Почему не пингуется шлюз cisco vlan?
Здравствуйте. Вроде простой вопрос, но не могу разобраться, что не так.
На циске создаю влан 511, назначаю его на порт gi1/0/11, к этому порту подключаю компьютер (шлюзом указываю влан). Но пинги не идут. с PC1 не пингуется шлюз, а с SW1 не пингуется компьютер.
SW1

PC1
Адрес: 85.86.87.90
Маска: 255.255.255.248
Шлюз: 85.86.87.94
Куда смотреть, всю голову уже сломал.
Дополнительно:
Это в эмуляторе или оборудование реальное?
show vlan id 511 show mac address-table interface gi1/0/11 show interfaces gi1/0/11 show arp |
show vlan id 511 show mac address-table interface gi1/0/11 show interfaces gi1/0/11 show arp
И еще, вы явно создавали влан 511? Командами наподобие приведенных ниже? Без явного создания влана он не будет работать, по крайней мере на старых каталистах 29XX, 37XX это так.

Ответить на вопрос
Для того чтобы понять, почему шлюз Cisco VLAN не пингуется, следует выполнить несколько шагов для диагностики и решения проблемы.
1. Проверьте конфигурацию VLAN на устройстве Cisco. Убедитесь, что VLAN правильно настроен и активен. Проверьте, что шлюз VLAN настроен правильно, включая IP-адрес, подсеть и шлюз по умолчанию.
2. Проверьте, что интерфейс VLAN активен и поднят. Иногда проблема может быть связана с тем, что интерфейс VLAN выключен или находится в состоянии ошибки.
3. Проверьте настройки маршрутизации на устройстве Cisco. Убедитесь, что маршрут к сети, к которой принадлежит шлюз VLAN, настроен правильно.
4. Проверьте настройки брандмауэра на устройстве Cisco. Возможно, брандмауэр блокирует ICMP-пакеты, которые используются для пинга.
5. Проверьте настройки сетевой инфраструктуры. Убедитесь, что сетевые коммутаторы и другие устройства правильно настроены для передачи трафика к шлюзу VLAN.
Если после выполнения всех этих шагов проблема не решена, рекомендуется обратиться к специалисту по сетевым технологиям для более детального анализа и решения проблемы.
