Overview

Lists the elements and UI features available in the network tree and their descriptions.

Table 1. Feature History
Feature Name	Release Information	Feature Description
Network Tree Enhancements	Cisco ONP Release 5.2	Now, you can use the Ellipsis icon at the right side of each element in the Network tree to perform various actions such as Expand All, Collapse All, Enable Multi-Select, and so on. Also, you have multiple entity-level options to filter the elements under the Network tree. These enhancements make the Network tree more intuitive.

The left pane of the Cisco ONP home page comprises a network tree. The network tree includes various network elements. When you click each element, the respective property is displayed under the network tree. You can edit the properties. For more information on editing the network properties, see Modify Network Properties.

From R25.1.1, the network tree provides the UI enhancements

Default multi-select check boxes—network tree entities have the multi-select check boxes enabled by default. To disable the multi-select check boxes, click the ellipses icon and click the Disable Multi-Select option. To enable the multi-select option, follow the same navigation.
Coloring indication on network tree—network tree entities display red, green, and yellow colors to indicate the optical feasibility of the circuits and overall network.

Table 2. Network Tree Elements
Network Tree Elements	Description
Network name	Displays the name of the network.
Sites	Customer premise equipment that is located in a rack within a building. When you click a site name in the network tree, the site will be highlighted in orange on the map. When multiselect is enabled, the network tree displays checkboxes for each site, fiber, and circuit. Selecting multiple sites from the network tree highlights the same sites on the map.
Fiber	Optical fiber connecting two sites.
Fiber Couple	A fiber couple consists of two different fibers (clockwise and counterclockwise), one for transmission and another for reception.
Services	Service is the circuit through which traffic flows between nodes. When you add services to the Traffic site (of the type 1K-2K-4K) in an SSON network, a DefaultGroup is created under the Services in the network tree. You can also create a new service group.
Waves or Medial Channel or Circuits	The wave or Media channel represents a DWDM channel. In a wave hierarchy, for each wave, there is a trail. When you expand a trail, there is a section under each trail. The trail is an optical path or a network section joining two traffic nodes. It can have more than one section depending on whether the trail has a regenerator site. For more information on regeneration, see Regenerator sites.
SRLG	Shared Risk Link Group (SRLG) is useful for routing the protected services. If there are Fiber 1 and Fiber 2 in the network, they are assumed to be diverse and are used as alternates for protection purposes. If Fiber 1 and Fiber 2 are in an SRLG, they are not true alternates, and they share the same risk of failure. Therefore, if Fiber1 fails, Fiber 2 also fails, and Fiber 2 cannot be used as a protected path.
Optical subnet	An optical subnet is a collection of spans with certain associated properties. When you create a new network, Cisco ONP automatically creates an optical subnet that is associated to the network. At least one optical subnet must exist for each network.

Use the Search box on top of the network tree to search for any specific site, fiber, or wave in the network tree panel. Click the Refresh icon to refresh your search.

Now, you can filter the elements available in the network tree using the Filter icon available next to the Search box. The following table explains the various filter options available.

Table 3. Network Tree Elements
Filters	Options Available Under Each Filter
Network Filter	Entity Type
Sites Filter	Site Type, and DWDM Site Type
Fibers Filter	Source Site, Destination Site, Source Edge, Destination Edge, and Raman
Services Filter	Protection Type, Source Site, Destination Site, Src Add-Drop Type, and Dst Add-Drop Type
Waves, Medial Channel, or Circuits Filter	Protection Type, Source Site, Destination Site, Src Add-Drop Type, and Dst Add-Drop Type
