Module: Nortel-Magellan-Passport-AtmTrunksMIB

OID (symbolic): Nortel-Magellan-Passport-AtmTrunksMIB::trkAtmMajorVccUtilAlarmThreshold

OID (numeric): 1.3.6.1.4.1.562.2.4.1.60.3.14.1.2

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: This attribute specifies the threshold value at which a major alarm will be issued based on a sustained average ATM VCC utilization as indicated by the lastCalculatedVccUtilization attribute. The Set alarm is issued after 3 minutes of utilization greater than the threshold. The corresponding Clear alarm is issued after a subsequent 3 minutes of utilization less than or equal to the threshold. The value 200% is used to disable this threshold. For values other than 200%, the major alarm threshold must be greater than the minor threshold and less than the critical threshold.

What is trkAtmMajorVccUtilAlarmThreshold?

Sets the sustained ATM VCC utilization percentage (0-200, default 85) at which a major alarm is raised, using the same 3-minute set/clear debounce as the minor threshold. Must remain greater than the minor threshold and less than the critical threshold, unless set to 200% to disable it.
