Network access control is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network. [3] NAC might integrate the automatic remediation process (fixing non-compliant nodes before allowing access ...
Network Admission Control (NAC) refers to Cisco's version of network access control, which restricts access to the network based on identity or security posture.When a network device (switch, router, wireless access point, DHCP server, etc.) is configured for NAC, it can force user or machine authentication prior to granting access to the network.
Cisco NAC Appliance, formerly Cisco Clean Access (CCA), was a network admission control (NAC) system developed by Cisco Systems designed to produce a secure and clean computer network environment.
The authenticator is a network device that provides a data link between the client and the network and can allow or block network traffic between the two, such as an Ethernet switch or wireless access point; and the authentication server is typically a trusted server that can receive and respond to requests for network access, and can tell the ...
Instead they use what is called a Network Access Code (NAC) which is included outside of the digital voice frame. This is a 12-bit code that prefixes every packet of data sent, including those carrying voice transmissions. The NAC is a feature similar to CTCSS or DCS for analog radios.

The EX switches support a range of features including high availability and network access control (NAC). The NAC support, which Juniper calls Unified Access Control (UAC), enables the switches to enforce access policies rather than rely on firewalls, VPN gateways, or switches made by other vendors.
