Chapter 32 Configuring System Message Logging

Configuring System Message Logging

Beginning in privileged EXEC mode, follow these steps to change the level and history table size defaults. This procedure is optional.

 

Command

Purpose

Step 1

 

 

configure terminal

Enter global configuration mode.

 

 

 

Step 2

logging history level1

Change the default level of syslog messages stored in the history file and

 

 

sent to the SNMP server.

 

 

See Table 32-3 on page 32-10for a list of level keywords.

 

 

By default, warnings, errors, critical, alerts, and emergencies messages

 

 

are sent.

Step 3

 

 

logging history size number

Specify the number of syslog messages that can be stored in the history

 

 

table.

 

 

The default is to store one message. The range is 0 to 500 messages.

Step 4

 

 

end

Return to privileged EXEC mode.

Step 5

 

 

show running-config

Verify your entries.

Step 6

 

 

copy running-config startup-config

(Optional) Save your entries in the configuration file.

 

 

 

1.Table 32-3lists the level keywords and severity level. For SNMP usage, the severity level values increase by 1. For example, emergencies equal 1, not 0, and critical equals 3, not 2.

When the history table is full (it contains the maximum number of message entries specified with the logging history size global configuration command), the oldest message entry is deleted from the table to allow the new message entry to be stored.

To return the logging of syslog messages to the default level, use the no logging history global configuration command. To return the number of messages in the history table to the default value, use the no logging history size global configuration command.

Enabling the Configuration-Change Logger

You can enable a configuration logger to keep track of configuration changes made with the command-line interface (CLI). When you enter the logging enable configuration-change logger configuration command, the log records the session, the user, and the command that was entered to change the configuration. You can configure the size of the configuration log from 1 to 1000 entries (the default is 100). You can clear the log at any time by entering the no logging enable command followed by the logging enable command to disable and re-enable logging.

Use the show archive log config {all number [end-number] user username [session number] number [end-number] statistics} [provisioning] privileged EXEC command to display the complete configuration log or the log for specified parameters.

The default is that configuration logging is disabled.
