6.4 Creating Monitor Circuits
You can set up secondary circuits to monitor traffic on primary bidirectional circuits.
shows
an example of a monitor circuit. At Node 1, a VT1.5 is dropped from Port 1 of a DS-1 card. To monitor
the VT1.5 traffic, test equipment is plugged into Port 2 of the DS-1 card and a monitor circuit to Port 2
is provisioned in CTC. Circuit monitors are one-way. The monitor circuit in
monitor VT1.5 traffic received by Port 1 of the DS-1 card.
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.

Procedure: Create a Monitor Circuit
Step 1
Log into CTC.
Step 2
In node view, select the
Circuits
tab.
Step 3
Select the bidirectional circuit that you want to monitor. Click
Edit
.
Step 4
On the Edit Circuit dialog box, click the
Monitors
tab.
Step 5
The Monitors tab displays ports that you can use to monitor the circuit selected in Step 3.
Step 6
On the Monitors tab, select a port.
The monitor circuit displays traffic coming into the node at the
card/port you select. In
, you would select either the DS1 card (to test circuit traffic entering
Node 2 on the DS1) or the OC-N card at Node 1 (to test circuit traffic entering Node 1 on the OC-N card).
Step 7
Click
Create Monitor Circuit
.
Step 8
On the Circuit Creation dialog box, select the destination node, slot, port, and STS for the monitored
circuit. In the
example, this is Port 2 on the DS-1 card. Click
Next
.
Step 9
On the Circuit Creation dialog box confirmation, review the monitor circuit information. Click
Finish
