Each Cisco Meraki product has a minimum firmware version that it can run which may not always match up with what the dashboard network is configured for. Therefore the node will run the minimum firmware it is capable of running, which may be higher than the network configured firmware. This article will list each currently supported MR, MS, and MX product and the minimum firmware they can run.
Additionally, some devices which have reached end-of-sale may have maximum support firmware versions. The node will not be able to run firmware versions newer or higher than the indicated maximum version.
This article will not include the MV products because they do not have a minimum product firmware version more recent than what is available in dashboard, so it is not susceptible to same same conditions yet.
Note: Meraki recommends checking the Organization > Firmware Upgrades page to verify which firmware version your network is running, rather than referring to the available firmware messages that may be presented for each individual device. The Firmware Upgrades page is the best method to ensure you have the most recent build.
As of 2020, there is a separate minimum firmware version that is needed to be able to connect to the Meraki dashboard. To see these firmware requirements, please see the Security Expiration 2020 FAQ.
