Note
Any default node values given in this table can vary depending on the node defaults entered under the Provisioning > Defaults tab.
 
Item
Description
Admin State
The Admin State is the provisioning that tells the node to bring up or disable the link. Choosing an administrative state from the drop-down list and clicking Apply changes the control channel’s operational state unless network conditions prevent the change. Admin states include:
 •
unlocked—Changing the state to unlocked means that the node will try to establish the control channel, negotiate channel parameters, and begin the hello message exchange to bring up the link.
 •
locked,disabled—Removes the control channel from service and disables the link.
Local Port
Choose an option from the drop-down list:
 •
Routed: The control channel is sent over the control plane or management network.
 •
Slot # and Port #: The control channel is in-fiber, meaning that it is sent over the same fiber as the traffic in either the payload or in the overhead.
Local Port Id
Displays the local port identifier assigned by the node.
Remote Node Type
Select 15454 or non-CRS1 to create control channel between two Cisco ONS 15454 nodes or between a Calient PXC and a Cisco ONS 15454 node.
Select CRS-1 to create control channel between a Cisco CRS-1 router and a Cisco ONS 15454 node.
Remote Node IP Address
Enter the IP address of the remote node for which you are creating an LMP control channel.
Remote Node Id
Enter the remote node identifier of the node for which you are creating an LMP control channel. It is possible that the IP address and the node ID will be the same. The field automatically populates if you fill in the Remote Node IP Address first. If you enter the Remote Node ID first, this field will not change. You can change the value in this field according to your site plan, even if it was automatically populated.
Requested Hello Interval
Enter the Requested Hello Interval. The range is 300 to 5,000 ms, the default is 500 ms, and the granularity is 1 ms. The Requested Hello Interval must be greater than the Min Hello Interval and less than the Max Hello Interval. The Requested Hello Interval specifies an interval at which the local node is scheduled to send a hello message to the remote node. This message allows the nodes to know that they are alive and talking.
Min Hello Interval
Enter the minimum hello interval that is acceptable for the local node. The Min Hello Interval must be less than the Requested Hello Interval and less than the Max Hello Interval. The range is 300 to 5,000 ms, the default is 300 ms, and the granularity is 1 ms.
Max Hello Interval
Enter the maximum hello interval that is acceptable for the local node. The Max Hello Interval must be greater than the Requested Hello Interval and the Min Hello Interval. The range is 300 to 5,000 ms, the default is 5,000 ms, and the granularity is 1 ms.
Requested Hello Dead Interval
Enter the requested hello dead interval. The Requested Hello Dead Interval must be at least three times the Requested Hello Interval. Also, the Requested Hello Dead Interval must be greater than the Min Hello Dead Interval and less than the Max Hello Dead Interval. The default is 12,000 ms. The Requested Hello Dead Interval is how long the local node waits before it declares that the remote node is not responding (failed).
Min Hello Dead Interval
Enter the minimum hello dead interval acceptable for the local node. The Min Hello Dead Interval must be greater than the Min Hello Interval. Also, the Min Hello Dead Interval must be less than the Requested Hello Dead Interval and less than the Max Hello Dead Interval. The range is 2,000 to 20,000 ms, the default is 2,000 ms, and the granularity is 1 ms.
Max Hello Dead Interval
Enter the maximum hello dead interval acceptable for the local node. The Max Hello Dead Interval must be greater than the Max Hello Interval. Also, the Max Hello Dead Interval must be greater than the Requested Hello Dead Interval and the Min Hello Dead Interval. The range is 2,000 to 20,000 ms, the default is 20,000 ms, and the granularity is 1 ms.
