Introduction
This document describes how to enable and disable debug on a Cisco Unified Computing System (UCS).
Prerequisites
Requirements
Cisco recommends that you:
-
Have a working knowledge of Cisco UCS Server Blade software and hardware.
-
Be familiar with the UCS manager GUI.
-
Understand the impact and implications of the different commands described in this document.
-
Be familiar with the UCS components and topology.
Components Used
The information in this document is based on Cisco UCS.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a default configuration. If your network is live, make sure that you understand the potential impact of any command.

A typical Cisco UCS topology looks something like this:
How to Enable and Disable Debug on a Cisco UCS
Complete these steps:
-

-
Connect to "NXOS" mode.
-
Enable term mon in order to pipe debug display to console port.
-
Enable the desired debug option.
-
After the debug is done, disable debug all.
-
Turn off the display to console port.
