Adva FSP 3000R7 - About WDM Cross-Connections

Maintaining Tunnels and Services
Step 22 If the requested end-to-end transport connection is not successfully
established: A message window will appear to inform of the failure. Consult the
following resources as necessary to understand what the problem is:
• The Tunnel Flt Log and Fault tabs. The Fault tab show all standing
conditions related to the Tunnel, while the Flt Log lists all conditions that
have occurred on the tunnel or on connections related to the Tunnel. This
log may be used to trace the process of setting up the Tunnel.
• The Control Plane Log Table window (Use Service Logging > Control
Plane Log Table).
• The TE Routers window (Use Control Plane > TE Information >
TERouters). This window gives you access to an overview of all control
plane enabled NEs. If any TE router is incorrectly configured, this can
affect the successful establishment of the requested end-to-end transport
connection. For more information see “Viewing TE Router Information” on
p.556.
• The TE Links Numbered or TE Links Unnumbered window (Use
Control Plane > TE Information > TE Links WDM > TE Links
Numbered or TE Links Unnumbered). This window gives an overview of
transport links with traffic engineering capabilities. The TE links describe
the arcs in the graph representing the transport network topology as
discovered by the control plane. If any TE link is advertised incorrectly,
this can affect the successful establishment of the requested end-to-end
transport connection. For more information see “Viewing TE Link
Information” on p.557.
Step 23 If the requested end-to-end transport connection is successfully established,
the control plane will automatically create connection entities at all network
elements along the paths associated with the originating Tunnel entity. These
connection entities provide each network element that is associated with the
end-to-end transport connection complete visibility to and correlation with that
service.
About WDM Cross-Connections
WDM cross-connections logically associate a channel with some particular application or
use within a network element. An optical channel can originate at, terminate at, or transit
through a network element, and WDM cross-connections indicate which of these uses or
applications employs a given optical channel. While an ADM or ROADM cross-
connection is a one-way connection between two channel entities or network virtual
channels in the management plane, a WDM cross-connection is a logical representation
of a fixed or dynamic cross-connection in the data plane.
The control plane requires WDM cross-connections to identify which WDM channels
within a transport link are currently allocated to some particular use. Therefore, before you
can convert an existing service to control plane management, you must first create WDM
cross-connections for each channel and at each node carrying the service that you wish
to convert.
