Field Descriptions for the Discovery Information Table

 

 

 

Field

 

Description

 

 

 

Discovered NE

 

NE system ID of the NE selected for discovery, or Main for the main discovery.

 

 

 

Start Time

 

Discovery start time. When the element name is an NE system ID, the elapsed time between start time and

(time stamp)

 

end time represents the amount of time required to discover the individual device. When the element name

 

 

is Main, the elapsed time between the start time and end time includes:

 

 

The time required to discover all of the individual NEs that participated in the current discovery cycle

 

 

The time required for the network-level computations for topology, discrepancy, and logical circuits

 

 

 

End Time

 

Discovery end time (if the discovery has completed).

(time stamp)

 

 

 

 

 

Status

 

Status of the discovery (whether it succeeded, failed, or is in progress). The status “idle” means that no

 

 

discovery has ever occurred on the NE.

 

 

 

Start Mode

 

How the discovery was started (periodic rediscovery, user-requested discovery, or discovery triggered by

 

 

an update).

 

 

 

Description

 

Type of discovery that was performed. If the discovery fails, this column includes a description of the cause

 

 

of the failure.

 

 

 

3.8.3 Rediscovering ONS 155xx, CRS-1, and XR 12000 NEs

The Rediscover and Rediscover All commands perform a rediscovery of selected ONS 155xx, CRS-1, or XR 12000 NEs or of the entire ONS 155xx, CRS-1, or XR 12000 network. Rediscovery updates CTM with current network-level information (such as physical topology, logical circuits, and discrepancies) and device-level information (such as inventory and alarms).

Note Periodic rediscovery occurs every 24 hours, and certain changes on the device can trigger incremental rediscovery.

Start rediscovery from any of the following windows:

Domain Explorer

Subnetwork Explorer

Network Map

Note Only users with the appropriate privileges can use the Rediscover All command.

Step 1 To rediscover selected NEs, select NEs or groups of NEs and choose Configuration > ONS 155XX, Cisco CRS-1, or Cisco XR 12000 > Rediscover.
