A destination list is a list of internet destinations that can be blocked or allowed based on the administrative preferences for the policies applied to the identities within your organization. A destination is an IP address (IPv4), URL, or fully qualified domain name. You can add a destination list to Umbrella at any time; however, a destination list does not come into use until it is added to a policy.

The command "snmp-server user user-name group-name [remote ip-address [udp-port port]] {v1 | v2c | v3 [encrypted] [auth {md5 | sha} auth-password]} [access access-list]" adds a new user (in this case "andy") to an SNMPv3 group (in this case group name "myv3") and configures a password for the user.
In the "snmp-server host" command, we need to:
+ Specify the SNMP version with key word "version {1 | 2 | 3}"
+ Specify the username ("andy"), not group name ("myv3").
Note: In "snmp-server host inside ..." command, "inside" is the interface name of the ASA interface through which the NMS (located at 10.255.254.1) can be reached.
