Configure Alarm
Configures statistical alarm thresholds for a line. The configurable items for SONET and PLCP are
defined in RFC 2258. The configurable items for DS3 and E3 are defined in RFC 2496. The items that
constitute a configuration are:
•
Line type: SONET, DS3, E3, or PLCP
•
Tested layer: section, line, or path (for example, SONET line)
•
Test periods of 15 minutes and 24 hours
•
Degrees of error-time: errored seconds and severely errored seconds
•
Types of errors, including framing errors, code violations, and unavailable
•
Severity of alarm triggered when a threshold is crossed: minor or major
A keyword identifies the alarm criteria. Each keyword identifies the tested layer (line, and so on), the
type of threshold (errored seconds, and so on), and the test period of 15 minutes or 24 hours. For
example, -lnes15 indicates the number of errored seconds on the line layer during any 15 minute period.
See the Syntax Description for a list and definitions of all keywords.
