Reference from http://www.zabbix.org/wiki/ConfigureSnmptrapsCentos6_RHEL6).

Install Packages

# yum install net-snmp-utils
# yum install net-snmp-perl
# yum install snmptt

Note: perl-Net-SNMP will be installed together with snmptt

Configure Zabbix Server

# vi /etc/zabbix/zabbix_server.conf
StartSNMPTrapper=1
SNMPTrapperFile=/var/log/snmptt/snmptt.log

Configure snmptrapd

# vi /etc/snmp/snmptrapd.conf
traphandle default /usr/sbin/snmptthandler
authCommunity   log,execute,net public

Configure snmptt

# vi /etc/snmp/snmptt.ini
translate_log_trap_oid = 2
net_snmp_perl_enable = 1
date_time_format = %H:%M:%S %Y/%m/%d
log_file = /var/log/snmptt/snmptt.log
log_system_enable = 1

Install TelcoBridges snmptt.conf:

# wget http://download.distribution.telcobridges.com/zabbix/snmptt.conf
# cp snmptt.conf /etc/snmp/snmptt.conf

Install MIBs

Retrieve the following MIB files from TelcoBridges:

# wget http://download.distribution.telcobridges.com/mibs/TB-MIB-2014.mib
# wget http://download.distribution.telcobridges.com/mibs/rfc-2495.mib
# wget http://download.distribution.telcobridges.com/mibs/rfcperfhist.mib

Get the NET-SNMP mib path on your system:

# snmptranslate -Dinit_mib .1.3 2>&1 |grep MIBDIR
 init_mib: Seen MIBDIRS: Looking in '/root/.snmp/mibs:/usr/share/snmp/mibs' for mib dirs ...

Copy the mibs files to the MIBDIRS path: For example, if your MIBDIRS path is usr/share/snmp/mibs:

# cp TB-MIB-2014.mib /usr/share/snmp/mibs/.
# cp rfc-2495.mib /usr/share/snmp/mibs/.
# cp rfcperfhist.mib /usr/share/snmp/mibs/.

Configure snmp.conf:

# vi /etc/snmp/snmp.conf
mibs +ALL

Start services

# chkconfig snmptt on
# chkconfig snmptrapd on
# service snmptrapd start
# service snmptt start

Open firewall
