Logical View
About the Logical View Page
To access this page, click the Monitor tab and then select Logical View from the left-nav bar.
The Logical View page lets you view the logical grouping and logical connectivity in your network.
Tasks You Can Perform
You can perform the following tasks from this page:
View the logical groups (such as ROADM nodes) in your network.
View the connectivity between and within logical groups.
Show or hide different elements from the view.
Navigating the Logical View Page
Use this procedure to navigate the Logical View page. The Logical View page displays connectivity between and within ROADM nodes.
A ROADM node is displayed generically as a device group 
, which is a collection of
one or more devices. The number of devices contained inside the device
group is shown by a number in the upper left corner of the device
group icon. Currently, the only device group that can hold more than
one device is a ROADM node.
When you first open the Logical View page, the device groups are centered on a blank background and set to a level of magnification that allows all device groups to be displayed.
- Use the Select drop-down list to include or
exclude specified entities from view:
Show Mux/Demux - Check to show multiplexers/demultiplexers, uncheck to hide multiplexers/demultiplexers.
Show ILAs - Check to show ILAs, uncheck to hide ILAs. If ILAs are hidden, the links that go through the ILAs are displayed between the ROADM endpoints.
Show Transponders - Check to show transponders, uncheck to hide transponders.
Show Un-Connected - Check to show unconnected devices, uncheck to hide unconnected devices. An unconnected device is a device with no configured or learned links. Note that a connected device can appear unconnected when the device at the other end of the connection is hidden. In other words, if you hide unconnected devices, you might still see devices that appear unconnected if they are connected to a hidden device.
Note In general, when a device is hidden, any links that connect to the device are also hidden. The exception to this is the ILA device, where a connection that spans hidden ILAs is shown as a link between the two ROADM endpoints. This allows you to view ROADM to ROADM connectivity without cluttering the view with amplifiers. A connection that spans hidden ILAs is called an amplified link.

Viewing a Device or Device Group
Use this procedure to view information on a device or a device group.
- To see information for a device group, click the device
group.
An information window appears in the upper left corner. The following information is shown:
The number of devices within the device group.
Note A multiplexer/demultiplexer is part of a ROADM device and is not counted as a separate device.
A visual indication of the number of alarms collectively raised at each severity for all devices in that device group.
A list of devices that belong to that device group. Click a column heading to sort the list by that column. If the list is long, use the Next and Previous buttons to page through the list.
To see information on a device within the list, click a device in the device list. The information window is extended to display device information. Alarm counts are displayed and a shortcut is provided to allow you to click to the Device Config page for that device.
To close the information window, click
.
- To show the contents of a device group, double click the
device group. The device group is expanded and the contained devices
are shown within a shaded device group box. The size of the device
group box is automatically set and cannot be changed.
To see information on a device within the group, hover over the device with your mouse.
To bring up an information window for a device, click the device. An information window appears in the upper left corner showing the alarm counts for the device. From here, you can click a shortcut to go to the Device Config page for that device.
To move a device within a device group box, click and drag the device within the device group box.
To hide the contents of a device group, double click the shaded device group box.
Viewing Link Details
Use this procedure to view information on a link. The color and state of a link are derived from the administrative state and operational status at each endpoint of the link (Table 1).
Table 1: Link Colors and States
Endpoint 1 | Endpoint 2 | Link Color | Link State | ||
|---|---|---|---|---|---|
Administrative State | Operational Status | Administrative State | Operational Status | ||
Out of Service | Down | Out of Service | Down | Black | OOS-Down |
In Service | Down | In Service | Down | Red | IS-Down |
In Service | Down | Out of Service | Down | Red | IS-Down, OOS-Down |
In Service | Up | In Service | Up | Green | IS-Up |
All other combinations | Gray | – | |||
Links are drawn with different weights, as shown in Table 2:
Table 2: Link Weights
Link | Weight |
|---|---|
Links between ROADM nodes | Heavy |
Links between TCX1000-RDM20 devices within a ROADM node | Medium |
All other links | Light |
- To see information on a link, click the link.
The Links window appears in the upper left corner. The following information is displayed:
The source and destination device names and/or IP addresses, depending on user preferences. For amplified links, the source and destination refer to the ROADM device endpoints.
The source and destination port endpoints. For amplified links, the source and destination refer to the ROADM line port endpoints.
The link state. For amplified links, the link state is derived from the state of the ROADM port endpoints.
The fiber type (applicable to line spans only).
