AP Connection Loss to Cisco Meraki Cloud

Connectivity loss can occur for several reasons: your WAN connection goes down, a Meraki data center experiences an outage, or there is an Internet routing issue between your site and Meraki.  This article describes the behavior of your wireless network under this "connectivity loss" state.

The Meraki Cloud is an out of band architecture, meaning that no client data flows through the Cloud.  The system is also designed to handle connectivity failures gracefully.

In general, wireless clients will continue to be able to use the WLAN during a connectivity loss.  Clients will continue to be able to access local LAN resources (e.g., printers and file shares) and, if an internet connection is available, the Internet as well.

When your network is in the "connectivity loss" state, you  will notice the following changes:

  • Network configuration changes will not take effect
  • Usage statistics will become out of date
  • Channel spreading and other optimizations will not run
  • The Rogue AP list will not update
  • If you are using Meraki-hosted RADIUS for authentication and Controller Disconnection Behavior is set to "Retricted", new clients will not be able to authenticate.  By default, all new clients are denied.  You can also select for all new clients to be allowed (Open).  Clients who have already authenticated continue to function normally.
  • Newly associated clients will not see Meraki-hosted splash pages.  Clients will be given access without seeing the splash page. (depends on settings on Configure -> Access Control -> Controller Disconnection Behavior)
  • If you have Meraki Billing enabled, new clients will not be able to purchase network access.

These services will automatically resume functioning once connectivity between the wireless network and the Meraki network is restored.

If a Meraki data center experiences an outage, your network will automatically fail over to another Meraki data center. During the fail-over time your network will experience connectivity loss as described above.

Assuming you have setup email alerts, you will receive an email when a Meraki node loses connectivity to the Cloud, allowing you to take corrective action if necessary.
