When downloading IOS images from any source, integrity is everything. A corrupted image can cause "Ghost in the Machine" errors in your labs that look like configuration mistakes but are actually software bugs.
EVE-NG utilizes the Dynamips wrapper to run legacy Cisco images:
Before loading the file into GNS3 or EVE-NG, calculate its hash and match it exactly to these factory values: : c3725-adventerprisek9-mz.124-15.T14.bin File Size : Approximately 32.8 MB (34,420,536 bytes) MD5 Hash : d5498877cd9783f9801dbfb880e61f43 Verification Steps on Windows (PowerShell) Open Windows PowerShell. Navigate to the directory containing your downloaded file. Run the following command: powershell c3725adventerprisek9mz12415t14image download verified
Always prioritize Cisco Software Central for official, virus-free binaries. If you have a service contract, you can find it under the 3700 Series Routers section.
