Why does an AP restart repeatedly or its IP address change frequently

10

The possible causes are:

During an AP upgrade, if the AP fails to establish a connection with the FTP server or SFTP server, the CAPWAP module restarts the AP.

In Layer 3 networking, if Option 43 is not configured on the DHCP server, an AP cannot obtain the AC's IP address to establish a CAPWAP tunnel with the AC. As a result, the AP restarts and obtains IP addresses repeatedly.

An AP restarts repeatedly or its IP address changes frequently
During an AP upgrade through FTP or SFTP, if the AP fails to establish a connection with an FTP or SFTP server, the CAPWAP module makes the AP restart. In Layer 3 networking, if Option 60 or Option 43 is not configured on the DHCP server, an AP cannot obtain the AC's source IP address to establish a CAPWAP tunnel with the AC. As a result, the AP restarts and obtains IP addresses repeatedly. You can run the reset ip pool { interface pool-name | name ip-pool-name } { start-ip-address [ end-ip-address ] | conflict } command to release a conflicting IP address.

An AP fails to obtain an IP address
If the management address pool for APs is created on an AC, run the display ip pool name ip-pool-name used command on the AC. If the command output displays an AP's MAC address and a corresponding IP address, the AP has obtained an IP address. You can also run the following command to check whether an AP has obtained an IP address: - For V200R005 or earlier version: display ap-run-info id ap-id - For V200R006 or a later version: display ap all

Why does the system repeatedly prompt for restart during the installation of network extension controls
A Windows 64-bit operating system is used, but the current SSL VPN version for the network extension function does not support Windows 64-bit operating systems. Change the Windows 64-bit operating system into another operating system.

An AP fails to obtain an IP address through DHCP
Perform the following steps to locate the fault: 1. Check whether the AP is configured to obtain an IP address through DHCP. 2. Check whether the Layer 2 link between the AP and DHCP server is working properly. 3. Run the display ip pool name ip-pool-name used command on the DHCP server to check whether the AP has obtained an IP address.

Will the AP ID be changed after an AC restart
No.
