SNMP Prerequisites

New page

Starting in release 8.5.1, you can use Net-SNMP, instead of the Genesys SNMPA Master Agent component, to implement SNMP functionality. Net-SNMP supports everything that Genesys SNMPA Master Agent does, but uses any SNMP master agent, whether supplied by Genesys or by a third-party.

Net-SNMP and Genesys SNMP Master Agent can run in parallel on the same system. Solution Control Server and Local Control Agent support both implementations.

If you choose to use Net-SNMP in addition to, or instead of, Genesys SNMPA Master Agent, you must install Net-SNMP on each host that will be running SNMP master agents configured for use with Net-SNMP. Use the following instructions, according to the operating system running on the host.

To install and configure Net-SNMP on Windows 64-bit Platforms, use the following steps:

1. Download and run Net-SNMP as follows: [+] Show steps In a web browser, go to http://sourceforge.net/projects/net-snmp/files/net-snmp%20binaries/5.5-binaries/ and download net-snmp-5.5.0-2.x64.exe. Run the downloaded file, making the following selections on the Choose Components screen of the Net-SNMP 5.5 Setup Wizard: Expand Net-SNMP Agent Services and select With Windows Explorer Net-SNMP Trap Services Perl SNMP Modules All binaries are created in the installed folder specified in the Choose Default Location screen of the setup wizard.

2. Register (or unregister, if required) the Net-SNMP Services by running the appropriate .bat file, all of which are located in the Net-SNMP installation folder. [+] Show files : To Do This ... To This Service ... Run this File Register Net-SNMP agent registeragent.bat Net-SNMP trap handler registertrapd.bat Unregister Net-SNMP agent unregisteragent.bat Net-SNMP trap handler unregistertrapd.bat After registration, the files are located in the following locations: [+] Show file locations Note: The file locations given in the table are by default, based on the default location specified in Step 1. Files Location snmpd.conf C:\usr\etc\snmp\snmpd.conf snmpd.conf (persistent) C:\usr\snmp\perisist\snmpd.conf Is the folder actually called "perisist" or "persist"? snmptrapd.conf C:\usr\etc\snmp\snmptrapd.conf Log files C:\usr\log\snmpd.log

3. Modify the Net-SNMP configuration file, snmpd.conf to define system-specific parameters, as follows: [+] Show steps To open the UDP port through which SCS can communicate with the SNMP master agent, add the following line to the configuration file: agentaddress udp:<port_num> where <port_num> is any valid port number. This port must not be used by any other process. You can check if the port has been opened successfully by running the following command: C:\>netstat –aon | findstr <port_num> If it shows the port, then the port is open. To enable agentx functionality and open the agentX port, add the following lines to the configuration file: Master agentX agentxsocket tcp:<host_address>:<port_num> where: <host_address> is the IP address of the host on which Net-SNMP is running. <port_num> is any valid port number. This port must not be used by any other process. Configure the SNMP version. Do one of the following: For SNMP v1 or SNMP v2, add the following lines to the configuration file: rocommunity public rwcommunity private These parameters are similar to the read_community and write_community configuration options in an SNMP master agent. For SNMP v3, add the following lines to the configuration file: # VACM configuration entries rwuser <username> # create and add a user createUser <username> MD5 <md5_password> <DES des_password> You can check if SNMP v3 has been configured successfully by running the following command: C:\>snmpget -v3 -u <username> -n "" -l authNoPriv -a MD5 -A <md5_password> <localhost> sysUpTime.0 If any output is displayed, then SNMP v3 has been successfully configured. You can also create another user based on the initial user by running the following command: C:\>snmpusm -v3 <username> -u initial -n "" -l authNoPriv -a MD5 -A <md5_password> <localhost> create <newuser> initial

4. Configure the MIB Browser for the version of SNMP you are using. Do one of the following: [+] Show settings Need list of field names in, or screen shots from, Genesys Administrator (or GAX if supported). Configuration Manager is no longer mentioned in this document. For SNMP v1 or SNMP v2, set the following: SNMP version Number of port on which snmpd is running For SNMP v3, set the following: SNMP version User profile name Security user name Number of SNMP port on which on which snmpd is running Authentication protocol Privacy protocol

5. Modify the Net-SNMP configuration file, snmpd.conf, to define where SNMP traps are to be sent, as follows: [+] Show changes For SNMP v1 traps, add the line: trapsink <transport>:<host_address>:<port> where: <transport> can be udp or tcp. <host_address> is the IP address of the host to where SNMP traps are to be sent. <port> is the SNMP port on which traps are to be received. For SNMP v2 traps, add the line: trap2sink <transport>:<host_address>:<port> where: <transport> can be udp or tcp. <host_address> is the IP address of the host to where SNMP traps are to be sent. <port> is the SNMP port on which traps are to be received. For SNMP v3 traps, add the line: trapsess -v 3 –u <username> -l authNoPriv -Ci -a MD5 -A "<authentication_password>" <host_address>:<port> where: <host_address> is the IP address of the host to where SNMP traps are to be sent. <port> is the SNMP port on which traps are to be received.
