工作... 某工程师说,系统版本问题无法设置Telnet、SSH...吧啦吧啦 telnet看,有如下报错: 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 %@%@rAHDYAir9w}~")"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                       //允许协议进入
