NTP- D78 Create a Monitor Circuit
Step 1 Complete the “DLP-D60 Log into CTC” task on page 17-49 for a node on the network where you want
to delete the circuit. If you are already logged in, continue with Step 2.
Step 2 As needed, complete the “DLP-D29 Change Tunnel Type” task on page 17-24.
Step 3 As needed, complete the “DLP-D30 Repair an IP Tunnel” task on page 17-25.
Step 4 As needed, complete the “DLP-D31 Delete Overhead Circuits” task on page 17-25.
Step 5 As needed, complete the “DLP-D207 Delete a Server Trail” task on page 19-5.
Stop. You have completed this procedure.
NTP-D78 Create a Monitor Circuit
Note Monitor circuits cannot be used with EtherSwitch circuits.
Note For unidirectional circuits, create a drop to the port where the test equipment is attached.
Step 1 Complete the “DLP-D60 Log into CTC” task on page 17-49 at a node on the network where you will
create the monitor circuit. If you are already logged in, continue with Step 2.
Step 2 From the View menu, choose Go to Network View.
Step 3 Click the Circuits tab.
Step 4 Choose the bidirectional (2-way) circuit that you want to monitor and double-click it (or click Edit).
Step 5 Verify that the circuit name is no longer than 44 characters. Monitor circuits append a “_MON” to the
circuit name. If the name is longer than 44 characters, edit the name in the Name field, then click Apply.
Step 6 In the Edit Circuit window, click the Monitors tab.
The Monitors tab provides ports that you can use to monitor the circuit. The Monitor tab is only available
when the circuit has a DISCOVERED status.
Step 7 In the Monitors tab, choose the monitor source port. The monitor circuit will show traffic coming into
the node at the port you choose.
Step 8 Click Create Monitor Circuit.
Step 9 In the Circuit Destination section of the Circuit Creation wizard, choose the destination node, slot, port,
and if applicable, VC for the monitored circuit.
Purpose This procedure creates a monitor circuit that monitors traffic on primary,
bidirectional circuits on E1 or STM-1 cards.
Tools/Equipment None
Prerequisite Procedures Bidirectional (2-way) circuits must exist on the network. See Chapter 6,
“Create Circuits and Low-Order Tunnels” for circuit creation procedures.
Required/As Needed As needed
Onsite/Remote Onsite or remote
