Configuring Logging and Logging Correlation
DETAILED STEPS
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 5-4 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 5-4 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 5-4 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.
