The persistent log is stored in persistent storage, which means that the log messages are retained across a switch reboot.
•
The first log type is the
system startup log
. The system startup log stores the first N messages received after system
reboot. This log always has the log full operation attribute set to stop on full and can store up to 32 messages.
•
The second log type is the
system operation log
. The system operation log stores the last N messages received
during system operation. This log always has the log full operation attribute set to overwrite. This log can store up to
1000 messages.
Either the system startup log or the system operation log stores a message received by the log subsystem that meets the
storage criteria, but not both. In other words, on system startup, if the startup log is configured, it stores messages up to its
limit. The operation log, if configured, then begins to store the messages.
The system keeps up to three versions of the persistent logs, named <FILE>1.txt, <FILE>2.txt, and <FILE>3.txt. Upon
system startup, <FILE>3.txt is removed, <FILE>2.txt is renamed <FILE>3.txt, <FILE>1.txt is renamed <FILE>2.txt,
<FILE>1.txt is created and logging begins into <FILE>1.txt. (Replace <FILE> in the above example to specify
olog
for the
operation log and
slog
for the startup log.)
The local persistent logs can be retrieved via the Web or CLI, or via xmodem over the local serial cable.
Use the
Persistent Log Configuration
page to enable or disable persistent logging and to set the severity filter.
To access the
Persistent Log Configuration
page, click
LAN > Administration >
Log > Persistent Logger

in the navigation menu.
