We have an older Dell EMC Networking N1524 on which I just updated the firmware to the latest version (6.6.0.24). I also want to monitor this switch, so I am attempting to configure SNMP v3 on it. However, I get an error when attempting to create the SNMP v3 user account.

Settings for the account:

• Group Name: DefaultRead
• Authentication Method: sha-key
• Password: (40-character string)
• Privacy: des-key
• Authentication Key: (40-charcter string)

With those settings in the Web UI, I get the error message:

"Error! Could not add the user priv key."

With those settings in the CLI, I get the error message:

"Incorrect input! Use 'snmp-server user [remote ] [ auth-md5 | auth-sha | auth-md5-key | auth-sha-key ] [ priv-des | priv-des-key ] ]'."

(I assure you I am using the syntax listed above.)

I have successfully configured all of the rest of the Dell EMC Networking N-series switches in our environment (including N1524 switches) with the exact same settings (using the web UI). The difference is that they are on older firmware versions (most are 6.2.x.x).

Did something break (or get deprecated) in the newer firmware? Or am I doing something wrong?
