That's not uncommon and typically represents the occasional missed ping response back from google public DNS, the MX will check health stats and run continuous pings every second to 8.8.8.8. I see the same in my own home lab MX64, see attached image. They could prove this out by running a packet capture on an upstream device and filter by host IP and icmp protocol to confirm there might be an occasional echo-reply packet lost. They can also go into the Security Appliance > Traffic Shaping page and add another destination IP address besides the default 8.8.8.8 and perhaps something closer upstream, maybe their ISP's DNS server, to get better results showing zero or close to zero loss. Then, on the Uplinks tab they can select between multiple destinations for connectivity status.

Thanks @PhilipDAth and @WadeAlsup appreciate the shout out. Correct, the Meraki employees won't be eligible for Meraki swag (although I wouldn't turn it down if @CarolineS sent me some, haha). We're all just happy to contribute and excited to see how great the Meraki Community is taking off! Keep up the great contributions and collaboration everyone!

I'm won't exactly chime in @WadeAlsup with anything exciting except to say do keep making wishes, hanging in there, and make it known to your Meraki or Meraki Partner reps so feature requests can be prioritized accordingly.

Hi @Bovie2K, As @MilesMeraki stated, there does not seem to be a hard limit, I do not believe the Z3 is artificially throttled to 100Mbps in firmware. You'd have to test to confirm, I don't have a Z3 at the moment to test with, just my Z1. The Z1 is rated for 50Mbps FW and 10Mbps VPN, while the Z3 is rated to 100Mbps FW and 50Mbps VPN. I just tested my Z1 and got 125Mbps through it with a handful of L7 FW rules in place. And the limiting factor there is my ISP, not the Z1. So the Z1 definitely wasn't capped at the spec of 50Mbps, and the Z3 likely shouldn't be either. While the Z3 has the much better specs versus the Z1, including 2x2 11ac W2 and 802.1X, both Z1 and Z3 still have the 5 recommended clients. While I believe (and have seen) the Z3 handle many more, ~5 clients is still the recommendation as it's more of a SOHO gateway.

Chances are this is usually a cable issue, so have extra patch cables when you go visit the site. Open a case with Meraki Support as well, they will be able to access lower level details in the logs that could shed more light on the issue, in case it turns out to not be cabling but as issue on the cable modem itself. If you have access to the online ISP account, send a reset signal to the cable modem or call their support line to have them also troubleshoot and/or reset the cable modem, or just wait until you're on site and reboot it. First things first though, I'd start by replacing the patch cable, rebooting the MR18, and rebooting the cable modem, then it's a wait-and-see game while you have Support investigate further. Good luck.

Check your SSID settings on the "Access Control" page, if you are using any type of splash page, and if so, there could be a setting for Network Access Control that's enabled to check clients for AV software that you would want to disable. If you are running the SSID wide open with no splash page and in NAT mode with no content filtering, then something further upstream must be redirecting the clients to the AV scan other than the MR33.

You would have to use the local status and configuration page on the access point, under the configuration tab, to have the Meraki AP itself communicate through the proxy.

Hi @AlvinJ yes I have had a wireless mesh network with more than 1 hop (2 mesh hops) and it worked fine. Always follow the rule of thumb to wire when you can, only mesh when you must, and because of the performance impact try to keep it to 1 mesh hop when possible. Two mesh hops (and even more) will still work, but with a significant drop in performance for each additional hop, so you need to take a close look at the number of clients and what type of apps they're running to determine if it will still be usable with the 3 hops you have depicted below. I don't believe there is a published limit, but that certainly does not mean there's no limit, although Aironet specifies 8 mesh hops max, you'd never want to do that either. I've deployed Aironet with 2 mesh hops as well but never 3 or more, if more than 3 consecutive mesh hops are required, most customers will look for another way to get more intermediate wired APs. Hope that helps!

Unfortunately MS configuration templates only work with L2 deployments today, so that's why you're not seeing the "Routing and DHCP" configuration option when the switches are bound to a template. https://documentation.meraki.com/MS/Deployment_Guides/Switch_Templates_Deployment_Guide_(CVD)

Not without some work. Aside from adjusting the number of results (1/5/10/etc) and specifying date/time ranges, unfortunately the Summary Reports page layout cannot be customized at this time the way you described, to be able to drag around or re-size different portions of it. But keep the wishes and use cases coming and feed these back through your Meraki or Partner reps to get back to the Dashboard team. One other quick thought might be to tag certain devices and then you can narrow the summary report more specifically by those tagged devices, but that's still not going to allow the page output to be rearranged in specific ways. One possibility may be to leverage the API to build your own customized Dashboard of sorts. More API info here: https://documentation.meraki.com/zGeneral_Administration/Other_Topics/The_Cisco_Meraki_Dashboard_API and http://developers.meraki.com/tagged/Dashboard and on developers.meraki.com in general. There's also a "Developers and APIs" room here in the Meraki Community to assist with getting started.

The Meraki License has expired. Go to Organization > License Info in your Dashboard organization, you'll be able to see any license(s) that were applied to the organization, when they were applied and how long they were good for. There is always a 1:1 relationship between a piece of Meraki hardware and the cloud license. The license is required, and is all-inclusive so it gives you access to configure and maintain the equipment, 24x7 access to support, access to all new firmware and feature updates, 1 year warranty on your outdoor APs (lifetime on indoor APs) and advance hardware replacement for RMAs. Licenses come in 1/3/5/7/10 year terms. You should have received LOTS of Dashboard banners and email warnings to all organization admins as the license expiration was approaching, and when the license actually expires there is a 30 day grace period (during which time there's a bunch more Dashboard banners and alert emails) and then eventually the devices get moved to a shutdown network and won't pass Internet traffic which is why you cannot access web sites through those APs. Your configurations should still be there so once the licensing state is restored it'll all come back up as before. When you buy a pair of AP licenses for your 2 MR66s, you'll just go to the License Info page, add a new license, and select the "renew my dashboard license" option. Hope that helps!

While I believe an updated version of the MX Sizing Guide is in the works and not released quite yet but should be any day now, for your 10, 20 and 50 site cases with 180, 760 and 4900 VPN tunnels, your appropriate current MX models should be MX100, MX250 and MX450 respectively.

Not supported. If you go (in the mobile dashboard app) to the "Switches" page you'll see a little "+" in the upper right and if you click that you'll then see the barcode icon to add a new switch by scanning another switches barcode to whichever switch network you're in at that time. Same goes for wireless APs. But MX networks only have a single MX in them (unless you're running warm spare HA then there's two) but still only a single "active" MX in any given network, so no "+" sign with a barcode tool behind it. In the place where you might expect the "+" sign it'll actually be a pencil icon to change its name or add tags. What you might want to look at is the Bulk Network Configuration tool under the Organization tab. You can choose your source configuration if you already have an MX network or template defined, and have your 200 MX65W appliances listed out in a CSV file along with their names, networks, serial numbers, addressing info, etc. More on that here: https://documentation.meraki.com/zGeneral_Administration/Templates_and_Config_Sync/Using_the_Bulk_Network_Creation_Tool You can also then leverage configuration templates to make mass changes to those MX65Ws as a group. More on that here https://documentation.meraki.com/zGeneral_Administration/Templates_and_Config_Sync/Managing_Multiple_Networks_with_Configuration_Templates And if it's simply 200+ additions to your Dashboard inventory, you should be able to do that with the claim button on the Organization > Inventory page using one or more order numbers or serial numbers.

Agreed let's open a ticket to confirm and they'll have deeper visibility and can confirm the timeout period. I believe the devices will always proceed through their "normal/preferred" method of establishing cloud connectivity. There's no way to alter that via Dashboard or the local status/config page, so I don't believe there's a way to force it to use 80/443 by default, that's always going to be considered the backup connection.

Usually it's plug and play since almost every firewall rule is going to be outbound in nature, unless there's a restrictive firewall ruleset that even blocks outbound traffic. If outbound UDP/7351 to the Meraki data centers is blocked, that's the primary Meraki Cloud Communications mechanism, and with that blocked the devices (if they're up an running normally) should have fallen back to ports 80/443 to establish a backup cloud controller connection. Was the AP previously up and running normally using the primary cloud connection and subsequently UDP/7351 was blocked? I'd consider rebooting the AP and allowing it to proceed through its normal connectivity and health checks to see if it is in fact using the backup cloud connection. Also run a packet capture on the wired side of the AP and look for traffic on UDP/7351 for example and see if it's matched by any return traffic, as opposed to seeing traffic on 80/443 between the AP and the destination IPs on your FW rules page. If the weirdness continues, open a ticket with Meraki Support, they'll have some lower level visibility into the pass/fail state of specific firewall tests. Hope that helps!

All correct replies, more often than not this points to a physical layer issue, and I'd also suggest opening a ticket with Meraki Support and this will likely be the first thing they troubleshoot, I'd suggest a support ticket because they can have deeper troubleshooting visibility than would be visible in your Dashboard. Another good suggestion by @JPena was checking the firmware version, go to your Organization > Firmware Upgrades page not only to see what your running, but look through the release notes for your specific AP models and firmware rev (plus previous revs) to see if anything applies. There were some mesh/repeater issues and other general stability/performance improvements specific to mesh/repeater functions over the last year, I think mostly back in the earlier 24.X versions. But even if nothing shows up in the release notes, still worth checking with Support who may have more details than what's in the release notes and change log. Firmware fixes may have more to do with actual mesh/repeater operations, perhaps not what is causing your APs to sporadically fall into repeater mode, which brings us back to checking those L1 issues with cabling, patch panels, and any power injectors first. Ring out those cables with the cable test button (since it's a Meraki switch) but also with an external TDR cable tester if you have one. Also, if not enabled already, you can enable alerts anytime a gateway AP becomes a repeater AP under Network Wide > Alerts.

Ok perhaps you mean a 10GBaseT connection, meaning the server has a 10GBaseT copper RJ45 LAN connector? Meraki does not make a 10GBaseT SFP+ module. These are not common in the industry. 10GBaseT does consume more power (runs hotter) and has higher latency than using copper twinax direct attach cables or optical modules, so I think it'll be much more common to connect servers via direct attach cables (or optics). You might be able to use a 3rd party 10GBaseT SFP-10G-T SFP+ module since Meraki does not lock out non-Meraki SFPs, but I don't think it would not be officially supported. Or perhaps another option is a 3rd party 10GBaseT copper to fiber media converter, and connect your server via Cat6/7 to the RJ45 port and use a Meraki direct attach cable like MA-CBL-TA-1M to connect between the media converter and MS425.

Agree with @PhilipDAth and @WadeAlsup that if replacing the MX60 with an MX64 and all is well now, and perhaps you were loooking to re-deploy the MX60 elsewhere, if the appliance will still boot and come online, place it in a test network and open a Support ticket for them to take an in-depth look at its health/status. If it won't even boot, or is otherwise in need of an RMA, it's covered by the lifetime warranty.

I've done testing at home with a few devices with different capabilities (1x1 smartphone, 2x2 tablet, 3x3 laptop) with the (slightly older) MR72, with both omni and patch antennas. With omnis, the smartphone lost its connectivity first (in my case maybe around 75 meters), then the tablet as I approached the 100 meter mark, and lastly the laptop when I was probably over 125 meters away and connectivity got sporadic. So yes, I could get 100 meters and still have a usable experience (except with the smartphone) and obviously at lower data rates. It's definitely a "your mileage may vary" type of thing as that support doc describes. If you'll have several users and they'll be out there at 100+ meters, consider the ANT-25. It'll depend a lot on your use case, coverage pattern, client devices and client density, etc. Site survey is best bet, as @PhilipDAth mentioned 30 meter spacing, that may work well, and you'll know for sure with a site survey, even if something basic like using the local status page for some live readings on multiple types of devices. I've seen some deployments ranging even over 100m spacing also work well with omnis and without coverage holes.

That is correct, it's fairly standard to use 5GHz as the backhaul link and 2.4GHz to serve clients. And if you're going to have a lot of those mesh repeater APs you might consider the MR74, better suited for that purpose, since the MR84 is a dual-band 4x4 AP, where the MR74 is dual band 2x2 so it's all you need to have a 5GHz backhaul/mesh link and 2.4GHz omnis serving local clients. Just try to follow the rule of wired connections for as many APs as possible - wired when you can, mesh repeater only when you must., and try to keep the mesh link to 1 wireless mesh hop if possible, try to avoid 2+ wireless mesh hops, since every repeater roughly cuts performance in half. Are you working with a Meraki sales team or Partner sales team? There's a lot of planning for outdoor mesh, so I'd suggest reviewing some of the docs, if you simply go to the documentation and do a search on "mesh" you'll see about a half-dozen short articles to review. Check here: https://documentation.meraki.com/Special:Search?path=&q=mesh Hope that helps!

I think I might understand, you're asking for 10G copper (electrical) modules as opposed to fiber (optical) modules. For 10G copper/electrical, also called TwinAx, your options are the 1 meter and 3 meter "direct attach" cables to attach to servers. Those would be MA-CBL-TA-1M and MA-CBL-TA-3M. See "Direct Attach" in this data sheet: https://meraki.cisco.com/lib/pdf/meraki_datasheet_sfp.pdf

You can connect the ANT-27 for either frequency, ANT-27 is a dual band sector. On the MR74, 2 ports are for the 2x2:2 2.4GHz radio and the other 2 ports are for the 5GHz 2x2:2 radio. So just make sure you're plugging the ANT-27 into the 2 ports on the SAME side of the AP. Even though the ANT-27 is dual-band, you'll basically be using it as a band-specific sector antenna, because on the MR74, the antenna ports are single band, two for 2.4 GHz and two for 5 GHz. So you would use 2 ANT-27 antennas per MR74 AP to provide the dual-band coverage.

Yes, it should be a firmware limitation of 128 clients per radio, so 256 clients per AP. Note that is far beyond the number of clients that SHOULD be simultaneously connected to have anything resembling an acceptable user experience, because none of the wireless users will be happy when there's 200+ clients on a single AP. It's not really a hardware limitation so much, it's really just physics. So while 128 clients per radio may be an arbitrary firmware limit, that's beyond the practical / usable limit anyway.

Correct, functionally equivalent. The closest thing to the MS220-8 is the MS120-8 and the closest thing to the MS220-8P is the MS120-8FP. There's also the MS120-8LP for less PoE needs, 67W versus 124W on the FP. The MS120 compact models are less expensive than their MS220 counterparts so that's nice. It's newer hardware/chipsets of course, and better MTBF numbers on the 120 models. Pretty much the same horsepower, and line rate on every port, with 20Gbps (15Mpps) capacity, and larger port buffers on the 120-8 than the 220-8. To your other question, I'd say no, on this level of switch, you likely don't need 16K MAC entries (MS220-8 had 8K) and if you need that many MAC entries you're probably deploying higher models, but there are some use cases (maybe corner cases) where it could scale like that on the compact switches. Also remember MS120 is strictly L2 only, no L3 interfaces or static routes.
