sonetSectionStatus

Module: Fore-SONET-MIB

OID (symbolic): Fore-SONET-MIB::sonetSectionStatus

OID (numeric): 1.3.6.1.4.1.326.2.2.1.1.4.1.1.1.13

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This variable indicates the Section Status of the interface. It is defined in the SONET IETF draft section configuration table as sonetSectionStatus. The variable is a bit map represented as a sum, therefore, it can represent multiple defects simultaneously. The sonetSectionNoDefect should be set if and only if no other flag is set. The various bit positions are: 1 sonetSectionNoDefect 2 sonetSectionLOS Loss Of Signal was detected. LOS is declared when 20 +/- 3us of all zero patterns is detected. 4 sonetSectionLOF Loss Of Frame was detected. LOF is declared when an out-of-frame condition persists for 3ms.

What is sonetSectionStatus?

A bitmapped summary of Section-layer defects on this port: bit 2 for Loss Of Signal (LOS, ~20us of all-zero pattern) and bit 4 for Loss Of Frame (LOF, an out-of-frame condition persisting 3ms), with a value of 1 meaning no defect. An admin reads this as a quick health check before digging into the individual counters in sonetSectionTable.
