RP/0/0/CPU0:router(config)# logging console emergencies
RP/0/0/CPU0:router(config)# logging buffered 1000000
RP/0/0/CPU0:router(config)# commit
RP/0/0/CPU0:router(config)# end
RP/0/0/CPU0:router# show logging

Purpose
Copies logging messages to an internal buffer.
• Newer messages overwrite older messages after the
buffer is filled.
• Specifying a severity level causes messages at that
level and numerically lower levels to be logged in an
internal buffer. See
logging severity levels.
The buffer size is from 4096 to 4,294,967,295 bytes.
•
Messages above the set limit are logged to the
console.
Commits the target configuration to the router running
configuration.
Ends the configuration session and returns to EXEC
mode.
Displays the messages that are logged in the buffer.
