I'm just getting started with snmp. I've got the Microchip code in my
application and can do snmpwalk to see everything.

So, I modified snmp.mib so say:

 **************************************************************************=
**
 *    MIB-2 SYSTEM MIB
 **************************************************************************=
**
 $DeclareVar(SYS_NAME, ASCII_STRING, SINGLE, READONLY, 43.6.1.2.1.1.5)
 //$StaticVar(SYS_NAME, Microchip)
 $DynamicVar(SYS_NAME, 0)




I then ran

 mib2bib -I=3D..\ /q /b=3D..\WebPages\ snmp.mib



to create
Output BIB File: ProjectDirectory\WebPages\snmp.bib
Output Inc File: ProjectDirecotry\mib.h

I then ran the MPFS Generator to put snmp.bib in the file system.

I modified CustomSnmpApp.c to add this :

 BOOL SNMPGetVar(SNMP_ID var, SNMP_INDEX index, BYTE* ref, SNMP_VAL* val)
 {
     BYTE myRef;
      DWORD_VAL dwvHigh, dwvLow;
     DWORD dw;
     DWORD dw10msTicks;

     myRef =3D *ref;

     switch(var){
    ...
     case SYS_NAME:
       val->byte=3DModelString[myRef++];   // send next byte of string
       if(ModelString[myRef]=3D=3D0) myRef=3DSNMP_END_OF_VAR; // end of str=
ing,
mark it
       *ref=3DmyRef;
       return TRUE;
       break;





When I run snmpwalk, I get this:

 snmpwalk -v 1 -c public 192.168.1.159 .iso

 SNMPv2-MIB::sysObjectID.0 =3D OID: SNMPv2-SMI::enterprises.17095

 SNMPv2-SMI::enterprises.17095.3.4.0 =3D INTEGER: 0
 End of MIB




sysName picked up sysLocation instead of sending ModelString. When I set a
breakpoint after case SYS_NAME:, it never gets hit.

So... clearly I'm doing something wrong! Can anyone tell what it is based
on the description I've given?

THANKS!
