As part of the Cisco Meraki cloud management platform, statistics, configuration, and other information for devices can be found in Dashboard. To maintain this information and monitor device reachability, each device uses about 1 Kbps (or less) to securely communicate with Dashboard. Thus even a network with 100 Cisco Meraki devices would only generated about 100 Kbps of management traffic under normal conditions.
If a configuration change, firmware update, or polling of live information needs to occur, additional management traffic will be generated as a result.
For more information on the Cloud Management platform, please read the Cloud Management whitepaper.
If any Cisco Meraki devices are having trouble reaching Dashboard, please make sure the necessary rules have been added to any upstream firewalls. Information about what ports and IP addresses are used for management traffic can be found under Help > Firewall info in Dashboard.
