Chapter 6 Create Circuits and VT Tunnels
NTP-A134 Create a Manually Routed VT Tunnel
Step 14
If you selected Using Required Nodes/Spans in
:
a.
Click
Next
.
b.
In the Circuit Route Constraints area, click a span on the VT tunnel map.
c.
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.
d.
Repeat Steps b and c for each node or span you wish to include or exclude.
e.
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.
Step 15
If you selected Review Route Before Creation in
a.
Click
Next
.
b.
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.
c.
If the provisioned tunnel does not reflect the routing and configuration you want, click
Back
to
verify and change tunnel information.
Step 16
Click
Finish
. The Circuits window appears.
Step 17
Verify that the tunnel you just created appears in the circuits list. VT tunnels are identified by VTT in
the Type column.
Stop. You have completed this procedure.
NTP-A134 Create a Manually Routed VT Tunnel
Note
VT tunnels allow VT circuits to pass through intermediary ONS 15454s without consuming VT matrix
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.
Step 1
Complete the
“DLP-A60 Log into CTC” task on page 17-66
at the node where you will create the VT
tunnel. If you are already logged in, continue with
Step 2
If you want to assign a name to the tunnel source and destination ports before you create the circuit,
complete the
“DLP-A314 Assign a Name to a Port” task on page 20-8
. If not, continue with
Purpose
This procedure creates a manually routed VT tunnel from source to
destination nodes.
