RE: enum of syntax OCTET STRING in MIB design ...

Thu, 21 Sep 2006 01:32:31 -0700 

I validated my mib with the tool that you have specified I got the following error …
2329           SYNTAX              OCTET STRING {
   (1) syntax error, unexpected '{', expecting STATUS
                                                 None("NA"),


I will use any one of the option you have specified …



 



Thanks Dave

No - I'm pretty sure that this design is *not* valid.



Just because some random SNMP software doesn't complain - this doesn't



automatically mean that the MIB is valid.   Many software
packages



(including Net-SNMP) are relatively forgiving in their handling of MIB



parsing.



   If you want to check the validity of your MIB, you should
use one



of the dedicated MIB validation tools, such as "smilint" or
the Simple



Web validation page



(http://snmp.cs.utwente.nl/ietf/mibs/validate/)



 



I would be fairly surprised if these tools didn't complain about your



MIB design.



 



 



Two options spring to mind:



  a) either send the actual text you want to be displayed (i.e.



"United States"),
or



  b) use an enumerated integer instead:
