Question 1


The user-based access control implemented by SNMPv3 is based on contexts and user names, rather than on IP addresses and community strings. It is a partial implementation of the view-based access control model (VACM).

Question 2


The first step we need to do when configuring an SNMPv3 user is to configure the server group to enable authentication for members of a specified named access list via the “snmp-server group” command. For example:

Router(config)# snmp-server group MyGroup v3 auth access snmp_acl

In this example, the SNMP server group MyGroup is configured to enable user authentication for members of the named access list snmp_acl.

    @Anonymous: In fact they are the same, only the answers were shuffled. But we removed one of them because they are the same. Thanks for your detection!

    for Q4:
    the auth option adds authentication to message integrity, using a username and password, with IOS storing password in hash

    the priv option is an addition secure level after auth. It causes the SNMP manager and agent to encrypt the entire SNMP packet for all SNMP messages, in addition to performing message integrity and authentication.

    Therefore, the command must use priv to enable encryption.
