Centralised licensening - multiple remote Masters to centralised licensing

Hi,

 

I read quite a bit about it and and trying to figure out if this is supported.

I have enabled centralised licensing with bigger pool of licenses on Master-Local setup of controllers in data center. I can see all licences combined. So far there is no VRRP setup in place yet.

 

Now I have couple single masters in different locations (they may or not be behind the NAT). Can I use point those remote controllers back to data center ones to use that big pool? If yes how? just by pointing to MASTER ip in data center in theirs filed "License Server IP" without enabling centralised licensing on all those remote masters?

Yes you can if they are routable addresses.  Nat boundaries would create additional difficulty and should be avoided.

 

Please see the Centralized Licensing Chapter here:  http://www.arubanetworks.com/techdocs/ArubaOS_65x_WebHelp/Web_Help_Index.htm#ArubaFrameStyles/New_Licenses/Multi__Network.htm?Highlight=centralized licensing

 

Double-check any scenario with your local Aruba Sales Engineer before making a major change in your licensing topology, however.

Re: Centralised licensening - multiple remote Masters to centralised licensing

So on the Centralized Licensing tab I have only "License Server IP" filled and it does not work (I am sure there is pleny of licensing on that server I am trying to connect). I can ping it from the controller. To I need to enable "Enable Centralized Licensing" on the client controller?

 

How to troubleshoot licensing issues?

Re: Centralised licensening - multiple remote Masters to centralised licensing

So after looking at this, the server side has all hart beats but clinet has all missed. The problem can be  Client IP which is behind the NAT like and goes like 192.168.1.100

I do have ablitiy to do 1:1 translation but how does central server suppose to know not to send hartbeat back to 192.168.1.100 but public IP I set in 1:1 translation?

 

My problem is lack of proper comunication back to the client, can I change sth in the routing/firewall of central server or client?

I am not sure if this was tested or supported with NAT.

Maybe there is a way to statically set response diferently but I simply bypassed it by adding extra vlan with public IP and setting it as controller IP and now it works fine
