Ours self-reported an outage from 7:00-7:35 A.M. EDT. Meh... *mumbles something about more coffee...*

Same chatter on Reddit. Users on reddit report that, it could look like Meraki outage happened at the same time as a Level3 outage. Meraki might use Level3 somewhere.

Being based in Denmark, ours are usually shipped from the Netherlands (Or Belgium, can't remember exactly but from the area).

I have a DMZ setting on my home router. From what I understand, when enabling this, and setting the DMZ address, what ever client with that address is in the DMZ of my home router and therefore free of any firewalling. I couldn’t get my MX to register in the cloud, and a call to my friendly neighbourhood ISP, confirmed my suspicion. My MX was being firewalled, even though it was put in DMZ. And this was working by design. So, take a look at your DLink, and verify it isn’t firewalling your MX. And afterwards try adding the Meraki Firewall info, that is required for Cloud communication.

Copy/paste into your favorite spreadsheet editor usually works for me (Excel). Things are nicely formatted. I haven't tried with the list of firmware versions, though. But I'd assume it's the same.

From what I'm told, they are not being discontinued. Quite to the contrary. They are just out-of-stock due to the high demand. We were given an expected ship date some time in august, but we managed to convince our Meraki AM to find one and ship very soon. Especially since we were promised that the one we could get instead in the meantime was in stock, but wasn't in stock afterall. It arrived today.

I would like to test deploying a medium size network using APIs, but getting multiple Z3s just to prove the concept seems to be a rather bad idea 😉 Any thoughts? Otherwise if you have a Cisco Account, you might be able to access the Cisco dCloud Meraki Demo for Partners. You won't get configuration access nor API access, but you'll be able to access a Full Stack Meraki and all topology configurations. It's primarily meant as a demo tool for partners towards end costumers. https://dcloud2-lon.cisco.com/content/instantdemo/cisco-meraki-launchpad-v1-instant-demo-partner?returnPathTitleKey=content-view&isLoggingIn=true

Thank you, and @PhilipDAth aswell. 🙂 It wasn't to much the switch specs, but more, which ports are GbE and which are MGig. Then I can make sure the technician onsite cables things correctly. 🙂

rhbirkelund · ‎Jun 14 2019

Hey, I'm preparing a configuration for an MS355-48X2 switch, which is the first one I've worked with. Does anyone else have one, who might help me with how ports are distributed on the frontpanel? What port(numbers) are GbE? mGig?

I have tried changing the port the AP is connected to in access of trunk mode. I have tried turning VLAN tagging on but I wasn't too sure which VLAN(s) to add to it - should it be the client VLAN, the server VLAN or both? Many thanks, Phil If you're getting errors from 10.128.128.128, you are still using Meraki DHCP. You sure it's in Bridge Mode? Did you check the correct SSID?

rhbirkelund · ‎Jun 5 2019

Are you using a local DHCP server or Meraki DHCP on the SSID? Is the AP connected to a switchport in trunk mode, or access mode? Is VLAN tagging enabled?

@Aaron_Wilson wrote: I feel like we have taken a step backwards with the MX67/68. You can't shut a port, no port security, etc. When you shut the port, does it still forward traffic? Can you do a packet capture on the LAN side of the MX? Does your equipment downstream lose connectivity to the internet? If so, It's either just a question of GUI implementation, that the green icon, doesn't go grey, or maybe that the port is shut, but PoE is still being provided. Whether the latter is a feature or bug, is up to the user, I'd suppose. For switches, you can shut a port, but still provide PoE on it.

Maybe try using SSL tester to make sure it isn't something dumb like a weak hash for weak cipher is being used. https://www.ssllabs.com/ssltest/ From what I know of, Letsencrypt is trusted by all major Root CAs. So in principle it should be secure enough. On the other hand, I remember to have read somewhere that many don't see Letsencrypt as a safe free encryption body any more, due to its ease in creating SSL certificates. Before, you could trust that if someone uses HTTPS the website was regarded as safe/free of malicious software, because certificates weren't easy to get, and people trusted it. With Letsencrypt, it has become too easy for malicious entities to create websites, even using Letsencrypt.

@kYutobi wrote: @jdsilva I think you also need a CCNA equivalent or work experience for it. Who should attend? ECMS1 is recommended for Meraki operators interested in introductory-level technical training or in preparing for the Cisco Meraki Solutions Specialist certification. As it is a technical course, individuals should be CCNA-certified or have an equivalent level of technical expertise. We do not recommend that those who have already attended CMNO attend this training, as the content is the same. This is mainly to ensure that participants know about networking, know what a switch is, and so on. I'd say, after attending CMNO, that participants who don't know basic networking, will not benefit from the CMNO course. That being said, CCNA is not a requirement. Only a recommendation. I attended the CMNO with a colleague of mine (Solutions Architect in datacenter), and he struggled a bit in navigating the dashboard, and typing things in correctly....

You will need to remove the APs from the network first, before you can unclaim the devices from your organization. Choose the network you wish to remove the APs from, and click Wireless -> Access Points, and find the AP you wish to remove. Select the AP checkbox from the list, and click on Edit -> "Remove from network..." Afterward, you can continue to unclaim the device from the dashboard. If you wish to move the AP to a different network, within the same Organization, choose "Move to another network.." rather than "Remove [..]". @adixxx wrote: Hi, I am planning to move one of my AP to another network but it won't let me. I followed the steps how to do it but I am having error and can't do anything from here. https://documentation.meraki.com/zGeneral_Administration/Inventory_and_Devices/Using_the_Organization_Inventory Navigate to the Organization > Inventory page. Check the box for the device(s) to unclaim. Click Unclaim. The device(s) will disappear from the list.

Recently, I had an installation at a Hotel which required a VLAN specifically for Television. They wanted an IP net, where 3rd octet referred to floor, and 4th octet referred to room number. That ended up being a /21 network. Albeit, with only about 150 hosts.

If you have another network, you can check the delay No. I could not see the log entry at 13:30, untill 13:54. The entry at 14:00, did not appear until at 14:07. Another thing I'm curioust about is that I have difficulty in believing that I'm getting the same two "Source IP and/or VLAN mismatch" events every 30 minutes, precisely on the second, for the last month.

rhbirkelund · ‎Mar 20 2019

I checked in on the Event log at 14:06 and nothing. Shortly thereafter;

rhbirkelund · ‎Mar 20 2019

Is there a 20 minute delay in event logs? At 13:54, the log entry at 13:30 appeared. Even after refresh, as well as clicking Network Wide -> Event log, several times in between.

I've heard that creating vlans (broadcast domains) too big will result in traffic drowning in broadcasts due to things as ARP and such. But nothing citing when domains are too big. Whether stated by law or rule of thumb. Dave, suppose you could bring any insight into this? Or anyone else, for that matter?

How is Client IP Assignment configured for the SSIDs under Wireless -> Access Control?

rhbirkelund · ‎Mar 15 2019

I might just be me, who is unable to google it. But when will the Meraki Documentation be updated with the new MX Beta feature on NAT Exceptions?
