Recently, a customer's AAA was not correctly configured, causing him to be locked out of the device. Because it is a multi-switch stack unit in the production environment, it is not allowed to restart and ignore the configuration, remote operations are required to solve the problem, which undoubtedly increases the difficulty of solving the problem.
