Chapter 26 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.
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.
