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, ranging
■
from 00 to 23, both "mm" and "ss" range from 00 to 59, "ms" ranges from
000 to 999.
"yyyy" is the year.
■
"[GMT +|- hh:mm:ss]" is the UTC time zone, which represents the time
■
difference with the Greenwich standard time.
Because switches in a network may distribute in different time zones, when the
time displayed in the time stamps of output information is the local time on each
switch, it is not so convenient for you to locate and solve problems globally. In this
case, you can configure the information center to add UTC time zone to the time
stamp of the output information, so that you can know the standard time when
the information center processing each piece of information. That is, you can
know the Greenwich standard time of each switch in the network based on the
UTC record in the time stamp.
To add UTC time zone to the time stamp in the information center output
information, you must:
Set the local time zone
■
Set the time stamp format in the output direction of the information center to
■
date
Configure to add UTC time zone to the output information
■
After the above configuration, the UTC time zone will be displayed in the output
information, like the following:
%Dec 8 10:12:21:708 2006 [GMT+08:00:00] 4210 SHELL/5/LOGIN:- 1 -
VTY(1.1.0.2) in unit1 login
Sysname
Sysname is the system name of the local switch and defaults to "4210".
You can use the sysname command to modify the system name. Refer to "Basic
System Configuration and Debugging" on page 483.
Note that there is a space between the sysname and module fields.
Module
The module field represents the name of the module that generates system
information. You can enter the info-center source ? command in system view to
view the module list. Refer to Table 340 for module name and description.
