[ปลาวาฬทราย RMUTT CPE IX]

Hello,

I used OID: 1.3.6.1.4.1.9.5.1.2.16. Some IOS can't not get the data such as:

• c2950-i6q4l2-mz.121-9.EA1.bin is blank.
  
• c3550-i9q3l2-mz.121-13.EA1a.bin is J0.
  
• cat4500e-ipbasek9-mz.122-53.SG1.bin is blank.
  
• ...
  

Have the other OID for these IOS

Thank you very much.
