Memory Capacities

You might need to upgrade memory for the following reasons:

•

This document describes how to upgrade both dynamic memory and compact flash memory. Cisco 3700

series routers use dynamic memory in the form of SDRAM DIMMs (Cisco 3725 router) or SDRAM

SODIMMs (Cisco 3745 router). Memory capacities are shown in

To upgrade to a new Cisco IOS feature set or release that requires additional memory. (Memory

requirements for each feature set and release are available in the release notes for that release.)

To use very large routing tables, many protocols (as may be required, for example, when the router

is part of both a large external network and your internal network), or other memory-intensive

features such as spoofing or protocol translations.
