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.
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 and SNMPv2c. 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.
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, for example, VPNs. |
Procedure
- Click Maintenance to open the maintenance page.
- Click in the left navigation tree to open the SNMP Agent configuration page
- Set the SNMP Agent parameters, including SNMP Agent status,
SNMP Agent version, community name, and access rights. For description
of the parameters, see Table 2.
Table 2 SNMP Agent configuration items Parameter
Description
SNMP Indicates the SNMP Agent status:- ON: SNMP Agent is enabled.
- OFF: SNMP Agent is disabled.
To manage devices using the NMS, enable the SNMP Agent function.
Version number Indicates the SNMP version on the device.
SNMPv1 and SNMPv2c are supported. Choose one or multiple versions. Ensure that the SNMP versions on the device and on the NMS are the same.
Community Name Indicates the read/write community name of SNMPv1 and SNMPv2c.
This is the password that the NMS uses to perform the read and write operations on the SNMP agent. The password configured on the SNMP agent must be the same as that configured on the NMS.
Confirm Community Name The confirm community name must be the same as the community name.
Community Right Indicates the access right of the community name.- Read-only: The NMS can only read data on the device.
- Read-write: The NMS can read and write data on the device.
- Click Apply to complete the configuration.
