Why do we need a NAC solution?

NAC systems can play a vital role in automatically identifying devices as they connect to the network and providing access that does not potentially compromise security. For example, when a personal mobile device connects, it can be granted access only to the Internet and not to any corporate resources.

What are the three key activities performed by NAC nse2?

What are the three key activities performed by NAC? (Choose three.) Discover all devices on the network. Profile all devices to identify what access they should have. Provide appropriate network access to devices.

What is extreme NAC assessment agent?

Extreme Networks NAC provides agent-based or agent-less endpoint assessment capabilities to determine the security posture of connecting devices.

Can ExtremeControl provide visibility and control on non extreme network devices?

ExtremeControl unifies the security of wired and wireless networks, providing visibility and control over users, devices and applications. It enables granular policy controls to help users comply with policies and compliance obligations in heterogeneous endpoint environments.

What is port-based access control?

Port-based network access control regulates access to the network, guarding against transmission and reception by unidentified or unauthorized parties, and consequent network disruption, theft of service, or data loss. Data frames are transmitted and received using the MAC Service specified in IEEE Std 802.1AC.

What is Cisco NAC?

Cisco Network Admission Control (NAC) is a set of technologies and solutions that uses the infrastructure of a computer network for network access control (NAC) and network protection. All access methods are monitored, including wireless devices, local area networks (LAN) and remote access wide area networks (WAN).

Digital certificates are an essential part of 802.1x authentication. Certificates are shared, checked, and verified before any device is allowed to connect to the network. A secure channel is used during the negotiations, so all credentials are safe from prying eyes.

What is port security on a switch?

Port security is a layer two traffic control feature on Cisco Catalyst switches. It enables an administrator configure individual switch ports to allow only a specified number of source MAC addresses ingressing the port.

Which subcommand overrides the default action to take upon a security violation?

4. (Optional) Use the switchport port-security violation {protect | restrict | shutdown} interface subcommand to override the default action to take upon a security violation (shutdown).

What is the default port security violation mode?

Switchport Violations These are described in more detail below: Shutdown – When a violation occurs in this mode, the switchport will be taken out of service and placed in the err-disabled state. The switchport will remain in this state until manually removed; this is the default switchport security violation mode.

How do I check my port security violations?

Here is a useful command to check your port security configuration. Use show port-security interface to see the port security details per interface. You can see the violation mode is shutdown and that the last violation was caused by MAC address 0090.

Which action will bring an error disabled switch port back to an operational state?

Which action will bring an error-disabled switch port back to an operational state? Clear the MAC address table on the switch. Remove and reconfigure port security on the interface. Issue the switchport mode access command on the interface.
