JUDGMENT OP1 TN received SNMPv2C response from NUT responding to SNMPv2C Get scalar object request correctly. Received packet with 1. SNMP version = 1, Community=same as NUT's SNMPv2C community PDU type = A2 2. Request-id is the same as the request id in the previously received SNMPv2C GetRequest. 3. Error-status must be equal to zero and error-index must be equal zero. 4. Value field is the system descriptor in system group of NUT with correct syntax type and value within the defined range field.

I am not sure I understand the report correctly. In the TEST PROCEDURE chapter, there is a simple call-flow, where NUT (i.e. RHEL 5.3/snmpd) sends trap to the test suite running somewhere. So far so good. But just one line below the description says "1. TN sends SNMPv2C Get scalar object to NUT by issuing SNMPv2C Get ...". This PDU is not in the call flow. And why it should be sent???? IMHO the description does not fit to the call flow above. From the test output I guess that the test suite does not send any packet and it just waits for (any?) incoming trap. I miss some indication what stimulates snmpd to send a trap - trap is notification, that 'something' happened. And the 'something' should be explicitly configured in snmpd.conf, together with trap target. E.g. if you add 'trap2sink udp6:[::1]:162 public' to your snmpd.conf, snmpd will send all traps as SNMPv2 traps to [::1]:162. You can configure various events, which shall be reported by traps, e.g. you can send a trap when amount of free disk space becomes lower than 100MB. See man snmpd.conf, section "DisMan Event MIB". By default, snmpd sends SNMPv2-MIB::coldStart trap on startup, maybe it's enough for your tests. All you need to do is to set it's destination using trapsink, trap2sink or trapsess statement in snmpd.conf (depending if you want SNMPv1,v2 or v3 trap) - see appropriate man page.
guys, is here any progress on this test case? Did you manage to get a trap out of snmpd? Do you need any assistance?
yes.the test suite did not send any packet and just waits for incoming trap. I add trap2sink udp6:[::1]:162 public to snmpd.conf, and run snmptrap -v 2c -c public udp6:[::1]:162 "" SNMPv2-MIB::coldStart but the case still failed.
