Performance Stress testing was performed on Cisco Secure ACS v3.1 to determine the maximum number of authentication requests the Cisco Secure ACS can serve per second. The results were generated using an authentication, authorization, and accounting (AAA) client simulator created internally. The hardware for testing the ACS system was configured as follows: Cisco Secure ACS HP Kayak 1.6 GHz, 256 MB RAM Cisco Secure ACS v3.1 Internal database with 100,000 users in the database 300 access points The following test results for LEAP, PEAP and EAP-TLS authentications are raw authentication rates. They do not include network latency, reliability, or user distribution factors. * Sustained LEAP-90 authentications per second *Sustained EAP-TLS-32 authentications per second *Sustained PEAP-32 authentications per second ________________________________ From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[EMAIL PROTECTED] On Behalf Of Hector J Rios Sent: Wednesday, September 24, 2008 3:28 PM To: [email protected] Subject: [WIRELESS-LAN] ACS issues... This semester we have seen in the ACS Passed Authentication Logs a lot of users passing multiple successful authentications, along with a good chunk of failed attempts also. So much so that our too auth servers are being overwhelmed. We use Cisco WiSMs (4.2.130.0) with lightweight APs and ACS v4.2 Build 124. Anybody having similar issues?
