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 %@%@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                       //允许协议进入
