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 bluestudy bluestudy_a(config)#enable secret bluestudy The 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 0 bluestudy_a(config-line)#password bluestudy bluestudy_a(config-line)#
设置对telnet的密码:
bluestudy_a(config)#line vty 0 15 bluestudy_a(config-line)#login bluestudy_a(config-line)#password bluestudy bluestudy_a(config-line)#
设置登陆用户名和密码:
bluestudy_a(config)#username bluestudy password bluestudy bluestudy_a(config)# bluestudy_a#show running Current configuration: ! version 12.0 no service pad service timestamps debug uptime service timestamps log uptime no 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 VLAN1 ip address 172.16.1.3 255.255.0.0 no ip directed-broadcast no ip route-cache ! access-list 2 permit 172.16.0.0 0.0.255.255 ! line con 0 password bluestudy transport input none stopbits 1 line vty 0 4 access-class 2 in password bluestudy login line vty 5 15 access-class 2 in password bluestudy login ! end bluestudy_a#
