Client device address assignment following authentication

A non-transitory machine readable storage medium having stored thereon machine readable instructions to cause a computer processor to:

• detect an authentication request transmitted by a client device;
• assign a first role to the client device in response to the authentication request when the client device is associated with a first VLAN and the first VLAN's corresponding DHCP server;
• assign the client device to a second role in response to detecting the authentication request;
• decline a DHCP request from the client device while the client device is assigned to the second role, wherein the second role includes a rule to decline the DHCP request until an Extensible Authentication Protocol (EAP) success message is received from the client device;
• and
• assign the client device to a third role when the client device is associated with a second VLAN and the second VLAN's corresponding DHCP server when the EAP success message is received from the client device.

A system comprising:

• a network device comprising a hardware processor, wherein the hardware processor includes instructions to:
• assign a first role to a client device in response to an authentication request when the client device is associated with a first VLAN the first VLAN's corresponding DHCP server to indicate that the client device has not been authenticated;
• receive a DHCP request from the client device while the client device is assigned to a second role that indicates that any DHCP requests and DHCP renew messages from the client device are to be denied, wherein the second role overwrites the first role;
• decline the DHCP request from the client device while the client device is assigned to the second role until an Extensible Authentication Protocol (EAP) success message is received from the client device;
• and
• assign the client device to a third role when the client device is associated with a second VLAN and the second VLAN's corresponding DHCP server when the EAP success message is received from the client device.
