Release Notes for Cisco Transport Planner, Release 10.5.2

Software Features

The new software features of Cisco Transport Planner, Release 10.5.2 are listed in Table 2 .

Performing Automatic Software Updates in CTP

This section explains how to perform an automatic software update.

Step 1 When CTP is launched, it checks for the latest software update automatically. If available, the following dialog box appears: Online Update Available, Would you like to Update CTP? Click Yes.

Step 2 The Software Update Dialog box appears listing the applicable software updates. Select the required software update and click Apply.

Step 3 The Update Successful message appears. Click OK.

Note The Update dialog box appears every time CTP is launched until the software update is applied.

Performing Manual Software Updates in CTP

Contact the Cisco Sales/Account team to get the software update files.

This section explains how to perform a manual software update.

Step 1 In the CTP Help menu, go to Help > Check updates. The update CTP dialog box appears.

Step 2 Click Browse.

Step 3 Select the .upz update file and click OK.

Step 4 The Software Update Dialog box appears listing the applicable software updates. Select the required software update and click Apply.

Step 5 The Update Successful message appears. Click OK.

Step 6 Delete the cache and restart CTP.

Performing Software Update Rollback

CTP allows rollback of software updates. A single rollback moves the CTP software to the previous state (prior to the software update). For example, if there are two updates applied one by one—Update 1 and Update 2, after the first rollback, CTP removes Update 2 and retains Update 1. Further rollback(s) are needed if multiple updates are present.

This section explains how to perform a rollback.

Step 1 Press R while CTP is launching. The CTP launch is interrupted to perform a software rollback.

Step 2 Click Yes to confirm software rollback. The rollback successful dialog box appears.

Note ● Delete CTP Cache before and after applying update. Procedures about deleting cache are mentioned in the CTP Operations Guide. Take a backup of the required files (User preferences, CTP Design Files (.mpz), NeUpdate File, Alien Files, and so on) before deleting CTP cache.

• Automatic Update can be performed only when you are connected to the Cisco network. If you are not on a Cisco network, try to connect to Cisco VPN first. Otherwise, the software update file should be manually provided by a Cisco representative and manually updated.
• Changes caused by the software update is applicable even if the CTP Cache is deleted after the update. To remove an update, follow the rollback procedure mentioned in the previous section.
• Multiple rollbacks are not supported in this release. Re-install CTP if required.
• In the Java Control Panel, set the Java security to medium and mention the CTP installation directory in the Exception Site List (if there are issues with the rollback). If the screen is unresponsive, end CTP process and restart CTP.
• For MAC, force quit the process and restart CTP (if there are issues with the rollback).
• After uninstallation, delete all the files under the directory where CTP is installed manually.

– Default location on Windows OS: C:\Program Files\Cisco\CTP10.5.2.

– Default location on Mac OS: Applications/CiscoCTP10.5.2

Operating System Requirements

CTP Release 10.5.2 runs on systems with the following operating systems:

• Microsoft Windows 2000 Professional
• Microsoft Windows XP Professional
• Microsoft Vista Business
• Microsoft Windows 7 Professional
• Linux
• Apple MacBook (up to Yosemite).

Note Microsoft Windows 7 Professional is the preferred operating system for CTP Release 10.5.2.

Supported Java Runtime Environment

CTP Release 10.5.2 requires that you install one of the following Java Runtime Environment versions:

• Windows 7 OS with Java 1.7
• Mac OS Yosemite with Java 1.7

– Use the following command to set the Java path to 1.7:
export JAVA_HOME=`/usr/libexec/java_home -v '1.7*'`

Hardware Requirements

CTP Release 10.5.2 runs on systems with the following hardware configurations:

Customizing Memory Usage for JVM

CTP Release 10.5.2 allows you to customize the maximum amount of memory to be used by the Java Virtual Machine (JVM). The default value of 1024 MB is appropriate for use with the recommended hardware (1GB of RAM).

For hardware using less physical memory, it is recommended that you reduce the maximum amount of memory to be used by the JVM. This reduction prevents the system from using system virtual memory, which results in poorer system performance.

If you reduce the amount of memory dedicated to JVM, Cisco Transport Planner may generate an Out of Memory error in the case of a complex design, typically when designing an any-to-any traffic design with a large number of nodes. In such cases, it is recommended that you increase the memory size.

Allowing JVM to use too much memory compared to the available RAM can instead result in very low system performances due to the use of virtual memory. The following table lists the recommended settings:

.

To change the maximum amount of memory to be used by the JVM, you need to edit the Startup.properties file, which is available in the directory where you saved the ctp.jar file during installation. Replace the default value (1024 MB) with the appropriate one from the Suggested JVM Memory column of the preceding table. Save the file and restart the Cisco Transport Planner for the changes to take effect.

Note The suggested memory values are for a system with fairly less load. If there are many processes running on your system, changing to the suggested memory value may not launch CTP. In such cases, reduce the JVM memory appropriately (you may reduce the memory in granularity of 100 MB) by editing the Startup.properties file.
