3.8.3 Rediscovering ONS 155xx, CRS-1, and XR 12000 NEs
all types of discovery: periodic rediscovery, user-requested rediscovery, and update-triggered discovery.
To view the table, choose Configuration > ONS 155XX > Discovery Info Table in the Domain
Explorer.
Table 3-17 describes the fields in the Discovery Information table.
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.
Table 3-17 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
(time stamp)
Discovery start time. When the element name is an NE system ID, the elapsed time between start time and
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
(time stamp)
Discovery end time (if the discovery has completed).
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.
