These release notes support the Cisco Content Distribution Network (CDN) Software Enterprise Solution Version 2.0.
This release notes document is organized into the following sections:
Cisco CDN Software Enterprise Solution Version 2.0 adds important new features to the product. Among the software enhancements in Version 2.0 are:
Users and CDN administrators interact with the product using a Web-based graphical interface to the CDM that provides easy access to most CDN functions. The following minimum hardware and software requirements apply to each machine that will be used as a workstation to access the CDM.
For more information on configuring your CDN devices, refer to the Cisco CDN Software Enterprise Solution Configuration Guide.
The following sections are intended to help you upgrade from an earlier version of the CDN software to Version 2.0. If you are setting up the CDN for the first time, refer to the Cisco CDN Software Enterprise Solution Configuration Guide for instructions on "Activating Content Distribution Network Devices."
To determine which version of the CDN software your devices are running, use the System feature of the Content Distribution Manager as follows:
Step 1 Launch your Web browser and enter the IP address or DNS name of your CDM into the address field, for example:
http:// 127.0.0.1/start.html
Step 2 When prompted, log in to the CDM using an administrative username and password.
Step 3 From the Devices menu, click System. The System dialog box appears displaying information on the selected device.
Step 4 Choose the name of the device you are inquiring about from the Device Selector list. Information on the selected device appears in the System dialog box.

ftp://access_code:userid@host.domain/coded
Step 3 Browse the directory tree until you locate the directory containing the CDN software upgrade files, for example:
ftp://userid:password@ftp.cisco.com/cisco/internet/CDN/
|
Note Guest users will only be able to see images that are located under the /pub directory. |
Step 4 Download the software update to your local machine in binary format.
If you are prompted to open the file or save it to a disk, choose to save the file to a disk. Locate a directory on your hard drive or LAN to temporarily hold the update file and click OK.
|
Note You will later import this file to the CDN, so be sure to place it in a location that makes it easy to retrieve for import later. |
Step 5 Proceed to the "Performing a Manual CDN Software Upgrade" section for instructions on using the upgrade file to upgrade the software on your CDN devices.
To manually upgrade your CDN, you must:
1. Create a channel called MANUAL_UPGRADE that will distribute the updated software.
2. Subscribe any CEs requiring a software update to the MANUAL_UPGRADE channel.
3. Import the software update to the MANUAL_UPGRADE channel.
4. Distribute the software update to all devices marked for upgrade.
After these steps are complete, you can use the Software Update feature to install the software upgrade files to subscribed devices. Refer to the sections below for more details on completing each step.
To create a MANUAL_UPGRADE channel:
Step 1 Launch your Web browser and point it to the CDM.
Step 2 Log on using your administrator logon.
Step 3 From the Channels menu, click Channel Console.
Step 4 Click Add Channel.
Step 5 Click the Edit button next to the channel name Channel #.
|
Note "Channel #" is the default channel name. If you have added other channels and
have not renamed them, the channel that you added will be named "Channel #" (# being the next incremental number). |
Step 6 In the Name field, change the name of the channel to MANUAL_UPGRADE. The channel must use this name (and letter case, as well) in order for it to function as an upgrade channel.
Step 7 In the Size Limit field, enter a value that will accommodate your upgrade files. For example, entering 100 in the field provided and then clicking the MB button sets the size limit of the MANUAL_UPGRADE channel to 100 MB.
Step 8 Select both the Auto Subscribe and Auto Replicate check boxes.
Step 9 Click Save Changes.
After you have created your upgrade channel, subscribe all the devices requiring a software update to that channel.
Step 1 From the Channels menu, click Subscriber.
Step 2 From the Channel Selector, choose the MANUAL_UPGRADE channel.
Step 3 In the Unsubscribed CEs column, click All to select all of the unsubscribed devices for subscription to the upgrade channel.
Step 4 Click Subscribe. The selected CEs will subscribe to the MANUAL_UPGRADE channel and receive upgrade files after they are imported to the channel.
To import the software update to the MANUAL_UPGRADE channel:
Step 1 From the Channels menu, click Media Importer and follow the instructions for importing the files you downloaded from CCO using the Web Server, PC folders, or FTP option.
Step 2 From the Channels menu, click Import Progress to monitor the progress of your import.
When the import is finished, the import status will be "complete." Because the MANUAL_UPGRADE channel was configured as an auto_replicate channel, the update will automatically be replicated to the devices subscribed to the MANUAL_UPGRADE channel.
|
Note It may take a few minutes for the imported files to replicate to your CEs. |
Step 3 After you import your software upgrade to the MANUAL_UPGRADE channel, see the "Updating Software Using the CDM Software Update Feature" section to complete the upgrade process.
From the Software Update dialog box, you can update the system software. To update the system software:
Step 1 From the Devices menu, choose Software Update. The Software Update dialog box appears. (See Figure 4-4 in the Cisco CDN Software Enterprise Solution User Guide.)
Step 2 Under the Available Version heading, click the appropriate version available for upgrade. If only one upgrade is available, a check box is not displayed. The upgrade is selected automatically.
Step 3 Under the Devices Available for Upgrade heading, select the check box for each available device that you want to upgrade.
Step 4 Click Start Update. The selected devices reboot when the upgrade is finished.
The following sections detail the new features and feature enhancements included in the Cisco CDN Software Enterprise Solution Version 2.0 release.
To facilitate licensing upgrades for the components of the CDN, we have developed a procedure that uses the CDN to make the distribution of license upgrade files seamless and centrally organized. Using a specially designated CDN channel, you can initiate license upgrades for certain CDN components from the CDM to any subscribed CEs.
To use the license distribution feature, you must first do the following:
1. Obtain the license file or files
2. Create a license distribution channel on your CDM.
3. Subscribe any CEs requiring license upgrades to your license distribution channel.
4. Import a license file to your license distribution channel.
5. Replicate the license file to subscribed CEs, automatically initiating the license upgrade process on each CE.
Refer to the sections that follow for instructions on completing each of these steps.
The first step in updating your CDN device licenses is to acquire the license files you need to update your CDN components, for example: RealServer.
Step 1 You may acquire your license files directly from Cisco Systems, or from a third party such as RealNetworks. If you have questions regarding where to acquire the necessary license files, contact your Cisco account representative or refer to the "Obtaining Technical Assistance" section for more information.
Depending on the component you are upgrading, license files may be ASCII or binary format. There is no prescribed format that licenses must use for update using the CDN.
Step 2 Once you have acquired your license files, deposit them in a location from which they can easily be imported to your CDM later.
The next step in updating your licenses is to create a channel through which license files will be distributed.
To create a license distribution channel:
Step 1 From the Channels menu, choose Channel Console.
The Channel Console dialog box appears.
Step 2 Click Add Channel.
A new channel with the default name "Channel#" is added to the Channel Console list, where # is a sequential number assigned to the channel.
Step 3 Click Edit for the newly created channel. Using the options provided, rename your channel accordingly. For example,
License_Distribution_Channel
|
Note Unlike the MANUAL_UPGRADE channel, there are no specific requirements for the name of the license distribution channel. |
A description for the channel is optional.
Step 4 Verify that the Auto Subscribe and Auto Replicate options are not selected. You may be distributing license files to selected CEs at specified times, so you do not want these features enabled.
Step 5 Activate the license distribution feature by selecting the Is License.
Step 6 Click Save Changes.
After you create your license distribution channel, you are ready to begin updating your CDM and CEs with license files. However, you must first prepare the channel to distribute the license files by completing the following tasks:
Refer to the sections that follow for more information on each of these steps.
Devices designated to receive new licenses must be subscribed to the license distribution channel.
To subscribe devices to your license distribution channel, follow the directions for "Subscribing a Content Engine to a Channel" in Chapter 3 of the Cisco CDN Software Enterprise Solution User Guide.
CDN devices have their component licenses updated after having license files replicated to them from a designated license update channel on the CDM. (See the "Creating a License Distribution Channel" section.) To begin this process, import your license file to a designated license update channel.
To import a file to your license update channel:
Step 1 From the Channels menu, click Media Importer and follow the instructions for importing the license file you received to your license update channel using any of the import options listed (Web Server, FTP, or PC files).
Step 2 From the Channels menu, click Import Progress to monitor the progress of your import.
When the import is finished, the import status will be "complete."
Step 3 After you import the license file to the license update channel, see the "Replicating the License to Devices" section to complete the license update process.
After you subscribe all devices for which you wish to update software licenses to your license update channel and import the license file to that channel, you are ready to distribute licenses to your CDN devices.
To initiate a software license update for your subscribed CDN devices:
Step 1 From the Channels menu, choose Media Editor.
The Media Editor dialog box appears.
Step 2 Make sure that the designated license distribution channel name is displayed in the drop-down list on the left side of the dialog box. If it is not, click to expand the list and select the license distribution channel.
Step 3 Click the thumbnail image for the license file you imported to the channel to edit its properties.
Fields displaying the media file properties appear.
Step 4 Select the Replicate check box.
Step 5 Click Save Changes.
Clicking Cancel Changes returns all values to their previous settings when you last clicked Save Changes.
The selected file is replicated to all CEs subscribed to the license update channel, initiating the license update process.
|
Note It may take a few minutes for the license file to replicate to the subscribed CEs. |
Once replication is complete, you can begin using your CDN devices in accordance with their updated license information.
Ordinarily, CDN administrators change the admin account password in the same manner as any other account's password. See the "Changing a User Password" in Chapter 2 of the Cisco CDN Software Enterprise Solution User Guide for details on changing passwords for accounts.
However, if you lose track of the password for the admin account and accidentally lock yourself out of the CDM interface, you must manually reset the password for the account before regaining access to the CDM and the Users feature as the default administrator.
Resetting the admin account password restores the factory-configured password to the account. After resetting this password and rebooting the CDM, administrators can again log on using the admin account and configure the password for the account.
|
Note To reset the password for the admin default administrator account, you must have physical access to the CDM device and be able to interface directly with it. Refer to the instructions for connecting a keyboard and terminal or a PC running terminal emulation software to your CDM in the hardware installation guide that came with your CDM hardware. |
Use the following procedure to reset your default administrator password:
Step 1 To reset the default administrator password, you will be required to reboot the CDM machine twice. Ask any users currently logged on to the CDM to exit the system for a short while.
Step 2 If your CDM is running on Cisco hardware, use the console cable kit that came with your hardware to connect the console port of your CDM to the COM port of an ASCII terminal or PC running terminal emulation software. Refer to the Cisco Content Engine 500 Series Hardware Installation Guide or the Cisco Content Networking Hardware Installation Guide for the Seven-Rack Unit Chassis for information on locating the console port, cable and adapters.
If your CDM is not running on Cisco hardware, follow the instructions for attaching a terminal and keyboard directly to the device in the hardware installation guide or configuration guide that came with your hardware.
Step 3 If you connected a PC directly to your CDM, use your preferred terminal emulation software to connect to the CDM by launching a new session and pointing to the IP address of the CDM.
Step 4 Reboot the CDM machine by powering the machine off, and then on again. If your CDM is running on Cisco hardware, refer to the Cisco Content Engine 500 Series Hardware Installation Guide or the Cisco Content Networking Hardware Installation Guide for the Seven-Rack Unit Chassis for information on locating the power button and rebooting your CDM hardware, otherwise refer to the installation or configuration guide that came with the hardware to identify the power button if you are unsure.
Step 5 Wait for the following prompt to appear on your terminal:
LILO Boot:
Step 6 Enter the following command to log on to the CDM as a single user, then press Enter:
LILO Boot# linux single
Step 7 Enter the path for the reset password script, resetpass, as follows at the bash# prompt:
bash# source /sonoma/sys/bin/resetpass
The script executes, resetting the password for the admin account and rebooting the CDM machine. After the CDM completes its reboot, you can log on using the default administrator account by entering the user name, admin, and the factory-configured password.
The following section contains important notes about the Cisco CDN Software Enterprise Solution that are not covered in the standard product documentation.
In instances where CDN devices connect to routers or switches that have been configured to force the use of one data transfer mode (usually 100Mbit/s full duplex), some customers have complained of slow performance and "choppy" playback of media from their CEs.
Decreased playback performance is a result of the CDN device's ethernet card switching from 100Mbit/s full duplex mode to 100 Mbit/s half duplex mode, in which data transmission and reception cannot take place simultaneously.
Most ethernet cards that negotiate duplex settings and port speeds are programmed to avoid conflicts when transmitting data by switching to half duplex mode automatically when they detect that they are connected to a device (for example, a hub) that does not negotiate duplex mode and port speed. Ports that are configured to force the use of one duplex setting and port speed prompt this response.
We recommend making either one of two changes to alleviate the problem of choppy media playback and slow performance resulting from this conflict:
The decision about which device to reconfigure should be made in consultation with your network administrators and in keeping with your own corporate IT policies procedures.
To change the configuration of the router or switch your CDN devices connect to so that it negotiates duplex settings and speeds, refer to the installation, configuration, or command interface documentation that came with the hardware.
If you are unsure of the correct procedure for reconfiguring your hardware, contact the manufacturer's technical support center before proceeding. For questions regarding your CDN software or Cisco hardware, contact Cisco's Technical Assistance Center, TAC. Refer to the "Obtaining Technical Assistance" section for more information on contacting the TAC.
To change the configuration of your CDN device ethernet card so that it does not negotiate duplex setting and port speed, refer to the installation, configuration, or command interface documentation that came with your CDN device hardware.
