In Huawei campus networks, access authentication and authorization are implemented based on the AAA framework. After a user is successfully authenticated, the network enforces anauthorization result, which defines what network resources the user is allowed to access and how traffic is controlled. These authorization results are typically delivered by the authentication server or configured locally on network devices.
According to HCIP Datacom Campus Network documentation,authorization results focus on policy and access control attributes, not basic network parameter assignment. Common authorization items includeVLAN assignment,security group assignment, andACL application. VLANs determine the user’s logical network location, security groups enable group-based policy control, and ACLs restrict or permit traffic based on predefined rules. These elements directly affect access permissions and security enforcement.
AnIP address, however, does not need to be defined in the authorization result. In campus networks, IP addresses are usually assigned dynamically throughDHCP, either by a DHCP server or a DHCP relay function on network devices. The IP address allocation process is independent of user authorization and does not represent an access control policy.
Separating IP address assignment from authorization simplifies network design and improves scalability. It allows users to obtain IP addresses automatically while access rights are enforced consistently through identity-based policies. Therefore, among the given options,IP addressis not an item that must be defined in the authorization result.
Hence, the correct answer isB.
