ExtremeWare XOS 11.1 Concepts Guide

You can use more than one command to configure the severity level of the messages sent to a target.
The most direct way to set the severity level of all the sent messages is to use the following command:
configure log target [console | memory-buffer | nvram | primary-msm | backup-msm |
session | syslog [all | <ipaddress> | <ipPort> {vr <vr_name>} [local0 ... local7]]]
{severity <severity> {only}}
When you specify a severity level, messages of that severity level and greater are sent to the target. If
you want only those messages of the specified severity to be sent to the target, use the keyword
only
.
For example, specifying
severity warning
will send warning, error, and critical messages to the target,
but specifying
severity warning only
sends only warning messages.
You can also use the following command to configure severity levels, which associate a filter with a
target:
configure log target [console | memory-buffer | primary-msm | backup-msm | nvram |
session | syslog [all | <ipaddress> | <ipPort> {vr <vr_name>} [local0 ... local7]]]
filter <filter-name> {severity <severity> {only}}
When you specify a severity level as you associate a filter with a target, you further restrict the
messages reaching that target. The filter may allow only certain categories of messages to pass. Only the
messages that pass the filter and then pass the specified severity level reach the target.
Finally, you can specify the severity levels of messages that reach the target by associating a filter with a
target. The filter can specify exactly which message it will pass. Constructing a filter is described in
“Filtering By Components and Conditions” on page 136 .
Components and Conditions
The event conditions detected by ExtremeWare XOS are organized into components and
subcomponents. To get a listing of the components and subcomponents in your release of ExtremeWare
XOS, use the following command:
show log components {<event component>} {version}
For example, to get a list of the components and subcomponents in your system, use the following
command:
show log components
The partial output produced by the command is similar to the following:
Severity
Component Title Threshold
------------------- ---------------------------------------------- -------------
...
...
STP Spanning-Tree Protocol (STP) Error
InBPDU STP In BPDU subcomponent Warning
OutBPDU STP Out BPDU subcomponent Warning
System STP System subcomponent Error
...
...
The display above lists the components, subcomponents, and the default severity threshold assigned to
each. In EMS, you use A period (.) is used to separate component, subcomponent, and condition names.
