Alarm Collection and Display

Cisco ONS 15454 SDH Product Overview, R3.4

September 2002

• Node subtab—Shows alarm and event messages that occurred at the node

since the CTC software installation, and also alarm and event messages for

the current CTC session. The ONS 15454 SDH can store up to 640 critical

alarm raise/clear messages, 640 major alarm raise/clear messages, 640 minor

alarm raise/clear messages, and 640 events. When the limit is reached for a

category, the ONS 15454 SDH discards the oldest alarms and event-level

raise/clear/transient messages in that category.

Alarm Profiles

The ONS 15454 SDH includes an alarm profile feature, accessible from the CTC

network view. This feature allows you to change the default alarm severities (for

example, from minor to major) and apply the new severities at the card, port, or

node level. Alarm profiles for a given card can be viewed in the Alarm Behavior

tab in the CTC card view.

CTC also has a network element (NE) default feature that allows you to change

port and card level default settings for the ONS 15454 SDH from one convenient

location. This feature can be accessed from the Provisioning > Defaults Editor

tabs in the node view.

In addition to user-defined profiles, CTC stores a default profile that sets severities

to standard ITU-T G.783 settings. To create a new profile, clone the default in

CTC, rename it, and choose the severity settings for the new profile.

Alarm Suppression

From the card view, you can suppress alarms on specific ports. From the node

view, you can suppress alarms on specific cards or on the entire node.

If alarms are suppressed, they do not appear on the CTC Alarm screen. On the

History screen, a message states that the alarms are suppressed, and the

Conditions tab shows the suppressed alarms. The node sends out autonomous

messages to clear any raised alarms. When alarm suppression is turned off, the

node sends out autonomous messages to raise any suppressed alarms that are still

active.
