Hi Folks,
I am using 'snmptrap -Ci ' to send snmpv3 informs . Noticed scenario on
one device where snmptrap command stuck and gdb shows that flow stuck
in snmp_synch_response_cb() . File snmp_client.c, flag state->waiting set
to 1.
Kindly guide .
According to my knowledge, snmpinform will timeout after given period.
Here timeout is 2 seconds and retry 2.
