Catalyst 9300L PoE Strangeness

I've recently deployed a handful of Catalyst 9300L's and they're having some odd PoE issues which I've not seen on any of our MS switches. Firstly, the switches are denying PoE to new devices when total PoE consumption is at only 14% and total budget is at 50%.

 

Secondly, the switches are only giving devices a fraction of the power they're requesting, even when giving them full power would not exceed (or come close to) budget. For example, a range of high end security cameras requesting 30W are only being allocated around 6W or less by the switch.

 

I should note that we are managing these with Meraki dashboard and they are currently on CS 17.1.4

 

Maybe this is normal behaviour and I'm just not educated enough on using Catalyst switches via Meraki, but it seems unusual to me.

The device connected to the port won't always consume its full power; it will depend on the features being used. However, you are indeed experiencing strange behavior.

In this case, I suggest you update to the latest stable version, and if the problem persists, it's best to open a support case.

I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.
