Using the Error Message Decoder to Search for System
Messages
The Error Message Decoder (EMD) is a tool that will help you to research and resolve error messages
for Cisco software. EMD helps you to understand the meaning of the error messages that display on the
console of Cisco routers, switches, and firewalls.
To use the EMD, copy the message that appears on the console or in the system log, paste it into the
window, and press the Submit button. You will automatically receive an Explanation, Recommended
Action, and, if available, any related documentation for that message.
The EMD is located here:
