HI, "Standby status" items should be renamed to "standby state" to be consistent with the other naming of other items in the MIB module. (Items are "state" when value is an enumerated int, and "status" when the value is a bit string.) There is one important value missing from the enums for standby. It is the one that means that the service output is combined with other entities. This is commonly found with power supplies where the output is "summed". Section 2.2 is incorrect. It implies that by reading the value of entStandbyStatus for all entities, then entities can be classified as redundant (or protected). This is not true. Say that there are two entities that are identical and provide a "protected" service. At any time, only one is providing service, and the other is standing by protecting the other. A "protection switch" causes the roles to change (that is the one providing service will switch to standing by, and the one standing by will start to providing service). In general, this MIB module does not provide enough information to determine 1) which entities are protected, 2) the relationship between the entities that are protected and the entities providing protection.
