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
