Step 1 Complete the "DLP-D60 Log into CTC" task on page 17-47 at the node where you want to view the cross-connect card resource usage. If you are already logged in, continue with Step 2.

Step 2 Click the Maintenance > Cross-Connect > Resource Usage tabs.

Step 3 In the Summary area of the Resources Usage tab, view the following information:

VC4 Matrix— (XC10G, XC-VXL-10G, and XC-VXL-2.5G cards) Provides the percent of VC-4 paths and VC-4s dropped to lower order paths that are in use. 384 VC-4s are available with XC10G and XCVXL 10G cross-connect cards; 192 VC-4s are available with XC-VXL-2.5G cards.

TUG3 Matrix Ports—(XC-VXL-10G and XC-VXL-2.5G only) Provides the percent of cross-connect card TUG3 matrix ports that are in use. TUG3 matrix ports are the number of VC-4s that are dropped to lower order paths (using TUG3s to hold VC-3s and TUG2s) shown in VC-4 size. 384 TUG3 matrix ports are available.

TUG3 Matrix—(XC-VXL-10G and XC-VXL-2.5G only) Provides the percent of the TUG-3 matrix resources that are in use. 384 TUG-3 paths are available.

VC12 Matrix Ports—(XC-VXL-10G and XC-VXL-2.5G only) Provides the percent of the VC-12 matrix ports that are in use. VC-12 matrix ports are the number of TUG-3s used to support TUG2s (that is, VC-11s and VC-12s, though only VC-12s are supported in this release). 96 VC-12 matrix ports are available.

VC12 Matrix—(XC-VXL-10G and XC-VXL-2.5G only) Provides the percent of the VC12 matrix resources that are in use. 2016 VC-12 paths are available.

Step 4 In the TUG3 Matrix Port Detail section, click VC12, VC3, or Unused to view the matrix port details:

Drop—Identifies the source slot and port.

Tunnel Name—If the port is used by a tunnel, the tunnel name appears here.

% Used—Shows the percent of the matrix port that is used.

Usage—Shows the port usage.

Step 5 As needed, you can perform the following actions:

Click the Refresh button to update the view. For example, if other users create circuits while you view the Resource Usage tab, click Refresh to see the effects those circuits have on the matrix usage.

Click the Delete button to delete VC12s or VC3s that use matrix resources but no longer carry circuits. This occasionally occurs when many circuits are added and deleted over a period of time. Stranded VC12s or VC3s appear with 0 percent usage in the TUG3 Matrix Port Detail area. If stranded VC12s or VC3s appear, click the VC, then click Delete to free matrix capacity.


Note The Delete button requires a Superuser security level.


Stop. You have completed this procedure.

NTP-D78 Create a Monitor Circuit

Purpose

This procedure creates a monitor circuit that monitors traffic on primary, bidirectional circuits on E1 or STM-1 cards.

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 17-47 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.


Note 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, or VC for the monitored circuit.


Note In Figure 9-1, the monitor circuit destination is Port 2 on the STM-1 card.


Step 10 Click Next.

Step 11 In the Circuit Routing Preferences area, review the monitor circuit information. If you want the monitor circuit routed on a MS-SPRing protection channel, click Protection Channel Access.

Step 12 Click Finish.

Step 13 From the File menu in the Edit Circuit window, click Close. The new monitor circuit appears on the Circuits tab.

Figure 9-1 shows an example of a monitor circuit. At Node 1, a VC4 is dropped from Port 1 of an STM-1 card. To monitor the VC4 traffic, test equipment is plugged into Port 2 of the STM-1 card and a monitor circuit to Port 2 is provisioned in CTC. Circuit monitors are one-way. The monitor circuit in Figure 9-1 is used to monitor VC4 traffic received by Port 1 of the STM-1 card.

Stop. You have completed this procedure.


NTP-D79 Create a J1 or J2 Path Trace

Purpose

This procedure creates a repeated, fixed-length string of characters used to monitor changes to circuit traffic.

Tools/Equipment

ONS 15454 SDH cards capable of transmitting and/or receiving path trace must be installed. See Table 19-3 on page 19-47 for a list of J1 path trace cards. See Table 20-31 on page 20-66 for a list of J2 path trace cards.

Prerequisite Procedures

J1 path trace can be provisioned on VC3 and VC4 circuits. J2 path trace can be provisioned on VC12 circuits. See Chapter 6, "Create Circuits and Low-Order Tunnels," for circuit creation procedures.

Note There are two types of J1 bytes, high-order (HO-J1) and low-order (LO-J1). The electrical cards support LO-J1 (VC3). The optical cards support HO-J1 (VC4) and cannot monitor the LO-J1 byte. In addition, the E1-42 card supports HO-J1 when the card is provisioned as an HO circuit endpoint.



Note J1 path trace is available for VC3 and VC4 circuits. In ONS 15454 SDH Software R3.4 and earlier, you can set the VC3 J1 transmit string on E3 and DS3i-N-12 cards, but VC3 is not monitored by STM-N cards. J2 path trace is available for VC12 circuits.



Step 1 Complete the "DLP-D60 Log into CTC" task on page 17-47 at a node on the network where you will create the path trace. If you are already logged in, continue with Step 2.

Step 2 Complete the following tasks as needed:

As needed, complete the "DLP-D264 Provision a J1 Path Trace on Circuit Source and Destination Ports" task on page 19-46.

As needed, complete the "DLP-D137 Provision a J1 Path Trace on STM-N Ports" task on page 18-15.
