Cisco Systems VPN 3002 manual Event Severity Level, Category, Description

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 9-2describes the severity levels.

Table 9-2 Event Severity Levels

Level	Category	Description
1	Fault	A crash or non-recoverable error.
2	Warning	A pending crash or severe problem that requires user intervention.
3	Warning	A potentially serious problem that may require user action.
4	Information	An information-only event with few details.
5	Information	An information-only event with moderate detail.
6	Information	An information-only event with greatest detail.
7	Debug	Least amount of debugging detail.
8	Debug	Moderate amount of debugging detail.
9	Debug	Greatest amount of debugging detail.
10	Packet Decode	High-level packet header decoding.
11	Packet Decode	Low-level packet header decoding.
12	Packet Decode	Hex dump of header.
13	Packet Decode	Hex dump of packet.

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.
