15.9.3 LMP WDM
LMP manages traffic engineering links between peer nodes (nodes that are peers in signaling and/or
routing). The purpose of the LMP WDM extensions
and an adjacent DWDM OLS node.
LMP-WDM. OXC 1 and OXC 2 are peer nodes whose control channel is managed with LMP.
LMP-WDM manages the control channel between an OXC node and an OLS node.

OXC 1
When the two OLS nodes can communicate their configuration and the current state of their optical link
to the two peer nodes (OXC 1 and OXC 2) through LMP-WDM, network usability is improved through
the reduction of manual configuration and enhanced fault detection and recovery.

LMP and other features allow the Cisco ONS 15454 DWDM node to fulfill the ULH DWDM role.
