VT tunnels allow VT circuits to pass through intermediary ONS 15454s without consuming VT matrix
Note
resources on the cross-connect card. VT tunnels can carry 28 VT1.5 circuits. In general, creating VT
tunnels is a good idea if you are creating many VT circuits from the same source and destination. Refer
to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual for more information.

Click Next.
In the Circuit Route Constraints area, click a span on the VT tunnel map.
Click Include to include the node or span in the VT tunnel. Click Exclude to exclude the node or
span from the VT tunnel. The order in which you choose included nodes and spans sets the VT
tunnel sequence. Click spans twice to change the circuit direction.
Repeat Steps b and c for each node or span you wish to include or exclude.
Review the VT tunnel route. To change the tunnel routing order, choose a node in the Required
Nodes/Lines or Excluded Nodes Links lists, then click the Up or Down buttons to change the tunnel
routing order. Click Remove to remove a node or span.
Click Next.
Review the tunnel route. To add or delete a tunnel span, choose a node on the tunnel route. Blue
arrows show the tunnel route. Green arrows indicate spans that you can add. Click a span arrowhead,
then click Include to include the span or Remove to remove the span.
If the provisioned tunnel does not reflect the routing and configuration you want, click Back to
verify and change tunnel information.
This procedure creates a manually routed VT tunnel from source to
destination nodes.
