The static and dynamic buffers are both displayed when you display the log.
HP9300(config)# show logging
Syslog logging: enabled (0 messages dropped, 0 flushes, 0 overruns)
Buffer logging: level ACDMEINW, 3 messages logged
level code: A=alert C=critical D=debugging M=emergency E=error
I=informational N=notification W=warning
Static Log Buffer:
Dec 15 19:04:14:A:Fan 1, fan on right connector, failed
Dec 15 19:00:14:A:Fan 2, fan on left connector, failed
Dynamic Log Buffer (50 entries):
Dec 15 18:46:17:I:Interface ethernet 1/4, state up
Dec 15 18:45:21:I:Bridge topology change, vlan 4095, interface 4, changed
state to forwarding
Dec 15 18:45:15:I:Warm start
Notice that the static buffer contains two separate messages for fan failures. Each message of each type has its
own buffer. Thus, if you replace fan 1 but for some reason that fan also fails, the software replaces the first
message about the failure of fan 1 with the newer message. The software does not overwrite the message for
fan 2, unless the software sends a newer message for fan 2.
When you clear log entries, you can selectively clear the static or dynamic buffer, or you can clear both. For
example, to clear only the dynamic buffer, enter the following command at the Privileged EXEC level:
HP9300# clear logging dynamic-buffer
Syntax: clear logging [dynamic-buffer | static-buffer]
You can specify dynamic-buffer to clear the dynamic buffer or static-buffer to clear the static buffer. If you do not
specify a buffer, both buffers are cleared.
Time Stamps
The contents of the time stamp differ depending on whether you have set the time and date on the onboard
system clock.
• If you have set the time and date on the onboard system clock, the date and time are shown in the following
format:
mm dd hh : mm : ss
where:
• mm – abbreviation for the name of the month
dd – day
•
• hh – hours
• mm – minutes
ss – seconds
•
For example, "Oct 15 17:38:03" means October 15 at 5:38 PM and 3 seconds.
• If you have not set the time and date on the onboard system clock, the time stamp shows the amount of time
that has passed since the device was booted, in the following format:
<num> d <num> h <num> m <num> s
where:
