Starting in release 8.5.1, you can use Net-SNMP, instead of the Genesys SNMP Master Agent component, to implement SNMP functionality. Net-SNMP supports everything that Genesys SNMP Master Agent does. Genesys strongly recommends that you use the newest version of Net-SNMP Master Agent to make your SNMP configuration as robust as possible.
Net-SNMP and Genesys SNMP Master Agent can run in parallel on the same system, if the following conditions are met:
Only one SNMP Master Agent can be configured on each Solution Control Server (SCS).
The ports used by each SNMP Master Agent must be unique, and not used by any other application.
Solution Control Server and Local Control Agent support both implementations.
Installing Net-SNMP
If you choose to use Net-SNMP in addition to, or instead of, Genesys SNMP Master Agent, you must install Net-SNMP on all hosts where you need an SNMP Master Agent to reside. Use the following instructions, according to the operating system running on that host.
To install and configure Net-SNMP on Windows 64-bit Platforms, use the following steps:
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

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:
<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
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 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.
6. Prepare start and stop scripts to start and stop Net-SNMP as a service, as shown below. The path and filename of these scripts are stored in the annex of the SNMP Master Agent Application objects.
Start script, for example startsnmp.bat
net start "<netsnmp_servicename>"
net start "<netsnmptrap_servicename>"
Stop script, for example stopsnmp.bat
net stop "<netsnmp_servicename>"
net stop "<netsnmptrap_servicename>"
