This chooses whether this node generates standard RFC-defined generic traps or the corresponding enterprise-specific traps instead, for situations where both exist for the same event. An admin managing a mixed-vendor NMS that only understands generic SNMP trap types, such as linkDown or coldStart, would set this to rfc, while one using vendor-aware management software that can decode Codex-specific trap varbinds would set enterpriseSpecific to get richer detail. For example, setting this to enterpriseSpecific might turn a generic linkDown trap into a Codex-specific trap carrying additional detail like which board and port failed.
