We are implementing dot1x authentication with Cisco ISE and MS120, MR33 and MR46. Every thing works fine but we can't implement Fail Open.
Our goal is that when Meraki switch or AP lose connection with Cisco ISE, like Cisco classic switches, use Fail Open function and permit all clients to the internal vlan (don't authenticate and permit every client) until the connection with ISE comes back again.
Now, when the switch or AP can't reach the ISE If I have a guest vlan configured, they redirect the users to the guest vlan. But if I don't configure the guest vlan, they don't authenticate new users and block the access to the network.
Unfortunately I can't find any information about this in Meraki documentation. Is Fail Open function available in Meraki?
Thank you in advance.
