When you query the ifOperStatus object identifier (also known as OID) on a Windows Vista-based computer, you experience the following problems:

• If the interface state is “up,” the query returns 5 for the value of the ifOperStatus object identifier.
• If the interface state is “down,” the query returns 0 for the value of the ifOperStatus object identifier.

For example, you receive the following query result:

Variable = interfaces.ifTable.ifEntry.ifOperStatus.1
Value    = Integer32 5

Variable = interfaces.ifTable.ifEntry.ifOperStatus.2
Value    = Integer32 5

Variable = interfaces.ifTable.ifEntry.ifOperStatus.3
Value    = Integer32 5
