Hello, today i noticed something regarding the stacking cables (MA-CBL-40G). For a while we had issues creating stacks... the stacking ports would not come up in 9 out of 10 tries/reboots. Finally, i think i found the cause: This must be due to some old stacking cables our customer had. I have cables, which are labeled with "MA-CBL-40G-50CM 600-22120" - these are the ones, which do not work most times in our MS410-16 switches. And i have cables, which are labeled with "MA-CBL-40G-50CM 600-22120-A" - these cables work just fine with the MS410-16. I was just wondering if there are really two different revisions of the cables... i've never read anything about this so far. Can someone confirm this? Or had similar issues with stacking? Best regads Tobi

We ordered the WW model and also dashboard tells me it's a MX67C-WW. However, it really looks like this is something, which can only be resolved by meraki support. i was just curious if somebody else experienced any issues with the integrated cellular too.

yes, there are models, which are working and some are not. We already cross-swapped the SIM cards, but that's not helping. So i tend to say there are some MXs, which have an issue with the cellular connections... Yes, they did have an active WAN port. lateste stable and beta firmware was tested. same result.

hi guys, we're currently have issues with some MX67C devices and the integrated cellular. I insert the SIM card (no PIN required), power up the MX, enable the integrated cellular, but nothing is happening. We already did a lot of tests... like using different SIM cards, configuring the APN, and others... but for now it looks like that it is related to the devices itself. This is the output of the "Uplink" tab: I can't see anything in the eventlog either. Did someone experience similar issues with the integrated cellular modems of the MXs so far? Thanks Best regards Tobi

Thanks for your answers. i think we'll stick to limit the communication at least to the described UDP port ranges. The problem with the manual port forwarding is that i can only configure 1 public IP... If we have a outage of the primary ISP in the data center then VPN wil not form over the backup ISP, right? Thanks

Hi, I currently have a deployment with about 40 sites connecting to a data center via internet and MPLS. Our data center MX is behind a Sophos UTM in one armed concentrator mode. On the Sophos UTM i created all the firewall rules for the ports, which the MX in dashboard under help -> firewall info is suggesting, but it seems that auto-vpn in automatic mode is not working properly. I can also see in the logs of the UTM that the MX is trying to communicate over a lot of UDP highports - i guess this is related to the "automatic mode". However, I'm not a big fan of those "any-any" firewall rules, so i am wondering if there is a recommendation for what ports are needed to be open from the MX to the internet and what ports may be needed to be forwarded from the internet to the MX appliance. i couldn't find any clear statement in the documentation on that. Thank you. Best regards Tobi

I can tell that we have a notebook, which wasn't connected to the network for the last 6 weeks at least and it still shows a public IPv6 address. We also checked with wireshark for any DHCPv6 traffic, but no router does assign addresses (as expected now).

Hi, i'm seeing public IPv6 addresses for some clients in my network, but if i run a "ipconfig -all" on that client, the IP address is not assigned to the client. So i'm wondering, how long does the dashboard store IP address information for clients? There might be some time in the past where clients could have gotten a public IPv6 address from our router, but that was almost half a year ago... Even if i click "forget client" only the traffic statistics are cleared... the public IPv6 address is still shown in dashboard. Thanks Best regards Tobi
