SNMP for AIX is available in three versions: v1 , v2 and v3 .
To configure snmp V1 on an IBM Aix server from version 5.x onwards, follow the procedure below:
Stop services :
stopsrc -s aixmibd stopsrc -s hostmibd stopsrc -s snmpmibd stopsrc -s snmpd
Configure the version of snmp that will be used on your server:
To do this you need to change the symbolic link if it is not good. See the link in /usr/sbin
To check the existing link, type :
cd /usr/sbin ls -l snm* Example :lrwxrwxrwx 1 root system 17 28 Apr 16:31 /usr/sbin/snmpd -> /usr/sbin/snmpdv1
To change the link, if it does not point to the correct snmpV1 version, type the following command:
snmpv3_ssw -1
Check that the configuration file contains the right elements: /etc/snmpd.conf
logging file=/usr/tmp/snmpd.log enabled
logging size=100000 level=0

Restart services

To test directly on the AIX server:
snmpinfo -v -m dump -c public hrProcessorLoad
if the result is the following then it works.
#hrProcessorLoad.1 = 0
#hrProcessorLoad.2 = 0
#hrProcessorLoad.3 = 0
#hrProcessorLoad.4 = 0
Make the change to the OS startup file
vi /etc/rc.tcpip
# Start up the hostmibd daemon start /usr/sbin/hostmibd "$src_running" "-c MyCommunity" # Start up the snmpmibd daemon start /usr/sbin/snmpmibd "$src_running" "-c MyCommunity" # Start up the aixmibd daemon start /usr/sbin/aixmibd "$src_running" "-c MyCommunity"
