About the Web Interface
This section summarizes the Expressway web user interface, and the CLI and API.
System configuration is normally carried out through the web interface. To use the web interface:
-
Open a browser window and in the address bar type the IP address or the FQDN of the system.
-
Enter a valid administrator Username and Password and click Login (see the user accounts section for details on setting up administrator accounts). The Overview page is displayed.
If you receive a warning message regarding Expressway's security certificate, you can ignore this until you are ready to secure the system.
Field Markers
-
A red star indicates a mandatory field
-
An orange dagger † indicates a field that must be configured on each peer in the cluster

How to disable user access to the API
Administrators have API access by default. This can be disabled in two ways:
-
If the Expressway is running in advanced account security mode, then API access is automatically disabled for all users.
-
API access for individual administrators can be disabled through their user configuration options.
