Chapter 1 Configuring Network Admission Control
Prerequisites for NAC
Prerequisites for NAC
When configured to support NAC, the ASA functions as a client of a Cisco Secure Access Control
Server, requiring that you install a minimum of one Access Control Server on the network to provide
NAC authentication services.
Guidelines and Limitations
Following the configuration of one or more Access Control Servers on the network, you must use the
aaa-server command to name the Access Control Server group. Then follow the instructions in the
“Configuring a NAC Policy” procedure on page 1-8.

1. If you start a clientless SSL VPN session and then start an AnyConnect client session from the portal, 1 session is used in total. However, if you start the
AnyConnect client first (from a standalone client, for example) and then log into the clientless SSL VPN portal, then 2 sessions are used.
2. The maximum combined VPN sessions of all types cannot exceed the maximum sessions shown in this table.
3. A shared license lets the ASA act as a shared license server for multiple client ASAs. The shared license pool is large, but the maximum number of sessions
used by each individual ASA cannot exceed the maximum number listed for permanent licenses.
