System Message Overview
This guide describes the Cisco ME 3400E, ME 3400, and ME 2400 Ethernet Access switches system
messages. During operation, the system software sends these messages to the console (and, optionally,
to a logging server on another system). Not all system messages indicate problems with your system.
Some messages are purely informational, whereas others can help diagnose problems with
communications lines, internal hardware, or the system software. This guide also includes error
messages that appear when the system fails.
Note
For information about system messages that are not Cisco ME switch platform-specific, see the Cisco
IOS Software System Messages for Cisco IOS Release 12.2S.

How to Read System Messages
System log messages can contain up to 80 characters and a percent sign (%), which follows the optional
sequence number or time stamp information, if configured. Messages are displayed in this format:
seq no:timestamp: %facility-severity-MNEMONIC:description
By default, a switch sends the output from system messages to a logging process.
Each system message begins with a percent sign (%) and is structured as follows:
%FACILITY-SEVERITY-MNEMONIC: Message-text

FACILITY is a code consisting of two or more uppercase letters that show the facility to which the
message refers. A facility can be a hardware device, a protocol, or a module of the system software.
Examples of facilities are: ACLMGR, DOT1X, and HARDWARE.
The messages are described in
order by facility code with the most severe (lowest number) errors described first.
SEVERITY is a single-digit code from 0 to 7 that reflects the severity of the condition. The lower
the number, the more serious the situation.
