Switch SW1:
[SW1] BATCH VLAN 20 is 10 (creating multiple VLAN)
[SW1] int E0 / 0 /. 1 (access port)
[SW1-Ethernet0 / 0 /. 1] Port Link-type access (configuration port access mode)
[ sw1-Ethernet0 / 0/1] port default vlan 10 ( added VLAN10)
[SW1-Ethernet0 / 0 /. 1] int E0 / 0/2 (into the second port)
[SW1-Ethernet0 / 0/2] port Link- access type (access port configuration mode)
[SW1-Ethernet0 / 0/2] port 20 is default VLAN (VLAN20 added)
[sw1] port-group 1 (Create Group)
[SW1-Port-Group-. 1] Group-Member E0 / 0 /. 3 E0 / 0 /. 4 (the e / 0/0/3, e0 / 0/4 was added group )
[SW1. 1-port-Group-] port Link-type trunk (trunk configuration port mode)
[SW1. 1-port-Group-] port trunk vlan All the allow-pass (vlan tagged by allowing all)
[sw1]stp region-configuration （进入stp域的配置）
[sw1-mst-region]region-name+（名字） {设置名字，名字必须和其他的交换机设置的是一样，也必须要设置名字}
[sw1-mst-region]instance 1 vlan 10 （指定实例中的vlan）
[sw1-mst-region]instance 2 vlan 20 （指定实例中的vlan）
[sw1-mst-region]active region-configuration （激活stp域）
交换机sw2为vlan10的跟网桥，vlan20的次网桥：
[sw2]vlan batch 10 20
[sw2]int e0/0/1
[sw2-Ethernet0/0/1]port link-type access
[sw2-Ethernet0/0/1]port default vlan 10
[sw2-Ethernet0/0/1]int e0/0/2
[sw2-Ethernet0/0/2]port link-type access
[sw2-Ethernet0/0/2]port default vlan 20
[sw2]port-group 1
[sw2-port-group-1]group-member e0/0/3 e0/0/4
[sw2-port-group-1]port link-type trunk
[sw2-port-group-1]port trunk allow-pass vlan all
[sw2]stp region-configuration
[sw2-mst-region]region-name+（名字）
[sw2-mst-region]instance 1 vlan 10 （实例1）
[sw2-mst-region]instance 2 vlan 20 （实例2）
[sw2-mst-region]active region-configuration
[sw2]stp instance 1 priority 4096 （配置实例1为跟网桥）
[sw2]stp instance 2 priority 8192 （配置实例2为次网桥）
交换机sw3为vlan20跟网桥，vlan10为次网桥：
[sw3]vlan batch 10 20
[sw3]int e0/0/1
[sw3-Ethernet0/0/1]port link-type access
[sw3-Ethernet0/0/1]port default vlan 10
[sw3-Ethernet0/0/1]int e0/0/2
[sw3-Ethernet0/0/2]port link-type access
[sw3-Ethernet0/0/2]port default vlan 20
[sw3]port-group 1
[sw3-port-group-1]group-member e0/0/3 e0/0/4
[sw3-port-group-1]port link-type trunk
[sw3-port-group-1]port trunk allow-pass vlan all
[sw3]stp region-configuration
[sw3-mst-region]region-name+（名字）
[sw3-mst-region]instance 1 vlan 10 （实例1）
[sw3-mst-region]instance 2 vlan 20 （实例2）
[sw3-mst-region]active region-configuration
[sw3] stp instance 2 priority 4096 ( Configuration Example 2 with the bridge)
[SW3] STP instance 1 priority 8192 (for the second bridge configuration example 1)
Summary =
configured the software can capture, capture of data to look at the ping to either side.
