Cisco Cisco IOS Software Release 12.2(25)S

To enable XML-formatted system event message logging to be sent trough the CNS event bus, use the 
logging cns-events command in global configuration mode. To disable the ability to send system logging 
event messages through the CNS event bus, use the no form of this command.

logging cns-events [severity-level]

Level 7: debugging

Global configuration

Before you configure this command you must enable the CNS event agent with the cns event command 
because the CNS event agent sends out the CNS event logging messages. The generation of many CNS 
event logging messages can negatively impact the publishing time of standard CNS event messages that 
must be sent to the network.

If the debug cns event command is active when the logging cns-events command is configured, the 
logging of CNS events is disabled. 

severity-level 

The number or name of the desired severity level at which messages should 
be logged. Messages at or numerically lower than the specified level are 
logged. Severity levels are as follows (enter the number or the keyword):

{0 | emergencies}— System is unusable 

{1 | alerts}—Immediate action needed 

{2 | critical}—Critical conditions

{3 | errors}—Error conditions

{4 | warnings}—Warning conditions

{5 | notifications}—Normal but significant conditions

{6 | informational}—Informational messages

{7 | debugging}— Debugging messages
