PurposeCommand or Action
Enters global configuration mode.configure terminal
Example:
Step 1
Device# configure terminal
Specifies the line to be configured for
synchronous logging of messages.
line [console | vty] line-number
[ending-line-number]
Step 2
Example:
• console —Specifies configurations that
occur through the switch console port or
the Ethernet management port.
Device(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
Example:
a severity level equal to or higher than this
Device(config)# logging synchronous level
value are printed asynchronously. Low
3 limit 1000
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.
• (Optional) limit
number-of-buffers—Specifies the number
of buffers to be queued for the terminal
