1：配置telnet密码登陆
5506(config)#enable password cisco
5506(config)#passwd cisco #已加密
5506(config)#telnet192.168.1.2 255.255.255.255 inside
5506(config)#telnettimeout 10 #默认5分钟超时
R2#192.168.1.1
Trying 192.168.1.1 ...Open

3：配置SSH远程登陆
5506(config)#ssh 192.168.1.0 255.255.255.0 inside
5506(config)#ssh timeout 10
5506(config)#aaa authentication sshconsole LOCAL #LOACL是关键字
