Are you native IOSXE on the Cat 9300s or did you put them into Meraki with CS software?  I have a couple of Cat 9300s stacked and wedged between my MX pair and MS switches, but I'm using extended access lists on the Cat9300s because they are native. I would think going with Meraki CS on the Catalyst switches would allow you to use Group Policy on them, but don't know for sure.  ... View more

This is actually coming from the device itself, not from one of the sensors. If I click the device, I can get this graph with Alarms, Response Time Index, CPU Load Index and Traffic Index:     ... View more

I monitor my network with PRTG and have all of my MX and MS devices in there. One of the basic things I get for the devices are CPU, response time and a traffic index. There are other sensors for Netflow, etc. as well.   ... View more

Thanks, I usually do that. They make the reschedule easy to find, but the cancel options wasn't so obvious first time I dealt with this. I'd like to be able to opt out of that anything automatic, as I'm regularly looking for updates and evaluating.  ... View more

I have the same concern, as I'm working with my company to develop a change management process.  I get these once in a while, but I'm always (so far) able to reschedule them.  I can't imagine Cisco would ever force an update, but they don't really make it very clear how it can be cancelled.  It would be nice to be able to opt out of these, but I'm not aware of an ability to do that. ...

They are all MS220-8P and the only ones I have. They are older and we've had some issues like this with them before. I've got 5 stacks of MS355s, each with 6 to 8 switches, which updated smoothly. ... View more

The upgrade was pretty smooth for me overall. I updated a total of 43 switches for this site, models include MS425, MS355, MS120, MS220. Everything worked great (including one MS120) except for three MS220s I have, which basically all needed a factory reset and two of those needed to be goosed by support. I'm not sure the overall fix I was looking for is there, but I'll have to do some internal testing to verify.  I did not have the PoE issues others were wanting to address, so I can't speak to those. It's pretty stable, so I'll roll it to other sites soon. ... View more

What is doing routing between the two VLANs? (is the switch L3, have an MX or non-Meraki device?) You can create those VLANs and filter traffic with the switch ACL or Group Policy, but it would be important to know what is doing the routing. ... View more

I'll know Saturday night, as I'm pushing MS 16.8 to a good size site with MS425, MS355 and MS120 switches. I'll report here. 16.8 addresses a specific issue I'm having with LACP links. When I would reboot a stack in an IDF or even interrupt the trunk to our security appliance stack the core switches would go orange for 10 to 15 minutes.  ... View more

There are things you can do to address throughput. I would expect that losing connectivity to storage altogether (and any outage, nuisance or damage that may bring) is a bigger issue. I'd be curious to know how much throughput you'd lose. It's the same switches. Did they tell you about the drawback to the stack in the design, or was that an oversight? ... View more

What exactly happens to the VMWare hosts when you update the firmware on the stack? The whole stack will reboot, so the servers would be unavailable anyway.    Is there some issue with them recovering afterward?   I have a similar setup with an MS425 stack and 4-node VMWare cluster and do not have issues when updating switch firmware. ...

What specifically are you looking for? PRTG has a free license for up to 100 sensors. It has sensors for device health (CPU, memory, etc) and also supports SNMP sensors for port-level utilization, errors, etc. NetFlow is also supported. Their paid offering  is worth it as well. ... View more

In my case, OSPF would have been only to redistribute into BGP for my Cat93K pair and an ExpressRoute circuit (requiring BGP). That's why I bought Cat93K-Y switches. I needed a network core that could participate in BGP. A Meraki engineer who helped me verify my configuration said native BGP was coming to the MX eventually. I'm sticking with Cat93K at core and edge for now, so I have access to the protocols, etc I need. I love Meraki, but I'm running MS switches as access layer devices. ... View more

I run a pair of Cat93K-Y switches in our data center core and decided not to put them into the Meraki dashboard.  I'm still not clear on what I'd lose.  The design looks good to me. I have a similar situation, as the MX250 pair we have was doing all routing for the site.  I was going to use OSPF, but elected not to because there were limitations on the MX. I don't know if these are still there (It's been a year since I've checked), but I found that the MX would advertise OSPF routes, but not learn them.  I would recommend combing through the documentation to verify the MX in your plan. This is the doc that stopped me from using OSPF: Using OSPF to Advertise Remote VPN Subnets - Cisco Meraki Documentation   ... View more

I was able to cancel the upgrade. I was hesitant to apply it until I saw other people using it, so I scheduled it 30 days out. At first I thought all I could do was move the date, but figured out I could cancel it if I went to 'Organization' -> 'Firmware Upgrades' - 'Scheduled changes'. At that screen you will see the scheduled upgrade and will have the option to cancel. Once I did that, it was not pushed again.    I definitely agree they shouldn't be pushing an RC like this in the first place. They don't make it easy or intuitive to cancel. It would have been much better to have a 'Skip this upgrade' option or something in the first notice. If I want to be a test bed for Meraki, I'll go get the software myself. I don't need it done automatically. That's not a stable way to manage infrastructure.  ... View more

It does not sound like you have a device configured to route between these VLANs.  All you have laid out is layer 2 switching, but have not talked about what (if anything is setup to do routing). You would have to have a single device connected to all VLANs (either an MX or switch with L3 routing turned on). You cannot forward traffic between VLANs without a routing device connected to all VLANs That routing device would have an IP address in each VLAN, which would use as a default gateway on that VLAN.   Also as @PhilipDAth  says, all of those VLANs would have to be defined in each switch.  This is because the non-Meraki switches are not learning the VLAN from the Meraki network.    Is there a reason you have to cascade the switches, rather than have both Switch 2 and 3 connect directly to Switch 1?   What model is Switch 1? Is it Layer 3 capable, or do you have an MX? ... View more

Do you have any idea what firmware it had on it vs. the current level for the network it is plugged into? If it is far enough out, I could see it needing more than one pass at updating.  I don't know that for sure because I have not had to do that. ... View more

Thanks for the info.  I've found that you can reschedule the update for up to 30 days.  I received the first notification on 2/13 and rescheduled for 3/13. I went back on 2/16 and was able to reschedule for Saturday 3/16, so it looks like a sliding 30 day window.  I'm just going to keep moving the window until it is safe to install. ... View more
