After all the switches are boot up after the power failure in the server. I notice that my stack switches some of the member switch got this alert message indicate DNS is misconfigure. Solution i force reboot the switch having this issues by unplug the power cable and plug back. After the switch is being force reboot, the issues does not happen anymore. Does any one know the root cause of this?

i already open a case already, meraki side say firewall issues, my firewall side said is your meraki lacp got issues. Cause the same thing happen to my load balance when we power of the switch, will cause my load balance side both link to down for couple sec. once the both link is down, my load balance will failed over. first things why when we power off the switch both link will down? we suspect on the meraki switch side.there is some limitation at the LACP side

Hi all, We have 2 x MS225-24 running in stack mode with latest stable version 10.45. A Cisco Firepower 2130 with a port-channel running LACP against the Meraki stack, 1 link per stack member. When powering off one of the stack members, it also affect the other switch, bringing the whole port-channel down. Once the port channel is down, the whole network will be down. Have you faced any similar issues? We do not face any issues on MS425-16 stack. for this test, the design was as follows: laptop running ping to gateway and internet -----> MS425-16 stack -----> Cisco Firepower working in Active/Spare mode ------> MS225-24 Stack -----> Load balance -----> Internet. Firewall 1 port 13 to MS225-24 Switch 1 Port 27 Firewall 1 port 14 to MS225-24 Switch 2 Port 27 Firewall 2 port 13 to MS225-24 Switch 1 Port 28 Firewall 2 port 14 to MS225-24 Switch 2 Port 28 Firewall configuration Firewall 1 port 13 and 14 is port channel. Firewall 2 port 13 and 14 is port channel MS225-24 configuration MS225-24 Switch 1 Port 27 & MS225-24 Switch 2 Port 27 (Aggregated) MS225-24 Switch 1 Port 28 & MS225-24 Switch 2 Port 28 (Aggregated) We try remove the link from one of the MS225-24 Switch 1 Port 27 and Port 28, the port channel never go down.
