Log files
The log file captures hardware and software log messages, and alarm messages. The switch logs to

The system saves internal log messages in a circular list in memory, which overwrite older log
messages as the log fills. Unlike the log messages in a log file, the internal log messages in memory
do not contain encrypted information, which can limit the information available during
troubleshooting. Free up the disk space on the flash if the system generates the disk space 75% full
alarm. After the disk space utilization returns below 75%, the system clears the alarm, and then
starts logging to a file again.

characters after the log file prefix contain the last three bytes of the chassis base MAC
address. The next two characters are 01. The last three characters (sss) denote the sequence
number of the log file.
• The sequence number of the log file is incremented for each new log file created after the
existing log file reaches the maximum configured size.
• At initial system start up when no log file exists, a new log file with the sequence number 000 is
created. After a restart, the system finds the newest log file from internal flash based on file
timestamps. If the newest log file is on the flash that is used for logging, the system continues
to use the newest log file. And once the maximum configured size is reached, system
