Complete these steps in order to configure 802.1x authentication on the switch:
Configure following commands on switch in Global configuration mode:
aaa authentication dot1x default group radius
radius-server host IP_address_of_ACS
radius-server key shared_key
Go into the interfaces connected to the clients using "interface interface_id" command and configure the following:
switchport access vlan
dot1x port-control auto
dot1x timeout quiet-period 15
dot1x timeout tx-period 3
In the case of Microsoft Windows XP client, for MAC authentication to work, disable the client in order to send an EAP request, so that switch can consider it as agentless host, and initiates the MAC authentication bypass process. This is the registry fix on Windows XP test machine:
Maximum users supported by the ACS internal database-There is no theoretical limit to the number of users the ACS internal database can support. We have successfully tested ACS with databases in excess of 100,000 users. The practical limit for a single ACS authenticating against all its databases, internal and external, is 300,000 to 500,000 users. This number increases significantly if the authentication load is spread across a number of replicated ACS instances.
