Issue/Introduction

• How to increase the limit for the varbinds?
• What is the default limit for the varbinds?
• Is it possible to increase the number of varbinds for the traps which are being processed by the trap adapter?
• some of the incoming traps contain up to 30 varbinds, but the trap_mgr_parse.asl script is hard coded to handle a max of 20 varbinds per trap.

 

Environment

SMARTS- 10.1.x

Resolution

• The trap_mgr_parse.asl ruleset file needs to be customized to handle the extra varbinds. 
  
  
   
• By default only 20 varbinds variables are available. However, below is how we can customize the trap_mgr_parse.asl to support 30 VARBINDS:
   

• persistentAdapter->setVariable("V20", "") ? IGNORE;
  
  
  
  
  Add similar statements upto V30 just below it.
   
  
  persistentAdapter->setVariable("V21", "") ? IGNORE;
  
  persistentAdapter->setVariable("V22", "") ? IGNORE;
  
  ....................................
  
  persistentAdapter->setVariable("V30", "") ? IGNORE;
  
  
  
  
  persistentAdapter->setVariable("OID20", "") ? IGNORE;
  
  Follow similar steps as mentioned for VARBIND for OID to add lines to support till OID30.
  
  persistentAdapter->setVariable("OID21", "") ? IGNORE;
  
  ....................................
  
  persistentAdapter->setVariable("OID30", "") ? IGNORE;
  
  
  
  
  
  
  
  if (defined(Varbinds[19])) {
  
  persistentAdapter->setVariable("V20", Varbinds[19]) ? IGNORE;
  
  persistentAdapter->setVariable("OID20", Oids[19]) ? IGNORE;
  
  }
  
  
  
  
  Add similar lines just below upto 30.
  
  
  
  
  if (defined(Varbinds[20])) {
  
  persistentAdapter->setVariable("V21", Varbinds[20]) ? IGNORE;
  
  persistentAdapter->setVariable("OID21", Oids[20]) ? IGNORE;
  
  }
  
  .....................................................
  
  if (defined(Varbinds[29])) {
  
  persistentAdapter->setVariable("V30", Varbinds[29]) ? IGNORE;
  
  persistentAdapter->setVariable("OID30", Oids[29]) ? IGNORE;
  
  }
