Information About NAC—L2 IEEE 802.1x
The NAC layer 2 (L2)
IEEE 802.1x feature extends NAC support to Layer 2 switches and wireless access
points. Network admission control (NAC) is a Cisco Systems sponsored initiative
that uses the network infrastructure to enforce security policy compliance on
all devices seeking to access network computing resources, thereby limiting
damage from viruses and worms.
Using NAC, you can
provide network access to endpoint devices such as PCs, PDAs, and servers that
are verified to be fully compliant with an established security policy. NAC can
also identify noncompliant devices and deny them access, place them in a
quarantined area, or give them restricted access to computing resources.
