华为eNSP配置SEP实验
1、一、搭建本次实验的拓扑和环境要求
电脑配置：4G内存，cpu性能常墨至少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
2、二、配置交换机的信息和各个接口没盲裹信息
<Quidway>system-view
Enter system view, return user view with Ctrl+Z.
[Quidway]sysname S1
[S1]
<Quidway>system-view
Enter system view, return user view with Ctrl+Z.
[Quidway]sysname S2
[S2]
<Quidway>瞧罪system-view
Enter system view, return user view with Ctrl+Z.
[Quidway]sysname S3
[S3]
<Quidway>system-view
Enter system view, return user view with Ctrl+Z.
[Quidway]sysname S4
3、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
4、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
5、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
6、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
7、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
