Static and dynamic buffers
The software provides two separate buffers:
•
•
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 buffer is not configurable.
The message types that appear in the static buffer do not appear in the dynamic buffer. The
dynamic buffer contains up to the maximum number of messages configured for the buffer (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 buffers are both displayed when you display the log.
BigIron RX(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 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:
BigIron RX# clear logging dynamic-buffer

Syslog buffer configuration (Continued)
Static – logs power supply failures, fan failures, and temperature warning or shutdown
messages
Dynamic – logs all other message types
Displays...
The number of times the Syslog buffer has been cleared by the clear
logging command. For information about clearing the Syslog buffer, refer
to
"Static and dynamic buffers"
The number of times the dynamic log buffer has filled up and been
cleared to hold new entries. For example, if the buffer is set for 100
entries, the 101st entry causes an overrun. After that, the 201st entry
causes a second overrun.
The message levels that are enabled. Each letter represents a message
type and is identified by the key (level code) below the value. If you
disable logging of a message level, the code for that level is not listed.
The total number of messages that have been logged since the software
was loaded.
The message levels represented by the one-letter codes.
