Troubleshooting Fast BSS Transition

ArubaOS provides various troubleshooting options to verify the Fast BSS Basic Service Set. A BSS is a set of interconnected stations that can communicate with each other. BSS can be an independent BSS or infrastructure BSS. An independent BSS is an ad hoc network that does not include APs, whereas the infrastructure BSS consists of an AP and all its associated clients. Transition functionalities.

In decrypt-tunnel mode and bridge mode, each r0 key generates up to four r1 keys and the managed device pushes each r1 key to the corresponding AP. The following commands help verifying the pushing functionality:

Execute the following command to view all the r1 keys that are stored in an AP:

You can execute the following command to remove an r1 key from an AP when the AP does not have a cached r1 key during Fast BSS Basic Service Set. A BSS is a set of interconnected stations that can communicate with each other. BSS can be an independent BSS or infrastructure BSS. An independent BSS is an ad hoc network that does not include APs, whereas the infrastructure BSS consists of an AP and all its associated clients. Transition roaming:
