Debug/Syslog Operation
As shown at the top of Figure C-10, if you enter the show debug command when
no Syslog server IP address is configured, the configuration settings for Syslog
server facility, Event Log severity level and system module are not displayed.
However, after you configure a Syslog server address and enable Syslog
logging, all debug and logging settings are displayed with the show debug
command. If you do not want Event Log messages sent to Syslog servers, you
can block the messages from being sent by entering the no debug event
command. (There is no effect on the normal logging of messages in the
switch’s Event Log.)
Debug Command
At the manager level, use the debug command to perform two main functions:
■ Specifies the types of event messages to be sent to an external destination.
■ Specifies the destinations to which selected message types are sent.
By default, no debug destination is enabled and only Event Log messages are
enabled to be sent.
Note To configure a Syslog server, use the logging <syslog-ip-addr> command. For
more information, see “Configuring a Syslog Server” on page C-41.
Debug Messages
Use the debug command to configure the types of debug messages that the
switch can send to configured debug destinations.
Syntax: [no] debug < debug-type >
all
Configures the switch to send all debug message types
(Event Log and LLDP) to configured debug destination(s).
(Default: Disabled - No debug messages are sent.)
