Changing the Severity Level of a Syslog Message
To change the severity level of a syslog message, enter the following command:

hostname(config)# logging timestamp
Example:
hostname(config)# logging timestamp

time that they were generated. To remove the date and time
from syslog messages, enter the no logging timestamp
command.
Command Purpose

Prevents the ASA from generating a particular syslog
message. To reenable a disabled syslog message, enter the
logging message message_number command (for example,
logging message 113019). To reenable logging of all disabled
syslog messages, enter the clear config logging disabled
command.
Command Purpose
logging message message_ID level severity_level
Example:
hostname(config)# logging message 113019 level 5
Specifies the severity level of a syslog message. To reset the
severity level of a syslog message to its setting, enter the no
logging message message_ID level current_severity_level
command (for example, no logging message 113019 level 5).
To reset the severity level of all modified syslog messages to
their settings, enter the clear configure logging level
command.
