Issue/Introduction


Spectrum has a series of events that are used when an outage occurs to determine the cause of the outage and
   to suppress alarms on devices upstream/downstream that are not reachable due to the faulting device. Editing
   these event id's can and often results in undesirable results when a fault occurs. These events should not be
   edited and left with their out of the box settings.


One such example where downstream devices were not suppressed.

Environment

Release : All Supported Relases

Component : SPCAEM - Events and Alarms

Cause

Modification of events used in Fault Isolation to determine the root cause of an outage.

Resolution

Restore Fault Isolation events back to their out of the box values.

LINK_GOOD = 0x00010d10,
LINK_BAD = 0x00010d11,
LINK_DISABLED = 0x00010d12,
LINK_UNKNOWN = 0x00010d13,
LINK_UNREACHABLE = 0x00010d14,
LINK_INITIAL = 0x00010d15,
LINK_BAD_SUPPRESSED = 0x00010d16,
LINK_LL_IN_MAINTENANCE = 0x00010d2e,
LINKED_PORT_BAD = 0x00010d17,
LINKED_DEVICE_BAD = 0x00010d18,
LINK_STATUS_CLEAR = 0x00010d2a,
LINK_DISABLED_AND_BAD = 0x0001040d,
LINK_ALWAYS_DOWN = 0x00010d2f,
LINK_BAD_WA_LINK_BAD = 0x00010d2d
CS_EVENT_ALARM_SET = 0x00010701
CS_EVENT_ALARM_UPDATED = 0x00010703
CS_EVENT_DEVICE_LOST = 0x00010302
DEVICE_CONTACT_STATUS_LOST = 0x00010d35
DEVICE_GATEWAY_UNREACHABLE = 0x00010d36
MGMT_LOST = 0x00010d00
UNRESOLVED_FAULT = 0x00010d05
APPLICATION_LOST = 0x00010d09
APPLICATION_REACTIVATED = 0x00010d0b
MGMT_REACTIVATED = 0x00010d0c
DEV_MNGMNT_NBORS_DOWN = 0x00010d19
LANDSCAPE_CONTACT_STATUS_CLEAR = 0x00010d20
PORT_LOST = 0x00010d66
PORT_REACTIVATED = 0x00010d67
ALARMING_MGMT_LOST_EVENT = 0x10daa


Customizing the above events would have direct impact on Fault Isolation (FI)/ Internal Port Link Status (IPLS).
