Question Answer
What determines the amount of SDRAM or
DRAM memory required?
The DRAM or SDRAM required by a Cisco 7200 series router to support a
combination of installed port adapter types and a Cisco IOS software subset
image is influenced by such variables as the features in the software you plan
to use and the size of your network.
Where can I find Cisco IOS memory
requirements?
Cisco IOS memory requirements are listed in the Cisco IOS Release Notes.
The SDRAM column provides processor memory information. Flash memory
recommendations are also included. For Cisco IOS Release Notes, see the
documentation page for Cisco IOS Software Configuration.
If you are a registered user on Cisco.com, you can access the Software Advisor
at http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl to get memory
requirements.
