1、 根据拓扑完成上图 ，可以配置pc的地址为192.168.1.1-192.168.1.4
2、 配置安全端口
Switch>enable
switch#conf t
Switch(config)#interface f0/1
Switch(config-if)#switchport mode access 配置access模式
Switch(config-if)#switchport port-security 开启安全端口
Switch(config-if)# do show port inter f0/1 查看安全端口信息
Port Security : Enabled 已经开启
Port Status : Secure-up
Violation Mode : Shutdown
Aging Time : 0 mins
Aging Type : Absolute
SecureStatic Address Aging : Disabled
Maximum MAC Addresses : 1
Total MAC Addresses : 0
Configured MAC Addresses : 0
Sticky MAC Addresses : 0
Last Source Address:Vlan : 0000.0000.0000:0
Security Violation Count : 0
Switch(config-if)#switchport port-security maximum 2
设置最大接入MAC地址数为2
Switch(config-if)#switchport port-security mac-address sticky
自动获得接入设备的MAC
Switch(config-if)#switchport port-security violation ?
违规处理方式
protect Security violation protect mode
?；? 丢弃数据，不告警
restrict Security violation restrict mode
抵制 –丢弃数据，发告警
shutdown Security violation shutdown mode
关闭- 丢弃数据，发告警并关闭链路
Switch(config-if)#switchport port-security violation protect
选择违规处理方式为?；?/strong>
Switch(config-if)#end
Switch#
Switch#show port-security address 查看地址表
Secure Mac Address Table
Vlan Mac Address Type Ports Remaining Age
(mins)
1 0002.4AA6.D46D SecureSticky FastEthernet0/1 -
1 0010.1108.D197 SecureSticky FastEthernet0/1 -
Total Addresses in System (excluding one mac per port) : 1
Max Addresses limit in System (excluding one mac per port) : 1024
验证试验，两台先接入的主机可以访问PC3 ，第三台不能访问PC3 说明试验成功 。
验证安全端口的另外一种模式-静态绑定
Switch#conf t
Switch(config)#
Switch(config)#interface f0/1
Switch(config-if)#no switchport port-security mac-address sticky 删除动态绑定
Switch(config-if)#do show port add
Secure Mac Address Table
Vlan Mac Address Type Ports Remaining Age
1 0002.4AA6.D46D SecureSticky FastEthernet0/1 -
动态绑定的地址还在
1 0010.1108.D197 SecureSticky FastEthernet0/1 -
Total Addresses in System (excluding one mac per port) : 1
Max Addresses limit in System (excluding one mac per port) : 1024
Switch(config-if)#end
Switch#clear port-security sticky
清除动态绑定地址
Switch#show port-security address
Secure Mac Address Table
Vlan Mac Address Type Ports Remaining Age
(mins)
Total Addresses in System (excluding one mac per port) : 0
Max Addresses limit in System (excluding one mac per port) : 1024
Switch#conf t
Switch(config)#interface f0/1
Switch(config-if)#switchport port-security mac-address 00D0.FF76.14ED 手动绑定PC的MAC
Switch(config-if)#switchport port-security mac-address 0010.1108.D197
PC的MAC地址需要你自己在pC 的命令提示符下获取，获取方法：ipconfig /all
验证试验，静态绑定的PC可以访问PC3 ，其他不可以访问PC3 ，证明试验成功 。
