For example, some users who do not have an authentication account must first log in to the official website of a carrier and apply for a member account, or log in using a third-party account such as a Twitter or Facebook account. This is because a domain name is easier to remember. Sometimes, defining a free rule by domain name is simpler and more convenient than defining a free rule by IP address. An ACL-based free rule can also define the name of a destination domain that users can access before being authenticated. Both the rules can specify the destination IP address that users can access before being authenticated. A common free rule is determined by parameters such as the IP address, MAC address, interface, and VLAN, while an ACL-defined free rule is determined by ACL rules. You can configure either a common free rule or an ACL-defined free rule. The user is then allowed to access the network.Ī free rule allows users to obtain certain network access rights before they are authenticated, to meet basic network access requirements. If the hash result is the same as that carried in the received packet, the RADIUS server sends an authentication accept packet to the access device, indicating that MAC address authentication of the user is successful. Based on the received random value, the RADIUS server performs hash processing on the combination of the user MAC address, shared key, and random value in the local database using the MD5 algorithm.
ACCESS DEVICE VIA MAC ADDRESS FOR MAC
It then encapsulates the user name, hash result, and random value into a RADIUS authentication request packet, and sends the packet to the RADIUS server for MAC address authentication.
ACCESS DEVICE VIA MAC ADDRESS PASSWORD
Multiple terminalsĬonnected to an interface use the same user name and password for MAC addresses are easy to obtain, for example, when a few printersĪpplicable to a network with reliable terminals. Either the MAC address of the terminal or a specified passwordĪpplication to a network with a small number of terminals whose
