NMS SNMP MIBs are compiled using the following text files, located in \nms\ctaccess\doc (/opt/nms/ctaccess/doc under UNIX):

MIB | File
Chassis | chassis-mib.txt
Trunk | trunk-mib.txt
Software Revision | softrev-mib.txt
OAM Database | oamdatabase-mib.txt

To display the SNMP information for the proprietary agent, read the appropriate file using the Windows Console Management function.
