Collecting log and operating information
IMPORTANT:
To facilitate quick troubleshooting, execute the following commands:
•
info-center enable —Enables the information center. By default, the information center is enabled.
•
info-center logfile enable —Enables the log file feature so the system outputs logs to log files. By default,
the log file feature is enabled.
•
info-center diagnostic-logfile enable —Enables saving diagnostic logs to the diagnostic log file. By
default, saving diagnostic logs to the diagnostic log file is enabled.
During operation, the device generates common log messages and diagnostic log messages to
record information about routine operations and operating status. Table 1 shows the types of files
that the system uses to store the log messages. You can export these files by using FTP, TFTP, or
USB.
In an IRF system, log files are stored on the master device. Multiple devices will have log files if
master/subordinate switchovers have occurred. You must collect log files from all member devices.
To more easily identify log files from different member devices, use two directories to save the log
files from each member device and include member IDs in the directory names.
