Use to set the severity level for systemwide logs (that is, when you do not specify an
individual event category) or for a specific event category. For a list of severity values,
see Table 3 on page 4.
NOTE: Assigning a log severity to an individual event category changes its
state to Assigned. You cannot change the severity of that event category
using systemwide level commands until you return the event category to
its default, unassigned state with the no log severity command.
If you do not specify a category, the severity value changes for all categories except
individual categories for which you previously set a specific severity level. See
"Configuring Log Severity for Individual and Systemwide Logs" on page 10 for details.
Each event category has its own default severity value. For most categories, the default
is Error.
To disable all default level log messages, use the off keyword without specifying an
event category.
To disable individual level log messages, use the off keyword and specify the event
category that you want to disable.
Example
host1(config)#log severity warning
Use the no version to return the systemwide (when assigned) or default severity values
to event categories.
Use the no version with an* (asterisk) to return all event categories (modified either
systemwide or individually) to their default severity setting. For example:
host1(config)#no log severity *
See log severity.
Use to remove the limit on the number of outstanding buffers for an event category,
such as when the system is dropping logs of a particular category.
Example
host1(config)#log unlimit qos
Use the no version to return to the default value.
See log unlimit.
Use to set the verbosity level for a selected category or for all categories.
If you do not specify a category, then the verbosity level is set for all categories.
The default verbosity setting for all logs is low.
Example
host1(config)#log verbosity low
