Usage Guidelines

Usage Scenario

In inter-AC roaming scenarios, ACs may need to exchange sensitive information such as the user name and password. The PSK is required to protect data transmitted between the ACs.



The PSK must be set to the same on ACs. Otherwise, the CAPWAP tunnel cannot be set up between the ACs.


# Set the PSK used for encrypting sensitive information between ACs to huawei@123.
