The string “&<1-10>” means that up to 10 port listscan be provided.DescriptionUse the dot1x guest-vlan command to enable the guest VLAN function for ports.Use the undo dot1x guest-vlan command to disable the guest VLAN function for ports.After 802.1x and guest VLAN are properly configured on a port:z If the switch receives no response from the port after sending EAP-Request/Identity packets to theport for the maximum number of times, the switch will add the port to the guest VLAN.z Users in a guest VLAN can access the guest VLAN resources without 802.1x authentication.However, they have to pass the 802.1x authentication to access the external resources.
