About smart operations and maintenance
By integrating cloud, network, and endpoint, H3C Cloudnet smart operations and maintenance (O&M) provides network monitoring anywhere anytime and device O&M with ease. It offers excellent user experience through displaying network monitoring data in a clear and organized way. In addition, smart O&M provides abundant data, such as basic device information, health information, channel heatmaps, client event history and health information, greatly lowering the cost for network inspection.
Restrictions and guidelines
· Only H3C WLAN devices except for Xiaobei routers and WTU420 devices support smart O&M.
· For ACs of a version lower than 5412, some functions are unavailable or the displayed data is incorrect. Please upgrade your software to the most recent version.
· For cloud-managed APs, you can use smart O&M functions without enabling the smart O&M feature. For specific cloud-managed APs, some smart O&M functions are unavailable.
· If no device exists in a site, no data will be displayed.
