snmpwalk timeout on CentOS 7.5 in DL380 Gen10

I have wantted to retrieve the hardware status via snmpwalk.
I had constructed SMA using the below user guide. However, I couldn't retrieve that.
Are there any other procedure needed?

Server : DL380 Gen10 (iLO5)
OS : CentOS 7.5

# rpm -ivh amsd-1.4.0-3066.82.rhel7.x86_64.rpm
# vi /etc/snmp/snmpd.conf
add "master agentx"
# systemctl start smad_rev
# systemctl start amsd_rev
# systemctl start snmpd
# snmpwalk -O vq -v 2c -c private localhost .1.3.6.1.4.1.232.6.2.6.4

I received the following message.
Timeout: No Response from localhost

Hello 

Thank you for wrinting your queries to us . 

For the below error we would like to suggest you the below steps 

Please use ILO dedicated NIC and not Shared NIC. 
test it with the newer net-snmp-utils-5.7.1-31.2.x86_64.rpm

Also please refer to the below artciles

@t-suda Make sure that iLO SNMP pass-through is disabled, go to iLO GUI, find it (I think it's under management) and disable that option. 

Then if the iLO IP is snmp-walked you will get the bare metal OIDs instead of iLO firmware passing the traffic to the underlying OS

Thank you for your response.

I'm sorry to be not able to find the iLO SNMP pass-through.

@t-suda  Hey sorry I think there maybe a misunderstanding on the iLO versio. From the screen shot I see that you're on release 4 of iLO. My post was about release 3 which is G7 and below of bare metal boxes. 

License Type iLO 3 Advanced
iLO Firmware Version 1.91 Oct 22 2018

Here's a screen shot of where that SNMP setting is for this iLO version:

Thank you for your explanation.

Okay, I've understood that.

However, there might be something that is instead of the SNMP pass-through in iLO5 as well.

I will try to look for it. Thank you.

Thank you for your advice.

However I already use the dedicated iLO NIC, and the newer snmp(net-snmp-utils-5.7.2-32.el7.x86_64).

And I tried the other versions of snmpwalk(1|3), but these command failured as with 2c.(Time out)

I've  executed them with the bellow simple configuration and procedure.

Is there any problem in this configuration?
