S21交换机（端口+IP+MAC）配置模板
S21交换机（端口+IP+MAC）配置模板：
IP+MAC+端口：
例：在端口F0/2上绑定：IP:192.168.12.202 MAC: 00d0.f800.073c的主机。
Switch# configure terminal
!进入全局配置模式
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface fastethernet 0/2
!进入端口2配置模式
Switch(config-if)# switchport mode access
!把端口模式改为access口
Switch(config-if)# switchport port-security
!启用端口安全
Switch(config-if)# switchport port-security maximum 24
!最多允许24个mac地址，最大128
Switch(config-if)# switchport port-security mac-address 00d0.f800.073c  
!端口和mac地址的绑定
Switch(config-if)# switchport port-security mac-address 00d0.f800.073c ip-address 192.168.12.202
!端口+mac地址+ip地址绑定
Switch(config-if)# end
