If the address of the log host is specified in the information center of the switch, when logs are
generated, the switch sends the logs to the log host in the above format. For detailed information,
refer to Setting to Output System Information to a Log
There is the syslog proce ss on the Unix or Linux platform, you can start the process to receive the
logs sent from the switch; in the Windows platform, you need to install the specific software, and it
will operate as the syslog host.
Some log host software will resolve the received information as well as its format, so th
format d isplayed on the log host is different from the one described in this manual.
What follows is a detailed explanation of the information fields involved:
Int_16 (Priority)
The priority is calculated using the following formula: facility*8+severity-1, in which
facility (the device name)
local5 is 21, and so on).
severity (the information level) ranges from 1 to 8.
associated with each severity.
No te that the priority field appears only when the information has been sent to the log host.
Times tamp
Timestamp records the time when system information is generated to allow users to check and identify
syst em events.
Note that there is a space between the timestamp and sysname (host name) fields.
The time stamp has the following two formats.
1) Without the universal time coordinated (UTC) time zone, the time stamp
dd hh:mm:ss:ms yy
2) With the UTC time zone, the time stamp is in the format of "Mmm dd hh:mm:ss:ms yyyy [GMT +|-
hh:mm:ss]".
Each field is described as follows:
"Mmm" represents the month, and the available values are: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug,
Sep, Oct, Nov, and Dec.
"dd" is the date, which shall follow a space if less than 10, for example, " 7".
"hh:mm:ss:ms" is the local time, where "hh" is in the 24-hour format, rangin
"mm" and "ss" range from 00 to 59, "ms" ranges from 000 to 999. (Note that: the time stamp of the
system information sent from the information center to the log host is with a precision of sec
while that of the system
logbuffer, trapbuffer and the SNMP is with a precision of milliseconds.)
"yyyy" is the year.
"[GMT +|- hh:mm:ss]" is the UTC time zone, which represents the time difference with the
Green wich standard time.
Because switches in a network may distribute in different time zones, when the time displayed in the
time stamp s of output information is the local time on each switch, it is not so convenient for you to
