VACM_VIEW defaultView 1.3.6.1.4.1.2.6.191 - excluded -

is changed to included:

VACM_VIEW defaultView 1.3.6.1.4.1.2.6.191 - included -

Then restart all the snmp services:

stopsrc -s snmpd;stopsrc -s dpid2;stopsrc -s aixmibd;stopsrc -s hostmibd;stopsrc -s snmpmibd
startsrc -s snmpd;startsrc -s dpid2;startsrc -s aixmibd;startsrc -s hostmibd;startsrc -s snmpmibd

If you are not receiving data for CPU, memory, etc:

Ensure hostmibd, snmpmibd and aixmibd are not commented out in /etc/rc.tcpip

Ensure that snmp configuration allows connections from 127.0.0.1 with public community (or the appropriate community if you’ve changed that used by aixmibd away from the default.) (Note: the subdaemon’s actually connect to hostname “loopback” – so make sure that correctly resolves to 127.0.0.1)

Ensure aixmibd is running: lssrc -s aixmibd

Check /var/tmp/aixmibd.log to see whether aixmibd has correctly registered with the snmpd system, and for clues as to why not.

You need to run the IBM snmpd on a different port:

chssys -s snmpd -a '-p 1610'
stopsrc -s snmpd;stopsrc -s dpid2;stopsrc -s aixmibd
stopsrc -s hostmibd;stopsrc -s snmpmibd
startsrc -s snmpd;startsrc -s dpid2;startsrc -s aixmibd
startsrc -s hostmibd;startsrc -s snmpmibd

Install net-snmp daemon, or compile from source. For drive performance monitoring, ensure you compile with the option: –with-mib-modules=ucd-snmp/diskio. For example, enter:

./configure --prefix=/usr/local/net-snmp --with-mib-modules=if-mib --enable-mfd-rewrites --without-kmem-usage --enable-ipv6 --enable-embedded-perl --enable-shared --with-mib-modules=ucd-snmp/diskio --without-perl-modules

Add these lines to your snmpd.conf (the one used by the net-snmp snmp daemon, not the AIX snmpd.conf in /etc/)

# Proxy IBM Agent Requests for port number
proxy -v 1 -c public 127.0.0.1:1610 1.3.6.1.4.1.2.2.1.1.0
proxy -v 1 -c public 127.0.0.1:1610 1.3.6.1.4.1.2.2.1.1.1.0
# Proxy iftable(IF-MIB: Interface Names & Stats), iptable and ifalias
proxy -v 1 -c public 127.0.0.1:1610 .1.3.6.1.2.1

# Proxy RFC1213-MIB (Route Info)
proxy -v 1 -c public 127.0.0.1:1610 .1.3.6.1.2.1.4.21.1
# Proxy SysUptime (netsnmp doesn't work)
proxy -v 1 -c public 127.0.0.1:1610 1.3.6.1.2.1.25.1.1.0
# Proxy the SNMP Descr so OS shows up properly
proxy -v 1 -c public 127.0.0.1:1610 .1.3.6.1.2.1.1.1.0
proxy -v 1 -c public 127.0.0.1:1610 .1.3.6.1.2.1.1.2.0
# Proxy paging spaces
proxy -v 1 -c public 127.0.0.1:1610 .1.3.6.1.4.1.2.6.191.2.4.2.1

Lastly, start the new snmpd with the flags snmpd -I -interfaces, and you should be good to go.

./snmpd -I -interfaces

You should configure the net-snmp snmpd daemon to start on system boot.
