WDS and number of APs

Question

Is it possible to have multiple WDS servers in one subnet?
I was wondering if entering an IP address at the option "Specified Discovery" for all APs could make it possible to have APs register themselves to a specified WDS AP in one subnet? My client will go well above the max of 60 WDS APs per server.

Hi Bas,
Here is an excerpt from a Cisco document that addresses this issue:
How many infrastructure access points (APs) can a single WDS manage?
A single WDS AP can support a maximum of 60 infrastructure APs when the radio interface is disabled. The number drops to 30 if the AP that acts as the WDS AP also accepts client associations.
Can I set up more than 60 access points (APs) in a WDS that uses AP-based WDS?
Do not use more than 60 APs on one WDS master. You can run into CPU utilization problems with more than 60 APs. You can have multiple WDS masters, but they need to be on different subnets. An example is the use of:
One WDS master and 30 APs on 10.10.10.10
Another WDS master and 30 APs on 10.10.20.20
In this case, the issue is that you cannot fast roam between WDS domains.
