Hi hhi - this might make things a little clearer:
- Name = the name of the credential in the Workspace Studio (not passed to the device)
- Username = the username as defined in the Cisco "snmp-server user ..." command
- Context = the context used in the Cisco "snmp-server group ..." command.
- Views - are contained in groups;
- 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
- Users define the username and the authentication and encryption parameters.
So, to create the user "greg" (my favorite), an using md5 auth password of "gregsauthpwd" and des encryption with a password of (you guessed it) "gregsencpassword", you would enter the following commands on your Cisco IOS device:
// define the view - we are making one called gregsview that can see everything in mib-2
snmp-server view gregsview mib-2 included
// Create a group that uses the new view for read and write, and specify that it must use SNMPv3 with both authentication and privacy turned on, and a context name of "gregscontext"
snmp-server group gregsgroups v3 priv context gregscontext read gregsview write gregsview
// and finally create the user
snmp-server user greg gregsgroup v3 auth md5 gregsauthpassword priv des gregsencpassword
In the Workspace Studio, you would define a credential to talk to this device like the following:
Hope this clears things up,
Thanks for the complete explanations, unfortunately I'm still unable to reach the device... :-(
I tried several combinations, still not reachable.
What is "Password is key" for by the way?
I guess also Read/Write is for a credential that can also write on the device? On my current, it is only read.
If you are in a time crunch, open a support ticket here. In order to receive technical support, you will need to be current on your SolarWinds maintenance. Complete the form. You will not be able to upload your Orion diagnostics, but you will receive an email back that allows you to upload diagnostics.
I tried a lot today and finally found a config that works:
access-list 1 permit host NMS-HOST
snmp-server view orionview mib-2 included
snmp-server group oriongroup v3 priv read orionview access 1
snmp-server user orion oriongroup v3 auth sha AUTH-KEY priv aes 128 PRIV_KEY
The access is read-only and limited to NMS-HOST.
