DETAILED STEPS
Purpose Command or Action
Enters global configuration mode.
configure terminal
Example:
Switch# configure terminal
Step 1
Specifies the line to be configured for synchronous logging of messages. line [ console | vty ] line-number
[ ending-line-number ]
Step 2
•
console
—
Specifies configurations that occur through the switch console
port or the Ethernet management port.
Example:
Switch(config)# line console
•
line vty line-number
— Specifies 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
You can also 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.
Enables synchronous logging of messages. logging synchronous [ level
[ severity-level | all ] | limit
number-of-buffers ]
Step 3
• (Optional) level severity-level — Specifies the message severity level.
Messages with a severity level equal to or higher than this value are printed
Example:
Switch(config)# logging
asynchronously. Low numbers mean greater severity and high numbers mean
lesser severity. The default is 2.
• (Optional)
level all
— Specifies that all messages are printed asynchronously
regardless of the severity level.
synchronous level 3 limit 1000
•
(Optional) limit number-of-buffers
—
Specifies 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.
