Subject: alarm table implementation 

 

Hi,

 

   Iam using latest Net-SNMP latest version for SNMP agent and
subagents. Need to provide support for alarmTable for all the 

   notifications SNMP agent sends on behalf of our subagents to trap
destinations. For this I have modified the routine "send_v2trap

   routine in agent/agent_trap.c file.  Included alarmtable structure in
agent_trap.h file.

 

   Using mib2c -c mib2c.iterate.conf file I have generated alarmTable.h
and alarmTable.c. These files I have copied in mibgroup/alarmTable

   directory and registered the mib.

 

    So when a new alarm comes it writes to the alarm table structure and
updates the pointer. Till this it is fine. Now my problem is

    that when Iam doing SNMP get on the table it uses the structure
variable declared in agent_trap.c, but I don't get the variable 

    address pointer, it is always having NULL value. 

 

    Has anyone faced this kind of problem? How can I get the address
retrieved in another file?

 

   1)  agent_trap.c

          Struct alarmTable_entry *alarmTable_head;

 

  Send_v2trap()

     << updating the alarmTable_head pointer

 

  2)    Mibgroup/alarmTable/alarmTable.c

           Extern struct alarmTable_entry *alarmTable_head;

 

          If (alarmTable_head)   << This is always having NULL value.

                << SNMP get to retrieve values

   

   

   Thanks for the help in advance.

 

 Thanks & Regards,

  Raj.
