Should i enable 802.1x authentication

Configures local , chap-radius or eap-radius as the primary password authentication method for port-access. The default primary authentication is local. For switches covered in this guide, you must use the password port-access command to configure the operator username and password for Provides options for secondary authentication.

The none option specifies that a backup authentication method is not used. The authorized option allows access without authentication. To enable the switch to perform If you select either eap-radius or chap-radius for the authentication method, configure the switch to use 1, 2, or 3 RADIUS servers for authentication.

The following syntax shows the basic commands. Specifies an encryption key for use during authentication or accounting sessions with the specified server. Use this option only if the specified server requires a different key than configured for the global encryption key.

Specifies the global encryption key the switch uses for sessions with servers for which the switch does not have a server-specific key. This key is optional if all RADIUS server addresses configured in the switch include a server-specific encryption key. The no form of the command removes the global encryption key. After configuring Activates While On the specified ports, blocks inbound and outbound traffic and restarts the This happens only on ports configured with control auto and actively operating as After you enable As documented in the IEEE In both ingress and egress directions by disabling both the reception of incoming frames and transmission of outgoing frames.

Only in the ingress direction by disabling only the reception of incoming frames. The port is configured as an edge port in the network using the spanning-tree edge-port command. The Outgoing traffic with unknown destination addresses is flooded on unauthenticated The Wake-on-LAN feature is used by network administrators to remotely power on a sleeping workstation for example, during early morning hours to perform routine maintenance operations, such as patch management and software updates.

The aaa port-access controlled-direction in command allows Wake-on-LAN traffic to be transmitted on an For example, firewall rules on other network devices and VLAN rules may prevent these packets from traversing the network.

Using the aaa port-access controlled-direction in command, you can enable the transmission of Wake-on-LAN traffic on unauthenticated egress ports that are configured for any of the following port-based security features:. Because a port can be configured for more than one type of authentication to protect the switch from unauthorized access, the last setting you configure with the aaa port-access controlled-direction command is applied to all authentication methods configured on the switch.

To display the currently configured When an Configuring When a PC is connected through an IP phone to a switch port that has been authorized using Mixed port access mode allows Instead of having just one client per port, multiple clients can use the guest VLAN.

If an authenticated client becomes authorized on its untagged VLAN as the result of initial authentication or because of an untagged packet from the client, then all Old-school internet users remember point-to-point protocol PPP as how they got online in the days of dialup modems, although the protocol also had use as a tunneling method over DSL and as part of some VPNs. This was fine for home users, but enterprises generally required something more robust.

Extensible authentication protocol EAP was designed to meet those needs. EAP sat inside of PPP's authentication protocol and provided a generalized framework for several different authentication methods.

EAP was supposed to head off proprietary authentication systems and let everything from passwords to challenge-response tokens and public-key infrastructure certificates all work smoothly with PPP. With standardized EAP, interoperability and compatibility of authentication methods became simpler. For example, when you dialed into a remote-access server RAS that used EAP for security, the RAS didn't need to know any of the details about the authentication system; it just had to coordinate things between you and the authentication server.

This brings us to IEEE As the name implies, this is a standard for passing EAP over a wired or wireless local area network. With It's authentication and nothing more.

You can also use One of the key benefits of This makes A client connecting to the wireless network first connects to the NAS. You can configure By default, for The NAS requests authentication credentials from a wireless client. The wireless client sends authentication credentials to the NAS.

The RADIUS server checks the user identity and authenticates the client if the user details are available in its database. The NAS forwards this message to the client and the client must re-authenticate with appropriate credentials.
