Configuring SNMP v1 on IBM AIX

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, follow these steps:

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, it is necessary to change the symbolic link if it is not good. Look for the linkfile in /usr/sbin

To verify 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 correct elements: /etc/snmpd.conf

logging         file=/usr/tmp/snmpd.log         enabled
logging         size=100000                     level=0
community       public
view            1.17.2          system enterprises view
trap            public          127.0.0.1       1.2.3   fe      # loopback
#snmpd          maxpacket=1024 querytimeout=120 smuxtimeout=60
smux            1.3.6.1.4.1.2.3.1.2.1.2         gated_password  # gated
smux            1.3.6.1.4.1.2.3.1.2.2.1.1.2     dpid_password   #dpid
snmpd smuxtimeout=200 #muxatmd
smux 1.3.6.1.4.1.2.3.1.2.3.1.1 muxatmd_password #muxatmd

Restart the services

startsrc -s snmpd

startsrc -s aixmibd -a “-c public”

startsrc -s hostmibd -a “-c public”

startsrc -s snmpmibd -a “-c public”

Test directly on the AIX server

snmpinfo -v -m dump -c public hrProcessorLoad

the following results indicate successful configuration:.

#hrProcessorLoad.1 = 0
#hrProcessorLoad.2 = 0
#hrProcessorLoad.3 = 0
#hrProcessorLoad.4 = 0
