IP Connection Blog: Простой генератор конфигураций для коммутаторов

В месте где я сейчас работаю конфигурированием занимаются несколько человек.
При этом установку на сеть контролируют не всегда те же люди что и конфигурируют.
Поэтому чтобы все были в курсе о новых настроенных коммутаторах был сделан небольшой автоконфигуратор. Ну на самом деле просто генератор конфигурации.

Возможности скрипта :

Автоматическая подстановка необходимых значений
Складирование готовых конфигураций
Отправка письма с вложенной конфигурацией

В целом получилась такая конструкция из нескольких файлов :
Для простоты показываю как сделать для 2х моделей коммутаторов: Dlink DES 3200 и SNR 2965.
Внимание в конфигурации используются вымышленные пароли и IP адреса
В папку складываем файлы :
