I have checked these configurable items but they did not help me.
SNMP agent is initialized using the following function calls
- init_agent() function where session is opened to the master agent.
Session attributes timeout and retries are set in
subagent_open_master_session() function
(agent/mibgroup/agentx/subagent.c)
(I have pasted the relevant lines of the function)
-----------------------------------------------------------------------------
sess.retries = SNMP_DEFAULT_RETRIES;
sess.timeout = SNMP_DEFAULT_TIMEOUT;
-------------------------------------------------------------------------------
These values are re-initialized in the function
_sess_copy() (snmplib/snmp_api.c)
(I have pasted the relevant lines of the function)
-----------------------------------------------------------------------------
if (session->retries == SNMP_DEFAULT_RETRIES)
session->retries = DEFAULT_RETRIES;
if (session->timeout == SNMP_DEFAULT_TIMEOUT)
session->timeout = DEFAULT_TIMEOUT;
-----------------------------------------------------------------------------
(Ctrl flow - snmp_open_ex -> snmp_sess_open -> _sess_open
-> snmp_sess_copy -> _sess_copy)
- init_snmp() function where snmp configuration files are
loaded and default_store is used to store the values loaded.
Looking into the code, it looks like the configuration files are
loaded after setting the session attributes. Please correct me if i am
wrong.
