When modifying user property for SNMP, users need to set the password again if SNMPv3 uses a privacy protocol - IBM Flex System

Resolving The Problem

Source

RETAIN tip: H206361

Symptom

The Integrated Management Module (IMM) Simple Network Management Protocol (SNMP) password needs to be reset after changing SNMP user account properties.

The issue is seen in this circumstance:

1. Log into the IMM web interface and choose IMM Management, Users.
   
   
2. On the User Credentials page, click Create User and assign a user name and password.
   
   
3. On the Authority page, click Next to assign Supervisor authority. Check the checkboxs for Use an authentication protocol and Use a privacy protocol, then fill in passwords.
   
   
4. In Access type, choose Set. Under the Linux client, use the 'snmpwalk' command to retrieve node information. It will return the node information successfully.
   
   
5. Go back to the browser and choose IMM Management, Users.
   
   
6. Select the user just created to open the pop-up User Properties window. Under the SNMPv3 tab, change Access type to Set.
   
   
7. Under the Linux client, using the snmpwalk command to retrieve the node information will fail.
