Figure 5-5 Standby Command Configuration
The following abbreviations are appended to the switch host names in the 
Selected list to show their status in the standby group:
• AC—Active command switch
• SC—Standby command switch
• PC—Member of the standby group but not the standby command switch
• CC—Command switch when HSRP is disabled
The virtual IP address must be in the same subnet as the IP addresses of the 
switches, and the group number must be unique within the IP subnet. It can be 
from 0 to 255, and the default is 0.
The Standby Command Configuration window uses the default values for the 
preempt and name commands that you have set by using the CLI. If you use this 
window to create the HSRP group, all switches in the group have the preempt 
command enabled, and the name for the group is clustername_standby.
