The QStar SNMP supports SNMP protocol version 2c.

2 Since the QStar SNMP supports SNMP protocol version 2c, so for all command line utilities you should specify option -v 2c. Install and configure Windows SNMP service Windows Feature SNMP Service should be installed. Microsoft how to instructions are available at the URL : Check this in Administrative Tools -> Server Manager -> Features: Please configure Windows SNMP service in Administrative Tools -> Configuration -> Services:

3 The properties tab Security contains list of communities and list of permitted hosts: Communities are like passwords to access the SNMP with specified rights (READ ONLY or READ-WRITE). If you do not see the tab Security, please reboot the computer and return to service properties. The properties tab Traps contains list of external hosts that will receive SNMP traps:

4 If you do not see the tab Traps, please reboot the computer and return to service properties. Alternatively, the Windows command evntcmd can be used to configure trap destinations. For that create file with Trap destination (for example trap.txt). The content of the file trap.txt shall contain line like: #pragma ADD_TRAP_DEST public Then execute command: evntcmd trap.txt For more information please refer to this site: Install QStar ASM SNMP (Windows) QStar SNMP agent should be selected during QStar ASM installation (QStar_6.0.*.exe):

5 QStar ASM SNMP testing Test SNMP functions in ireasoning MIB Browser ireasoning MIB Browser Free Personal Edition can be downloaded as setup.exe (Windows) file from this URL: Installation is very simple. Start graphic browser by executing bin\browser.bat or for Windows setup.exe Connect to SNMP service on node Nadine :

6 Load QStar asm.mib : The asm.bin file is located in C:\QStar\snmp directory. File->Load MIBs. Expand the MIB tree, find QStar ASM nodes:

7 Test SNMP GET (and Get Next) command: Scalar values can be retrieved by double clicking their names in MIB tree, or one by one by pressing Go button in top right windows corner (when Get Next is selected):

8 SNMP tables cat be opened as follows:

9 Test SNMP SET command (mount and unmount QStar ASM Integral Volume set): Place cursor into column status of the row udf_sv, press the button SNMP SET:

10 Type the value (mount point) U:, press Ok: The volume udf_sv is now mounted as U:

11 Do SNMP SET with empty value to unmount: Test SNMP TRAP processing Enable SNMP traps in QStar:

12 Open trap receiver in ireasoning window: Simulate a trap (from inside of QStar), using the set of commands in the batch C:\QStar60\bin\do_trap.bat : These CLI commands cause trap to be sent because UDF set is mounted with clean cache and media is exported. The dir U: command caused to read directory from media which is not in the library. That generates error message (and SNMP trap).

13 vlcmd.exe umountiv udf_sv 2> nul vlcmd.exe mountiv -n udf_sv U: echo. vlcmd.exe export jb_sdisk 10 start cmd /C dir U: vlcmd.exe import -S+ jb_sdisk 10 vlcmd.exe umountiv udf_sv We got the trap: Easier way to simulate the trap is to invoke the command: qscmd qslog -ee -p VL -m "Test Message" Test SNMP functions using remote Linux commands Described on example of usage from the Ubuntu machine SUSAN. Please make sure that following packages are installed (apt-get install): snmpd, libsnmp15, snmp, libsnmp-base.

14 Please make sure that the file SNMPv2-SMI is presented in /usr/share/mibs/netsnmp/ (can be downloaded here Please make sure that the file QSTAR-ASM-MIB is presented in /usr/share/mibs/netsnmp/ (can be copied from cvs60\snmp\lib\asm.mib) Test environment Assume that is IP address of Windows machine NADINE (please make sure that Windows SNMP, QStar Server and QStar SNMP Agent are configured and running there).

15 Test SNMP TRAP Please run : /usr/sbin/snmptrapd -f -Le --disableauthorization Please make sure that on Windows machine in SNMP service settings, Trap page, IP address of Ubuntu machine ( ) is specified in Trap destinations list. Please on Windows the batch C:\QStar60\bin\do_trap.bat that raises the trap condition. In couple of seconds you should see following trap text in Linux snmptrapd output: :06: (via UDP: [ ]:52537->[ ]) TRAP, SNMP v1, community public QSTAR-ASM-MIB::qNotif Enterprise Specific Trap (1) Uptime: 1:34:22.65 QSTAR-ASM-MIB::qNotif = STRING: "INFO VL-UDF: set udf_sv, single volume, offline udf_sv_0_1:under the table: Please vlimport medium." Disable QStar SNMP (Windows) To disable QStar SNMP Agent, please remove in Windows registry a reference to qstarsnmpagent from the list of Extension Agents: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SNMP\Parameters\ExtensionAgents] remove a string value "qstarsnmpagent". After that Windows SNMP service should be restarted (stopped and then started). Configure Net-SNMP Configure snmpd for execution on Ubuntu Please make sure that following packages are installed (apt-get install): snmpd, libsnmp15, libsnmp-base. Please make sure that the file SNMPv2-SMI is present in /usr/share/mibs/netsnmp/ (can be downloaded here Please make sure that the file QSTAR-ASM-MIB is present in /usr/share/mibs/netsnmp/ (can be copied from cvs60\snmp\lib\asm.mib) Configuration file /etc/snmp/snmp.conf should contain the line mibs QSTAR-ASM-MIB Changes in configuration file /etc/snmp/snmpd.conf : # AGENT BEHAVIOUR # Listen for connections from the local system only #agentaddress udp: :161 # Listen for connections on all interfaces (both IPv4 *and* IPv6)

Please specify in Windows registry a reference to qstarsnmpagent in the list of Extension Agents:

18 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SNMP\Parameters\ExtensionAgents] "qstarsnmpagent"="software\\qstar Technologies, Inc.\\qstarSNMPAgent\\CurrentVersion" Please specify in Windows registry path to QStar SNMP Agent DLL: [HKEY_LOCAL_MACHINE\SOFTWARE\QStar Technologies, Inc.\qstarSNMPAgent\CurrentVersion] "Pathname"="C:\\QStar\\bin\\qstarSNMPAgent.dll" After agent installation Windows SNMP service should be restarted (stopped and then started): Starting and Stopping SNMP support processes on Linux SNMP management is a system wide operation and QStar QSM provides only SNMP subagent which can t operate by itself. The system administrator is responsible for starting and restarting SNMPD daemon using his own judgment and system requirements. QStar ASM start scripts will not stop or start QStar ASM SNMP subagent because SNMP services work independently of QStar and provide possibility to check QStar ASM status independently. The QStar SNMP subagent can be started manually using script in install directory. The script qsnmp_rc allows to start, stop and restart QStar ASM SNMP subagent. If needed that script may be added to the other scripts as scripts. qstarsnmpsubagent run options

19 Normally qstarsnmpsubagent should be executed without any options. It is running as daemon. For debugging purposes it can be started as./qstarsnmpsubagent -D qstar_handler -f -Lo -x tcp:localhost:705 For specific debug of trap handling it can be started as./qstarsnmpsubagent -D qstarsnmpsubagent -f -Lo -x tcp:localhost:705 Detailed instruction on all options can be obtained by./qstarsnmpsubagent h
