ArubaOS and Controllers

vrrp and dhcp

I have two aruba controllers with a common vlan, where vrrp is configured for the common vlan on the two controllers. Can I configure the aruba controllers to provide dhcp for clients on the vlan? If so, how does the backup know that it shouldn't be providing dhcp? In case of a failure with the master, how does the new master know what ip addresses the previous master has handed out?

Split Scopes

You need to split the scopes between both controllers, because there is no synchronization of DHCP activity between controllers.

Re: vrrp and dhcp

There is no sync between instances of DHCP on multiple controllers, I would recommend you look at a server based solution. The DHCP server is really intended for small deployments and guest access, and it doesn't have all the services that a server based DHCP solution can provide.
