Information
Enable system message logging to a local buffer.
Rationale:
The device can copy and store log messages to an internal memory buffer. The buffered data is available only from a router exec or enabled exec session. This form of logging is useful for debugging and monitoring when logged in to a router.
Solution
Configure buffered logging (with minimum size). Recommended size is 64000.
hostname(config)#logging buffered [log_buffer_size]
Impact:
Data forensics is effective for managing technology risks and an organization can enforce such policies by enabling the 'logging buffered' command.
Default Value:
No logging buffer is set by default
