一、搭建本次实验的拓扑环境两台核心，一台接入，一个上行
二 、配置SEP的基础信息1、配置SEP段信息[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 all2、配置SEP的接口信息[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 23、配置阻塞方式和抢占模式[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 304、配置拓扑变更通告[S1]sep segment 2 [S1-sep-segment2]tc-notify segment 1 [S2]sep segment 2 [S2-sep-segment2]tc-notify segment 1
三、验证SEP信息关闭SW1的G0/0/1端口，观察SEP信息[SW2]dis sep toSEP segment 1-----------------------------------------------------------------System Name Port Name Port Role Port Status-----------------------------------------------------------------SW1 GE0/0/1 primary forwardingSW2 GE0/0/1 common forwardingSW2 GE0/0/2 common discardingSW1 GE0/0/2 secondary forwardingSEP segment 2SEP detects a segment failure that may be caused by an incomplete topology-----------------------------------------------------------------System Name Port Name Port Role Port Status-----------------------------------------------------------------SW2 GE0/0/4 secondary forwardingSW3 GE0/0/2 common forwardingSW3 GE0/0/1 common discarding
五、验证smart Link的信息[S4]display smart-link group 1DeviceID: 5489-98ec-f012 Control-vlan ID: 100 Member Role State Flush Count Last-Flush-Time ---------------------------------------------------------------------- Ethernet0/0/14 Master Active 1 2008/01/05 03:11:18 UTC-05:13 Ethernet0/0/24 Slave Inactive 0 0000/00/00 00:00:00 UTC+00:00关闭SW4的G0/0/1观察SW4的smart Link信息
六、配置SEP与smart Link混合信息[S1]sep segment 1 [S1-sep-segment1]deal smart-link-flush [S2]sep segment 1 [S2-sep-segment1]deal smart-link-flush
七、查看设备信息，验证混合信息[SW1]dis sep toSEP segment 1-----------------------------------------------------------------System Name Port Name Port Role Port Status-----------------------------------------------------------------SW1 GE0/0/1 primary forwardingSW2 GE0/0/1 common forwardingSW2 GE0/0/2 common discardingSW1 GE0/0/2 secondary forwardingSEP segment 2SEP detects a segment failure that may be caused by an incomplete topology-----------------------------------------------------------------System Name Port Name Port Role Port Status-----------------------------------------------------------------SW1 GE0/0/4 secondary discarding
注意SEP的配置上行信息
注意smart Link配置的信息以及核心信息
