows the channel of the RAP on the backhaul Data rates: RAP MAP will use configured data rates. 18 Mbps is the default data rate for 11a and recommended Temporary Secure Connection: AP will send default shared key MAC address to the Controller. Controller will send back Shared Secret Key and disconnect Secure LWAPP connection: AP will store the Shared Secret Key and use it for LWAPP connection Presentation_ID ? 2006 Cisco Systems, Inc.

Cisco Confidential 34 1510 AP 属性 Role – Indicates whether the Mesh AP is a RAP or MAP Default Shared Key – Used to get a Secret Shared Key Secret Shared Key – Password that lets the APs communicate securely before an LWAPP session can be established with the Controller Bridge Group Name – Logically groups APs. Allows a customer to have neighboring networks and not have them interfere with each other Backhaul Interface – The wireless protocol used to communicate with other APs Channel – The specific channel over the backhaul interface that the Bridged APs use to communicate to each other Path – This is the easiest path with least cost back to the Controller Data Rate – The rate that the data is shared between APs. This is fixed for the whole network Five of these properties must match for APs to communicate Presentation_ID ? 2006 Cisco Systems, Inc. All rights reserved.
