Appendix A.4. 

Controlling how a MIB file reports traps 

The connection parameter ‘Do_not_MIB_this_Node’ controls whether a Node’s traps contribute to the 
MIB file.  This parameter is useful where duplicate traps are being sent to more than one destination. 
  
Some  aspects  of  how  traps  are  reported  in  the  MIB  file  may  be  controlled  with  a  Node  parameter 
called ‘MIB_Style_for_Traps’ 

 

Adapters 

 

 

 

Adapter,  

Protocol, 

Poll_Delay, 

MIB_Style_for_Traps 

N1,  

SNMP,  

0.1s,     

Style1 

 

Permitted Values for the parameter are: 
 
Style1 (Default) 
Style2 
Style3 
 
Style2 and 3 add information to the trap description on the trap origin. 
Style3  defines  the  parameters  contained  in  each  trap  and  assigns  these  parameters  hard  coded 
OID’s which are fixed for all traps.  In Style 1 and 2, the parameters are not reported in the MIB file 
and the parameter OID’s are based on the trap OID.  Thus style 3 changes the structure and data of 
the MIB from Style1&2.
