　　检验和调试：

　　检验：

　　show standby [接口 [组]][active|init|listen|standby][brief]

　　如：

　　show standby Ethernet0 init brief

　　调试：

　　debug standby：显示所有的HSRP错误、事件和数据包

　　debug standby terse ：显示除hello和通告以外的所有HSRP错误、事件和数据包

　　debug standby events detail：显示HSRP事件

　　debug standby error：显示HSRP错误

　　debug standby packets [advertise|coup|hello|resign][detail]

　　案例：
