Viewing a debug/syslog configuration
Use the show debug
command
to display the currently configured settings for:
Debug message types and Event Log message filters (severity level and system module) sent to debug destinations
Debug destinations (syslog servers or CLI session) and syslog server facility to be used
Syntax:
show debug
Displays the currently configured debug logging
destinations and message types selected for debugging purposes. (If
no syslog server address is configured with the logging <syslog-ip-addr>
command, no show
debug
command output is displayed.)
Output of the show debug command
switch(config)# show debug Debug Logging Destination: Logging -- 10.28.38.164 Facility=kern Severity=warning System module=all-pass Enabled debug types: event
Example:
In the following Example:, no syslog servers
are configured on the switch (default setting). When you configure
a syslog server, debug logging is enabled to send Event Log messages
to the server. To limit the Event Log messages sent to the syslog
server, specify a set of messages by entering the logging
severity
and logging system-module
commands.
As shown at the top of Syslog configuration to receive event log messages from specified system module and severity levels, 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.)
Example:
The next Example: shows how to configure:
Debug logging of ACL and IP-OSPF packet messages on a syslog server at 18.38.64.164 (with user as the default logging facility).
Display of these messages in the CLI session of your terminal device's management access to the switch.
Blocking Event Log messages from being sent from the switch to the syslog server and a CLI session.
To configure syslog operation in these ways with the debug/syslog feature disabled on the switch, enter the commands shown in Debug/syslog configuration for multiple debug types and multiple destinations.
