Hi, I have good news! The issue has been resolved. When the problem reoccurred last Monday, I contacted Meraki TAC. After a thorough investigation, TAC discovered that a group policy was impacting CPU utilization. Specifically, we had configured a 10Mbps bandwidth limit and applied it to a particular client. Whenever traffic was high on that client, the group policy was actively limiting the bandwidth, which caused significant strain on CPU utilization and resulted in latency issues. After removing the group policy for that specific client, the issue has been resolved.

I don't have option of even replacing the device with edge router as we are completely dependent on auto VPN for our intranet connectivity and the impacted device is on a major site with around 1500 to 2000 users.

Just verified the graph. It was normal till Sept 14. We upgraded to MX 18.211.2 in month of July 2024. It was fine till Sept 14 2024. We have whitelisted around 20 rules in Intrusion detection and prevention as the trusted traffic in AUTO VPN was getting blocked. IDS Mode is Prevention and Ruleset is balanced.

This is the device Utilization from Sept 15. I had requested TAC for checking CPU Utilization and they confirmed there is spike in CPU Utilization but i didn't get any report. Average client count is under 1000 and some times it increases to 1890. The recommended client count for MX250 is 2000. When we were running in 18.107.10 the device was much stable. After the upgrade there is in increase in device utilization. I will check with tac if we can test by downgrading the MX to 18.107.10

Hi All, We are facing an unusual issue with our MX250. When business hours are about to start and the number of clients behind the MX250 increases, there is a sudden spike in device utilization, which leads to latency affecting all traffic passing through the MX. This latency impacts both WAN links and LAN-to-MX traffic. As a result, we also experience increased latency over Auto VPN traffic. Everything was functioning normally until mid-September. To stabilize device utilization, we rebooted the MX250, which temporarily resolved the issue for about three days. Initially, we were running MX 18.211.2, and TAC recommended upgrading to MX 18.211.3. The upgrade was stable for two days, but on the third day, latency increased again due to high device utilization. TAC then suggested upgrading to the MX 19.1.4 Beta version, but the issue persists. All necessary logs have been captured, but no solution has been found for this behavior. We are seeing traffic of only 100-150 Mbps when the issue occurs, and after a reboot, device utilization returns to normal. We’ve even swapped the primary MX250 with a spare unit, but the behavior remains unchanged. We tried disabling IPS/IDS, AMP and the behavior remains same. If anyone has encountered a similar issue with any of your MX devices, could you please share any fixes or suggestions?

Thanks Philip for the response. I'm trying to get a person who knows python. I suspect i'm missing some addons of the python as the same script is working in a different machine but not in new one. I had installed the latest version of python which is available from the web.

Hi Team, We are using meraki in our corp offices currently we don't have proxy setup. All the traffic is being filtered in the Meraki itself. We are planning to use Cloud Proxy setup through zScalar Site to Site Tunnel and the same has been tested. As per the document we have to use a script for performing a tag based failover of non-meraki s2svpn tunnel. The script sometimes break and we have relaunch it everytime it goes down. Do we have any updated script to test the failover scenario in non meraki s2svpn tunnels. As we are planning to have this setup from every network the script doesn't seems to be stable. Can i get some suggestion on this. Apart from this why doesn't Meraki support for having a Secondary Peer IP Address in Non Meraki s2s vpn tunnels. If such option was available then the running a script would not be required.
