1 SNMP Configuration
About This Chapter
The Simple Network Management Protocol (SNMP) is a standard network management protocol
widely used on TCP/IP networks. It uses a central computer (a network management station)
that runs network management software to manage network elements. There are three SNMP
versions, SNMPv1, SNMPv2c, and SNMPv3. You can configure one or more versions, if
needed.
1.1 Introduction to SNMP
SNMP provides a set of standard protocols for the communication between the network
management station (NM station) and devices, allowing the NM station to normally manage
devices and receive alarms reported by the devices.
1.2 Configuring a Device to Communicate with an NM Station by Running SNMPv1
After SNMPv1 is configured, a managed device and an NM station can run SNMPv1 to
communicate with each other. To ensure normal communication, you need to configure both
sides. This section describes only the configurations on a managed device (the agent side). For
details about configurations on an NM station, see the pertaining NM station operation guide.
1.3 Configuring a Device to Communicate with an NM Station by Running SNMPv2c
After SNMPv2c is configured, a managed device and an NM station can run SNMPv2c to
communicate with each other. To ensure normal communication, you need to configure both
sides. This section describes only the configurations on a managed device (the agent side). For
details about configurations on an NM station, see the pertaining NM station operation guide.
1.4 Configuring a Device to Communicate with an NM Station by Running SNMPv3
After SNMPv3 is configured, a managed device and an NM station can run SNMPv3 to
communicate with each other. To ensure normal communication, you need to configure both
sides. This section describes only the configurations on a managed device (the agent side). For
details about configurations on an NM station, see the pertaining NM station operation guide.
1.5 SNMP Configuration Examples
This section provides several configuration examples of SNMP. The configuration roadmap in
the examples will help you understand the configuration procedures. Each configuration
example provides information about the networking requirements, configuration notes, and
configuration roadmap.

1.1 Introduction to SNMP
SNMP provides a set of standard protocols for the communication between the network
management station (NM station) and devices, allowing the NM station to normally manage
devices and receive alarms reported by the devices.
1.1.1 SNMP Overview
Get and Set operations can be performed on a managed device that runs the SNMP agent to
manage device objects by NM stations These objects are uniquely identified in the Management
Information Base (MIB).
As network services develop, more devices are deployed on existing networks. The devices are
not close to the central equipment room where a network administrator works. When faults occur
on the remote devices, the network administrator cannot detect, locate or rectify faults
immediately because the devices do not report the faults. This affects maintenance efficiency
and greatly increases maintenance workload.
To solve this problem, equipment vendors have provided network management functions in
some products. These functions allow the NM station to query the status of remote devices, and
devices can send alarms to the NM station in the case of particular events.
SNMP operates at the application layer of the IP suite and defines how to transmit management
information between the NM station and devices. SNMP defines several device management
operations that the NM station can perform and allows devices to send alarms to notify the NM
station of device faults.
An SNMP-managed network consists of three components: NM station, agent, and managed
device. The NM station uses the MIB to identify and manage device objects. The operations
used for device management include GetRequest, GetNextRequest, GetResponse, GetBulk,
SetRequest, and notification from the agent to the NM station. The following sections give details
on the components, MIB, and operations.
SNMP Components
SNMP device management uses the following three components:
lNM station: sends various query packets to query managed devices and receives alarms
from these devices.
lAgent: is a network-management process on a managed device. An agent has the following
functions:
–Receives and parses query packets sent from the NM station.
–Reads or writes management variables based on the query type, and generates and sends
response packets to the NM station.
–Sends an alarm to the NM station when triggering conditions defined on each protocol
module corresponding to the alarm are met. For example, the system view is displayed
or closed, or the device is restarted.
lManaged device: is managed by an NM station and generates and reports alarms to the NM
station.
Figure 1-1 shows the relationship between the NM station and agent.

MIB
SNMP uses a hierarchical naming convention to identify managed objects and to distinguish
between managed objects. This hierarchical structure is similar to a tree with the nodes
representing managed objects, Figure 1-2 shows a managed object that can be identified by the
path from the root to the node representing it.

B
As shown in Figure 1-2, object B is uniquely identified by a string of numbers, {1.2.1.1}. Such
a number string is called an Object Identifier (OID). A MIB tree is used to describe the hierarchy
of data in a MIB that collects the definitions of variables on the managed devices.
A user can use a standard MIB or define a MIB based on certain standards. Using a standard
MIB can reduce the costs on proxy deployment and therefore reduce the costs on the entire
network management system.
SNMP Operations
SNMP uses Get and Set operations to replace a complex command set. The operations described
in Figure 1-3 can implement all functions.

Operation Function
GetRequest Retrieves the value of a variable. The NM station sends the
request to a managed device to obtain the value of an object
on the device.
GetNextRequest Retrieves the value of the next variable. The NM station
sends the request to a managed device to obtain the status
of the next object on the device.
GetResponse Responds to GetRequest, GetNextRequest, and
SetRequest operations. It is sent from the managed device
to the NM station.
GetBulk Request from the NMS-to-agent, equaling continuous
GetNextRequest operations.
SetRequest Sets the value of a variable. The NM station sends the
request to a managed device to adjust the status of an object
on the device.
Trap Reports an event to the NM station.
1.1.2 SNMP Features Supported by the S9300&S9300E
This section compares SNMP versions in terms of their support for features and usage scenarios.
Use it as a reference when you select the SNMP version during network deployment.
The S9300&S9300E supports SNMPv1, SNMPv2c, and SNMPv3. Table 1-2 lists the features
supported by SNMP, and Table 1-3 shows the support of different SNMP versions for the
features. Table 1-4 describes the usage scenarios of SNMP versions, which will help you choose
a proper version for the communication between an NM station and managed devices based on
the network operation conditions.

NOTE
When multiple NM stations using different SNMP versions manage the same device in a network,
SNMPv1, SNMPv2c, and SNMPv3 can all be configured on the device for its communication with all the
NM stations.
Table 1-2 Description of features supported by SNMP
Feature Description
Access control Restricts a user's device administration rights.
It gives specific users the rights to manage
specified objects on devices and therefore
provides fine management.
Authentication and encryption Authenticates and encrypts the packets
transmitted between the NM station and
managed devices. This prevents data packets
from being intercepted or modified,
improving data sending security.
Error code Identifies particular faults. An administrator
uses error codes to quickly locate and rectify
faults. The more error codes received, the
more they help an administrator in device
management.
Trap Sent from managed devices to the NM
station. These traps allow an administrator to
discover device faults immediately.
After sending traps, the managed devices do
not require the acknowledgement from the
NM station.
Inform Sent from managed devices to the NM
station.
The managed devices require the
acknowledgement from the NM station after
sending informs. If a managed device does
not receive an acknowledgement after
sending an inform, it will resend the inform
to the NM station and generate alarm logs.
Even if the NM station restarts, it can still
synchronize the informs sent during the
restart process.
If the managed device does not receive an
acknowledgement from the NM station after
sending an inform, it will store the inform in
its memory. In this regard, using informs may
consume lots of system resources.
