NOTE
The pre-shared key must be 8 to 63 characters long.
The WDS Altitude APs use this pre-shared key to establish a WDS link between them.
NOTE
Changing the pre-shared key after the WDS is deployed can be a lengthy process. For more information, see
"Changing the pre-shared key in WDS WM-AD" on page 229.
9 Assign the roles, preferred parents and backup parents to the Altitude APs.
NOTE
The roles - parent, child, and both - are assigned to the radios of the Altitude APs. An Altitude AP may connect
to its parent Altitude AP and children Altitude APs on the same radio, or on different radios. Similarly, an
Altitude AP can have two children operating on two different radios.
The radio channel on which the child Altitude AP operates is determined by the parent Altitude AP.
If the Altitude AP will be serving both as parent and child, you must select both as its role.
To configure the WDS as illustrated in Figure 19 with a single WDS WM-AD, you must assign the
roles, preferred parents and backup parents to the Altitude APs according to the following table:
NOTE
Since the Root Altitude APs - Ardal, Arthur, Athens and Auberon - are the highest entities in the tree structure, they
do not have parents. Therefore, the Preferred Parent and Backup Parent drop-down lists of the Root Altitude APs do
not display any Altitude AP. You must leave these two fields blank.
