Can I increase the number of APs that can act as DHCP servers?

On a similar thought process what is the chance that we can increase the number of APs that can act as DHCP servers? If you have a site with four buildings connected by WAN links you can't have an AP in each building acting as a DHCP server as you are limited to a primary and a secondary. I commonly use the integrated DHCP server functionality for guest users.

Making cloud-only solutions is not a fix to a number of problems as some customers, particularly customers who handle public or sensitive information, do not want any part of their wireless network in the cloud.

Hi Crowdie,

The DHCP service is individual to the AP/subnet, there is no concept of primary/secondary in the SSID settings etc.

You can create multiple DHCP server scopes under advanced - common objects - DHCP - you can then create different scopes and apply those to multiple AP's.

If each site is on a different subnet/vlan, then each site can have a dedicated DHCP server running on a local AP.

If each site was running on the same vlan, then the only way to have a DHCP server per site would be to split the scope across the 4 sites.

There is further information about the setup of DHCP services within the help file in the HiveManager.

Aerohive offers both cloud and on-premise versions of our HiveManager so that customers with restricted traffic policies can keep everything local. The difference between our solution and other vendors is that no user data or control traffic is sent to the cloud. The AP's only communicate with the management system for reporting and configuration updates.

I suppose the point I was making is why is there a two AP serving as DHCP server limit per VLAN? Why can't we have say four APs serving as DHCP servers per VLAN?

The point re the cloud was that a number of questions have been answered by "ID Manager does this" but if the customer does not want any part of their wireless solution in the cloud, and I have a number of customers who have this view, then a cloud based solution, such as ID Manager, does not resolve the issue. However, if Aerohive was to make an on-premise version of ID then we would have a solution. Hint hint.

"The DHCP service is individual to the AP/subnet, there is no concept of primary/secondary in the SSID settings etc."

The "primary" and "secondary" DHCP server terms are taken from the DHCP Relay definitions (Configure -> Advanced Configuration -> Common Objects -> DHCP Server & Relay).
