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.
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.
As I found out yesterday, specified discovery is not a workaround for having more than one WDS master.
I had about 40 APs configured to communicate to the a WDS master and was trying to add a second WDS master and change the remaining APs on my network to use that as the WDS master. It seemed to be going well, every AP I switched to be using the second WDS master was showing up just fine. I then checked the old WDS master and realized that it was in 'backup' mode, having determined that the newer WDS master was the primary.
Long story short, if two WDS devices are on the same subnet, they will configure themselves as a master and a backup. Elsewhere on the forums, people suggest having two management vlans and WDS subnets while having the ssids that use use have consistent VLANS.
Someone had asked about using ACLs to mask the master WDS devices from each other on the same subnet -- it was recommended against, though I think I might try it. I'll respond with how that went.
For those who might be still interested in running multiple WDS masters in one subnet:
If you have no problem connecting all of your wds systems to one switch you simply configure the switch ports as protected. Et voila! AP will automatically register to any of the availablbe WDS systems until its limit (60) is reached. The rest of APs registers to the next system and so on.
