华为交换机VTY用户界面属性配置教程用户通过Telnet或SSH方式登录设备实现本地或远程维护时，可以根据用户使用需求以及对设备安全的考虑来配置VTY， 除对VTY类型用户界面呼入呼出进行限制的ACL号、用户名和口令及用户界面的验证方式外其他参数设备均有缺省值，用户可以结合实际需求和安全性考虑选择配置。1、设置通过账号和密码登陆VTY界面1.1、进入VTY用户界面视图Huaweiuser-interface vty ? INTEGER The first user terminal interface to be configuredHuaweiuser-interface vty 0 4Huawei-ui-vty0-41.2、设置用户验证方式为AAA验证（即通过账号和密码登陆）Huawei-ui-vty0-4authentication-mode ? aaa AAA authentication none Login without checking password Authentication through the password of a user terminal interfaceHuawei-ui-vty0-4authentication-mode aaa1.3、设置登陆的账号和密码Huawei-ui-vty0-4qHuaweiaaaHuawei-aaalocal-user ? STRING User name, in form of userdomain. Can use wildcard *, while displaying and modifying, such as *isp,user*,*.Can not include invalid character / : * ? | Huawei-aaalocal-user 023 ? access-limit Set access limit of user(s) ftp-directory Set user(s) FTP directory permitted idle-timeout Set the timeout period for terminal user(s) password Set password privilege Set admin user(s) level service-type Service types for authorized user(s) state Activate/Block the user(s) user-group User groupHuawei-aaalocal-user 023 password ? cipher User password with cipher textHuawei-aaalocal-user 023 password cipher 1.4、设置账号的使用类型为Telnet或SSHHuawei-aaalocal-user 023 service-type telnet或Huawei-aaalocal-user 023 service-type ssh2、设置只通过密码登陆VTY2.1、置用户验证方式为密码验证Huawei-ui-vty0-4authentication-mode password2.2、设置登陆密码Huawei-ui-vty0-4set authentication password cipher ? STRING/ Plain text/cipher text passwordHuawei-ui-vty0-4set authentication password cipher 3、设置直接登陆VTY（此模式不安全）Huawei-ui-vty0-4authentication-mode none4、配置VTY用户界面的用户优先级缺省情况下，VTY用户界面对应的默认命令访问级别是0，实际工作如果对权限要求不是特别严格，一本设置为15级。Huawei-ui-vty0-4user privilege level ? INTEGER Set a priorityHuawei-ui-vty0-4user privilege level 155、启用VTY终端服务Huawei-ui-vty0-4shell6、设置用户超时断连时间Huawei-ui-vty0-4idle-timeout ? INTEGER Set the number of minutes before a terminal user times out(default: 10minutes)7、设置终端屏幕每屏显示的行数Huawei-ui-vty0-4screen-length ? INTEGER Display the number of lines on a screen (the value 0 indicates none split screen, and the default value is 24)8、设置终端屏幕显示的列数Huawei-ui-vty0-4screen-width ? INTEGER Screen width value, the default is 809、设置历史命令缓存条数Huawei-ui-vty0-4history-command ? max-size Set the size of the maximum history buffer, the default value is 10Huawei-ui-console0history-command max-size ? INTEGER The size of a history buffer10、VTY用户界面支持的登陆协议Huawei-ui-vty0-4protocol inbound ? all All protocols ssh SSH protocol telnet Telnet protocol11、配置VTY用户界面的最大个数VTY用户界面最大个数是指登录设备的Telnet用户和SSH用户的总和。当配置VTY用户界面最大个数为0时，任何用户（包括网管用户）都无法通过VTY登录到设备。如果要配置的VTY类型用户界面的最大个数小于当前在线用户的数量，则系统提示配置失败。如果要配置的VTY类型用户界面的最大个数大于当前最多可以登录用户的数量，就必须为新增加的用户界面配置验证方式。Huaweiuser-interface maximum-vty ? INTEGER The maximum number of VTY users, the default value is 512、配置VTY用户界面的基于ACL的登录限制Huawei-ui-vty0-4acl ? INTEGER Apply basic or advanced ACL ipv6 Filter IPv6 addressesHuawei-ui-vty0-4acl 2000 ? inbound Filter login connections from the current user interface outbound Filter logout connections from the current user interface13、查看VTY用户界面信息Huaweidisplay user-interface vty 0 4 Idx Type Tx/Rx Modem Privi ActualPrivi Auth Int 38 VTY 4 - 15 - N - + : Current UI is active.
