UNABLE TO INTEGRATE SRX TO SNMPV3 SERVER

Problem Description –

 While trying to Poll SRX using SNMPv3 server no SNMP response is received from Juniper SRX.Inspite of trying multiple browsers (iReasoning, solarwinds etc ), response is not received on SNMP V3 management application server.However,the polling and its reponse works well on changing SNMP version to 2 (SNMP v2) .Multiple SNMP keys have been tried,however traces received in SRX show authentication failure.

Solution –

While configuring SNMPv3 on SRX we should use “authentication-password” and not “authentication-key“.

The incorrect command format is –
Set snmp v3 usm local-engine user TEST authentication-md5 authentication-key <password>

 

 

The Correct command format should be –
Set snmp v3 usm local-engine user TEST authentication-md5 authentication-password <password>

 

 

PS – If we specify authentication-key then an external tool is required to generate the key and the feed it to SNMPv3 browser.
