I have a setup of Cat 9k Meraki all having this UDLD issue on copper ports, all connecting to C9300-48UXM and C9300-48UXM uplink to MX. 1 C9300-48UXM 2 C9300-48U 2 C9300-48P   4 of the setup are now running CS 16.9 and seems stable for the past week after i did the firmware upgrade but one unit of C9300-48P is still refusing to function properly, may need to directly link it to the MX to allow proper upgrade of the firmware. ...

As stated by @RaphaelL L3 rules based on FQDN will break as they rely on snooping client DNS traffic. https://documentation.meraki.com/MX/Firewall_and_Traffic_Shaping/MX_Firewall_Settings#FQDN_Support   L7 firewall rules and content filtering will work based on the destination IP of the client's traffic.l However you will lose L7 firewall rule enforcement based on client DNS lookup (where the MX blocks the actual DNS request due to an L7 firewall rule match) ...

Very interesting... We also have a similar issue. We are adding an MX 67 on our spokes that goes over AutoVPN to our DC and it only happened a few times in the beginning, but now with every migration of adding an MX 67 to a spoke for SD-WAN, we need to reboot our MX.  We are also connecting to a Fritzbox and most of the time it is the 7590. We just passed the 100 mark for migrations, but our issue is with the CAP WAP traffic of Cisco AP's that do not want to show up on WLC (Flex Connect) and the only option at the moment to fix this is to reboot MX then it is fixed.  We do have an open case with Meraki and they have no clue why it is, but we can see that the UDP port is changed when it comes back to the spoke. I am going to check the firmware of the Fritzbox and see if this is related.  ... View more

Unless you are actively blocking those currently, which sounds unlikely baed on your question then you should not have to do anything except ensure anything upstream from your network is not blocking.   Short answer: no need to do anything in most cases.  Those who need to make changes would know how and where.   ...

If you look at the client page and add the port column, you will see for many MXs that the port shown is indeed N+1.  Therefore port 2 is the labelled port 3 as @alemabrahao stated.  Try on your network and this will confirm it for you, but it is definitely the case for an MX75. ... View more

Is there a web site available where i can input the serial no. of the MS120-8LP and see if my power supply is affected?  Appearently this is possible for Meraki engineers if i read this article, but we have approx 3000 of these in the field.   https://documentation.meraki.com/General_Administration/Support/MS120-8LP-HW_Power_Supply_Proactive_Replacement_Overview_and_FAQ   I also would like to know if there is any risk on: - firehazard - safety of users  - safety of connected equipment on the switchports - is there any risc of the MS120-8LP switch being damaged?   ...

Opened a case. The response i got back from Meraki is that:  - there is no switch ASIC in these MX68 / MX65 devices, and therefore these options are not available - this is also not possible using API   Best i could do was to submit a feature request..Did that.   ... View more

The last part of the doc is actually incorrect. You don't need to unbind anything to add a MG into a bound network. Steps to get it done are this. I also created a video walking through it.   1. Ensure your template supports the MG device type which is outlined in this section of the doc. More recently created combined templates should already have MG, MV, MT device groups in them. 2. Create new MG network 3. Bind that MG network to your template (requires step 1 to be completed) 4. Optional, combine the previous MX, MS, MR network with the new MG network into one bound combined network ... View more

I would ask your Cisco reseller for a free trial to be sent to one of the sites.  If it works you can just pay for it and keep it.  It seems very unlikely for an ISP to be blocking Meraki.     ... View more
