Cisco Transport Controller Operation
This chapter describes Cisco Transport Controller (CTC), the Cisco ONS 15600 software interface that is stored on the Timing and Shelf Controller (TSC) card and downloaded to your workstation each time you log into the ONS 15600. For CTC setup and login information, refer to the Cisco ONS 15600 Procedure Guide.
Chapter topics include:

CTC Software Delivery Methods
•
4.1 CTC Software Delivery Methods
Use CTC to provision and administer the ONS 15600. CTC is a Java application that is installed in two locations:
•
•
CTC is stored on the TSC card and is downloaded to your workstation each time you log into an ONS 15600.
4.1.1 CTC Software Installed on the TSC Card
CTC software is preloaded on the ONS 15600 TSC cards; therefore, you do not need to install software on the TSC. To upgrade to a newer CTC software version, use the Cisco ONS 15600 Software Upgrade Guide.
You can view the software versions that are installed on one ONS 15600 by clicking the Maintenance > Software tabs in node view. Click the tabs in network view to display the software versions installed on all the network nodes.
4.1.2 CTC Software Installed on the PC or UNIX Workstation
When you connect to the ONS 15600, the TSC card automatically downloads the CTC software to your computer, where it is automatically installed if you have the correct Java Runtime Environment (JRE). The automatic download/installation process ensures that your computer is running the same CTC software version as the TSC you are accessing. The CTC software files are stored in the temporary directory designated by your computer's operating system. You can use the Delete CTC Cache button to remove files stored in the temporary directory. If the files are deleted, they are downloaded the next time you connect to an ONS 15600. Downloading the Java archive (JAR) files for CTC takes several minutes depending on the bandwidth of the connection between your workstation and the ONS 15600. For example, JAR files downloaded from a modem or a SONET data communications channel (SDCC) network link requires more time than JAR files downloaded over a LAN connection.
4.2 CTC Installation Overview
To connect to an ONS 15600 using CTC, enter the ONS 15600 IP address in the URL field of a web browser, such as Netscape Navigator or Microsoft Internet Explorer. After connecting to an ONS 15600, the following events occur automatically:
Note
1.
2.
3.
4.
Each ONS 15600 can handle up to 16 simultaneous CTC sessions. CTC performance might vary depending upon the volume of activity in each session.
Note
4.3 PC and UNIX Workstation Requirements
To use CTC with an ONS 15600, your computer must have a web browser with the correct JRE installed and a modified java.policy file. The correct JRE, Java plug-in, and modified java.policy file for the CTC software release are included on the Cisco ONS 15600 software CD.
Note
To manage more than 50 nodes, Cisco recommends using Cisco Transport Manager (CTM). If you do use CTC to manage more than 50 nodes, you can improve performance by adjusting the heap size; see the "General Troubleshooting" chapter of the Cisco ONS 15600 Troubleshooting Guide. You can also create login node groups; see the "Connect the PC and Log Into the GUI" chapter of the Cisco ONS 15600 Procedure Guide.Table 4-1 provides the minimum requirements for PCs and UNIX workstations.
4.4 CTC Login
After you have installed CTC, you can log in to a node using your browser. To log in, you must type the node IP address in the URL window. The CTC Login window appears (Figure 4-1).
Figure 4-1 Login Window
The CTC Login window provides the following options to accelerate the login process.
•
•
These options are useful if you want to log in to a node to perform a single task, such as placing a card in or out of service, and do not want to wait while CTC discovers DCC connections and circuits.
4.4.1 Legal Disclaimer
The CTC Login window currently displays the following warning message (Figure 4-1): "Warning: This system is restricted to authorized users for business purpose. Unauthorized access is a violation of the law. This service can be monitored for administrative and security reasons. By proceeding, you consent to this monitoring."
The ONS 15600 allows a user with Superuser privileges to modify the default login warning message and save it to a node using the Provisioning > Security > Legal Disclaimer > HTML tab (Figure 4-2). The login warning message field allows up to 250 characters of text (1600 characters total, including HTML markup).
Figure 4-2 Legal Disclaimer Tab
4.4.2 Login Node Group
Login node groups display nodes that have only an IP connection. After you are logged into CTC, you can create a login node group from the Edit > Preferences menu. Login groups appear in the Additional Nodes list (Figure 4-1) on the Login window.
For example, if you logged into Node 1, you would see Node 2 and Node 3 because they have DCC connectivity to Node 1. You would not see Nodes 4, 5, and 6 because DCC connections do not exist. To view all six nodes at once, you create a login node group with the IP addresses of Nodes 1, 4, 5, and 6. Those nodes, and all nodes optically connected to them, appear when you select the login group from the Additional Nodes list on the Login window the next time you log in.
4.5 CTC Window
The CTC window appears after you log into an ONS 15600. The CTC node view is the first view that appears after you log into an ONS 15600 (Figure 4-3). The login node is the first node displayed, and it is the "home view" for the session (accessed by choosing View > Go To Home View).
The CTC window includes a menu bar, a toolbar, and a top and bottom pane. The top pane displays status information about the selected objects and a graphic of the current view. The bottom pane displays tabs and subtabs, which you use to view ONS 15600 information and perform ONS 15600 provisioning and maintenance. From the default node view window you can display the other two ONS 15600 views: network and card.
Figure 4-3 CTC Window Elements in the Node View (Default Login View)
4.5.1 Node View
Node view allows you to view and manage one ONS 15600 node (Figure 4-3). The status area shows the node name; number of Critical (CR), Major (MJ), and Minor (MN) alarms; IP address; session boot date and time; name of the current logged-in user; and user security level.
4.5.1.1 CTC Card Colors
The graphic area of the CTC window depicts the ONS 15600 shelf assembly. The colors of the cards in the graphic reflect the real-time status of the physical card, slot, and port. Table 4-2 describes the node view card colors.
Port color in both card and node view indicates the port service state. Table 4-3 lists the port colors and their service states. For more information about port service states, see Appendix B, "Administrative and Service States."
Table 4-3 Node View Card Port Colors and Service States
Blue
OOS-MA,LPBK
(Out-of-Service and Management, Loopback) Port is in a loopback state. On the card in node view, a line between ports indicates that the port is in terminal or facility loopback (see Figure 4-4 and Figure 4-5). Traffic is carried and alarm reporting is suppressed. 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.
Blue
OOS-MA,MT
(Out-of-Service and Management, Maintenance) Port is out-of-service for maintenance. Traffic is carried and loopbacks are allowed. Alarm reporting is suppressed. 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. Use OOS-MA,MT for testing or to suppress alarms temporarily. Change the state to IS-NR, OOS-MA,DSBLD, or OOS-AU,AINS when testing is complete.
Gray
OOS-MA,DSBLD
(Out-of-Service and Management, Disabled) The port is out-of-service and unable to carry traffic. Loopbacks are not allowed in this service state.
Green
IS-NR
(In-Service and Normal) The port is fully operational and performing as provisioned. The port transmits a signal and displays alarms; loopbacks are not allowed.
Violet
OOS-AU,AINS
(Out-of-Service and Autonomous, Automatic In-Service) The port is out-of-service, but traffic is carried. Alarm reporting is suppressed. The node monitors the ports for an error-free signal. After an error-free signal is detected, the port stays in OOS-AU,AINS state for the duration of the soak period. After the soak period ends, the port service state changes to IS-NR.
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. The AINS port will automatically transition to IS-NR when a signal is received for the length of time provisioned in the soak field.

4.5.2 Network View
Network view allows you to view and manage ONS 15600s, ONS 15454s, and ONS 15327s that have DCC connections to the node that you logged into and any login node groups you have selected (Figure 4-6).
Figure 4-6 Network Displayed in CTC Network View
Note
To access network view, choose View > Go To Network View or click the up arrow in the CTC toolbar.
The graphic area displays a background image with colored node icons. A Superuser can set up the logical network view feature, which enables each user to see the same network view.
The node icon colors indicate the node status (Table 4-5). Lines show DCC connections between the nodes. Selecting a node or span in the graphic area displays information about the node and span in the status area.
Table 4-6 lists the tabs and subtabs available in the network view.
4.5.3 Card View
The card view provides information about individual ONS 15600 cards. Use this window to perform card-specific maintenance and provisioning (Figure 4-7). A graphic showing the ports on the card is shown in the graphic area. The status area displays the node name, slot, number of alarms, card type, equipment type, and the card status (active or standby), card service state if the card is present, and port service state (described in Table 4-3). The information that appears and the actions you can perform depend on the card. For more information about card service states, see Appendix B, "Administrative and Service States."
Note
Figure 4-7 CTC Card View Showing an OC-192 Card
Use the card view tabs and subtabs, shown in Table 4-7, to provision and manage the ONS 15600. The subtabs, fields, and information displayed under each tab depend on the card type selected.
4.6 CTC Card Reset
You can reset the ONS 15600 cards by using the hard-reset or soft-reset commands in CTC, or by physically reseating a card (card pull). From the node view, select a card and right-click to open a menu with the hard-reset and soft-reset commands. Soft resets do not impact traffic, however hard resets are service-affecting. A card must be in the Out-of-Service and Management, Maintenenace (OOS-MA,MT) service state before you can perform a hard reset.
A soft reset on the TSC reboots the TSC and reloads the operating system and the application software. You can apply a CTC soft reset to either an active or standby TSC without affecting traffic. A CTC hard reset temporarily removes power from the TSC and clears all buffer memory.You should only perform a hard reset (or a card pull) on a standby TSC. If you need to perform a CTC hard reset or card pull on an active TSC, put the TSC into standby mode first by performing a soft reset.
A soft reset on an optical card with an active port in a 1+1 protection group will result in a loss of all DCC traffic terminated or tunneled on the active port for the duration of the reset time. A soft reset of an optical card with a standby port in a 1+1 protection group will not affect DCC traffic. A CTC hard reset of an optical card causes a switch to the protect card.
4.7 TSC Card Database
Each TSC card hosts a separate database; therefore, the protect card's database is available if the database on the working TSC fails. After a database change, there might be a 30-second interval before the TSC starts writing the data to the Flash drive. If you reset the active TSC immediately after a database change, the change could be lost.
You can also store a backup version of the database on the workstation running CTC. This operation should be part of a regular ONS 15600 maintenance program at approximately weekly intervals and should also be completed when preparing an ONS 15600 for a software upgrade or a pending natural disaster, such as a flood.
Note
Note
4.8 Software Load Revert
Before you upgrade to Software Release 5.0, you must create a database backup. If you later need to restore the original working software load from the protect software load, CTC displays a prompt requesting the location of the backup. Any provisioning performed with Software R5.0 will be lost when the Software R1.1.x backup is restored.
