Hello, 

I have issue with comunication via SNMPv3. SNMP 1 running correctly. I installed SNMP enabler and set the comunication of SNMPv3

SentAlerts.log view, that commvault sent Trap

7624  21e8  01/06 14:46:41 --- SNMP() -  simpanaAlertType: Event Viewer Events - Event Viewer Events simpanaWhenString: Wed, 06 Jan 2021 14:46:38 Central Europe Standard Time simpanaUserName: Not Applicable simpanaCommCell: czcommcell simpanaClient: czcommcell simpanaAppType: Not Applicable simpanaInstance: Not Applicable simpanaBackupSet: Not Applicable simpanaSubClient: Not Applicable simpanaJobId: 0 simpanaLibrary: Not Applicable simpanaMediaName: Not Applicable simpanaStoragePolicy: Not Applicable simpanaAlertMsg: Detected Criteria: Event Viewer Events , Event ID: 332510 , Monitoring Criteria: (Severity greater than or equal to Information;) , Severity: Minor , Job ID: Not Applicable , Event Date: Wed Jan  6 14:46:02 2021 , Program: MediaManager , Client: czcommcell.proact.local , Description: Validation/Resync of Deduplication Engine [SP_GlobalDDB_CZ-PHA_VMs_14] cannot proceed. Reason [DDB MA unreachable]. version: V3 destination: My Monitorig Server

but when try contact server via snmpwalk, so I have just messige about timeout.

In message of my Monitoring server Centos8 aren't mesage about conection, only, when I have wrong authhorizaton, so I have this message

 appliance snmptrapd[86121]: Authentication failed for User

But, when I am using correct authorization, so i have in message nothing.

I am using this cmd

snmpwalk -v3 -l authPriv -u User -a MD5 -A ‘PWD’ -x DES -X ‘PWD’ CommCell_IP 1.3.6.1.4.1.14604.2.2.0.106

Ports are opened and for testing I have Firewall down for both sides. 

Commcell running on Windows 10 and how I wrote on the top, SNMP1 running correctly.

Have someone any idea what is wrong?

Thank you
