一、搭建本次实验的拓扑和环境要求电脑配置：4G内存，cpu性能至少2.3GHZ，双线程更好eNSP：4台交换机，两台S5700、两台S3700，有真实的机器更好，土豪
三、创建SEP段并配置控制VLAN和指定保护实例[S1]sep segment 1 [S1-sep-segment1]control-vlan 10 [S1-sep-segment1]protected-instance all [S1-sep-segment1]quit [S1]sep segment 2 [S1-sep-segment2]control-vlan 20 [S1-sep-segment2]protected-instance all [S2]sep segment 1 [S2-sep-segment1]control-vlan 10 [S2-sep-segment1]protected-instance all [S2-sep-segment1]quit [S2]sep segment 2 [S2-sep-segment2]control-vlan 20 [S2-sep-segment2]protected-instance all [S3]sep segment 2 [S3-sep-segment2]control-vlan 20 [S3-sep-segment2]protected-instance all [S4]sep segment 2 [S4-sep-segment2]control-vlan 20 [S4-sep-segment2]protected-instance all
四、将接口加入SEP段，并配置接口角色[S1]interface GigabitEthernet 0/0/9 [S1-GigabitEthernet0/0/9]stp disable [S1-GigabitEthernet0/0/9]sep segment 1 edge primary [S1-GigabitEthernet0/0/9]inter GigabitEthernet 0/0/10 [S1-GigabitEthernet0/0/10]stp disable [S1-GigabitEthernet0/0/10]sep segment 1 edge secondary [S1-GigabitEthernet0/0/10]inter GigabitEthernet 0/0/13 [S1-GigabitEthernet0/0/13]stp disable [S1-GigabitEthernet0/0/13]sep segment 2 edge primary [S2]interface GigabitEthernet 0/0/23 [S2-GigabitEthernet0/0/23]stp disable [S2-GigabitEthernet0/0/23]sep segment 2 edge secondary [S2-GigabitEthernet0/0/23]inter GigabitEthernet 0/0/9 [S2-GigabitEthernet0/0/9]stp disable [S2-GigabitEthernet0/0/9]sep segment 1 [S2-GigabitEthernet0/0/9]inter GigabitEthernet 0/0/10 [S2-GigabitEthernet0/0/10]stp disable [S2-GigabitEthernet0/0/10]sep segment 1 [S3]interface Ethernet 0/0/13 [S3-Ethernet0/0/13]stp disable [S3-Ethernet0/0/13]sep segment 2 [S3-Ethernet0/0/13]inter ethernet 0/0/23 [S3-Ethernet0/0/23]stp disable [S3-Ethernet0/0/23]sep segment 2
五、配置阻塞模式和抢占模式[S1]sep segment 1 [S1-sep-segment1]block port optimal [S1-sep-segment1]quit [S1]sep segment 2 [S1-sep-segment2]block port [S1-sep-segment2]block port optimal [S2]interface GigabitEthernet 0/0/10 [S2-GigabitEthernet0/0/10]sep segment 1 priority 128 [S3]inter Ethernet 0/0/23 [S3-Ethernet0/0/23]sep segment 2 priority 128 [S1]sep segment 1 [S1-sep-segment1]preempt delay 30 [S1-sep-segment1]quit [S1]sep segment 2 [S1-sep-segment2]preempt delay 30
六、配置拓扑变更报告[S1]sep segment 2 [S1-sep-segment2]tc-notify segment 1 [S2]sep segment 2 [S2-sep-segment2]tc-notify segment 1
七、验证SEP的作用1、查看SEP运行信息2、关闭S2的G0/0/9端口查看SEP运行情况3、打开S2的G0/0/9端口，关闭S3的E0/0/13端口并查看SEP运行情况4、打开S3的E0/0/13端口，查看运行情况
注意交换机的端口信息变化
注意软件的安装，是否正常，再进行虚拟机测试
