To display the current log configuration of the targets, use the following command:
show log configuration target {console | memory-buffer | nvram | primary-msm | backup-
msm | session | syslog {<ipaddress> | <ipPort> | vr <vr_name>} [local0 ... local7]}
To configure a target, you use specific commands for severity, filters, and formats. In addition, you can
configure the source IP address for a syslog target. Configuring the source IP address allows the
management station or syslog server to identify from which switch it received the log messages. To
configure the source IP address for a syslog target, use the following command:
configure log target syslog [all | <ipaddress> | <ipPort>] {vr <vr_name>} {local0 ...
local7} from <source-ip-address>
The following sections describe the commands required for configuring filters, formats, and severity.
Severity
Messages are issued with one of the severity levels specified by the standard Berkeley Software
Distribution (BSD) syslog values (RFC 3164)—
critical
,
error
,
warning
,
notice
, and
info
—plus three
severity levels for extended debugging—
debug-summary
,
debug-verbose
, and
debug-data
. Note that
RFC 3164 syslog values
emergency
and
alert
are not needed because
critical
is the most severe
event in the system.
The three severity levels for extended debugging—
debug-summary
,
debug-verbose
, and
debug-data
—
require that debug mode be enabled (which may cause a performance degradation). See “Displaying
Debug Information” on page 143 for more information about debugging.
Table 20: Severity levels assigned by the switch
Level Description
Critical A serious problem has been detected that is compromising the operation of the
system; the system cannot function as expected unless the situation is remedied. The
switch may need to be reset.
Error A problem has been detected that is interfering with the normal operation of the
system; the system is not functioning as expected.
Warning An abnormal condition, not interfering with the normal operation of the system, has
been detected that indicate that the system or the network in general may not be
functioning as expected.
Notice A normal but significant condition has been detected, which signals that the system is
functioning as expected.
Info (Informational) A normal but potentially interesting condition has been detected, which signals that
the system is functioning as expected; this level simply provides potentially detailed
information or confirmation.
Debug-Summary A condition has been detected that may interest a developer seeking the reason
underlying some system behavior.
Debug-Verbose A condition has been detected that may interest a developer analyzing some system
behavior at a more verbose level than provided by the debug summary information.
Debug-Data A condition has been detected that may interest a developer inspecting the data
underlying some system behavior.
