Chapter 1 Troubleshooting Overview
System Messages
System Messages
The system software sends these syslog (system) messages to the console (and, optionally, to a logging
server on another system) during operation. Not all messages indicate a problem with your system. Some
messages are purely informational, while others might help diagnose problems with links, internal
hardware, or the system software.
This section contains the following topics:
• System Message Text, page 1-10
• Syslog Server Implementation, page 1-10
• Implementing Syslog with Fabric Manager, page 1-11
• Implementing Syslog with the CLI, page 1-12
System Message Text
Message-text is a text string that describes the condition. This portion of the message might contain
detailed information about the event, including terminal port numbers, network addresses, or addresses
that correspond to locations in the system memory address space. Because the information in these
variable fields changes from message to message, it is represented here by short strings enclosed in
square brackets ([ ]). A decimal number, for example, is represented as [dec].
PORT-3-IF_UNSUPPORTED_TRANSCEIVER: Transceiver for interface [chars] is not supported.
Use this string to find the matching system message in the Cisco MDS 9000 Family System Messages
Reference.
Each system message is followed by an explanation and recommended action. The action may be as
simple as “No action required.” It may involve a fix or a recommendation to contact technical support
as shown in the following example:
Error Message PORT-3-IF_UNSUPPORTED_TRANSCEIVER: Transceiver for interface [chars]
is not supported.
Explanation
Transceiver (SFP) is not from an authorized vendor.
Recommended Action Enter the show interface transceiver CLI command or similar Fabric
Manager/Device Manager command to determine the transceiver being used. Please contact your
customer support representative for a list of authorized transceiver vendors.
Syslog Server Implementation
The syslog facility allows the Cisco MDS 9000 Family platform to send a copy of the message log to a
host for more permanent storage. This can be useful if the logs need to be examined over a long period
of time or when the Cisco MDS switch is not accessible.
This example will demonstrate how to configure a Cisco MDS switch to utilize the syslog facility on a
Solaris platform. Although a Solaris host is being used, syslog configuration on all UNIX and Linux
systems is very similar.
