The Conditions tab displays retrieved fault conditions for the network, node, or card. A condition is a
fault or status detected by Cisco Optical Networking System (ONS) hardware or software. When a condition occurs and continues for a minimum period, Cisco Transport Controller (CTC) raises a condition, which is a flag showing that this particular condition currently exists on the ONS node. The Conditions tab does not automatically update to show new conditions; you must use the Retrieve button to refresh the tab.
The Conditions window shows all conditions that occur, including those that are superseded.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.
|
|
|
Displays the date and time of the condition.
|
|
(Network view only) The node where the condition occurred.
|
|
Shows the TL1 access identifier (AID) for the alarmed object. For an STSMON or VT-MON alarms, the object.
|
|
If the alarm is raised on a card, indicates the card type.
|
|
(Network view or multishelf view [multishelf mode] only) When checked, indicates a multishelf condition.
|
|
If the alarm is raised on a card, indicates the slot where the condition occurred.
|
|
If the alarm is raised on a card, indicates the port where the condition is raised. For STSTerm and VTTerm, the port refers to the upstream card with which it is partnered.
|
|
Wavelength is a provisionable parameter on the port entity. If a wavelength is provisioned that does not match the PPM capability, a PROV-MISMATCH alarm occurs. The wavelength is displayed for DWDM and MRC-N (ONS 15454 only) and ASAP (ONS 15600 only) cards.
|
|
Indicates how many STSs are in the path.
|
|
Identifies the condition severity level: CR (Critical, displayed in red), MJ (Major, displayed in orange), MN (Minor, displayed in yellow), NA (Not Alarmed, displayed in pink), or NR (Not Reported, displayed in blue).
|
|
When checked, indicates a service-affecting alarm.
|
|
Shows the error message/condition name.
|
|
Displays a description of the condition.
|
|
Displays the direction (receive or transmit) of the alarm condition and is relative to the entity (node, card, slot, or port) identified by the AID (entity identifier).
|
|
Displays the location (far, near, or N/A) of the alarm condition and refers to the entity (node, card, slot, or port) identified by the AID (entity identifier). Near end refers to alarm conditions occurring at the identified entity, and far end refers to alarm conditions occurring at a distant entity connected to the identified entity.
|
|
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.
|
|
Displays the Conditions Filter dialog box to filter the conditions that appear on the Conditions tab.
|
|
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 alarm indication signal (AIS) condition, and a signal fail (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.”
|
|
Turns the filter on or off. CTC retains that last filter activation setting. For example, if you turn the filter on and then log out, CTC keeps the filter active the next time you log in.
|
|
Displays context-sensitive help.
