Cisco ONS 15454 Procedure Guide, R5.0
August 2005
Chapter 6 Create Circuits and VT Tunnels
NTP-A134 Create a Manually Routed VT Tunnel
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.
–
OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance
state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks
to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms
temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is
complete. See the
“DLP-A230 Change a Circuit Service State” task on page 19-19
Note
A VT tunnel automatically transitions into the IS service state after a VT circuit is created.
For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter
in the
Cisco ONS 15454 Reference Manual
.
•
Apply to drop ports—Unavailable for VT tunnels.
Step 8
Click
Next
.
Step 9
In the Circuit Source area, choose the node where the VT tunnel will originate from the Node drop-down
list.
Step 10
Click
Next
.
Step 11
In the Circuit Destination area, choose the node where the VT tunnel will terminate from the Node
drop-down list.
Step 12
Click
Next
.
Step 13
In the Circuit Routing Preferences area, uncheck
Route Automatically
.
Step 14
Click
Next
. In the Route Review and Edit area, node icons appear so you can route the tunnel. The circuit
source node is selected. Green arrows pointing from the source node to other network nodes indicate
spans that are available for routing the tunnel.
Step 15
Complete the
“DLP-A219 Provision a VT Tunnel Route” task on page 19-13
for the tunnel you are
creating. The Circuits window appears.
Step 16
Verify that the tunnel you just created appears in the circuits list. VT tunnels are identified by VTT in
the Type column.
