Cisco WAN SONET MIB File

The Cisco WAN SONET MIB objects are defined in the file CISCO-WAN-SONET-MIB.my. This MIB file describes the SONET/SDH interface objects. These objects are an extension to the standard SONET MIB, described in RFC 2558.

Contents of this chapter include:

SONET Section Alarm Table

The SONET/SDH Section Alarm table contains objects for setting alarm thresholds and reading alarm severity.

The object identifiers are listed in Table 6-1.

Sequence of cwsSectionAlarmEntry

Contains the objects for setting alarm thresholds and reading alarm severity.

Max-Access: not-accessible

Status: current

none

cwsSectionAlarm
Entry

cwsSectionAlarmEntry

Provides an entry in the alarm table. The entries exist for active SONET lines, with default threshold values. Thresholds may be configured for errored seconds (ES), Severely Errored Seconds (SES), Severely Errored Framing Seconds (SEFS) and Coding Violations (CV) for section layer SONET lines. Once these thresholds are exceeded, a minor or major alarm is raised.

Refer to RFC 2558 for descriptions of ES, SES, SEFS, and CV.

Max-Access: not-accessible

Status: current

The index is ifIndex.

none

cwsSectionStatisticalAlarmSeverity

Max-Access: read-write

Status: current

25

cwsSectionStatAlarmStatus

Unsigned32 (1..511)

Indicates the status of the interface. When an alarm is raised, this would indicate which threshold was exceeded. This object is updated every 15 minutes. Once the current 15-minute window has passed, and there are no errors in the current 15-minute window, the object is cleared from the lower level SONET task. The cwsSectionStatAlarmStatus is a bit map represented as a sum, therefore, it can represent multiple defects simultaneously. If none of the bits are set, it indicates no defect.
