What is the best/only way to create a job to reload several switches at once?
I was thinking to go to RME,config mgmt, netconfig jobs, and create and adhoc job that says reload. Is there a better option?
Yes and no. Go to Netconfig, and create an ad hoc job to deploy a "reload at" command. Assuming all of the switches have NTP, they will all reload at the exact same time. If you scheduled a Netconfig job to actually perform the reload operation, not all the switches would reload at exactly the same time.
