Hi Ivan,   Nope, it's 47.2W. Please find the sample output below. Is this normal? I mean, the AP is overconsuming above than the stated wattage on the device manual?   I do not think spanning tree is shutting ports, since the port is not disabled. Only the device is going down the up again. I have checked, my switch is configured in power sharing.   I only connect 1 LAN into the MR57 AP. So I do not have aggregation towards the AP in my deployment.   ... View more

Hi Rob,   however, are they poe+ or UPOE 3850's are the AP's showing they are pulling the full 30 watts? -> Yeap, in fact they are pulling 47.2W for each APs. is CDP enabled? -> CDP and LLDP are enabled Is the IOS on the 3850's somewhat updated? -> I am running 16.12.10a for all of my switches. The latest recommended version is 16.12.12, so not far behind. are the MR57's in the portal showing low power mode? -> Nope, no warning on the portal. I would also see if you can pull any events from the switch(s). -> Below are the logs on the related to the corresponding port.    ... View more

Hi Rob,   This starts after I added MR57s. Previously with Cisco 3802, I did not get issue like this.   Does the switch have any power saving options enabled where it would shut down devices? -> May I know how to check this? Are you running out of POE budget on the switch? -> Nope, only 10-15% of the total power budget are consumed. ... View more

Hi rwiesmann,   Change the switchport -> Okay will try this. Currently happens to many APs across different switches. If possible on a switch port on an other switch -> I think we can exclude this as happened to different switches already. Then change cables -> The cables are newly installed. Passed the fluke test as well. i would open a support case with cisco -> Will try this as well ... View more

Hi Vivek,   Are you using 1 or 2 LAN connection? The issue happened to around 40s of total 120s AP in my deployment. Everyday different AP experiencing the issue. ... View more

Well, the SFPs are sitting in a storage, still sealed. I know still more than 5 years old, but trying to see my available options for my future network project. Thank you Philip for raising your concern regarding the age of the device itself. ... View more

Thank you for you answer Shubh. I am planning to use 9300 Meraki switches. I see they offer 10Gig network modules, so I guess I'm good to go. ... View more
