配置MSTP（优化功能）

S3500A(config)# spanning-tree mst configuration S3500A(config)#revision 5 S3500A(config)#name region 1

S3500A(config-mst)#instance 1 vlan 10 S3500A(config-mst)#instance 2 vlan 20 S3500A(config-mst)#exit

S3500A(config)#spanning-tree mst 1 root primary/priotity 0 //设置此交换机为instance1的生成树根

S3500A(config)#spanning-tree mst 2 root secondary/priotity 4096 //设置此交换机是instance2的生成树备份根 S2900配置

配vtp,TRUNK,vlan

S2900(config)#vtp mode client Setting device to VTP CLIENT mode. S2900(config)#vtp domain server

S2900(config-if)#switchport mode trunk S2900(config)#int f0/1

S2900(config-if)#switchport mode trunk

配置MSTP

S2900(config)# spanning-tree mst configuration S2900(config)#revision 5 S2900(config)#name region 1

S2900(config-mst)#instance 1 vlan 10 S2900(config-mst)#instance 2 vlan 20 S2900(config-mst)#exit 配置端口安全

S2900(config-if)#int f3/1

S2900(config-if)#switchport port-security maximum 2 S2900(config-if)#switchport port-security violation shut
