Introduction

The auto discovery feature helps detect devices on the network. The device view presents information about all network devices in the system, allowing users to quickly know their basic operating status. The resource details page displays comprehensive device information, including an overview, device details, alarm information, monitoring details, and group information. You can also perform configuration tasks, such as modifying device labels and access parameter templates.

Feature usage guide

Applicable scenarios

On the device view page, you can view the device status, device label, IP address, device category, and device model. The resource details page displays an overview, device details, alarm information, monitoring details, and group information. You can also modify basic device information and access parameter templates through the device details page.

On the auto discovery page, you can view the task name, task status, start date, and last execution time.

Prerequisites

·     Log in to Unified Platform with an operator account with device management permissions. If the operator lacks the permission, navigate to the Role Management > Roles page in the left navigation tree under the System tab and assign permissions to the operator.

·     The devices to be managed can communicate with the system.

·     To read information from a device, configure a correct SNMP parameter template. To deploy configuration to a device, configure SSH or Telnet parameters on the device.

Example: Configuring device management

After you add a device to the system, you can monitor and configure the device.

Procedures

Add a network device

1.     Log in to Unified Platform.

2.     On the top navigation bar, click Management. From the left navigation pane, select Device Management > Device Views, as shown in Figure 1.

Figure 1 Device Views page

 

3.     Click Add. The Add Device page opens, as shown in Figure 2.

Figure 2 Adding a device

 

4.     In the Basic Information area, specify the IP address, device label, and login type of the device, as shown in Figure 3.

¡     IP Address: Enter the IP address of the network device. An IPv4 address is in dotted decimal notation, and cannot be loopback address 127.0.0.1 or local domain name localhost. An IPv6 address is in colon hexadecimal notation. In this example, 192.167.1.120 is entered.

¡     Device Label: Enter the device label of the network device. If you do not enter a device label, the system reads the sysname as the device label. The device label can contain a maximum of 64 characters. If the entered device label is different from the sysname, the device can be managed successfully, and the entered device label is displayed on the page. In this example, no device label is entered.

¡     Device Login Type: Select a login type. Options include Telnet (default), SSH, and None. In this example, the default is used.

¡     Enable the device to send SNMP traps to the system: Select whether to have the device to send traps (SNMP notifications) to the system. In this example, this option is selected (the default).

¡     Support Ping Operation: Select whether to ping the device from the system before adding the device to the system. If the device cannot be pinged or does not support ping operations, it cannot be added to the system. If you do not select this option, the device is added to the system without being pinged. In this example, this option is selected (the default).

¡     Add the device regardless of the ping result: Select whether to add the device to the system even if it cannot be pinged. In this example, this option is not selected (the default).

Figure 3 Configuring basic information

 

5.     Configure SNMP settings. Telnet, SSH, and NETCONF settings can be left blank. In this example, only SNMP settings are configured, and Telnet, SSH, and NETCONF settings are left blank.

a.     Click Select. The Select SNMP Template window opens, as shown in Figure 4.

Figure 4 Select SNMP Template window

 

b.     Select an existing template, or click Add to add a template and then select the new template. In this example, a new template is added and selected, as shown in Figure 5.

-     Template Type: This parameter displays networkSnmp and is not configurable.

-     Name: Enter a template name. The template name can contain a maximum of 50 characters. Valid characters include Chinese characters, letters, digits, spaces, underscores (_), hyphens (-), colons (:), and dots (.). In this example, the template name is NetworkSNMP.

-     Description: Enter a description for the template, a string of up to 200 characters. In this example, this parameter is left blank.

-     Type: Select a version for the SNMP template. The default version is SNMPv1. In this example, SNMPv2c is used. Most devices support SNMPv1, SNMPv2c, and SNMPv3. Support for the versions depends on the device model.

-     Read-Only Community String: Communities with read-only permissions can only query devices. You must specify the read-only community string, the read-write community string, or both. You can modify the read-only community string based on the device type. The default is public. In this example, the default is used.

-     Read-Write Community String: Communities with read/write permissions can configure devices. The default is private. In this example, the default is used.

-     Timeout (1-50): Enter the maximum amount of time that the system can wait for a response from the device, in seconds. The default is 4 seconds. In this example, the default is used.

-     Retry Times: Enter the maximum number of retries that can be performed by the system when a communication failure occurs with the device. The default is 3. In this example, the default is used.

-     Port: Enter the port number used to log in to the device through SNMP. The default is 61.

-     Management Station: Select a management station for the device. This parameter appears only if you have installed the Region component. By default, a device belongs to the local management station.

-     Resource Group: Select a resource group. The SNMP template will inherit the permissions of the resource group. In this example, no resource group is selected.
