Do you have SNMPv3 configured on the switch?
To set up SNMPv3 on your device you will need to setup Views, Groups, and Users.
Views define what MIBs are available.
Groups determine what MIBs can be read or written to, in a given context.
Users are assigned to groups and determine the username and authentication & encryption parameters.
On your device:
//define your view: we'll use testview that can see everything in mib-2
snmp-server view testview mib-2 included
//Now create a group that uses the new view for read/write for SNMPv3
snmp-server group testgroup v3 priv context testcontext read testview write testview
//And create the user with md5 authentication and des encryption
snmp-server user test testgroup v3 auth md5 testauthpassword priv des testencpassword
Now your device should be configured with SNMPv3 credential. To map that to the application fields the above information would be setup in the application as follows:
Credential Name: Test credential
password=testauthpassword 'password is a key' is not checked.
Enccryption=testencpassword 'password is a key' is not checked.
It was unclear to me exactly which product this was for so I hope this helps you.
