This boolean field controls whether this log export policy authenticates to the remote export server using passwordless SSH, key-based, authentication instead of a password. An admin enables this to avoid storing a plaintext password in the policy configuration, relying instead on pre-shared SSH keys for the log export. For example, an admin who has already set up SSH key trust between the fabric interconnect and the remote server enables PasswordlessSsh on this log export policy so exports no longer depend on the Pwd field at all.
