Configuring and Managing Syslog Messages Chapter 25 Monitoring the Firewall Services Module 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: • 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 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: 25-18 Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide using ASDM OL-20748-01
