Question

Difficulty: MediumSyslog Operations, Severity Levels, and Log Destination Configuration

A network administrator is documenting Syslog severity level definitions for an enterprise Cisco IOS router deployment. Place the following Syslog severity level names in sequence from the lowest numerical severity code (most critical) to the highest numerical severity code (least critical).

  1. 1Alert
  2. 2Error
  3. 3Notice
  4. 4Informational

Answer

The correct order from lowest numerical code to highest numerical code is Alert (Level 1), Error (Level 3), Notice (Level 5), and Informational (Level 6).
Cisco IOS Syslog severity levels range numerically from 0 to 7, where lower numbers indicate higher severity. The correct sequence from lowest numerical code (most severe) to highest numerical code (least severe) is Alert (level 1), Error (level 3), Notice (level 5), and Informational (level 6).

Step-by-Step Solution

1
Determine the numerical severity code associated with each Syslog severity level name.
Alert is level 1, Error is level 3, Notice is level 5, and Informational is level 6.
Cisco IOS Syslog follows standard severity level mappings from 0 (Emergency) to 7 (Debugging).
2
Sequence the items in ascending order based on their numerical severity values.
Alert (1) -> Error (3) -> Notice (5) -> Informational (6).
Lower numerical severity codes represent higher-priority, more critical events.
