Hi;

What happens if my only ACS goes down? ACS is active on my access switches.

What deployment scenario are we talking about here? For example, with 802.1X deployments there is a feature (called Inaccessible Authentication Bypass) that allows you to provide access to a specific VLAN in the scenario where connectivity to the ACS server is compromised. Is that something may help you?

Request will go to secondary acs. If switch tries to authenticate , request first goes to primary acs, but if there is no response from that acs, switch will send that request to secondary acs.
