catalyst 3524 switch ip 地址的配置
直接进入默认的vlan 1中进行配置命令如下:
interface vlan1
ip address 172.16.1.3 255.255.0.0
即可。
在catalyst 中控制对telnet的访问
bluestudy_a(config)#access-list 2 permit 172.16.0.0 0.0.255.255 (定义标准的访问列表)
bluestudy_a(config)#line vty 0 15(进入telnet端口,最多允许16个telnet的会话)
bluestudy_a(config-line)#access-class 2 in(应用上述定义的访问列表,即只有172.16.0.0/16的网段可以实现对交换机的telnet会话)
设置交换机的enable 密码
bluestudy_a(config)#enable password bluestudybluestudy_a(config)#enable secret bluestudythe enable secret you have chosen is the same as your enable password.this is not recommended. re-enter the enable secret.
注:对于如上的密码,secret的优先级更高,优先起作用。
设置console口密码
bluestudy_a(config)#line con 0bluestudy_a(config-line)#password bluestudybluestudy_a(config-line)#
设置对telnet的密码:
bluestudy_a(config)#line vty 0 15bluestudy_a(config-line)#loginbluestudy_a(config-line)#password bluestudybluestudy_a(config-line)#
设置登陆用户名和密码:
bluestudy_a(config)#username bluestudy password bluestudybluestudy_a(config)#bluestudy_a#show runningcurrent configuration:!version 12.0no service padservice timestamps debug uptimeservice timestamps log uptimeno service password-encryption!hostname bluestudy_a!enable secret 5 $1$b1mb$p6xgv/py9wqvjy9mrhzfg/enable password bluestudy!username bluestudy password 0 bluestudy!ip subnet-zero!interface fastethernet0/1!interface fastethernet0/2!interface fastethernet0/3!interface fastethernet0/4!interface fastethernet0/5!interface fastethernet0/6!interface fastethernet0/24!interface gigabitethernet0/1!interface gigabitethernet0/2!interface vlan1ip address 172.16.1.3 255.255.0.0no ip directed-broadcastno ip route-cache!access-list 2 permit 172.16.0.0 0.0.255.255!line con 0password bluestudytransport input nonestopbits 1line vty 0 4access-class 2 inpassword bluestudyloginline vty 5 15access-class 2 inpassword bluestudylogin!endbluestudy_a#
