Task Command 1. system-view Change the directory of the security log file. 2. info-center security-logfile directory dir-name Manually save all the contents in the security log file buffer into the security log file. security-logfile save Remarks By default, the security log file is saved in the seclog directory in the root directory of the storage medium. The configuration made by this command cannot survive an IRF reboot or a master/subordinate switchover. Available in any view. Enabling synchronous information output The output of system logs interrupts ongoing configuration operations. You have to find the previously input commands before the logs. Synchronous information output can show the previous input after log output and a command prompt in command editing mode, or a [Y/N] string in interaction mode so you can continue your operation from where you were stopped. To enable synchronous information output: Step 1. Enter system view. 2. Enable synchronous information output. Command system-view info-center synchronous Remarks N/A By default, synchronous information output is disabled. Enabling duplicate log suppression The output of consecutive duplicate logs at an interval of less than 30 seconds wastes system and network resources, making it difficult for network administrators to find useful information and maintain the device. With this feature enabled, the system starts a suppression period upon outputting a log: • During the suppression period, the system does not output logs that have the same module name, level, mnemonic, location, and text as the previous log. • After the suppression period expires, if the same log continues to appear, the system outputs the suppressed logs and the log number and starts another suppression period. The suppression period is 30 seconds for the first time, 2 minutes for the second time, and 10 minutes for subsequent times. • If a different log is generated during the suppression period, the system aborts the current suppression period, outputs suppressed logs and the log number and then the different log, and starts another suppression period. To enable duplicate log suppression: Step 1. Enter system view. Command system-view Remarks N/A 61

Enabling duplicate log suppression
The output of consecutive duplicate logs at an interval of less than 30 seconds wastes system and network
resources, making it difficult for network administrators to find useful information and maintain the
device.
With this feature enabled, the system starts a suppression period upon outputting a log:
•
During the suppression period, the system does not output logs that have the same module name,
level, mnemonic, location, and text as the previous log.
•
After the suppression period expires, if the same log continues to appear, the system outputs the
suppressed logs and the log number and starts another suppression period. The suppression period
is 30 seconds for the first time, 2 minutes for the second time, and 10 minutes for subsequent times.
•
If a different log is generated during the suppression period, the system aborts the current
suppression period, outputs suppressed logs and the log number and then the different log, and
starts another suppression period.
