Authentication

IP Fabric interacts with the network infrastructure devices by running show commands through CLI using SSH or Telnet. Credentials added in the Authentication section will be used by IP Fabric to access the CLI of the network devices.

Credential Selection Logic

If more credentials are specified, a top-down algorithm is used when trying to login to a network device or the credentials priority can be changed using drag and drop.

Configure Network Infrastructure Access

Read-only (Privilege 1) credentials are sufficient for basic functionality. Security sensitive operations and advanced functionality might require higher privilege. See the full list of used command in the documentation.

When adding new credentials, you can limit the validity of the credentials just for a part of your network using Use in subnets and Don’t use in subnets fields.

Add new CLI credential

Provided credentials can be used for configuration change tracking and saved configuration consistency (i.e. they allow commands such as show run and show start).

To use this credentials for configuration change tracking, please check Use for configuration management box.

(Optional) Passwords for Enable Mode

Privileged credentials are generally only necessary for configuration management. However, some platforms require privileged credentials to access basic network state information, such as MST spanning-tree state or 802.1X session information.
