1. Table 31-3 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.
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.
