System Messages; Syslog Server Implementation - Cisco Nexus 9000 Series Troubleshooting Manual

System Messages

System Messages
The system software sends syslog (system) messages to the console (and, optionally, to a logging server on
another device). Not all messages indicate a problem with your device. Some messages are purely informational,
while others might help diagnose problems with links, internal hardware, or the device software.
System 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.
Each system message is followed by an explanation and recommended action. The action may be as simple
as "No action is required." It might 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 DCNM 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 device to send a copy of the message log to a host for more permanent storage.
This feature allows you to examine the logs over a long period of time or if the device is not accessible.
This example shows how to configure the device to use the syslog facility on a Solaris platform. Although a
Solaris host is being used, the syslog configuration on all UNIX and Linux systems is very similar.
Syslog uses the facility to determine how to handle a message on the syslog server (the Solaris system in this
example) and the message severity. Different message severities are handled differently by the syslog server.
They could be logged to different files or e-mailed to a particular user. Specifying a severity level on the
syslog server determines that all messages of that level and greater severity (lower number) will be acted upon
as you configure the syslog server.
