KB.15.15

CAUTION: If you configure a severity-level, system-module, logging destination, or logging facility

value and save the settings to the startup configuration (for example, by entering the write

memory command), the debug settings are saved after a system reboot (power cycle or reboot)

and re-activated on the switch. As a result, after switch startup, one of the following situations may

occur:

• Only a partial set of Event Log messages may be sent to configured debug destinations.

• Messages may be sent to a previously configured syslog server used in an earlier debugging

session.

Viewing a syslog/debug 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.)

Figure 206 Sample output of show debug command

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.
