All Comware V7 Platform Wireless Controller Products
After the above model wireless controller is upgraded to the above version, when the AP management segment address pool is less than twice the number of APs, it may lead to the issue that APs cannot obtain IP addresses and cannot register online.
The AP version corresponding to the above AC version has modified the format of obtaining IP address. After the AP is upgraded from the old version to the above version, the DHCP Server needs to assign a new IP address to the AP because the DHCP Client ID of the AP has changed, but the IP address assigned to the AP before the upgrade has not yet been released. If the number of available addresses in the address pool is less than twice the number of APs, the DHCP address pool will be exhausted and no IP address can be assigned, thus the AP cannot register online.
Upgrade to version R5452P06 or R5453 (not included) or above will solve the problem at all.
