Chapter 70 Configuring System Message Logging
Configuring System Message Logging
To disable synchronization of unsolicited messages and debug output, use the
no logging synchronous [ level severity-level | all ] [ limit number-of-buffers ] line configuration
command.
Enabling and Disabling Timestamps on Log Messages
Note
By default, log messages are not time-stamped.
To enable time-stamping of log messages, perform this task:
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config)# line
[
console
|
vty
]
line-number
[
ending-line-number
]
Specifies the line to be configured for synchronous logging of
messages.
•
Use the console keyword for configurations that occur using the
switch console port.
• Use the line vty line-number command to specify which vty
lines are to have synchronous logging enabled. You use a vty
connection for configurations that occur through a Telnet
session. The range of line numbers is from 0 to 15.
You can change the setting of all 16 vty lines at once by entering:
line vty 0 15
Or you can change the setting of the single vty line being used for
your current connection. For example, to change the setting for vty
line 2, enter:
line vty 2
When you enter this command, the mode changes to line
configuration.
Step 3
Switch(config)# logging synchronous
[
level
[
severity-level
|
all
] |
limit
number-of-buffers
]
Enables synchronous logging of messages.
•
(Optional) For level severity-level , specify the message severity
level. Messages with a severity level equal to or higher than this
value are printed asynchronously. Low numbers mean greater
severity and high numbers mean lesser severity. The default is 2.
•
(Optional) Specifying level all means that all messages are
printed asynchronously regardless of the severity level.
•
(Optional) For limit number-of-buffers , specify the number of
buffers to be queued for the terminal after which new messages
are dropped. The range is 0 to 2147483647. The default is 20.
Step 4
Switch(config)# end
Returns to privileged EXEC mode.
Step 5
Switch# show running-config
Verifies your entries.
Step 6
Switch#
copy running-config
startup-config
(Optional) Saves your entries in the configuration file.
