After adding or modifying an SNMPv3 user via tmsh or iControl REST, SNMPv3 queries may return an unknown user name even though the user is correctly listed in tmsh list sys snmp users
SNMPv3 monitoring may report an unknown user name, causing a false report even though the user is present with mcps
- An SNMPv3 user is created, modified, or deleted via tmsh or iControl REST - SNMP configuration changes are issued in rapid succession with very little time interval in milliseconds - An SNMPv3 query is issued immediately after the configuration change
A slight delay between successive snmp configuration change queries. Now with this fix its resolved though
None
