Configuring and Managing Syslog Messages
To see the severity level of a specific message, enter the following command:
hostname(config)# show logging message message_ID
To see a list of syslog messages with modified severity levels, enter the following command:
hostname(config)# show logging message
To reset the severity level of all modified syslog messages back to their defaults, enter the following
command:
hostname(config)# clear configure logging level
The series of commands in the following example illustrate the use of the logging message command to
control both whether a syslog message is enabled and the severity level of the syslog message:
hostname(config)# show logging message 403503
syslog 403503: default-level errors (enabled)
hostname(config)# logging message 403503 level 1
hostname(config)# show logging message 403503
syslog 403503: default-level errors, current-level alerts (enabled)
hostname(config)# no logging message 403503
hostname(config)# show logging message 403503
syslog 403503: default-level errors, current-level alerts (disabled)
hostname(config)# logging message 403503
hostname(config)# show logging message 403503
syslog 403503: default-level errors, current-level alerts (enabled)
hostname(config)# no logging message 403503 level 3
hostname(config)# show logging message 403503
syslog 403503: default-level errors (enabled)
Changing the Amount of Internal Flash Memory Available for Syslog Messages
You can have the FWSM save the contents of the log buffer to internal flash memory in two ways:
•
•
By default, the FWSM can use up to 1 MB of internal flash memory for log data. The default minimum
amount of internal flash memory that must be free for the FWSM to save log data is 3 MB.
If a log file being saved to internal flash memory would cause the amount of free internal flash memory
to fall below the configured minimum limit, the FWSM deletes the oldest log files to ensure that the
minimum amount of memory remains free after saving the new log file. If there are no files to delete or
if, after all old files are deleted, free memory would still be below the limit, the FWSM fails to save the
new log file.
To modify the settings for the amount of internal flash memory available for syslog messages, perform
the following steps:
Step 1
To specify the maximum amount of internal flash memory available for saving log files, enter the
following command:

Configure logging so that the contents of the log buffer are saved to internal flash memory each time
the buffer wraps
Enter a command instructing the FWSM to save the current contents of the log buffer to internal
flash memory immediately
