You can configure a managed appliance that uses single-port communication to use the Central Management System appliance for DTI services, but to fail over to the HTTP proxy server if the Central Management System appliance becomes unavailable. This is the default behavior when an HTTP proxy server is configured and enabled on the appliance.
Go to CLI configuration mode:
hostname > enable hostname # configure terminal
Configure and enable the proxy server as described in Configuring HTTP proxy server settings using the CLI
Verify that the Central Management System appliance controls the active settings for the DTI services, that the HTTP proxy server is enabled, and that HTTP proxy settings are disabled for DTI services:
hostname (config) # show fenet dti configuration brief
Save your changes:
hostname (config) # write memory
Example
The following example configures minimal settings for an HTTP proxy server and then enables it. It then shows that the Central Management System appliance currently controls the active settings for DTI services, that the proxy server is configured and enabled on the appliance, and that proxy settings are currently disabled for DTI services.
If the Central Management System appliance becomes unavailable, the values in the ACTIVE SETTINGS section change to DTI, and the values in the ACTIVE SETTINGS FOR HTTP PROXY section change to yes.
