Purpose
Enters global configuration mode.
Specifies the line to be configured for synchronous logging
of messages.
• console Specifies configurations that occur through
the switch console port or the Ethernet management
port.
• 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.
• (Optional) level severity-level Specifies 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) 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 after
which new messages are dropped. The range is 0 to
2147483647. The default is 20.
