Link
Purpose
Displays all MPLS-TP or ENP links. These links can be equivalent to sections, created via the Section Management dialog, or they are links created via the Create Link dialog, whose endpoints are MPLS-TP interfaces, including VLAN sub-interfaces with usage set to MPLS-TP.
An ENP link has a bandwidth attribute (Available BW) used for the LSP path computation. The default link bandwidth is computed from the physical port characteristic of the end points. The user can overwrite this default bandwidth for the LSP path computation by modifying the “Link BW” value.
A link based on a VLAN sub-interface has a bandwidth attribute specified during creation of the VLAN sub-interface.
Allows you to modify the following Link parameters via the Link Details (dialog window) dialog:
− Name,
− Link Bandwidth (Total BW),
− Use for Routing,
− Cost.
The Link’s Name and Cost are taken from the section as default values upon link creation. Once created they are not related to the section anymore. The section and the link names and costs can be modified independent of each other.
A subset of the entries in the Link table is filtered with the Class Type Filter on the left hand side (see ENP Main Window).
Please note:
An ENP link is removed from ENP when:
• The user deletes the section.
• The user removes one of the ENP interface end points.
• The user removes one of the NE endpoints from the ENP domain.
• The user deletes one of the NE endpoints.

Informational content
Name | The specified link Name as configured via section management or via link creation. Note: There is only one name per link, independent of the Class Type. An existing section name is only taken as the default name upon link creation. |
A End NE | The A End NE. |
A End TP | The A End Termination Point Label or unit/slot#/MPLS-TP port#. If this is a VLAN sub-interface, the VLAN is also shown. |
Z End NE | The Z End NE. |
Z End TP | The Z End Termination Point Label or unit/slot#/MPLS-TP port#. If this is a VLAN sub-interface, the VLAN is also shown. |
Status | The link status. A link with a status other than “Valid” usually requires operator intervention. More information on possible reasons for a non-valid link can be found in “Link Details…”. Possible actions are “Synchronize Link” or “Reset Bandwidth”. The link status can be - Missing Section: No physical section exists for the link. Use the context menu option “Create Section”. - Missing Interface: An interface (mplsif) of the link is missing. - Missing Section and Interface: Both section and interface(s) are missing and need to be created for the link getting valid. |
BW Enforcement | Indicates whether bandwidth enforcement is applied or not. BW enforcement is possible when a HQoS profile has been applied to the link and/or the NEs terminating the link. The following options are possible: - Enabled: all “BW Enforcement” options are enabled on the link; - Disabled: None of the “BW Enforcement” options are enabled on the link; - Partial Enabled: Some of the “BW Enforcement” options are enabled on the link, some aren’t; - Unsupported: HQoS (egress shapers) not supported on the link; - Unknown: Default status (as long as ENP is not synchronized with the NE). |
Supervision | Service Supervision status, - Running: this link is supervised. Supervision can be paused or disabled via the “Supervision ► Pause” or “Supervision ► Disable…” commands in the context menu or the “Edit” menu. - Paused: service supervision is paused on this link. It can be resumed via the “Supervision ► Resume” command in the context menu or the “Edit” menu. - Disabled: service supervision is disabled on this link. It can be enabled via the “Supervision ► Enable…” command in the context menu or the “Edit” menu. |
Superv. Oper State | Shows the operational state (up, down) of the service supervision on this link. This field is empty when service supervision is disabled. |
Fault State | Shows the highest active fault state of the link. |
Oversubscription [kbit/s] | Shows the amount of over-subscription in kbit/s of the link bandwidth if any over-subscription is present. The column is only visible if over-subscription occurs on at least one link. |
Encryptable | Indicates the capability of the link to encrypt tunnels / tunnel segments. Options are: - None: tunnel cannot be encrypted. - A End: tunnel can be encrypted only on A End. - Z End: tunnel can be encrypted only on Z End. - A/Z End: tunnel can be encrypted on both ends. |
RDM BW Used / Total [kbit/s] | Link bandwidth for RDM model-based services. The used bandwidth vs. total bandwidth are shown as numeric values and as a graphical bar. |
MAM BW Used / Total [kbit/s] | Link bandwidth for MAM model-based services. The used bandwidth vs. total bandwidth are shown as numeric values and as a graphical bar. |
Reserved BW [kbit/s] | Total reserved bandwidth of all configured (saved in the database or deployed) Tunnels using this link. Note: When a link carries Tunnels with BFD (Bidirectional Forwarding Detection) Sessions, a bandwidth of 10 kbit/s per tunnel with active BFD is added to the Reserved BW of the link. |
Distinct | Indicates whether the link is a distinct link or not. If distinct, the link is used as physically separate link for working and protected LSPs. |
Controls (buttons, menu items, etc.)
Edit
Create Link |  | Calls the Create Link dialog. |
Link Details… |  | Calls the Link Details (dialog window) dialog. In this dialog you can edit / modify some of the link parameters for a selected Class Type. |
Open A End NE <user class>… | Open the NE configuration of the A End NE of the link. You need to select the user class in the sub menu. The FOXCST GUI will open in a new window. | |
Open Z End NE <user class>… | Open the NE configuration of the Z End NE of the link. You need to select the user class in the sub menu. The FOXCST GUI will open in a new window. | |
Split Link… | This command is only available when Expert Mode is enabled (see Options - Expert Mode). Opens the “Split Link” dialog. In this dialog you can split an existing link to insert a new NE. | |
Create Section | For a link without section, a section can be created. For links with an underlying section this command is not available. | |
Manage Tunnel… | This command is only available when Expert Mode is enabled (see Options - Expert Mode). Opens a dialog to manage all tunnels on the selected link. Any selected tunnel(s) can be: - edited (also see Modify Tunnel…), - automatically re-routed if required, - saved, - deployed, - reset, as far as their current configuration status is appropriate for any of these actions. E.g. a deployed, non-modified tunnel cannot be saved or deployed. Note: When you edit a tunnel, its Status can become “Deployed Invalid” because it has been “Deployed” but some parameters have been modified. In order to get back to a valid state you should Deploy the changes by selecting the tunnel and choose “Deploy Tunnel”. | |
Synchronize Link |  | Synchronize the settings for the selected link as they are present to the database. |
Reset Bandwidth | You can reset the Link Bandwidth to the originally configured value If you have modified the bandwidth of the link. | |

Delete Link… |  | Delete the selected link. This will cause all tunnels over this link to get invalid and will delete the underlying section. You need to confirm this action. |
Create a new dashboard in the metrics database application for the selected link. This will execute a script on the server to create a performance monitor. The dashboard with the given “Link_name” will appear in the Metrics Database in the tab “Boards”. Start and end of the execution will be logged in the event list. | ||

• Initiator NE Drop Profiles with
− Index,
− Threshold,
− Status.
• Terminator NE Drop Profiles with
− Index,
− Threshold,
− Status.
With the “Edit” icon Drop Profiles can be added (as long as the maximum is not reached) and/or deleted. When adding a Drop Profile the Threshold for the new profile is requested.
While in Edit mode, the “Set Change on Both Side” option defines how the changes are applied, either to one end of the link only, or to both ends.
