[Cisco ACS 5.4] thousands of hosts - performance?

Hi,

I want to configure Machine authentication combined with PEAPv1 in ACS 5.4

This feature works but I'm wondering if it will support 20k MAC addresses...

My appliance is CS-ACS1121.

I read that ACS 5.4 supports 300k internal hosts (and MAC addresses) : http://www.cisco.com/en/US/docs/net_mgmt/cisco_secure_access_control_system/5.2/migration/guide/Migration_Deploy.html#wp1054675

I'm afraid of decreasing too much the performance of ACS.

At each connection, ACS should compare MAC Address of the client with its database. (20k in my case)

My ACS is already handling 30k EAP-TLS connections a day.

Do you think that ACS could handle MAC authentication ?

I dont know how much resources it take...


Thanks for your help,

Patrick
