Wireless Access

Is it possible to use centralized licensing across public IPs? If so, what needs to be allowed through the firewall for this to take place.

Thanks.

Controllers, needed to have 2 masters and they are seperated physically and logically into different networks, but can reach each other via public addresses.

Hi Michael Haring,

It doesn't matter whether a controller is a master or a local, Centralised Licensing is independent of this setup.

1. You have to Enable the centralised Licensing on both the controllers and specify the licensing server IP (Ex Master1) on the other controller (Ex: Master 2). 

2. Configure VRRP if you want to enable Backup license server.

2. Ensure there is IP reachable between those two Controllers.

3. Allow the following ports in the Firewall if any.

• 1. UDP Source port                              = 8211
• 2. UDP destination port                        = 8211
• 3. Keepalives  timer                             = Sent every 30 seconds
• 4. Keepalives  direction                       = Sent in both directions: Server==>client, client==>server   

Please feel free for any further help on this.
