SNMP 3.0 requires the configuration of six data structures on the SNMP 3.0
menu (Figure 3.3), which is accessible from the SNMP Configuration menu.
Menu options are available to configure a default set of structures, which will
allow SNMP 1.0 or SNMP 3.0. Choose Option 3 on the SNMP 3.0
Configuration menu to set a simple default configuration.

Two SNMP “community entries” are generated: public (read-only

The “target entries” specify who may access the JetFusion IAD via SNMP.
The first entry, named “everyone,” allows access from the entire Internet.
Entries are added if an IP trap host is configured, or if EOC access is
configured. For example, if you want only IP addresses 1.2.3.0 through
1.2.3.255 to have SNMP access to the IAD, you will reconfigure the target
entry with the address of 1.2.3.0, and the mask 255.255.255.0. Note EOC
access is specified by the reserved IP address 255.255.255.255.
