Using DHCP Option 43

Using DHCP Option 43

You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling the access point to find and join a controller. Refer to the product documentation for your DHCP server for instructions on configuring DHCP Option 43. For additional information, refer to the “Configuring DHCP Option 43” section on page G-1.

Misconfigured Bridge Shared Secret Key

If an access point has a misconfigured bridge shared secret key, it is not allowed to join the mesh network. If Enable Zero Touch Configuration is checked on your controller, the access point can obtain the shared secret key from the controller or a neighbor access point.

If Enable Zero Touch Configuration is not checked, you might need to check the feature to allow the access point to get a new bridge shared secret key (refer to the “Enabling Zero Touch Configuration on the Controller” section on page 2-10).

Misconfigured MESH Access Point IP address

IP address misconfiguration can occur when you are re-addressing a segment of your mesh network and your first IP address change is the IP addresses of the RAP connected to the wired network. To avoid this problem, always start the IP addressing changes from the farthest access point and work your way back to the RAP. This problem might also happen if you move equipment; for example, you uninstall an access point and redeploy it in another physical location on the mesh network with a different IP subnet.

Another option to fix this misconfigured IP address is to physically take a controller in L2 mode with a RAP to the location of the misconfigured MAP. Set the bridge group name for the RAP to match the misconfigured MAP. Add the MAP’s MAC address to the controller’s filter list and check Enable Zero Tough Configuration. When the misconfigured MAP displays on the controller’s Summary page, you can properly configure the access point.
