Conditions


The Conditions tab displays retrieved fault conditions for the network (network view), node (node view), or card (card view). A condition is a fault or status detected by Cisco ONS hardware or software. When a condition occurs and continues for a minimum period, CTC raises a condition, which is a flag showing that this particular condition currently exists on the ONS node.

The Conditions window shows all conditions that occur, including those that are superseded. For instance, if a network problem causes two alarms, such as loss of frame (LOF) and loss of signal (LOS), CTC shows both the LOF and LOS conditions in this window. Having all conditions visible can be helpful when troubleshooting the node. If you want to retrieve conditions that obey a root-cause hierarchy (that is, LOS supersedes and replaces LOF), you can exclude the same root causes by checking the Exclude Same Root Cause check box.

Tip: In node view, you can double-click an alarm to display the card where the alarm occurred.

Item

Description

Date

Date and time of the condition.

Object

TL1 access identifier (AID) for the alarmed object. For HPmon or LPmon alarms, the object.

Eqpt Type

If the alarm is raised on a card, the card type.

Slot

If the alarm is raised on a card, the slot where the condition occurred.

Port

If the alarm is raised on a card, the port where the condition is raised. For HPTerm and LPTerm, the port refers to the upstream card it is partnered with.

Path Width

Indicates how many VC-4s are contained in an alarmed path. (For any non-VC-4 object, such as a VC-3, the column is blank.)

Sev

The condition severity level: CR (Critical), MJ (Major), MN (Minor), NA (Not Alarmed), NR (Not Reported).

SA

When checked, indicates a service-affecting alarm.

Cond

The error message/condition name.

Description

Description of the condition.

Retrieve

Requests the current set of fault conditions. The Conditions tab is not updated when conditions change; therefore, you must click Retrieve to see any changes.

Filter

Displays the Conditions Filter dialog box to filter the conditions that appear on the Conditions tab.

Exclude Same Root Cause

If checked, eliminates all lower-level alarms or conditions that originate from the same cause from the Conditions tab. For example, a fiber break might cause an LOS alarm, an AIS condition, and an SF condition. If you check the Exclude Same Root Cause check box, the AIS and SF conditions are eliminated because the LOS alarm supersedes them. According to Telcordia, exclusion rules apply to a query of "all conditions from a node."

Help

Displays context-sensitive help.
