Chapter 13 Configuring System Message Logging
Configuring System Message Logging
DETAILED STEPS
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.
EXAMPLE
In the following example, the logging history 1 command is used to configure the system to save only
level 1 (alert) and level 0 (emergency) messages to the logging history table, and, by extension, to send
only these levels in the SNMP notifications. The configuration is then confirmed using the show logging
history command.
Switch(config)# logging history 1
Switch(config)# snmp-server enable traps syslog
Switch(config)# end
Switch#

Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
logging history level
1
1. Table 13-2 lists 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.
Change the default level of syslog messages stored in the history
file and sent to the SNMP server.
See Table 13-2 on page 13-10 for 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.
