VIEW CONFIG
SNMPv3 denes the concept of Management Information Base (MIB) views in RFC 3415, View-based Access
Control Model (VACM) for SNMP. MIB views provide an agent better control over who can access specic
branches and objects within its MIB tree. A view consists of a name and a collection of SNMP object
identiers, which are either explicitly included or excluded. Once dened, a view is then assigned to an
SNMP group - see SNMP Group Cong.
Once a view has been created, create a rule for the view.
Item Description
Rule Also referred to as the ‘”Type.” Species whether to include or exclude the view subtree
or family of subtrees from the MIB view.
MIB subtree OID Enter an OID string for the subtree to include or exclude from the view. An OID string is
256 characters in length. For example, the system subtree is specied by the OID string
1.3.6.1.2.1.1.
Subtree mask Provide the OID mask here.
RMON CONFIG
Remote Monitoring (RMON) is a standard monitoring specication that enables various network monitors
and console systems to exchange network-monitoring data. RMON is the most important expansion of
the standard SNMP. RMON is a set of MIB denitions used to dene standard network monitor functions
and interfaces, enabling the communication between SNMP management terminals and remote monitors.
RMON provides a highly ecient method to monitor actions inside the subnets.
MIB of RMON consists of 10 groups. The Intellinet Network Solutions 24-Port Gigabit Ethernet PoE+ Web-
Managed Switch with 4 Gigabit Combo Base-T/SFP Ports supports the most frequently used groups 1, 2, 3
and 9:
• Statistics: Collects Ethernet, Fast Ethernet, and Gigabit Ethernet statistics on an interface.
• History: Collects a history group of statistics on Ethernet, Fast Ethernet, and Gigabit Ethernet
interfaces for a specied polling interval.
• Alarm: Monitors a specic MIB object for a specied interval, triggers an alarm at a specied value
(rising threshold), and resets the alarm at another value (falling threshold). Alarms can be used with
events; the alarm triggers an event, which can generate a log entry or an SNMP trap.
• Event: Determines the action to take when an event is triggered by an alarm. The action can be to
generate a log entry or an SNMP trap.
RMON is specied as part of the MIB in RFC1757 as an extension of the SNMP.
