Most of my networks got this scheduled as well. Odd since their website still lists this as RC. Time to reschedule them back a month and see.
Yea stable is still listed as 10.45. 11.22 was shown on as being released on June 14th. I'm going to let it stew in the wild a bit longer I think. The other thing is that we are closed on Thursday/Friday for Independence Day. My upgrade is scheduled for 7/7 at 00:04 (am). I'd rather not have to think about this on my 4 day weekend. If I push it back two weeks and there's no further version upgrade it will have been in the wild for 5 weeks roughly. I'm pretty comfortable with that.
Probably a wise choice to hold off. I asked my boss if he had seen any issues with Meraki firmware upgrades in the past since this was my first time dealing with Meraki firmware upgrades. He said he hadn't seen any with the two he was involved with so I let the upgrade to MS 11.22 go through on 7/7.
Early in the week, I had some people tell me about some issues they were having with mapped drives disconnecting and I got disconnected from an Access database on a network share multiple times. After some investigating, I found that some packets to VLAN interfaces on the MS 250 stacks at each of our office appeared to intermittently drop. Pinging from a host to its gateway on the MS 250 stacks would be successful for a while then would start dropping for minutes at a time. This was happening with multiple VLANs while some others were unaffected. Meraki support looked things over but couldn't find a reason for it. At their request, I rebooted both switches in the stack at one of our offices to see if that would resolve the issue but it didn't.
I rolled back the firmware on 7/14 and so far everything appears to be functioning correctly again.
Yuck. I can't be having packet drops. Was it a particular VLAN or was it random?
I pushed my upgrade back again, to the first weekend in August. I might push it back again after that. 11.22 is now shown as the stable version on that same page I posted above though.
There were at least 3 or 4 VLANs experiencing the issue across 2 different sites and switch stacks. I checked a handful of others but those seemed to be stable. Meraki support asked me to do a packet capture of pings from a server on one of the affected VLANs to its gateway. I sent that over to them last week but I haven't heard anything back yet.
@GregasGYes, as far as I could tell that's where we were having our issues. Meraki support did a packet capture when I was on the call with them last week and I believe they told me they could see the pings coming in from one of our servers but they weren't seeing any reply going back out.
I have got 9 Networks updated to MS11.22, no issues, this are smaller networks up to 9 switches MS225, MS220, MS210 .
4 Networks are running on MS11.23, no issues, this are smaller networks up to 4 switches.
Our main network ist still running with MS10.45 with 33 MS 225 and MS220 switches.
