I downloaded RFC1155-SMI and tried to load it with the SmiManager for SNMP4J-SMI-PRO 1.8.0. It failed with: Syntax error: Encountered "EXPORTS internet" at line 3. The reason why I am loading this is because RFC1155-SMI is an import for powernet412.mib which I am having difficulty compiling due to Integer32 and Unsigned32 not being defined. Ron
