华为S5700没法telnet、ssh【已解决】

工做...
    某工程师说，系统版本问题没法设置Telnet、SSH...吧啦吧啦
    telnet看，有以下报错：
         Reason="The channel configuration is incorrect."
    查看配置：
        user-interface vty 0 4
             authentication-mode aaa
        aaa
             authentication-scheme default
             authorization-scheme default
             accounting-scheme default
             domain default
             domain default_admin
             local-user admin password irreversible-cipher %@%@rA*HDYAir9w}~")"qec7AO_db17$)!c553IMp].#*=|>U_deO%@%@
             local-user admin service-type http telnet ssh

    解决方法：
        user-interface vty 0 4
             authentication-mode aaa
             protocol inbound all                       //容许协议进入
