Core Issue

Whenever you install a new card, module or Cisco IOS  Software image, it is important to verify that the router has enough memory and that the hardware and software are compatible with the features that you want to use.


To check for hardware and software compatibility and memory requirements, perform these steps:

  1. To choose software for your network device, refer to Software Advisor.

    Perform these steps:

    1. Verify whether the modules and cards installed on the router are supported by the Cisco IOS Software release that you want to use.
    2. To determine the Cisco IOS Software image that you need by choosing the types of features you want to implement, refer to the Compare the features in different software releases section of Software Advisor.
  2. To check the minimum amount of memory (RAM and Flash) required by the Cisco IOS Software or to download the Cisco IOS Software image, refer to the Cisco IOS Upgrade Planner.

    To determine the amount of memory (RAM and Flash) installed on your router, refer to the Memory Requirements section of How to Choose a Cisco IOS Software Release.

    Choose from one of these options:

    • If you want to keep the same features as the version currently running on your router, but do not know which feature set you are using, issue the show version command on your router and paste it in the Output Interpreter tool. It is important to check for feature support, especially if you plan to use recent software features.
    • If you need to upgrade the Cisco IOS Software image to a new version or feature set, refer to How to Choose a Cisco IOS Software Release.
  3. If a Cisco IOS Software Release upgrade is required, refer to these documents:
