Chapter 6 Create Circuits and VT Tunnels
NTP-A133 Create an Automatically Routed VT Tunnel
Stop. You have completed this procedure.
NTP-A133 Create an Automatically 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 want to 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
Step 3
From the View menu, choose
Go to Network View
.
Step 4
Click the
Circuits
tab, then click
Create
.
Step 5
In the Circuit Creation dialog box, choose
VT Tunnel
from the Circuit Type list.
Step 6
Click
Next
.
Step 7
Define the circuit attributes (
•
Name—Assign a name to the VT tunnel. The name can be alphanumeric and up to 48 characters
(including spaces). Circuit names should be 44 characters or less if you want the ability to create
monitor circuits. If you leave the field blank, CTC assigns a default name to the tunnel.
•
Size—Unavailable for VT tunnels.
•
Bidirectional—Unavailable for VT tunnels.
•
State—Choose the administrative state to apply to all of the cross-connects in the VT tunnel:
–
IS—Puts the circuit cross-connects in the IS-NR service state.
–
OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is
not passed on the circuit.
–
IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses
alarms and conditions. When the connections receive a valid signal, the service state
automatically changes to IS-NR.
Purpose
This procedure creates an automatically routed VT tunnel from source to
destination nodes.
