Configuring Logging and Logging Correlation
DETAILED STEPS
Examples
Command or Action Purpose
Step 1
configure
Example:
RP/0/RP0/CPU0:router# configure
Enters global configuration mode.
Step 2
logging { ip-address | hostname }
Example:
RP/0/RP0/CPU0:router(config)# logging 10.1.1.1
Specifies a syslog server host to use for system logging.
Step 3
logging trap severity
Example:
RP/0/RP0/CPU0:router(config)# logging trap debugging
Limits the logging of messages sent to syslog servers to
only those messages at the specified level.
• See Table 5-2 for a summary of the logging severity
levels.
Step 4
logging console [ severity ]
Example:
RP/0/RP0/CPU0:router(config)# logging console
emergencies
Logs messages on the console.
• When a severity level is specified, only messages at
that severity level are logged on the console.
• See Table 5-2 for a summary of the logging severity
levels.
Step 5
logging buffered [ severity | buffer-size ]
Example:
RP/0/RP0/CPU0:router(config)# logging buffered
1000000
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 Table 5-2 for a summary of the
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.
Step 6
commit
Example:
RP/0/RP0/CPU0:router(config)# commit
Commits the target configuration to the router running
configuration.
Step 7
end
Example:
RP/0/RP0/CPU0:router(config)# end
Ends the configuration session and returns to EXEC
mode.
Step 8
show logging
Example:
RP/0/RP0/CPU0:router# show logging
Displays the messages that are logged in the buffer.
