SNMP

SNMP

Simple Network Management Protocol (SNMP) is a standard network management protocol widely used on TCP/IP networks. SNMP uses a central computer (a network management station) that runs network management software to manage network elements.

SNMP Global Settings

You can set global SNMP for the device.

Context

SNMP agent is an agent program on the managed device. The SNMP agent maintains information for the managed device, responds to the requests from the NMS, and sends management data to the NMS. Before the NMS manages a device through SNMP, the SNMP agent must be enabled on the device and a proper SNMP version needs to be selected.

A web system supports SNMPv1, SNMPv2c, and SNMPv3. The device and NMS must use the same SNMP version.

NOTE:

If a device is managed by multiple NMSs running different SNMP versions, all the SNMP versions need to be set on the device so that the device can communicate with these NMSs.

Table 2-27  Usage scenarios of SNMP

Version

Usage Scenario

SNMPv1

Applicable to small-sized networks that have simple and stable topologies, have low security requirements, or are not prone to attacks. For example, campus networks and small enterprise networks.

SNMPv2c

Applicable to medium- or large-sized networks that have low security requirements or are not prone to attacks, have high service traffic volume, and may be congested by traffic.

SNMPv3

Applicable to all networks, especially the networks having high security requirements. SNMPv3 allows only authorized administrators to manage the network. If the NMS and managed devices communicate over the public network, SNMPv3 is recommended.

Procedure

  1. Choose System Management > SNMP in the navigation tree to open the SNMP Global Settings page, as shown in Figure 2-65.

    Figure 2-65  SNMP Global Settings

    Table 2-28 describes parameters on the SNMP Global Settings page.

    Table 2-28  SNMP Global Settings

    Parameter

    Description

    SNMP agent

    Indicates whether the SNMP agent is enabled.

    SNMP version

    Indicates the SNMP version on the device. By default, SNMPv3 is supported. Choose one or multiple versions. Ensure that the SNMP versions on the device and on the NMS are the same.

    NOTE:

    Using SNMPv1&v2c has potential security risks. SNMPv3 is recommended.

    Local engine ID

    This value is automatically generated by the system or set by you.

    Device position

    Indicates the physical location of the device.

    When the Device Position field is empty, clicking Apply will display the factory settings of the device.

    Contact

    Indicates the contact information maintained on the device.

    When the Contact Information field is empty, clicking Apply will display the factory settings of the device.

  2. Set parameters.
  3. Click Apply to complete the configuration.

Community/Group Management

You can configure the SNMPv1 and SNMPv2c communities and SNMPv3 groups.

Context

The community/group management configurations vary with SNMP versions. After global SNMP settings are complete, configure the communities/groups. Table 2-29 lists the mappings between SNMP versions and configurations.

MIB View

You can restrict the NMS's rights to manage the device.

Context

A MIB view is a collection of all managed objects. The NMS manages devices by reading information from and writing information to the managed objects in the MIB. A MIB view defines the management information included in or excluded from the MIB view. Two implementation methods are available for the MIB view:
  • When the NMS manages most MIB objects on the managed device or some objects in the MIB view do not need to be managed by the NMS, the unmanaged objectives can be configured.
  • When the NMS manages a few MIB objects on the managed device or some objects in the MIB view are managed by the NMS with access restrictions, the objectives can be configured.

Procedure

  • Create a MIB view.
    1. Choose System Management > SNMP > MIB View in the navigation tree to open the MIB View page.
    2. Click Create to open the Create MIB View page, as shown in Figure 2-71.

Trap Settings

You can configure the trap function on the device.

Context

A trap is an alarm message sent from the managed device to the NMS to notify administrators of the network faults. After receiving a trap from a managed device, the NMS does not need to reply.

NOTE:

The web management system supports a maximum of 20 trap target hosts. When the number of trap target hosts to be configured exceeds the limit, the system displays a prompt message.

Procedure

  • Configure trap.
    1. Choose System Management > SNMP > Trap Settings in the navigation tree to open the Trap Settings page, as shown in Figure 2-73.

      Figure 2-73  Trap Settings
