RADIUS authorization grants or denies access permissions for a 7705 SAR router. Permissions include the use of FTP, Telnet, SSH (SCP), SFTP, and console access. When granting Telnet, SSH (SCP), SFTP, and console access to the 7705 SAR router, authorization can be used to limit what CLI commands the user is allowed to issue and which file systems the user is allowed or denied access to.
