Figure 3.3 SNMP V3 Configuration Menu
Two SNMP “community entries” are generated: public (read-only
community), and a read-write community. Since a read-only community of
public is the default for all SNMP implementations, you are encouraged to
reconfigure the first community entry to a more secure value.
The “target entries” specify who may access the 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.
The “group entries” specify which version of SNMP to allow: 1.0 or 3.0 (user
security model).
The “access entry” specifies which version of SNMP to allow, the security
level (MD5 authorization encryption), and which views are accessible.
The “view entry” specifies which portion of the MIB is accessible or not
accessible. For example, it is possible to create a view to allow access to the
ATM Forum LES MIB from the EOC, and allow the entire MIB to be
accessible from an IP location.
The “user entry” applies to SNMP 3.0 only. This is where you configure the
MD5 authorization encryption password.
