你好,
没有办法回退到legacy模式。
authentication display {legacy | new-style}Example:Device# authentication display new-style
Sets the display mode for authentication and policy configuration.
The default display mode is
legacy.You can use this command to switch between legacy and C3PL display mode until you execute the first explicit Identity-Based Networking Services command.
After you enter the first explicit Identity-Based Networking Services command, for example when configuring a control class or control policy, the system displays a prompt to confirm whether you want to continue because this command will be disabled and you cannot revert to legacy mode.Note If you save the configuration while the new-style mode is enabled, and then perform a reload, the display mode is permanently set to new-style. The authentication display command is disabled and you cannot revert to legacy mode.If you boot the standby device while in new-style mode, the standby device will be in new-style mode and after switchover the device remains in new-style mode.
To switch back to legacy mode, you must use the authentication display legacy command and reload the standby switch.
可以看看authentication display legacy命令还可以使用吗?或者没有保存配置的话重启一下。可能现在authentication display legacy转换回原来的模式这个命令在这台2960上已经消失没法用了
另外,3850的文档也是说没法转换回去了:
After you enter the first explicit Session Aware Networking command, for example when configuring a control class or control policy, the system displays a prompt to confirm whether you want to continue because this command will be disabled and you cannot revert to legacy mode.
