| 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 |
|

|
|
|
| causes a second overrun. |

| The message levels that are enabled. Each letter represents a message |

Static and dynamic buffers
The software provides two separate buffers:
•Static – Logs power supply failures, fan failures, and temperature warning or shutdown messages.
•Dynamic – Logs all other message types.
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

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
Syntax: clear logging [dynamic-buffer static-buffer]
