In CMC you can configure authentication or encryption settings for each user using racadm command. Below commands can be used to configure SNMPv3 for a user

racadm config -g cfgUserAdmin -i -o cfgUserAdminSNMPv3Enable 1

racadm config -g cfgUserAdmin -i  -o cfgUserAdminSNMPv3AuthenticationType MD5

racadm config -g cfgUserAdmin -i  -o cfgUserAdminSNMPv3PrivacyType DES

Refer below link for supported values

hi Shine,

i am trying to run the same remotely using the below command and getting an error, could you please help....

Command : racadm.exe -r iDRAC-IP -u username -p password config -g cfgUserAdmin -I 4 -o cfgUserAdminSNMPv3Enable 1

ERROR: The syntax of the command specified is not correct.

Server Model: PowerEdge R430

iDRAC: 8

racadm version : 9.1.0

Hello Rajeesh-Tesco,

I have a couple of steps to try:

Can you SSH to the DRAC and run the command successfully there?

Can you try lower case:  -i 4 ?

Check if you're on the latest firmware:

BIOS 2.12.1, iDRAC 2.75.100.75

https://dell.to/3uAQy9t

If neither of those work; could you describe your goal and iDRAC8 firmware version and I'll check the command line guide.

Racadm CLI Guide (iDRAC7,8)

Thank you so much, the set command worked for enabling the SMNMPv3.

could you please share any documentation link if i can refer the new command sets to create user as well.

My requirement is to create a new user and enable SNMPv3 around 2000 hosts.

Hi Charles,

had checked the firmware and BIOS versions which is new as you mentioned. And was trying with "i" always but by mistake mentioned "I" while posting the query.

tried ssh to iDRAC and run the command and still got the same error and it got fixed with the Set command.

Thanks for your help

Thank you, the link helped me to meet the requirements. But, do we have an option to provide a one liner command to create user, enable, add privilege and all ?

You can have a file with below details and run mentioned command to configure users in one command

[iDRAC.Users.4]
UserName=username
Password=password
IpmiLanPrivilege=4
Privilege=0x1ff
SNMPv3AuthenticationType=SHA
SNMPv3Enable=Enabled
SNMPv3PrivacyType=AES
SolEnable=Enabled
Enable=Enabled

racadm -r -u -p set -t ini -f
