sonusApsGroupOperStatus

Module: SONUS-SONET-APS-MIB

OID (symbolic): SONUS-SONET-APS-MIB::sonusApsGroupOperStatus

OID (numeric): 1.3.6.1.4.1.2879.2.5.9.1.2.1.12

Node type: OBJECT-TYPE

Type: Bits

Access: read-only

Description: The current status of the APS group.

Bit 0 - Extra Traffic. Indicates that extra traffic is currently being accepted on the protection line.

Bit 1 - Protection Switching Byte Defect. Indicates that either an inconsistent APS byte or an invalid code has been detected.

Bit 2 - Channel Mismatch. Indicates that a mismatch between the transmitted K1 channel and the received K2 channel has been detected.

Bit 3 - APS Mode Mismatch. Indicates a conflict between the current local mode and the received K2 mode information. Modes other than 1+1 unidirectional monitor protection line: K2 bit 5 indicates the architecture; K2 bits 6-8 indicate if the mode is unidirectional or bidirectional.

Bit 4 - Far-End Protection-Line Defect. Indicates the LTE received an SF code for the protection line, which means that the far-end LTE is no longer receiving its request, or (in bidirectional operation) the far-end LTE considers the near-end LTE's request to be invalid.

What is sonusApsGroupOperStatus?

Read-only BITS reporting the current condition of this APS group across five flags (extra traffic active, protection-switching byte defect, channel mismatch, mode mismatch, far-end protection-line defect), giving an admin a compact snapshot of protection-switching health.
