请教有关思科设备主备引擎切换测试的问题

[复制链接]

1台N7K和1台ASR1006,因为都是使用了几年的老设备了,现在用户希望能在不影响业务的情况下,测试下设备的主备引擎切换功能是否正常。
我查了下命令,有说使用redundancy force-switchover命令,使主引擎down掉,从而强制进行主备引擎切换,但我不清楚这样做是不是相当于把主引擎关掉啊?要还原为成原来的主引擎Active,备用引擎Standby该怎么做啊?
也看到说使用system switchover命令强制“Standby” 状态转换成 “Active” 状态,但这样貌似由不能测试主引擎挂掉后,备用引擎是否是自动切换的。所以希望有大神能指导下,谢谢了。两台设备的准备引擎状态如下:
N7K的主备引擎状态:
N7K# show redundancy status
Redundancy mode
---------------
      administrative:   HA
         operational:   HA

This supervisor (sup-5)
-----------------------
    Redundancy state:   Active
    Supervisor state:   Active
      Internal state:   Active with HA standby

Other supervisor (sup-6)
------------------------
    Redundancy state:   Standby

    Supervisor state:   HA standby
      Internal state:   HA standby

System start time:          Mon Jan  6 22:00:26 2014

System uptime:              1592 days, 0 hours, 25 minutes, 22 seconds
Kernel uptime:              1592 days, 0 hours, 29 minutes, 56 seconds
Active supervisor uptime:   1592 days, 0 hours, 25 minutes, 22 seconds


ASR1006的主备引擎状态:
ASR1006#show redundancy
