NTP-A78 Create a Monitor Circuit
Step 2 As needed, complete the “DLP-A332 Change Tunnel Type” task on page 20-20.
Step 3 As needed, complete the “DLP-A336 Repair an IP Tunnel” task on page 20-23.
Step 4 As needed, complete the “DLP-A334 Delete Overhead Circuits” task on page 20-22.
Stop. You have completed this procedure.
NTP-A78 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-A60 Log into CTC” task on page 17-66 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 (two-way) circuit that you want to monitor and 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 displays ports that you can use to monitor the circuit.
Note The Monitor tab is only available when the circuit has a DISCOVERED status.
Step 7 On the Monitors tab, choose the monitor source port. The monitor circuit will display traffic coming into
the node at the port you choose.
Note In Figure 9-1, you would choose either the DS1-14 card (to test circuit traffic entering Node 2
on the DS1-14) or the OC-N card at Node 1 (to test circuit traffic entering Node 1 on the OC-N
card).
Purpose This procedure creates a monitor circuit that monitors traffic on primary,
bidirectional circuits.
Tools/Equipment None
Prerequisite Procedures Bidirectional (two-way) circuits must exist on the network. See Chapter 6,
“Create Circuits and VT Tunnels” for circuit creation procedures.
Required/As Needed As needed
Onsite/Remote Onsite or remote
