【實驗設備】:

交換機一臺

PC機一臺

直連網線一臺

【實驗內容】:

第一步: 配置交換機端口的最大連接數限制

S3750#configure terminal

S3750(config)#interface range fastethernet 0/1-23

S3750(config-if-range)#switchport port-security

S3750(config-if-range)#switchport port-secruity maximum 1

S3750(config-if-range)#switchport port-secruity violation shutdown

第二步:驗證 交換機端口的最大連接數限制

S3750#sh port-security

Secure Port MaxSecureAddr(count) CurrentAddr(count) Security Action

------------------------ -------------------- ------------------ ---------------

FastEthernet 0/1 1 0 Shutdown

FastEthernet 0/2 1 0 Shutdown

FastEthernet 0/3 1 0 Shutdown

FastEthernet 0/4 1 0 Shutdown

FastEthernet 0/5 1 0 Shutdown

FastEthernet 0/6 1 0 Shutdown

FastEthernet 0/7 1 0 Shutdown

FastEthernet 0/8 1 0 Shutdown

FastEthernet 0/9 1 0 Shutdown

FastEthernet 0/10 1 0 Shutdown

FastEthernet 0/11 1 0 Shutdown

FastEthernet 0/12 1 0 Shutdown

FastEthernet 0/13 1 0 Shutdown

FastEthernet 0/14 1 0 Shutdown

FastEthernet 0/15 1 0 Shutdown

FastEthernet 0/16 1 0 Shutdown

FastEthernet 0/17 1 0 Shutdown

FastEthernet 0/18 1 0 Shutdown

FastEthernet 0/19 1 0 Shutdown

FastEthernet 0/20 1 0 Shutdown

FastEthernet 0/21 1 0 Shutdown

FastEthernet 0/22 1 0 Shutdown

FastEthernet 0/23 1 0 Shutdown

S3750#show port-security interface fastEthernet 0/1

Interface : FastEthernet 0/1

Port Security : Enabled

Port status : up

Violation mode : Shutdown

Maximum MAC Addresses : 1

Total MAC Addresses : 0

Configured MAC Addresses : 0

Aging time : 0 mins

SecureStatic address aging : Disabled

第三步:配置交換機端口的MACIP地址綁定

查看主機的IPMAC地址信息

在主機上打開CMD命令提示符窗口,執行ipconfig /all命令

配置交換機端口的地址綁定

S3750#configure terminal

S3750(config)#interface fastethernet 0/3

S3750(config-if)#switchport port-security

S3750(config-if)#switchport port-security mac-address 0006.1bde.13b4 ip-address 172.16.1.55

第四步:查看地址安全綁定配置

S3750#sh port-security address all

Vlan Port Arp-Check Mac Address IP Address Type Remaining Age(mins)

---- ----------------------- ---------- -------------- --------------- ---------- -------------------

1 FastEthernet 0/3 Disabled 0006.1bde.13b4 172.16.1.55 Configured -

S3750#sh port-security address interface fa0/3

Vlan Mac Address IP Address Type Port Remaining Age(mins)

---- --------------- --------------- ---------- ----------------------- -------------------

1 0006.1bde.13b4 172.16.1.55 Configured FastEthernet 0/3 -

第五步:配置交換機端口的IP地址綁定

S3750(config)#int fastEthernet 0/2

S3750(config-if)#switchport port-security ip-address 10.1.1.1

S3750#show port-security address all

Vlan Port Arp-Check Mac Address IP Address Type Remaining Age(mins)

【實驗結果】:

給每個接口設置的最大接口數爲4

0/3接口綁定IP 172.28.15.6 MAC地址爲c89c.dc22.61c6

0/10接口綁定IP172.28.15.6
