TABLE 39 Syslog buer conguration (continued)
Field Description
entries, the 101st entry causes an overrun. After that, the 201st entry
causes a second overrun.
level The message levels that are enabled. Each letter represents a message
type and is identied by the key (level code) below the value. If you disable
logging of a message level, the code for that level is not listed.
messages logged The total number of messages that have been logged since the software
was loaded.
level code The message levels represented by the one-letter codes.
Static and dynamic buers
The software provides a static buer and a dynamic buer:
• Static - logs power supply failures, fan failures, and temperature warning or shutdown messages
• Dynamic - logs all other message types. In previous releases, power supply messages were displayed in static logs only, with
only the last event logged. Beginning with release 03.8.00, power supply messages are displayed in both static and dynamic
logs.
In the static log, new messages replace older ones, so only the most recent message is displayed. For example, only the most recent
temperature warning message will be present in the log. If multiple temperature warning messages are sent to the log, the latest one
replaces the previous one. The static buer is not congurable.
The message types that appear in the static buer do not appear in the dynamic buer. The dynamic buer contains up to the maximum
number of messages congured for the buer (50 by default), then begins removing the oldest messages (at the bottom of the log) to
make room for new ones.
The static and dynamic buers are both displayed when you enter the show logging command.
device(config)# show logging
...
Static Log Buffer:
Aug 27 12:42:42:A:Power Supply 6, 1st right, failed
Dynamic Log Buffer (50 lines):
Aug 27 12:19:04:I:Interface ethernet3/4, state up
Aug 27 12:19:04:I:Interface ethernet6/3, state up
Aug 27 12:19:04:I:Interface ethernet3/2, state up
Aug 27 12:19:04:I:Interface ethernet6/1, state up
Aug 27 12:19:00:N:Module up in slot 6
Aug 27 12:19:00:N:Module up in slot 3
Aug 27 12:18:43:I:Warm start
When you clear log entries, you can selectively clear the either
buer, or you can clear both. For example, to clear only the dynamic
buer, enter the clear logging command at the Privileged EXEC level.
device# clear logging dynamic-buffer
Syntax: clear logging [ dynamic-buer | static-buer]
Specify the dynamic-buer keyword to clear the dynamic buer, or the static-buer keyword to clear the static buer. If you do not
specify a buer, both buers are cleared.
