This Cisco APIC-EM release supports the new Remote Troubleshooter application. This application uses the Cisco IronPort infrastructure to create a tunnel that enables a support engineer to connect to an APIC-EM cluster and troubleshoot issues with your system. The app uses outbound SSH to create a secure connection to the cluster through this tunnel.
Before you use the Remote Troubleshooter application, ensure that you have internet connectivity, with at least one of the following ports enabled for outgoing SSH connections: 22, 25, 53, 80, 443, and 4766.
Enabling the Remote Troubleshooter
From the global toolbar, open the Administrative Functions menu and then select APIC-EM > App Management.
The Controller Management page opens with the Applications tab selected by default.
In the Installed Applications table, locate the TechnicalSupportTunnel entry and then click Enabled from the Status column.
The Remote Troubleshooter app icon is now displayed in the navigation pane.
