This read-create SnmpAdminString (1-64 characters) is a write-only-in-effect trigger: setting it to a name clones the current zone under that new name, while reading it always returns the zero-length string. Admins use it to quickly duplicate an existing zone's membership as a template for a new one. For example, an admin setting up a near-duplicate zone for a redundant storage path would set this object to the new zone's name to clone the existing configuration.
