Many companies avoid exposing certain machines to the Internet to reduce security risks, requiring offline methods for product activation and operations. This is a common practice today.
Imagine a scenario where you are using offline installations of Windows 10 and Windows 11 and you want to monitor them using SNMP. Before monitoring, you need to install SNMP.
If you try to execute a standard PowerShell command for the SNMP installation, as shown in the screenshot below, you will encounter an error.
Installing SNMP on the offline machine is slightly different from Windows 10 and Windows 11 connected to the internet.
I will show you how to install SNMP on offline Windows 10 using the FOD (Features on Demand) package. The same procedure applies to Windows 11.
Step 1: Download the Features on Demand ISO file
Since Windows 10 doesn’t have internet access, you’ll need to download the SNMP feature manually. Microsoft provides the Features on Demand (FOD) ISO file, which includes the SNMP client.
To download the FOD, you must have access to either MSDN or VLSC. If you don’t have access to MSDN or VLSC, drop me a comment or email, and I will share it with you.
Download the ISO file on a machine with Internet access, then transfer it to the offline Windows 10 machine.
Once the file is downloaded, mount it on your Windows 10 machine by right-clicking on the file and selecting Mount.
Step 2: Install SNMP client
Login to the offline Windows 10 machine, open File Explorer and navigate to the drive.
- Run PowerShell as administrator.
- Enter the following PowerShell command to run the FOD component for SNMP:
Dism /online /add-package /packagepath:"D:\Microsoft-Windows-SNMP-Client-Package~31bf3856ad364e35~amd64~~.cab"
- Run the following command to install the SNMP client:
Dism /online /Add-Capability /CapabilityName:"SNMP.Client~~~~0.0.1.0"
Now, if you open the Services applet (services.msc), you will see that the SNMP Service is running, which wasn’t the case before.
Step 3: Configure SNMP
Since SNMP is installed, it’s time to configure it. If you close the Services applet (services.msc), open it again to continue.
- Navigate to SNMP Service, right click on it, and then click Properties.
- Click on the Security tab to configure the community string and ACL.
- Click on Add… under Community to create a community string. In my case, the community string is called prtg.
- Select Accept SNMP packets from these hosts and click Add… to add the IP of your NMS (Network Monitoring Solution). In my case, the IP is 192.168.88.245 which is my PRTG Core Server. This means the Windows machine will only accept SNMP communication coming and going to my NMS.
- Click Apply and OK and you are done.
That’s it! Enjoy monitoring!

SNMP (
Simple Network Management Protocol
) — это классический протокол для мониторинга и сбора информации о сетевых устройствах (сервера, сетевое оборудование, рабочие станции, принтеры и т.д.). Протокол SNMP довольно легкий, быстрый, для передачи данных использует UDP порты 161 и 162. В этой статье мы рассмотрим, как установить и настроить службу SNMP в Windows Server 2022/2019 и Windows 10/11.
Содержание:
- Установка службы SNMP в Windows Server 2022/2019
- Установка SNMP агента в Windows Server Core
- Установка службы SNMP в Windows 10/11
- Настройка службы SNMP в Windows Server и Windows 10/11
Установка службы SNMP в Windows Server 2022/2019
В Windows Server службу SNMP можно установить с помощью Server Manager.
Выберите Add roles and features -> Features. Выберите SNMP Service (если нужно отметьте также SNMP WMI Providers).
Служба SNMP WMI Provider позволяет опрашивать SNMP устройство через WMI.
Нажмите Next -> Install и дождитесь окончания установки.
Установка SNMP агента в Windows Server Core
В Windows Server Core можно установить SNMP с помощью веб-интерфеса Windows Admin Center и PowerShell.
Если вы используете Windows Admin Center, подключитесь к хосту Windows Server, выберите Roles and Features -> SNMP Service.
Т.к. в Windows Server Core отсутствует графический интерфейс, а для его управления используется командная строка, вы можете установить службу SNMP из командной строки PowerShell.
Для установки ролей в Windows Server из PowerShell используется командлет Install-WindowsFeature.
Проверьте, что служба SNMP не установлена:
Get-WindowsFeature SNMP*
Установите роль SNMP и WMI провайдер:
Install-WindowsFeature SNMP-Service,SNMP-WMI-Provider -IncludeManagementTools
Проверьте, что службы SNMP запущены:
Get-Service SNMP*
В нашем примере SNMP служба запущена, а SNMPTRAP остановлена.
Установка службы SNMP в Windows 10/11
Вы можете использовать службу SNMP не только в Windows Server, но и в десктопных редакциях Windows 10 и 11.
В Windows 10/11 служба SNMP, вынесена в отдельный компонент Feature On Demand (как RSAT и OpenSSH).
Вы можете установить SNMP через панель Settings. Перейдите в Apps -> Optional features -> Add an optional feature -> View features.
В списке доступных компонентов выберите Simple Network Management Protocol (SNMP) и WMI SNMP Provider. Для начала установки нажмите Next (понадобится интернет подключение к серверам Microsoft).
Для установки службы SNMP через PowerShell, используйте команду:
Add-WindowsCapability -Online -Name SNMP.Client~~~~0.0.1.0
Для установки службы SNMP без подключения к интернету, вам понадобится скачать ISO образ Windows 10/11 Features on Demand из личного кабинета на сайте лицензирования Volume Licensing Service Center (VLSC).
Для офлайн установки службы SNMP с такого ISO образа используется команда:
Add-WindowsCapability -Online -Name SNMP.Client~~~~0.0.1.0 -LimitAccess -Source \\msk-fs01\Distr\Windows-FOD\Win11\
Настройка службы SNMP в Windows Server и Windows 10/11
Вы можете настроить параметры службы SNMP в консоли services.msc. Найдите службу SNMP Services в списке и откройте ее свойства.
Обратите внимание, что у службы SNMP есть несколько дополнительных вкладок:
- Agent
- Traps
- Security
На вкладке Agent указывается базовая информация об устройстве (контакты администратора, местоположение). Здесь же можно указать тип информации, который может отправлять данное устройство при SNMP опросе.
В старых версиях протокола SNMP (SNMP v.1 и SNMP v.2) для авторизации пользователя используется строка сообщества (community string). На вкладке Security можно создать несколько строк подключения.
Можно выбрать один из пяти уровней доступа для сообщества:
- READ ONLY — позволяет получать данные с устройства;
- READ WRITE — позволяет получать данные и изменять конфигурацию устройства;
- NOTIFY — позволяет получать SNMP ловушки;
- READ CREATE – позволяет читать данные, изменять и создавать объекты;
- NONE
Вы можете создать несколько community string. Для этого нужно задать имя и выбрать права/ Для мониторинга состояние сервера достаточно выбрать READ ONLY.
В списке Accept SNMP packets from these hosts можно указать имена/IP адреса серверов, которым разрешено опрашивать данное устройство. Если вы не хотите ограничивать список разрешенных устройств, оставьте здесь Accept SNMP packets from any hosts.
На вкладке Traps указываются адрес серверов, на который SNMP агент должен отправлять SNMP-ловушка (SNMP trap). SNMP Trap это широковещательный USP пакет, используемый для асинхронного уведомления менеджера (например, сообщение о критическом событии).
Не забудьте открыть в Windows Defender Firewall правила, разрешающие входящий и исходящий трафик для SNMP запросов и ловушек (TRAP). Нужные правила фаейрвола можно включить с помощью PowerShell.
В Windows Firewall есть несколько готовых правил для SNMP трафика:
Get-NetFirewallrule -DisplayName *snmp* |ft
- SNMPTRAP-In-UDP
- SNMPTRAP-In-UDP-NoScope
- SNMP-Out-UDP
- SNMP-In-UDP-NoScope
- SNMP-Out-UDP-NoScope
- SNMP-In-UDP
Можно включить все правила, или только определенное:
Get-NetFirewallrule -DisplayName *snmp* | Enable-NetFirewallRule
Get-NetFirewallrule SNMP-Out-UDP | Disable-NetFirewallRule
В списке служб Windows есть еще одна служба SNMP Trap. Она используется для получения сообщений от других SNMP агентов и пересылки на SNMP сервера (обычно это система мониторинга, опрашивающая устройства по SNMP, например PRTG или Zabbix).
Если вы настраиваете SNMP на Windows Server Core, вы не сможете использовать графический интерфейс службы SNMP для настройки ее параметров. Вместо этого придется вносить изменения в реестр с помощью PowerShell. Настройки службы SNMP хранятся в ветке реестра HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SNMP\Parameters.
Следующие команды зададут описание агента:
New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\services\SNMP\Parameters\RFC1156Agent" -Name "sysContact" -Value "[email protected]" -PropertyType REG_SZ
New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\services\SNMP\Parameters\RFC1156Agent" -Name "sysLocation" -Value "MSK_Datacenter1" -PropertyType REG_SZ
Для каждой ловушки SNMP придется создать отдельный ключ в HKLM\SYSTEM\CurrentControlSet\services\SNMP\Parameters\TrapConfiguration с именем community.
New-Item -Path "HKLM:\SYSTEM\CurrentControlSet\services\SNMP\Parameters\TrapConfiguration\public1"
Укажите разрешения для community:
New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\SNMP\Parameters\ValidCommunities" -Name "public1" -Value 4 -PropertyType DWord
Возможные значения:
- 1 — NONE
- 2 — NOTIFY
- 4 — READ ONLY
- 8 — READ WRITE
- 16 — READ CREATE
Для каждого community можно указать список серверов, с которых разрешено принимать запросы:
New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\SNMP\Parameters\PermittedManagers" -Name "1" -Value "server1.winitpro.ru" -PropertyType REG_SZ
Перезапустите службу SNMP для применения новых настроек из реестра:
Get-Service SNMP|Restart Service
Если нужно распространить эти SNMP настройки на множество компьютеров/серверов Windows в домене, используйте возможности внесения изменений в реестр через GPO.
Проверить работу службы SNMP можно с помощью утилиты snmpwalk (доступна в любом Linux дистрибутиве):
# snmpwalk -v 2c -c public1 -O e 192.168.13.122
В этом примере мы опросили наш Windows хост через версию протокола SNMPv2.
Утилита вернула базовыую информацию о хосте (syscontact, sysname, syslocation) и довольно большое количество информации о состоянии сервера Windows.
Протокол Simple Network Management Protocol (SNMP) используется для мониторинга, оповещения о событиях и управления устройствами в сети. Протокол состоит из набора стандартов по управления сетью, в том числе протокол прикладного уровня (Application Layer protocol), схемы базы данных и набор объектов данных. SNMP может получать различную информацию (время аптайма, счетчики производительности, параметры устройств и т.д.) от любых сетевых устройств: коммутаторов, серверов, маршрутизаторов или простых компьютеров, на которых установлен агент SNMP.
В Windows 10 служба SNMP доступна в виде отдельного компонента Windows и по умолчанию не устанавливается. Рассмотрим, как установить и настроить SNMP в Windows 10.
- Установка службы SNMP в WIndows 10
- Настройка службы SNMP в Windows 10
Содержание:
Установка службы SNMP в WIndows 10
Вы можете проверить, установлена ли в вашей системе служба SNMP с помощью PowerShell командлета Get-Service:
Get-Service -Name snmp*
Вы можете установить службу SNMP через панель управления. Перейдите в Панель управления\Все элементы панели управления\Программы и компоненты\ Включение или отключение компонентов Windows).
В списке компонентов выберите Simple Network Management Protocol (SNMP)/протокол, и WMI SNMP Provider / Поставщик WMI для SNMP (обеспечивает доступ к информации SNMP через интерфейсы Windows Management Instrumentation) и нажмите Ок.
Также вы можете установить службы SNMP из командной строки PowerShell:
Enable-WindowsOptionalFeature -online -FeatureName SNMP
Настройка службы SNMP в Windows 10
После установки службы SNMP должны запустится автоматически. Откройте консоль управления Services (services.msc). В списке службы должны появится две новые службы:
- SNMP Service – это основная служба SNMP агента, которая отслеживают активность и отправляет информацию;
- SNMP Trap — получает сообщения ловушки (trap messages) от локальных или удаленных агентов SNMP, и пересылает сообщения в управляющие программы SNMP, которые работают на этом компьютере.
Откройте свойства службы SNMP. Если она остановлена, запустите ее, нажав кнопку Start и измените тип запуска (Startup type) на автоматический.
Перейдите на вкладку Agent. Заполните поля contact и location (здесь вы можете указать контактное имя пользователя и местоположение компьютера), и выберите список сервисов, данные которых нужно собирать и отправить устройству мониторинга.
Доступны следующие типы сервисов:
- Physical
- Applications
- Internet
- End-to-end
- Datalink and subnetwork
Перейдите на вкладку Security. Здесь вы можете настроить различные параметры безопасности для различных серверов SNMP.
В списке Accepted community names перечислены имена сообществ, чьи SNMP узлы проходят аутентификацию для отправки SNMP-запросов на этот компьютер.
Community — это имя, которое обладает такими же функциями, как логин и пароль.
Нажмите кнопку Добавить и укажите имя Community и один из пяти уровней доступа (None, Notify, READ ONLY, READ WRITE, READ CREATE). READ WRITE – это максимальный уровень доступа, при которых сервер управления SNMP может вносить изменения в систему. В системах мониторинга обычно достаточно выбрать READ ONLY, при этом сервер мониторинга может только опрашивать систему, но не вносить изменения.
В нашем примере мы добавили комьюнити public с разрешениями READ ONLY.
Далее добавьте список серверов системы мониторинга (по DNS имени или по IP адресам), от которых вы хотите разрешить получать SNMP пакеты.
Совет. Вы можете выбрать опцию ‘Принимать пакеты SNMP от любого узла’/Accept SNMP packages from these hosts, но это не безопасно.
Сохраните изменения и перезапустите службу SNMP.
На этом настройка службы SNMP в Windows 10 по сути завершена. Если вам нужно включить SNMP сразу на множестве компьютеров, вы можете удаленно установить и настроить службы с помощью PowerShell или GPO.
