Chapter 9 Events
Event Severity Level
Note The Cisco-specific event classes provide information that is meaningful only to Cisco engineering
or support personnel. Also, the DBG and DECODE events require significant system resources and
might seriously degrade performance. We recommend that you avoid logging these events unless
Cisco requests it.
Event Severity Level
Severity level indicates how serious or significant the event is; that is, how likely it is to cause unstable
operation of the VPN 3002, whether it represents a high-level or low-level operation, or whether it
returns little or great detail. Level 1 is most significant. Table 9-2 describes the severity levels.
Table 9-2 Event Severity Levels
Within a severity level category, higher-numbered events provide more details than lower-numbered
events, without necessarily duplicating the lower-level details. For example, within the Information
category, Level 6 provides greater detail than Level 4 but does not necessarily include the same
information as Level 4.
Logging higher-numbered severity levels degrades performance, since more system resources are used
to log and handle these events.
Note The Debug (7–9) and Packet Decode (10–13) severity levels are intended for use by Cisco
engineering and support personnel. We recommend that you avoid logging these events unless Cisco
requests it.
The VPN 3002, by default, displays all events of severity level 1 through 3 on the console. It writes all
events of severity level 1 through 5 to the event log. You can change these defaults on the
Configuration | System | Events | General screen, and you can configure specific events for special
handling on the Configuration | System | Events | Classes screens.
