華為交換機(jī)VTY用戶界面屬性配置教程

華為交換機(jī)VTY用戶界面屬性配置教程用戶通過Telnet或SSH方式登錄設(shè)備實(shí)現(xiàn)本地或遠(yuǎn)程維護(hù)時(shí)，可以根據(jù)用戶使用需求以及對設(shè)備安全的考慮來配置VTY，除對VTY類型用戶界面呼入呼出進(jìn)行限制的ACL號(hào)、用戶名和口令及用戶界面的驗(yàn)證方式外其他參數(shù)設(shè)備均有缺省值，用戶可以結(jié)合實(shí)際需求和安全性考慮選擇配置。1、設(shè)置通過賬號(hào)和密碼登陸VTY界面1.1、進(jìn)入VTY用戶界面視圖[Huawei]user-interfacevty?
