Module: ADN-ENV-MIB
OID (symbolic): ADN-ENV-MIB::adnAtmLineDefHierarchy
OID (numeric): 1.3.6.1.4.1.637.3.1.8.5.5.22.1.15
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This indicates the current Defect hierarchy towards the other defects; it is coded as a long integer (i.e 32 bits). There's one bit per defect: - bit #n = 0 : defect n masked (i.e the current defect inhibits the #n one if both are present), - bit #n = 1 : defect n unmasked.
What is adnAtmLineDefHierarchy?
ADN-ENV-MIB::adnAtmLineDefHierarchy is a 32-bit integer that defines which other defects are masked (suppressed) or unmasked (reported) when this defect occurs simultaneously. Network engineers use this to prioritize defect reporting—masking lower-priority defects prevents alarm storms when a major issue already dominates the line. A value like 1073741823 might mask defects 31 through 2 while reporting defect 0, so only the root cause alarm shows up.
