%Jun 7 05:22:03 2003 Quidway IFNET/6/UPDOWN:Line protocol on interface
Ethernet0/2, changed state to UP
When the log information is output to info-center, the first part will be "<Priority>".
For example:
<187>Jun 7 05:22:03 2003 Quidway IFNET/6/UPDOWN:Line protocol on interface
Ethernet0/2, changed state to UP
The description of the components of log information is as follows:
1) Priority
The priority is computed according to following formula: facility*8+severity-1. The
default value for the facility is 23. The range of severity is 1~8, and the severity will be
introduced in separate section.
The value of facility can be set by command info-center loghost, .local1 to local7
corresponding to 16 to 23 respectively, for detailed information, refer to RFC3164 (The
BSD syslog Protocol).
Notice: Priority is only effective when information is send to loghost. There is no
character between priority and timestamp.
2) Timestamp
If the logging information is send to the log host, the default format of timestamp is date,
and it can be changed to boot format or none format through the command:
info-center timestamp log { date | boot | none }
The date format of timestamp is "mm dd hh:mm:ss yyyy".
"mm" is month field, such as: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov,
Dec.
"dd" is day field, if the day is little than 10th, one blank should be added, such as " 7".
"hh:mm:ss" is time field, "hh" is from 00 to 23, "mm" and "ss" are from 00 to 59.
"yyyy" is year field.
If changed to boot format, it represents the milliseconds from system booting. Generally,
the data is so big that we use two 32 bits integers, and separated with a dot '.'.
For example:
<189>0.166970 Quidway IFNET/6/UPDOWN:Line protocol on interface Ethernet0/2,
changed state to UP
It means that 166970ms (0*2^32+166970) has passed from system booting.
If changed to none format, the timestamp field is not present in logging information.
Notice: There is a blank between timestamp and sysname. If the timestamp is none
format, there is a blank between priority and sysname.
3) Sysname
