Data ONTAP provides several methods that you can use to specify how a user account can access the storage system.
RSH is disabled by default.
Telnet is disabled by default.
Storage Virtual Machine (SVM) user accounts cannot use console, rsh, service-processor, or telnet as an access method.
If a firewall is enabled, the access method you use must also be added in the firewall policy to allow the access requests to go through the firewall. The system services firewall policy show command displays firewall policies.
