CONFIGURING ACCESS FOR SNMP VERSION 3 CLIENTS
To configure management access for SNMPv3 clients, you need to first
create a user, assign the user to a group, create a view that defines the
portions of MIB that the client can read or write, and then create an access
entry with the group and view. The following example creates a user called
Steve, indicating that MD5 will be used for authentication, and provides the
passwords for both authentication and encryption. It assigns this user to a
group called “r&d.” It then creates one view called “mib-2” that includes
the entire MIB-2 tree branch, and another view that includes the IEEE
802.1d bridge MIB. In the last step, it assigns these respective read and
read/write views to the group called “r&d.”
