You must provide network connectivity to hosts that fail authentication.

Understanding 802.1X Authentication:

802.1X is a network access control protocol that restricts access until the device or user is authenticated.

Guest VLAN Configuration:

When hosts fail authentication, they need to be placed in a separate VLAN to provide limited network access.

server-reject-vlan Command:

This command configures a VLAN for unauthenticated devices.

Ensures that devices that fail authentication are placed in a designated guest VLAN.

Configuration Example:

shell

Copy code

set protocols dot1x authenticator interface ge-0/0/1.0 server-reject-vlan guest-vlan
