vcAlarmStatus
Module: PEGASUS-SDH-MIB
OID (symbolic): PEGASUS-SDH-MIB::vcAlarmStatus
OID (numeric): 1.3.6.1.4.1.6368.2.8.4.1.11
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: This variable indicates the status of the VC. It's a bitmap represented as a sum. Therefore multiple defects can be displayed simultaneously. The value noDefect should only be set if there is no other defect. Some alarms can't occur actually. The various bit positions are: 1 vcNoDefect 2 vcAlarmAIS 4 vcAlarmLOP 8 vcAlarmRDI 16 vcAlarmUnequipped 32 vcAlarmPLM 64 vcAlarmTIM 128 vcAlarmLOM 256 vcAlarmRFI 512 vcgTxAddTimeout -- not used (deprecated) 1024 vcgTxAdd -- not used (deprecated) 2048 vcgTxRemove -- not used (deprecated) 4096 vcgTxDnu -- not used (deprecated) 8192 vcgDnuOk -- not used (deprecated) 16384 vcgRxAdd -- not used (deprecated) 32768 vcgRxRemove -- not used (deprecated) 65536 vcgRxFail -- not used (deprecated) 131072 vcgLcasCrcError 262144 vcgNonLcasSeqError
What is vcAlarmStatus?
This is a bitmap (summed as an integer up to 524287) of VC-level defects such as vcAlarmAIS, vcAlarmLOP, vcAlarmRDI, vcAlarmUnequipped, vcAlarmPLM, vcAlarmTIM, vcAlarmLOM, vcAlarmRFI, plus LCAS-related bits like vcgLcasCrcError and vcgNonLcasSeqError, with several older vcg* bits marked deprecated/unused; a value of 1 (vcNoDefect) means nothing is active. Admins decode this bitmap to see every concurrent VC-level fault at once, e.g. distinguishing an unequipped VC from a real trace-ID mismatch.
