You need to select a switch that you want to be the master switch as the seed switch when you create the
Note
IOA cluster. If you have multiple switches in a site, you may add all the switches in a site that you want
to manage from to the cluster before adding the switches from the remote site.
In this example, the SJC site may be a natural consolidation point for management, and you may choose
Note
a switch from this site as the preferred master switch.
