Technical Tip: Ruckus Wireless LAN Controller (Zone Director) CLI communication failure

This issue might be due to Banner enabled on Ruckus WLC which requires user to select 'Enter' after successfully authenticating to the controller.

When FortiNAC CLI tries to SSH the Ruckus controller:

> ssh <userid>@<device IP address>

If SSH was successful  the following message should appear:

Please login: admin

Password:

[Quit:input 'q', Continue:press 'Enter']:

If the credentials are tested for the Credentials tab while TelnetServer and Ruckus debug are enabled, the following logs will be visible in output.master.
