设置cisco登陆时显示的警示性信息-banner

 

Cisco 配置banner消息

旗标（banner）消息能够用来警示***者。

 

Router(config)#banner ?

LINE             c banner-text c, where 'c' is a delimiting character

exec             Set EXEC process creation banner

incoming         Set incoming terminal line banner

login            Set login banner

motd             Set Message of the Day banner

prompt-timeout Set Message for login authentication timeout

slip-ppp         Set Message for SLIP/PPP

 

缺省时旗标是关闭的。旗标命令通常包括5个不一样的命令：

●banner exec－－规定并启用一个消息，当在路由器上建立一个EXEC过程时显示（当用户认证成功登录后显示）。

●banner incoming－－规定并启用一个旗标，当有来自网络中某台主机链接到终端链路时显示。

●banner login－－规定并启用一个旗标，在用户名和口令登陆提示以前显示。

●banner motd－－规定并启用一个MOTD（message-of-the-day）旗标。

●banner slip-ppp－－规定并启用一个旗标，当SLIP或PPP链接创建时显示。

login和motd 的banner只须要作一个，exec在认证成功后显示

Router(config)# banner motd #
