FS728TP Smart Switch Software Administration Manual
The following example shows the standard format for a log message:
<14> Mar 24 05:34:05 10.131.12.183-1 UNKN[2176789276]:
main_login.c(179) 3855 %% HTTP Session 19 initiated for user admin
connected from 10.27.64.122
The number contained in the angle brackets represents the message priority, which is
derived from the following values:
Priority = (facility value × 8) + severity level.
The facility value is usually one, which means it is a user-level message. Therefore, to
determine the severity level of the message, subtract eight from the number in the angle
brackets. The example log message has a severity level of 6 (informational). For more
information about the severity of a log message, see the
Severity Filter
description on page
208 .
The message was generated on March 24 at 5:34:05 a.m by the switch with an IP address of
10.131.12.183. The component that generated the message is unknown, but it came from
line 179 of the main_login.c file. This is the 3,855
th
message logged since the switch was last
booted. The message indicates that the administrator logged onto the HTTP management
interface from a host with an IP address of 10.27.64.122.

FLASH Log Configuration
The FLASH log is a log that 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. 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.
Use the FLASH Log Configuration page to enable or disable persistent logging and to set the
severity filter.
To access the FLASH Log Configuration page, click the
