Save ? [yes/no]: yesBuilding configuration...[OK]This will reload the active unit and force switchover to standby[confirm]执行重启后原来的standby会成为Active:C1-SVR1-CS1#show switch virtualSwitch mode : Virtual SwitchVirtual switch domain number : 100Local switch number : 2Local switch operational role: Virtual Switch ActivePeer switch number : 1Peer switch operational role : Virtual Switch Standby第1台设备重启完毕后再执行相同的命令重启第2台设备.C1-SVR1-CS1#redundancy force-switchover System configuration has been modified. Save ? [yes/no]: yesBuilding configuration...[OK]This will reload the active unit and force switchover to standby[confirm]如何确认设备已重启完成？通过查看VSS冗余状态可以看到，当显示为standy HOT，表示2台设备已同步成功。C1-SVR1-CS1#show redundancy states my state = 13 -ACTIVE peer state = 8 -STANDBY HOT Mode = Duplex Unit = Primary Unit ID = 37注意:如果执行reload命令，则会导
