(ONS 15454 only) Use the LMP > Data Links subtab to define the transport parameters of the node. CTC
supports up to 256 LMP data links. For information about creating, editing, or deleting LMP Data Links see:

Displays the state of LMP operation. The state of an LMP data link is derived from the service state of the client port with which it is associated. A service state of IS is mapped to the data link state of Up. Any other service states are mapped as Down:
• |
Unknown —Indicates that LMP is not enabled. |
• |
Up —Indicates that LMP is enabled and the link is active. |
• |
Up-Alloc —The Up-Alloc data link is allocated for data traffic. |
• |
Up-Free —The Up-Free data link is not allocated for traffic. The remote node is either not ready to receive traffic through this port, or the path is being used as a backup in case some other allocated data link goes down. |
• |
Down —Indicates that LMP is enabled and the link is inactive. |
Tips: If data link state does not transition to Up-Alloc or Up-Free:
• |
Check that the port is in-service. This has to be done from the port provisioning tabs. The data link will be in the Down state if the port is not IS. Changing the state of the port will impact the state of a data link using the port. |
• |
Check that you are using the correct Remote Port ID for the far end data link. |
• |
On the remote node, check that the data link is using the Local Port ID as the Remote Port ID. |

Displays the Slot # and Port # selected from the drop-down list in the Create LMP Control Channel dialog box.
|
|
Displays the local port identifier assigned by the node.
|
|
Displays either Port or Component which can be chosen in the Create LMP Data Link dialog box.
A data link is considered as either a port link or a component link by each node that it terminates on, depending on the multiplexing capability of the endpoint on that link. Component links are multiplex capable. Ports are not multiplex capable.
