PoE Scheduling support for SR switches

The SR Switch Family provides excellent PoE support. Also scheduling support is within the HiveOS as well. Why not implement PoE schedules so that you can turn off PoE powered devices like phones, aps and so on during unused timeperiods like nights or weekends. Can also be used to trigger a reboot of devices for any reason appropriate.

We are already planning to implement an atomic "PoE bounce" function to force a reboot on downstream PoE equipment.

The idea of scheduling delivery of power to downstream devices is interesting from a green perspective, but honestly I doubt if it would be all that attractive to most of our current customers. My understanding and belief is that most (I'm tempted to say all) PoE equipment attached to us is considered network infrastructure and should always be on.

I'm willing to be persuaded otherwise, but I don't think the development and test effort would be worth the increase in sales we would see by offering this capability.

Coming from Meraki we have used that feature in about 70% of all deployments in SME businesses. The ability to save power and fully disable devices like APs has appealed to many of our customers, so I wouldn't exactly share that opinion.

Really? Okay, that's news to me. We have some overlap with Meraki customers, although I think we tend to win customers who value our feature set and flexibility more than their ease-of-use.

I don't own this particular feature in our product, so while I try my best to represent Aerohive here on the community site, my opinion is not always the final one. I'll make sure that the appropriate product manager sees this thread, and who knows, maybe you'll see this appear in a future release of our products.

Could you script this yourself as a workaround via SSH interaction?

Nick,

Thanks. At this point I'm not too familiar with SSH interaction. As this would need to be something automatic how would you do this? how could you define a script to run at a a given time on the switch?

You can typically locate the command sequence to enable or disable a port and write an Expect script to use it appropriately via SSH.

See: http://en.wikipedia.org/wiki/Expect

By scheduling execution of the script for the desired times of day, you can get ports enabled or disabled as you want them.

The script would run on a server and not on the switches themselves.

It is not as clean as having the switches do it themselves, but it is a possible workaround.

A caveat would be making changes to the configuration of the switches via HiveManager which would likely overwrite the port state with whatever is configured there.

Thank you Nick, but involving an external server would not work in mainstream smb deployments.
