Инструкции по входу для 3Com
Как зайти на страницу с настройками роутера 3Com
Веб-интерфейс роутера 3Com — это панель управления вашим роутером, в которой осуществляется сохранение и изменение всех настроек. Чтобы внести изменения в свою сеть, вам необходимо выполнить вход в свой роутер 3Com.
Необходимые условия для доступа к веб-интерфейсу 3Com
- Роутер 3Com
- Доступ к сети, либо по LAN-кабелю, либо по Wi-Fi
- Веб-браузер, который у вас наверняка есть.
Ниже приведены инструкции по подключению к интерфейсу роутера 3Com с целью его конфигурирования и диагностики.
1. Убедитесь, что вы подключены к роутеру 3Com
Чтобы получить доступ к страницам настройки вашего роутера 3Com, вам необходимо подключиться к его сети.
Поэтому, начните с подключения к сети либо по WiFi, либо по Ethernet-кабелю.
2. Откройте веб-браузер и перейдите по адресу 192.168.1.1
Откройте браузер и в поле адреса введите IP-адрес роутера. Наиболее частым IP-адресом для роутеров 3Com является: 192.168.1.1 Если этот IP-адрес не работает, используйте список IP-адресов по умолчанию для 3Com, чтобы отыскать его для вашей конкретной модели.
3. Введите имя пользователя и пароль для вашего роутера 3Com
В поле имя пользователя и пароль введите текущее имя пользователя и пароль, а затем нажмите клавишу ввода / вход.
Стандартные учетные данные для входа в 3Com
Готово! Теперь вы сможете выполнить все требуемые настройки устройства.
Как настроить роутер 3Com
После входа в интерфейс администратора 3Com вы сможете изменить все имеющиеся настройки.
Чтобы не нарушить работу сети, при настройке роутера следует действовать осторожно.
Что делать, если после изменения конфигурации мой роутер 3Com или сеть перестает работать
Если вы по ошибке внесете какие-либо изменения, которые повредят вашей домашней сети 3Com, вы всегда можете откатиться назад, воспользовавшись универсальным способом аппаратного сброса 30 30 30.
Как правило, это крайняя мера, и если у вас все еще есть доступ к интерфейсу 3Com, вы всегда можете выполнить вход и сначала попытаться восстановить настройки (конечно же, это предполагает, что вы записали исходные значения перед их изменением).
Настройка офисных роутеров 3COM
Компания 3COM, выпускающая сетевое оборудование, в 2010-м году была выкуплена более крупным производителем «железа» под названием Hewlett Packard. Тем не менее, на просторах нашей страны – и сейчас встречается изготовленный фирмой 3COM роутер под названием «Office Connect 11g router».
Более точно название модели звучит, как 3CRWER100-75. Это сетевое устройство – снабжено микросхемой Wi-Fi на 54 Мбит/с. Еще, существует версия 3CRWER200-75, с «удвоенной» относительно младшей модели скоростью Wi-Fi. Как выполнить настройку – рассмотрим подробнее.
Действия, выполняемые до настройки
Аппаратные подключения
Прежде всего, необходимо подключить роутер к компьютеру (с которого будет происходить настройка). Для этого, любой порт LAN – соединяют с разъемом сетевой карты ПК, используя патч корд. А саму сетевую карту – настраивают на «авто» IP и DNS:
Открываем web-интерфейс
Дождемся, когда компьютер полностью загрузится. После чего, откроем браузер, и перейдем к следующему адресу: 192.168.1.1. Должен появиться запрос авторизации:
Важно знать: если указанный IPадрес длительное время «не отвечает», рекомендуем выполнить сброс настроек роутера. Который, здесь осуществляется не совсем стандартно.
Рассмотрим, как вернуть настройкам роутера их значения «по умолчанию». То есть, как выполнить аппаратный сброс.
Последовательность действий – такая:
- Отключить питание роутера и внешние сетевые устройства.
- Патч-кордом – соединить порт LAN с разъемом «Cable/DSL» (не важно, какой из 4-х портов LAN будет использоваться).
- Затем, включив питание, надо ждать 30 секунд (до «более медленного» мигания индикатора «Alert», расположенного на передней панели).
- Питание роутера – надо выключить, устройство будет готово к настройке.
Кнопка reset, как можно понять, в данном случае не используется.
Настройка базовых функций
Интернет-подключение (DHCP)
Выполнив вход в интерфейс, пользователь видит вкладку «Welcome»:
Интернет-подключение (L2TP)
Рассмотрим пример настройки L2TP-подключения с динамическим IP-адресом. Прежде всего, надо выполнить действия, перечисленные в предыдущей главе. Если требуется подмена MAC-адреса, установите требуемое значение.
Затем, роутер настраивают повторно: вместо «Dynamic IP» выбирают «L2TP», устанавливают значения параметров. Например, как на рисунке:
К параметрам L2TP-протокола относятся:
- Адрес либо доменное имя (Domain Name) сервера L2TP
- Имя (логин) абонента
- Пароль
При желании, можно указать адреса DNS (что ускорит работу роутера). Галочка «Get IP by DHCP» должна быть выставлена (IP-адрес у нас – динамический).
В последнюю очередь, надо нажать «Save», и затем – «Apply». Успешной настройки!
Настраиваем Wi-Fi-сеть
В принципе, перейдя к вкладке «Wireless Settings», становится ясно – доступен необходимый минимум параметров:

Настройка коммутатора 3Com Switch 4210 series
Здравия всем! Достался мне в наследство коммутатор 3Com Switch 4210 52 port. Потребовалось поменять настройки, а на оставленные доступы, коммутатор не отвечал. Пришлось сбрасывать на настройки по умолчанию. Тут оставлю запись для себя, чтобы потом снова не искать в сети.
Памятка
Консоль
Порт консоли находится спереди, подходит стандартный Cisco консольный кабель. Настройки консоли
- Speed — 19200
- Data bits — 8
- Stop bits — 1
- Flow — None
Логин и пароль по-умолчанию, используемые в коммутаторах данных серий: Admin с пустым паролем
Вход в режим конфигурирования
Режим конкурирования в 3Com называется System View, с помощью команды system-view
Вместо cisco команды show, используем display
Management vlan
В данном коммутаторе management vlan мне удалось настроить только через CLI. Вначале удаляем предыдущий vlan
Создаем новый vlan и переименовываем его
Задаем management vlan и настраиваем ip и маршрут
Дальнейшую настройку коммутатора можно настраивать как через CLI так и через Web, но Web как и на многих коммутаторах немного притормаживает.

Как включить web интерфейс в 3com 3crdsf9pwr
Добрый день уважаемые читатели и подписчики блога и канала, если у вас как и у меня на работе есть коммутаторы второго уровня OSI, 3Com Baseline Switch 2952-SFP Plus, то у вас как и у меня может возникнуть потребность во включении web интерфейса у данного устройства, так как ей управлять становится проще, это вам не Cisco с ее удобным IOS. Ниже рассмотрим как это все реализовать.
3Com Baseline Switch 2952-SFP Plus в конфигурации по умолчанию не имеет конфигурации web-интерфейса. Для того, чтобы включить WEB интерфейс на 3Com Baseline Switch 2952-SFP Plus нужно выполнить следующие простые действия:
подключаемся консольным COM port кабелем.
Скорость бит/с 38400,
Биты данных 8,
Четность None,
Стоповые биты 1,
Управление потоком None
Как включить WEB интерфейс в 3Com Baseline Switch 2952-SFP Plus
- Логинимся юзером admin, пароль по умолчанию пустой.
вводим команду _cmdline-mode on, именно так, с подчёрком вначале . Пароль по умолчанию 512900. - вводим команду system-view
включаем http командой ip http enable - теперь присваиваем нашему дивайсу IP адрес. Для этого заходим в режим редактирования интерфейса VLAN — команда interface vlan-interface 1 Единичка — номер VLAN по умолчанию, в этом VLAN находятся все порты свитча. В конфигурации интерфейса vlan 1 набираем команду установки IP адреса: ip address 192.168.102.1 255.255.255.0
- выходим из всех режимов командой quit
- сохраняемся save
Готово! Вот так вот просто включить WEB интерфейс в 3Com Baseline Switch 2952-SFP Plus.
2 управление через web-интерфейс – Инструкция по эксплуатации QTECH QSW-3500
Коммутатор должен иметь сконфигурированный IPv4/IPv6 адрес.
IP адрес хоста (HTTP клиент) и VLAN интерфейс коммутатора, должны иметь
IPv4/IPv6 адреса в одном сегменте сети.
Если второй пункт не может быть выполнен, HTTP клиент должен быть подключен к
IPv4/IPv6 адресу коммутатора с других устройств, таких, как маршрутизатор.
Как и в управлении, коммутатором через Telnet, как только удается ping/ping6 хоста к
IPv4/IPv6 адресам коммутатора и вводится правильный логин и пароль, возможно
получить доступ к коммутатору через HTTP. Ниже описан способ настройки:
Шаг 1: Настройка IP адресов для коммутатора и запуск функции HTTP сервера.
О настройке IP-адреса коммутатора с помощью внеполосного управления, смотри
главу о настройке Telnet управления.
Чтобы конфигурирование по Web стало возможным, нужно ввести команду ip http
server в глобальном режиме конфигурирования:
Switch(config)#ip http server
Шаг 2: Запуск Web-браузера на хосте.
Необходимо открыть Web-браузер на хосте и ввести IP адрес коммутатора, или
непосредственно запустить HTTP протокол в Windows. К примеру, IP адрес коммутатора
“10.1.128.251”;
Запуск HTTP протокола
При обращении коммутатора с IPv6 адреса рекомендуется использовать браузер
версии 1.5 или позднее. Например, если адрес коммутатора 3ffe:506:1:2::3.
Введите адрес IPv6 коммутатора http:// [3ffe: 506:1:2:: 3], адрес обязательно должен
быть заключен в квадратные скобки.

6. Какие имя пользователя и пароль по умолчанию?
Имя пользователя и пароль по умолчанию: admin и password.
7. Как автоматически без USB настроить контроллер для работы через Интернет?
Автопривязка позволяет начать работу с контроллером через Интернет без предварительной настройки с помощью USB.
| Автопривязка возможна только с заводской конфигурацией. |
Для автопривязки необходимо:
Установить SIM-карту в контроллер и подключить питание. На SIM-карте контроллера должен быть отключен запрос PIN-кода и подключены услуги Интернет и определитель номера.
Со своего телефона сделать звонок на номер SIM-карты контроллера. При звонке на контроллер номер вызывающего будет внесен в первое соединение, после чего контроллер подключится к Интернету на 30 минут. При необходимости можно повторно вывести контроллер в Интернет звонком с ранее привязанного номера.
Зафиксировать IMEI контроллера, отпечатанный на наклейке на нижней части корпуса контроллера. Он потребуется в дальнейшем для входа в CCU Shell через Интернет.
8. Как вывести контроллер в онлайн?
Если контроллер не настроен на постоянное подключение к Интернету, то вывести его в онлайн можно одним из способов:
С помощью телефонного звонка на него с ранее настроенного номера.
С помощью текстового SMS: /pass online !.
9. Как войти в CCU Shell через Интернет?
Если контроллер не настроен на постоянное подключение к Интернету, то необходимо вывести его в онлайн (см. Глава 8).
Запустить браузер и зайти по адресу https://ccu.su. После чего будет предложено ввести имя пользователя и пароль.
В поле Имя пользователя ввести имя пользователя и IMEI в формате: user@IMEI , где user — имя пользователя, заданное в настройках соединения, а IMEI — число из 15 цифр, представляющее номер IMEI вашего контроллера. Например: admin@012345678901234 . В поле Пароль ввести заданный ранее пароль.
Имя пользователя и пароль по умолчанию см. в Глава 6.
| Если к компьютеру имеют доступ посторонние люди, не рекомендуется сохранять имя пользователя и пароль в браузере. |
После завершения работы в CCU Shell необходимо нажать Выйти в правом верхнем углу и закрыть браузер.
10. Что делать, если утеряны имя пользователя или пароль для входа в контроллер?
Доступ к контроллеру можно восстановить следующими способами:
Войти в CCU Shell с помощью бота CCU Robot см. ссылку.
Запросить временный доступ к контроллеру с помощью SMS команды GETPASS. Команда дается без признака начала управляющего сообщения / и без SMS пароля. Команда GETPASS работает только если отправлена с номера телефона, заданного в соединении с административными правами. В ответ приходит SMS-сообщение, содержащее имя пользователя в формате user@IMEI и пароль для входа в контроллер. Время действия полученных реквизитов ограничено десятками минут. Данный способ поддерживается в прошивках версии 02.23 от 23.09.2021 и выше.
