Netgear FS728TPv2 - ProSAFE 24 Port 10/100 Smart Switch with 4 Gigabit Ports and 24 PoE Ports 管理者ガイド

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 

.

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 Monitoring 

 Logs tab, and then 

click the FLASH Log link.
