Как определить сколько памяти DRAM на маршрутизаторе

При обновлении IOS это наиважнейший параметр, т.к. в случае если памяти окажется меньше чем требуется маршрутизатор попросту не загрузится.
Для определения мы используем команду show version
Мы должны найти строчку подобную выделенной в примере ниже.
Общая память разделена на два числа, поэтому нам нужно их сложить, в нашем случае получится:
44237K + 4915K = 49152K или 48Mb
