By cooperating with New H3C's security situation awareness, security linkage can be achieved. When the wired side detects a security issue with the wireless terminal, the linkage mechanism will be triggered to notify the wireless controller to block the terminal's wireless access, thereby ensuring network security.
Air interface optimization and terminal access strategy
• Support Radio Resource Optimization Policy (RROP), which refers to a collection of various wireless air interface optimization methods aimed at reducing or controlling the consumption of air interface media resources by management messages, broadcast messages, and invalid messages, leaving more resources to provide users with better wireless application services. RROP mainly includes air interface optimization strategies such as wireless service layer 2 isolation function, disabling low rate, adjusting Beacon transmission time interval, and disabling broadcast probe detection function.
• Support Station Access Control Policy (SACP), which restricts, controls, and guides wireless terminal access to better APs or wireless services; And control and schedule terminal traffic based on network applications, improve the overall performance of the wireless network, and enhance the experience and effectiveness of wireless access applications. SACP mainly includes terminal control strategies such as prohibiting weak signal client access, spectrum navigation, roaming navigation, load sharing, ignoring weak signal strength messages, fair scheduling of air interface transmission, traffic shaping based on client link conditions, and intelligent bandwidth guarantee.
RF resource management
RRM (Radio Resource Management) uses systematic intelligent radio frequency management to monitor real-time environmental issues such as channel utilization, channel interference, and signal conflicts of the air interface. It adjusts the working channel, bandwidth, power, and other parameters of the radio frequency in a timely manner to maintain the optimal state of radio frequency resources. It can achieve automatic network deployment and automatic network repair.

Flexible forwarding strategy
When connected through a wide area network, wireless access devices are deployed at branch offices, while wireless controllers are deployed at headquarters. The traditional forwarding mode is that data packets are sent from the wireless access devices to the wireless controllers, and then centrally forwarded by the wireless controllers. The product can directly convert data packets into wired format packets on wireless access devices, allowing data packets to be forwarded locally without passing through wireless controllers, greatly saving wired bandwidth. At the same time, it also supports flexible policy forwarding, allowing terminals within wireless services to achieve traffic concentration and local forwarding selection based on forwarding policies, thereby releasing the pressure of export bandwidth and reducing network bandwidth costs.
Supports IPv4/IPv6 dual stack (Native IPv6)
Fully supports IPv6 features, with devices implementing IPv4/IPv6 dual protocol stacks. Regardless of whether the original wired network is IPv4 or IPv6, it can automatically register and provide WLAN services on the wireless controller through broadcasting, multicast, DHCP option43, DNS, and other methods, without becoming an information island in the network.
