The fix pulled from 15.19 is back, along with some other routing table and ARP fixes for issues that I'm pretty sure we've seen. Plan is to upgrade a number of L3 MS355 stacks next week...
Oddly, 15.20 no longer shows PoE information at the individual port or PSU level.
What switches have you seen that on?
I'm seeing this on MS220-48LP, MS320-48LP, MS220-8P so far.
I can confirm the same, even after a reboot, on an MS220-8p. @Ryan_Miles we have a problem...
I upgraded another network with MS210-48LP and MS225-48LP switches and they do correctly report PoE both in the switchport page and the power supply page. It looks like the bug is version specific and perhaps only for older models. I'll schedule in some other switch model upgrades so we can see more.
Power info is ok on my 120-8LP and 355. Anyone seeing an issue please open Support cases.
We've had to roll back to 15.19 because one MS320-48LP continued to reset PoE devices over and over.
We have an open case for the same MS320 that is warm-booting, so we'll add this note to that.

15.21 is supposed to contain the fix, not sure when it will be released though.
Completely avoiding this update. We have had two issues with two separate clients. One on ms320 other on ms350. MS320 it completely broke poe. Ms350 it completely broke stacking. After downgrading both from 15.20 back to 14.33.1, SFP is now broken. I know it says stable release candidate-- I'd suspect it never becomes an actual stable release.
We upgraded a stack of four MS355-48X switches this morning from 15.18/19 to this as 15.18/19 just wasn't stable. So far, so good with this release.
I do worry a bit about the issues with recent releases as they seem to randomly affect certain models and configurations...
PoE and stacking does work on the 355s.
Has anyone upgraded to 15.20 on stacked MS390s? If so, what has your experience been like? Specifically, I'm wondering about broken PoE or other major issues.
I still keep getting occasional amber connectivity light on my MS225-48LP 3 switch stack. Tech support suggested going to this version but seems there are still some gremlins.
Anyone have a suggested stable release firmware to run on the MS225-48LP?
We moved to this version and it broke multicast for my PA/CLOCK system. It broke it so bad the server that hangs off a Meraki switch could not talk via multicast to the speakers that were on the same switch. As soon as I rolled back to 14.38.1, the entire system came back up. Sounds like there are bugs in 15.20. Be careful.
@JeffreyB what switch models are you running it on? We have one VLAN that needs multicast to work for video feeds and it appears to be fine. In our case it is a stack of MS355-48Xs as the core with an MS210-48LP hanging off them.
@cmr - We're running MS355's on the edge, and Cisco 9500-16 as the core. The 355's are stacked. We moved equipment off the 355's and were able to communicate. When we rolled back, everything started functioning normally. We're going to stay at this release until this bug is addressed.
Hi. I´m about to upgrade a stacked pair of MS210 and a single MS210 connected through SFP fiber to one of the stacked members. The upgrade is necessary because Merki support incest it should be the latest version switch version after we run in to a problem with that switches lose dashboard connectivity for a few minutes after vi upgraded the Mx version (I know it sounds crazy). CRM you who worked a lot with the product. You have not had any issues with MS210 after update to 15.20? And I don´t see that we affected by the known problem of Cross-stack LACP bundles problem in our environment either.
