log here
■
Use to enable logs destined for a console to be displayed at the current console.
■
By default, the local console automatically receives all log messages if console
is a destination. The exception is the cliCommand log, whose log events do not
appear on the console.
■
By default, Telnet consoles do not receive log messages.
■
Example
host1# log here
■
Use the no version to disable logs destined for a console from being displayed
on this console.
■
See log here.
log severity
■
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 *
