detailed description of the LEDs and additional troubleshooting tips.
Misconfigured Access Point IP addressIP address misconfiguration can occur when you are re-addressing a segment of your mesh network
and you start at the mesh access point connected to the wired network (RAP). To avoid this problem,
always start the IP addressing changes from the farthest access point and work your way back to the
root access point. This problem might also happen if you move equipment such as uninstalling an mesh
access point and then redeploying with a different IP subnet in another physical location on the mesh
network.
Another option to fix this misconfigured IP address is to physically take a controller in Layer 3 mode
with a root access point to the location of the misconfigured mesh access point. Set the bridge group
name for the root access point to match the misconfigured access point. Add the access point’s MAC
address to the controller’s filter list. When the misconfigured access point appears in the controller’s
Summary page, configure the access point with an IP address.
If you are using a static IP address on the access point and plan on redeploying the access point on
another subnet, perform a clear config command from the controller for that access point while it is
joined before you remove it from the network.
Verifying the Controller MAC Filter ListPrior to activating your access point, you must ensure that the access point MAC address has been
added to the controller MAC Filter list and that Mac Filter List is enabled. To view the MAC addresses
added to the controller MAC filter list and ensure the MAC filter list is enabled, you can use the
controller CLI or the controller GUI.
