Manage Circuits


This chapter explains how to manage Cisco ONS 15454 electrical, optical (OC-N), Ethernet, and virtual concatenated (VCAT) circuits. It also explains how to manage optical channel network connections provisioned in dense wavelength division multiplexing (DWDM) networks.


Note The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.

Step 1 Navigate to the appropriate CTC view:

To view circuits for an entire network, from the View menu, choose Go to Network View.

To view circuits that originate, terminate, or pass through a specific node, from the View menu, choose Go to Other Node, then choose the node you want to search and click OK.

To view circuits that originate, terminate, or pass through a specific card, in node view, double-click the card containing the circuits you want to view.


Note In node or card view, you can change the scope of the circuits that appear by choosing Card (in card view), Node, or Network from the Scope drop-down menu in the bottom right corner of the Circuits window.


Step 2 Click the Circuits tab. The Circuits tab shows the following information:

Name—Name of the circuit. The circuit name can be manually assigned or automatically generated.

Type—Circuit types are: STS (STS circuit), VT (VT circuit), VTT (VT tunnel), VAP (VT aggregation point), OCHNC (DWDM optical channel network connection), STS-v (STS VCAT circuit), or VT-v (VT VCAT circuit).

Size—Circuit size. VT circuits are 1.5. STS circuit sizes are 1, 3c, 6c, 9c, 12c, 24c, 48c, 192c. OCHNC sizes are Equipped not specific, Multi-rate, 2.5 Gbps No FEC (forward error correction), 2.5 Gbps FEC, 10 Gbps No FEC, and 10 Gbps FEC. VCAT circuits are STS-1-2v, STS-3c-2v, or STS-12c-2v.

OCHNC Wlen—For OCHNCs, the wavelength provisioned for the optical channel network connection. See Table 5-6 for a list of channels and wavelengths.

Direction—The circuit direction, either two-way or one-way.

OCHNC Dir—For OCHNCs, the direction of the optical channel network connection, either east to west or west to west.

Protection—The type of circuit protection. See Table 11-1 for a list of protection types.

Table 11-1 Circuit Protection Types 

Protection Type
Description

N/A

Circuit protection is not applicable.

2F BLSR

The circuit is protected by a two-fiber bidirectional line switched ring (BLSR).

4F BLSR

The circuit is protected by a four-fiber BLSR.

BLSR

The circuit is protected by a both a two-fiber and a four-fiber BLSR.

Path Protection

The circuit is protected by a path protection.

Path Protection-DRI

The circuit is protected by a path protection dual ring interconnection.

1+1

The circuit is protected by a 1+1 protection group.

Y-Cable

The circuit is protected by a transponder or muxponder card Y-cable protection group.

Splitter

The circuit is protected by the protect transponder (TXPP_MR_2.5G) splitter protection.

Protected

The circuit is protected by diverse SONET topologies, for example, a BLSR and a path protection, or a path protection and 1+1.

2F-PCA

The circuit is routed on a protection channel access (PCA) path on a two-fiber BLSR. PCA circuits are unprotected.

4F-PCA

The circuit is routed on a protection channel access path on a four-fiber BLSR. PCA circuits are unprotected.

PCA

The circuit is routed on a protection channel access path on both two-fiber and four-fiber BLSRs. PCA circuits are unprotected.

Unprot (black)

The circuit is not protected.

Unprot (red)

A circuit created as a fully-protected circuit is no longer protected due to a system change, such as removal of a BLSR or 1+1 protection group.

Unknown

Circuit protection types appear in the Protection column only when all circuit components are known, that is, when the circuit status is ACTIVE or UPGRADABLE. If the circuit is in some other status, the protection type is "unknown."


Status—The circuit status. Table 11-2 lists the circuit statuses that can appear.

Table 11-2 Cisco ONS 15454 Circuit Status 

Status
Definition/Activity

CREATING

CTC is creating a circuit.

ACTIVE

CTC created a circuit. All components are in place and a complete path exists from the circuit source to the circuit destination.

DELETING

CTC is deleting a circuit.

INCOMPLETE

A CTC-created circuit is missing a cross-connect or network span, a complete path from source to destination(s) does not exist, or an Alarm Interface Panel (AIP) change occurred on one of the circuit nodes and the circuit is in need of repair. (AIPs store the node MAC address.)

In CTC, circuits are represented using cross-connects and network spans. If a network span is missing from a circuit, the circuit status is INCOMPLETE. However, an INCOMPLETE status does not necessarily mean a circuit traffic failure has occurred, because traffic may flow on a protect path.

Network spans are in one of two states: up or down. On CTC circuit and network maps, up spans are shown as green lines, and down spans are shown as gray lines. If a failure occurs on a network span during a CTC session, the span remains on the network map but its color changes to gray to indicate the span is down. If you restart your CTC session while the failure is active, the new CTC session cannot discover the span and its span line will not appear on the network map.

Subsequently, circuits routed on a network span that goes down will appear as ACTIVE during the current CTC session, but they will appear as INCOMPLETE to users who log in after the span failure. The INCOMPLETE status does not appear for OCHNC circuit types.

UPGRADABLE

A TL1-created circuit or a TL1-like CTC-created circuit is complete and has upgradable cross-connects. A complete path from source to destination(s) exists. You can upgrade the circuit using the "A417 Upgrade TL1 Cross-Connects to CTC Circuits" procedure. This status does not appear for OCHNC circuit types.

INCOMPLETE_UPGRADABLE

A TL1-created circuit or a TL1-like CTC-created circuit with upgradable cross-connects is missing a cross-connect, and a complete path from source to destination(s) does not exist. The circuit cannot be upgraded until missing cross-connects are in place. This status does not appear for OCHNC circuit types.

NOT_UPGRADABLE

A TL1-created circuit or a TL1-like CTC-created circuit is complete but has at least one non-upgradable cross-connect. UPSR_HEAD, UPSR_EN, UPSR_DC, and UPSR_DROP cross-connects are not upgradable, so all unidirectional path protection circuits created with TL1 are not upgradable. This status does not appear for OCHNC circuit types.

INCOMPLETE_NOT_UPGRADABLE

A TL1-created circuit or a TL1-like CTC-created circuit with one or more non-upgradable cross-connects is missing a connection or circuit span (network link); a complete path from source to destination(s) does not exist. This status does not appear for OCHNC circuit types.


Source—The circuit source in the format: node/slot/port "port name"/STS/VT. (The port name will appear in quotes.) Node and slot will always appear; port "port name"/STS/VT might appear, depending on the source card, circuit type, and whether a name is assigned to the port. If the circuit size is a concatenated size (3c, 6c, 12c, etc.), STSs used in the circuit will be indicated by an ellipsis, for example, "S7..9," (STSs 7, 8, and 9) or S10..12 (STS 10, 11, and 12).

Destination—The circuit destination in same format (node/slot/port "port name"/STS/VT) as the circuit source.

# of VLANS—The number of VLANS used by an Ethernet circuit.

# of Spans—The number of inter-node links that constitute the circuit. Right-clicking the column shows a shortcut menu from which you can choose to show or hide circuit span detail.

State—The circuit state Table 11-3 lists the circuit states that may appear.

Table 11-3 Cisco ONS 15454 Circuit States 

State
Definition

IS

In service; able to carry traffic.

OOS

Out of service; unable to carry traffic. This status does not appear for OCHNC circuit types.

OOS-AINS

Out of service, auto in service; alarm reporting is suppressed, but traffic is carried and loopbacks are allowed. Raised fault conditions, whether or not their alarms are reported, can be retrieved on the CTC Conditions tab or by using the TL1 RTRV-COND command. VT circuits in OOS-AINS generally switch to IS when source and destination ports are IS, OOS-AINS, or OOS-MT regardless of whether a physical signal is present. STS circuits in OOS-AINS switch to IS when a signal is received. This status does not appear for OCHNC circuit types.

OOS-MT

Out of service, maintenance; alarm reporting is suppressed, but traffic is carried and loopbacks are allowed. Raised fault conditions, whether or not their alarms are reported, can be retrieved on the CTC Conditions tab or by using the TL1 RTRV-COND command. This status does not appear for OCHNC circuit types.

Step 1 From the View menu on the node view, choose Go to Network View. If you are already in network view, continue with Step 2.

Step 2 Right-click the green line containing the circuits you want to view and choose one of the following:

Circuits—To view BLSR, path protection, 1+1, VCAT, DWDM optical channel network connections, or unprotected circuits on the span.

PCA Circuits—To view circuits routed on a BLSR protected channel. (This option does not appear if the span you right-clicked is not a BLSR span.)

In the Circuits on Span dialog box, you can view the following information about the circuits that traverse the span. The information that appears depends on the circuit type.

For OC-N, VCAT, DS-1, and DS-3 circuits provisioned on the span, the following information appears:

STS—Displays STSs used by the circuits.

VT—Displays VTs used by the circuits (VT circuits).

UPSR—(path protection span only) If checked, path protection circuits are on the span.

Circuit—Displays the circuit name.

Switch State—(path protection span only) Displays the switch state of the circuit, that is, whether any span switches are active. For path protection spans, switch types include: CLEAR (no spans are switched), MANUAL (a manual switch is active), FORCE (a force switch is active), and LOCKOUT OF PROTECTION (a span lockout is active).


Note You can perform other procedures from the Circuits on Span dialog box. If the span is in a path protection, you can switch the span traffic. See "DLP-A197 Initiate a Path Protection Force Switch" task for instructions. If you want to edit a circuit on the span, double-click the circuit.

Step 1 Complete the "DLP-A60 Log into CTC" task 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:

STS-1 Matrix—(XC, XCVT, XC10G) Provides the percent of the cross-connect card STS-1 path resources that are in use. 288 STS-1 paths are available for XC or XCVT cards; 1152 STS-1 paths are available for XC10G cards.

VT Matrix Ports—(XCVT and XC10G) Provides the percent of the cross-connect card VT matrix ports that are in use. Each port is one STS in size, and each can transport 28 VT1.5s. 24 VT matrix ports are available for the XCVT and XV10G cards.

VT Matrix—(XCVT and XC10G) Provides the percent of the VT matrix resources that are in use. 672 are available, which is the number of VT matrix ports (24) multiplied by the number of VT1.5s in an STS (28).

Step 4 In the VT Matrix Port Detail section, you can view details of the VT Matrix Port usage:

Drop—Identifies the source slot, port, and STS.

Tunnel Name—VT tunnels use VT matrix ports on the tunnel source and destination nodes (VT tunnels do not use matrix resources on pass-through nodes). If the port is used by a VT tunnel, the tunnel name will appear here.

% Used—Shows the percent of the matrix port that are in use. Each matrix port can carry 28 VT1.5s, so for example, if one STS carries seven VT1.5 circuits, the matrix port will be 25% used.

Usage—Shows the port usage. For example, if one STS carries seven VT1.5 circuits, the matrix port will show that 7 of 28 are in use.

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

Click the Refresh button to see an updated XC Resources view. For example, if other users create circuits while you view the XC Resources tab, click Refresh to see the effects those circuits have on the VT matrix usage.

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


Note The Delete button requires a Superuser security level.



Note VT tunnels may appear as STSs with 0% capacity used. These cannot be deleted.

a. On the Circuit Path Trace window, enable the path trace expected string by choosing Auto or Manual from the Path Trace Mode drop-down menu:

Auto—The first string received from the source port is automatically provisioned as the current expected string. An alarm is raised when a string that differs from the baseline is received.

Manual—The string entered in the Current Expected String field is the baseline. An alarm is raised when a string that differs from the Current Expected String is received.

b. If you set the Path Trace Mode field to Manual, enter the string that the circuit destination should receive from the circuit source in the New Expected String field. If you set Path Trace Mode to Auto, skip this step.

c. Click the Disable AIS and RDI if TIM-P is detected check box if you want to suppress the alarm indication signal (AIS) and RDI when the STS Path Trace Identifier Mismatch Path (TIM-P) alarm appears. Refer to the Cisco ONS 15454 Troubleshooting Guide for descriptions of alarms and conditions.

d. (Check box visibility depends on card selection) Click the Disable AIS on C2 Mis-Match check box if you want to suppress the Alarm Indication Signal when a C2 mismatch occurs.

e. Click Apply, then click Close.


Note It is not necessary to set the format (16 or 64 bytes) for the circuit destination expected string; the path trace process automatically determines the format.


Step 10 Provision the circuit source expected string:

a. In the Edit Circuit window (with Show Detailed Map chosen, see Figure 11-4) right-click the circuit source port and choose Edit Path Trace from the shortcut menu.

b. In the Circuit Path Trace window, enable the path trace expected string by choosing Auto or Manual from the Path Trace Mode drop-down menu:

Auto—Uses the first string received from the port at the other path trace end as the baseline string. An alarm is raised when a string that differs from the baseline is received.

Manual—Uses the Current Expected String field as the baseline string. An alarm is raised when a string that differs from the Current Expected String is received.

c. If you set the Path Trace Mode field to Manual, enter the string that the circuit source should receive from the circuit destination in the New Expected String field. If you set Path Trace Mode to Auto, skip this step.

d. Click the Disable AIS and RDI if TIM-P is detected check box if you want to suppress the alarm indication signal (AIS) and RDI when the STS Path Trace Identifier Mismatch Path (TIM-P) alarm appears. Refer to the Cisco ONS 15454 Troubleshooting Guide for descriptions of alarms and conditions.

e. (Check box visibility depends on card selection) Click the Disable AIS on C2 Mis-Match check box if you want to suppress the Alarm Indication Signal when a C2 mismatch occurs.

f. Click Apply.


Note It is not necessary to set the format (16 or 64 bytes) for the circuit source expected string; the path trace process automatically determines the format.


Step 11 After you set up the path trace, the received string appears in the Received field on the path trace setup window. The following options are available:

Click Hex Mode to display path trace in hexadecimal format. The button name changes to ASCII Mode. Click it to return the path trace to ASCII format.

Click the Reset button to reread values from the port.

Step 5 In the detailed circuit map right-click the circuit OC-N port (the square on the left or right of the source node icon) and choose Edit Path Trace from the shortcut menu.


Note The OC-N port must be on a receive-only card listed in Table 11-4. If not, the Edit Path Trace menu item will not appear.


Step 6 In the Circuit Path Trace window, enable the path trace expected string by choosing Auto or Manual from the Path Trace Mode drop-down menu:

Auto—Uses the first string received from the port at the other path trace end as the current expected string. An alarm is raised when a string that differs from the baseline is received. For OC-N ports, Auto is recommended because Manual mode requires you to trace the circuit on the Edit Circuit window to determine whether the port is the source or destination path.

Manual—Uses the Current Expected String field as the baseline string. An alarm is raised when a string that differs from the Current Expected String is received.

Step 7 If you set the Path Trace Mode field to Manual, enter the string that the OC-N port should receive in the New Expected String field. To do this, trace the circuit path on the detailed circuit window to determine whether the port is in the circuit source or destination path, then set the New Expected String to the string transmitted by the circuit source or destination. If you set the Path Trace Mode field to Auto, skip this step.
