I am not able to get all the MIB data using OpManager, but am able to access them though other NMS.
The specific problem is:
I am not able to access MIB table data of most tables. Only get works. Get Next does not go to the next parameter. Some of the parameters are marked "blue" and these are accessible through Get.
Please refer the attached file for more details. Parameters marked with "red circle" are accessible though other NMS. Tables with such parameters are not accessible.
