Creating a Switch Cluster

Designating and Enabling Standby Command Switches

To create a standby group, display Cluster Manager, and select Cluster >
Standby Command Configuration to display the Standby Command
Configuration window (Figure 5-5).
Eligible switches are listed in the Candidates list according to an eligibility
ranking. Candidate switches are ranked first by the number of links they have and
second by the switch speed. If the switches have the same number of links and
speed, they are listed alphabetically.
In the Selected list, the active command switch has the highest priority and is
always at the top of the list. The standby switch with the next highest priority
becomes the standby command switch. The standby command switch is listed
after the active command switch, followed by the other standby switches
according to their priority. The last switch has the lowest priority. If the primary
command switch fails, the standby command switch becomes the primary
command switch. The standby switch with the next highest priority then becomes
the standby command switch.
