11.把PC接入到ED-SW的Fa0/2，并记录端口指示灯转换到绿色的时间___S
为了解决交换机端口转发延迟问题，启用Fa0/2的portfast功能
ed-sw（config-if）#spanning-treeportfast
%Warning:
portfastshouldonlybeenabledonportsconnectedtoasingle
host.Connectinghubs,concentrators,switches,bridges,etc...tothis
interfacewhenportfastisenabled,cancausetemporarybridgingloops.
UsewithCAUTION
%PortfasthasbeenconfiguredonFastEthernet0/2butwillonly
haveeffectwhentheinterfaceisinanon-trunkingmode.
注：
也可以在全局模式下输入spanning-treeportfastdefault启用所有的端口portfast功能
12.重新插拔PC与ED-SW的网线，再次记录端口指示灯转换到绿色的时间__S
验证portfast已经在Fa0/2口上启用
ed-sw#shspanning-treeinterfacef0/2portfast
VLAN0001enabled
13.配置PCIP地址：

14.在PC的DOS命令行下：
ping192.168.88.201-t
断掉ED-SW到Core1的连接，记录ping包丢失了___个
15.在ED-SW上配置uplinkfast
ed-sw（config）#spanning-treeuplinkfast
16.验证uplinkfast
ed-sw#shspanning-treeuplinkfast
UplinkFastisenabled
17.在PC的DOS命令行下：
断掉ED-SW到Core1的连接，记录ping包丢失了__个
18.取消ED-SW的uplinkfast功能
ed-sw（config）#nospanning-treeuplinkfast
19.启用Core1，Core2，ED-SW的RSTP功能
Core1，Core2，ED-SW：
（Config）#spanning-treemoderapid-pvst
20.验证RSTP是否启用

21.配置MST
Core1，Core2，ED-SW上启用两个MSTInstance1，2
Vlan1，3，5，7，9映射到Instance1
Vlan2，4，6，8，10映射到Instance2
Core1instance1优先级设为4096
