Can't query S5700 from Solarwind NPM

536 0 0 0 0

When trying to query Huawei switch (configured for snmpv3 as bellow) via snmpv3 from Solarwinds NPM it doesn’t work saying Test failed.

First verify basic requirements and potential causes like the below ACL configured on SNMP-agent that is not matching:

Configure the destination ip address for receiving traps and error codes as follows:

snmp-agent target-host trap address udp-domain ip-address [ udp-port port-number | source interface-type interface-number ]

snmp-agent target-host inform address udp-domain ip-address [ udp-port port-number | source interface-type interface-number | [ vpn-instance vpn-instance-name ]

snmp-agent target-host trap ipv6 address udp-domain ipv6-address [ udp-port port-number | vpn-instance vpn-instance-name ] * params securityname security-name [ v3 [ authentication | privacy ] | private-netmanager | notify-filter-profile profile-name | ext-vb ] *

Even though checking the diagnostic information and discover this messages:


the version of SNMP can be V3 so the version mismatch might not be real. 

Best practice will be to check this too, if this messages are discovered.

This issue is caused by the Privacy/Encryption algorithm on Solarwinds that is AES256.

To eliminate the problem change the Privacy/Encryption in Solarwinds from AES256 to AES128.
