CLIENT DEVICE ADDRESS ASSIGNMENT FOLLOWING AUTHENTICATION

摘要

Methods and systems are described for assigning the proper internet protocol (IP) address to a client device following authentication of the client device on a network. In particular, at commencement of an authentication procedure of the client device, a role is associated with the client device that denies all DHCP renews/requests. By assigning a role to the client device 103 with a “deny DHCP renew/request” rule at the commencement of an authentication procedure, the systems and methods described herein ensure that a race condition does not allow the client device to renew an IP address in an old segment of the network. Accordingly, the client device may avoid a possibly improper IP address in a segment of the network system in which the client device is no longer associated with or operating on.

1. A non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, cause performance of operations comprising:
detecting an authentication request transmitted by a client device while the client device is assigned a first role such that (a) the client device is associated with a first VLAN and (b) DHCP requests received from the client device are forwarded to at least one DHCP server associated with the first VLAN; responsive to the detecting operation, assigning the client device to a second role such that DHCP requests received from the client device are declined; and responsive to successfully completing authentication of the client device, assigning the client device to a third role such that (a) the client device is associated with a second VLAN and (b) DHCP requests received from the client device are forwarded to at least one DHCP server associated with the second VLAN.
