enter a command excluding certain categories and then follow it with a command
including others.
You can issue successive include commands or successive exclude commands; in
this case, the successive commands expand the list of included or excluded
categories.
Example 1—The first command causes only the osfpGeneral, mplsGeneral, and os
event categories to be logged to system log at 10.10.9.5. The second command reverses
this inclusion and restores the logging of all event categories.
host1(config)#log destination syslog 10.10.9.5 include ospfGeneral
mplsGeneral os
host1(config)#no log destination syslog 10.10.9.5
Example 2—The first command again causes only the osfpGeneral, mplsGeneral, and
os event categories to be logged to system log at 10.10.9.5. The second command
reverses the inclusion of ospfGeneral and os. The mplsGeneral category is still included
and is thus the only category logged.
host1(config)#log destination syslog 10.10.9.5 include ospfGeneral mplsGeneral os
host1(config)#no log destination syslog 10.10.9.5 include ospfGeneral os
Example 3—The first command causes the isisGeneral, ipRoutePolicy, and ipTraffic
event categories to be excluded from logging to system log at 10.1.2.3. The second
command reverses this exclusion and restores the logging of all event categories.
host1(config)#log destination syslog 10.1.2.3 exclude isisGeneral ipRoutePolicy ipTraffic
host1(config)#no log destination syslog 10.1.2.3 exclude
Example 4—The first command again causes the isisGeneral, ipRoutePolicy, and
ipTraffic event categories to be excluded from logging to system log at 10.1.2.3. The
second command reverses the exclusion of ipRoutePolicy and ipTraffic. The isisGeneral
category is still excluded; all other events are logged.
host1(config)#log destination syslog 10.1.2.3 exclude isisGeneral
ipRoutePolicy ipTraffic
host1(config)#no log destination syslog 10.1.2.3 exclude isisGeneral
Example 5—The first command causes the isisGeneral event category to be excluded
from logging to system log at 10.1.2.3. The second command causes ospfGeneral to
also be excluded from logging.
host1(config)#log destination syslog 10.1.2.3 exclude isisGeneral
host1(config)#log destination syslog 10.1.2.3 exclude ospfGeneral
Example 6—The first command causes the isisGeneral event category to be excluded
from logging to system log at 10.1.2.3; all other events are logged. The second command
overrides the first and causes the exclusion of all events except ospfGeneral.
host1(config)#log destination syslog 10.1.2.3 exclude isisGeneral
host1(config)#log destination syslog 10.1.2.3 include ospfGeneral
Use the no version to reverse the effects of previous commands or restore the default,
which is to log all event categories.
