Module: Nortel-MsCarrier-MscPassport-ExternalTimingDS1MIB

OID (symbolic): Nortel-MsCarrier-MscPassport-ExternalTimingDS1MIB::mscLpEDS1AlarmStatus

OID (numeric): 1.3.6.1.4.1.562.36.2.1.12.28.15.1.7

Node type: OBJECT-TYPE

Access: read-only

Description: If supported by the component, this attribute indicates the OSI Alarm status of the component. Note that, even though it is defined as a multi-valued set, at most one value is shown to the user.

When no values are in the set, this indicates that either the attribute is not supported or that none of the status conditions described below are present.

The value underRepair indicates the component is currently being repaired. The operationalState is enabled or disabled.

The value critical indicates one or more critical alarms are outstanding against the component. Other, less severe, alarms may also be outstanding. The operationalState is enabled or disabled.

The value major indicates one or more major alarms are outstanding against the component. Other, less severe, alarms may also be outstanding. The operationalState is enabled or disabled.

The value minor indicates one or more minor alarms are outstanding against the component. Other, less severe, alarms may also be outstanding. The operationalState is enabled or disabled.

The value alarmOutstanding generically indicates that an alarm of some severity is outstanding against the component.

Description of bits: underRepair(0) critical(1) major(2) minor(3) alarmOutstanding(4)

What is mscLpEDS1AlarmStatus?

This object is an OSI Alarm Status bitmap for the EDS1 component, indicating whether critical, major, or minor alarms are currently outstanding against it, or whether it's underRepair. Admins use this as a quick severity check when investigating a timing component's health, distinct from the specific alarm conditions reported by other status objects. For example, the critical(1) bit being set would prompt immediate investigation, since it means one or more critical alarms are active on this timing interface.
