Manage Topological Link

Network topology is the arrangement of the various elements (links, nodes, etc.) of a network.

To manage Topological Links (TLs) of type namely SDH, OTN, OTN-DWDM, Ethernet, and DWDM, go to Topology menu and click Manage TL option. Manage Topological Links page is displayed with a list of topological links.

NOTE: TL type is the Topological Link type selected while creating topological link on Topology View window. For more information, refer to the topic Create Topological Link.

Manage Topological Links page- TOPOLOGICAL LINKS

To manage Amplifier trunks, click AMPLIFIER TRUNKS tab on Manage Topological Links page. A list of amplifier trunks is displayed.

To manage Cloud links, click CLOUD LINKS tab on Manage Topological Links. A list of cloud links is displayed.

Topological Links/Amplifier Trunks/Cloud links parameters

Parameter	Description
TL ID	Displays the identification number assigned to the topological link. This parameter is not applicable to amplifier trunks.
Parent TL ID	Displays the TL ID on which the amplifier trunk has been created. This parameter is applicable only to amplifier trunks.
Amplifier Trunk ID	Displays the identification number assigned to the amplifier trunk. This parameter is only applicable to amplifier trunks.
Local EMS	Displays the source node related EMS name.
Local Node Name	Displays the name of the source node.
Local IP	Displays the IP address of the source node on which the TL is present. Click the link to open the node on manage nodes page.
Local Port	Displays the port number on the source node on which the TL is present.
Local Port PM State	Displays whether the PM at the local port is enabled or disabled.
Local Port PM Granularity	Displays the PM interval selected at the local port.
Local Port PM Enabling Time	Displays the date and the time of PM enabling on the local port.
Remote EMS	Displays the destination node related EMS name.
Remote Node Name	Displays the name of the destination node.
Remote IP	Displays the IP address of the destination node on which the TL is present. Click the link to open the node on manage nodes page.
Remote Port	Displays the port number on the destination node on which the TL is present.
Remote Port PM State	Displays whether the PM at the remote port is enabled or disabled.
Remote Port PM Granularity	Displays the PM interval selected at the remote port.
Remote Port PM Enabling Time	Displays the date and the time of PM enabling on the remote port.
Direction	Displays whether the topological link is unidirectional or bidirectional. This parameter is not applicable to amplifier trunks.
BW Threshold in Percentage	Double-click to enter the bandwidth threshold value for the selected TL. This parameter is not available on amplifier trunks tab.
UserLabel	Displays the name assigned to the topological link/amplifier trunk.
State	Displays the state of the TL as: OPERATIONAL: This is the default state of the TL when it is created. The TL can be edited and new circuits can be created using the ports of that TL which is in OPERATIONAL state. MAINTENANCE_FOR_EDIT: Any operation can be performed on TL i.e., TL can be edited and new TL can be created using the ports of the TL which is in MAINTENANCE_FOR_EDIT state. MAINTENANCE: The TL cannot be used for editing and creation of circuits/TL using the ports of that TL which is in MAINTENANCE state.
Constraint	Displays the constraint of the TL as: NONE: The TL can be included in the circuit creation. GLOBAL_EXCLUDE: The TL cannot be used in the circuit creation. GMPLS_GLOBAL EXCLUDE: The TL cannot be used in the GMPLS circuit creation.

Filtering Topological Links

Perform the following steps to search TLs based on the filtering criteria available:

On Manage TL page, switch ON the Hide Filters button. The filtering criteria are displayed:
- Node/IP: To filter TL based on IP address, select Node check box and enter the local IP or remote IP address in IP field; or to filter TL by node name, enter the local node or remote node name in IP field. On entering a text, a list of options related to that text is displayed and the user can select from the options.
- Port (ci-si-pn): Select the desired port. This field is enabled when a node name or IP is entered in the IP field.
- Capacity: To filter TL based on capacity, select any capacity level from the drop down options namely STM1/OC3, STM4/OC12, STM16/OC48, STM64/OC192, OTU1, OTU2, OTU2e, OTU1f, OTU3, OTU4, Ethernet10MB, Ethernet100MB, Ethernet1GB, Ethernet10GB, Ethernet100GB.
- Directionality: To filter TL based on directionality, select UNIDIRECTIONAL or BIDIRECTIONAL from the drop-down option as desired.
- TL Type: To filter TL based on TL type, select any one of the following TL type from the drop-down option:
  > Convert to System TL: Filters the Manual TLs that can be converted to offline trunks at EMS level. Manual TL will be automatically converted to System TL when the physical connectivity is present.
  
  > Higher Order TL: Displays the higher order topological links created.
  
  > Offline TL: Displays the trunks created on EMS and NMS levels only.
  
  > Online TL: Displays the trunks created on EMS, NMS and node levels.
  
  > Across EMS TL: Displays trunk between nodes across different EMS.
  
  > Radio TL: Displays all the radio trunks present.
  
  > Ethernet TL: Displays all the L2 or packet topological links.
  
  > DWDM TL: Displays all the DWDM topological links.
  
  > OTN TL: Displays all OTN topological links.
  
  > SDH TL: Displays all STM/OC topological links.
  
  > CEM TL: Displays all the circuit emulation topological links.
  
  > OSC TL: Displays all the OSC topological links. This option is not supported for this release.
- User Label: To filter TL based on trunk label, enter the label in the text box provided.
- EMS Name: To filter TL based on the EMS in which it is present, select the EMS from drop-down option.
- Partition Label: To filter TL based on the partition in which it is present, select the partition label from drop-down option.
- Cloud Name: To filter Cloud link based on the cloud name, select the option from drop down menu. This option is only available under CLOUD LINKS tab.
On AMPLIFIER TRUNKS tab, a first level search can be performed based on Node/IP and Port (ci-si-pn).
After entering the desired filtering criteria, click Filter. The result is displayed on Manage Topological Links page.
Click Reset to clear the search criteria.

Topological links can also be filtered by enabling inline filtering option. On Manage Topological Links page, click Show inline filtering check box provided on lower left corner of the page. After enabling, a filter is displayed against each attribute on Manage Topological Links page. User can then perform a search based on the desired attribute. Enter the desired criteria in the text box displayed. The filtered option will be displayed.
