SNMPv3 Understanding

 

Hi All,

I'm struggling a little bit with SNMPv3 concept. I understand how to create views, groups and users but not understanding how those get used. For example, on R1 I create 1 read only view, 1 group with that same view and assign 1 user to that group and the authentication of course. Does this mean another box trying to query R1 would have to have send the query with the username in the query so R1 knows what group this user belongs to and therefore what rights this user has?

 

NMS Box ----------------------R1

 

Does R1 use these users and groups when it generates traps or sends any type of info to the management server? I guess I'm not understanding the grand scheme of things and how these groups and users get used? Any help would be appreciated.
