Hi Community, I have a setup where the Meraki MX is handling: Inter-VLAN routing, DHCP services, Firewall rules for VLAN-to-VLAN traffic Meraki switches and APs are also part of the same network, and the clients are connected via these switches. Now, I want to monitor or troubleshoot real-time communication between a Source & Destination at the same site — for example: Source: VLAN 10 (IP: 192.168.10.5) Example - OT Endpoint Destination: VLAN 20 (IP: 192.168.20.5) Example - Printer The MX is routing between them, and firewall rules are allowing the traffic. What I want to know: 1. How can I confirm in real time that packets are flowing between these two devices? 2. Is there a way to see active sessions or flow logs on the MX dashboard? 3. Can I view this in event logs or only via packet capture? 4. What’s the best practice for troubleshooting such inter-VLAN communication or any inbound or outbound communication through MX? I’m not using a syslog server. Appreciate any guidance or tips — especially for tools built into the Meraki dashboard. ... View more

Hi,  I am planning to replace MV32 that went faulty due to weather conditions with a new model. Since I'm new to this product, I would appreciate any guidance you could offer on the best practices for replacing the MV.  I was considering connecting the new unit to the same switch port. Additionally, is there any cloning or configuration required for the new device, similar to what we do for other equipment?  Thanks ... View more

Hi,    We have the below switches in the topology. The access switches connect to the Core switch using Agg ports. Core Switch (Stack of 4)  3 - MS225-48 & 1- MS225-48FP 3 access switches - MS125-48FP & MS120-8 All switches are running on firmware 15.22  Core switch STP bridge priority is set at 8192 & other access switches are on default value 32768. Recently, there was a power outage at site & 3 access switches were on raw power. The switches went down & came back up but they started behaving weird with DNS errors, unable to fetch configuration, devices showing Red on Dashboard etc. In the event logs there were just MAC address flapping logs so we thought the there is a loop causing the network to fluctuate. Case raised with TAC & they initially suspected loop but later requested to power off/on the switches & reset one of the switches. Once we did that one switch started functioning properly. But other switches were still in the same state & hence TAC raised RMA. Now, the strange part - The 2 switches that weren't coming UP (Now RMA'd) suddenly turned green after almost 5-6 hours & are performing well. We will replace those switches anyway. My understanding is the power issue caused a communication issue between switches and Core stack or may be there was a glitch that got cleared but i am unable to understand why the switches came UP after 5-6 hours.   Has anyone faced this issue & can help me understand this problem. Do i need to validate a few settings ?     Thanks! ... View more

Hi Community,    Recently high bandwidth consumption on WAN was reported & i was provided a list of DCs & AP (MRs) that were seen downloading & uploading data. This was captured on the gateway (L3/FW) which is managed by a different vendor. I'd like to know is there a way at the AP level where i could find the destination traffic & what is consuming so much bandwidth. Any suggestions where i can start or anyone has tshoot this, any services running that could utilize BW?   Thanks! ... View more
