How to logon to EMC Isilon Storage Systems using SNMPv3 credentials?

[Johan van den H]

We want to be able to discover our EMC Isilon Storage Systems.
Our Isilon controllers have provided us with a SNMPv3 username and password and they have enabled SNMPv3 on the Isilon machines.

We entered the SNMPv3 username and password in ServiceNow and ran into an issue right away as ServiceNow offers some options when entering the credentials:

Authentication protocol
--None--
MD5
SHA

Privacy protocol
--None--
3DES
AES128
AES192
AES256
DES

Our Isilon controllers do not have a clue which protocols I should choose. I think I have tried all possible combinations but none resulted in SNMPv3 acces.

We were able to login using SNMPv2 credentials when SNMPv2 had been enabled by the Isilon controllers and run a successful discovery but we want to use SNMPv3 because it is more secure.

Can anyone point us in the right direction on how to solve this issue?

Googling tells me that Isilon uses AuthNoPriv security, our docs for that say the following:

 https://docs.servicenow.com/bundle/madrid-it-operations-management/page/product/discovery/concept/c_...

authNoPriv security:
Authentication protocol: Set
Privacy protocol: Leave blank
Authentication Key: Set
Privacy Key: Leave blank

 Does this help?

Thankyou for sharing the information Dave!

I tried the AuthNoPriv settings (with MD5 and SHA Authentication protocol settings) but both the discovery and the credential test come up negative.

The discovery shows error: SNMP probe timed out. Target is either unreachable or there are no valid credentials for it.

We already rechecked the login name and password combination.

EDIT 17-04-2019
We have done a SNMPwalk on the server which hosts our MIDserver and the connection with the Isilon servers was created without any problem and all data could be read.

The problem seems to be in how ServiceNow sets up the SNMPv3 login to Isilon.

Did you ever find a resolution to this? I am having the same issue.

Did you manage to resolve this and get discovery of the Isilon working?  Can you share your findings please?
