Small- and medium-sized enterprises are characterized by small network scale, a small number of concurrent online users, and dispersed network sites. To support these enterprises, Huawei proposes the CloudCampus Solution to provide services through the public cloud. This solution realizes centralized multi-tenant management, plug-and-play network devices, and batch deployment of network services. Compared with the traditional network architecture and deployment mode, this solution provides a shorter network deployment period, lower maintenance costs, and better network scalability.
The authentication server is deployed on the Internet, so packets between the device and server may need to traverse a NAT device. However, Portal protocol packets cannot traverse the NAT device. To address this issue, Huawei Agile Cloud Authentication (HACA) allows the device and server to establish a connection for Portal authentication. Currently, only iMaster NCE-Campus can be used as an HACA server.
HACA supports Layer 2 Portal authentication or MAC address-prioritized Layer 2 Portal authentication. HACA does not support Layer 3 Portal authentication or MAC address-prioritized Layer 3 Portal authentication.
HACA does not support administrative access, IPSec, SSL VPN, IP session, L2TP, VM, 802.1X, and independent MAC address authentication.
