Many elements use string names as keys in model-driven interfaces instead of the numerical identifiers used in the classic CLI and SNMP.
Note: The string name can only be assigned or modified for these elements in releases before Release
15.1.R1. Elements without names are automatically assigned a name (the identifier
converted to a string) during an upgrade to Release 15.1.R1 or later, and cannot be
changed without manually deleting and recreating the element. It is recommended that the
following elements are assigned names before an upgrade to Release 15.1 or later.
