Note The HTTPS feature and Session-Based Encryption feature are released as general availability (GA) features in Release 3.2. For more information on these features, see the Release Notes for 3.0.0 (http://www.cisco.com/en/US/docs/video/cds/cda/is/3_0/release_notes/CDS_RelNotes3_0_0.html).


New Features in Release 3.2.1-b20

VDS-IS 3.2.1-b20 introduces a feature to protect small cache files from eviction. When the cache file size is smaller than the configured size, this feature prevents files from being evicted for a period regardless of priority. The period is to be set on the Content Management screen. To configure this feature navigate to Devices>General Setting>Content Management.


Note The max protection file number is 300000 for small files protection.


New Features in Release 3.2.1-b15

Support for CDE250-2S5 hardware configuration.

VDS-IS 3.2.1-b15 introduces support for CDE250-2S5 hardware configuration. The CDE250-2S5 can be used at entry level Internet Streamer and its configurations include a 1.5 TB SSD cache storage, 12 x 160 GB drives.

The CDE250 ships with the following components installed:

2 Quad Core Intel Xeon (Westmere) CPUs @ 2.4GHz

4 Onboard Gigabit Ethernet NIC

2 x Dual 10GE NIC ports in slots 2 and 6, and 10GE Ports support Copper and Fiber SFP Media Modules

2 Hot-swappable power supplies

1 x 8-GB CF + IDE adapter physically attached as IDE primary master

3 external SAS disk controllers located into slots 1, 3 and 4

1 internal MegaRAID SAS disk controller located in slot 5


Note External drives and bay expanders ship separately and are not installed in the CDEs. Bay expanders with mounted disks have stickers labeling the drive numbers from 1 to 12. For more information about Cisco CDE hardware, see http://www.cisco.com/en/US/docs/video/cds/cde/cde205_220_420/installation/guide/cde205_220_420_hig.html.

Upgrading to Release 3.2.1

Release 3.2.1 supports upgrades from Release 2.5.9, Release 2.5.11, Release 2.6.x, Release 3.0.x, and Release 3.1.x.


Note When upgrading from Release 2.x to Release 3.x, and the streaming interface IP address is set as the management IP address on the SE, the rpc_httpd process fails to start because of a port 443 binding issue. Before upgrading to Release 3.x, either check the Use SE's primary IP address for management communication check box on the Device Activation page for the SE, or use a separate IP addresses for the streaming traffic and the management traffic (primary interface).



Note If your CDS software is older than Release 2.6.1 and you have CDE205 and CDE220 platforms in your system, you must check that the partition size (specifically, disk 00/02), on each CDE205 and CDE220 in your system is larger than 0.5 GB. To check the partition size, enter the show disks detail command. If the disk00/02 partition is not larger than 0.5 GB, you must upgrade the CDE to Release 2.6.1 before upgrading to Release 3.x.


If your CDS is running an older release than Release 2.5.9, you need to upgrade to Release 2.5.9 or 2.5.11 before upgrading to Release 3.2.1

When upgrading from Release 2.5.9 or 2.5.11, all content is erased. For Service Engines, this means that prefetched metadata and content need to be redistributed from upstream SEs after the upgrade, and that cached content is not preserved. Additionally, Flash Media Streaming service rules must be converted from device-based service rules to the Service Rule XML file. For more information on upgrading from Release 2.5.9 and 2.5.11, see the Cisco Internet Streamer CDS 2.6 Software Upgrade Guide (http://www.cisco.com/en/US/docs/video/cds/cda/is/2_6/upgrade_guide/upgrade.html).

We strongly recommend that you upgrade your CDS network devices in the following order:

1. Multicast sender Service Engines

2. Multicast receiver Service Engines

3. Edge Service Engines

4. Middle-tier Service Engines

5. Content Acquirers

6. Service Routers

7. Standby CDSMs (Upgrade before primary when using the GUI only.)

8. Primary CDSM


Note When using the CDSM GUI to upgrade from Release 2.5.9, 2.5.11, or 2.6.1 to Release 3.2.1, after you upgrade the standby CDSM, if you switch roles of the standby CDSM and primary CDSM to maintain an active CDSM, the old primary CDSM is now the standby CDSM, and the old standby CDSM is now the primary CDSM. At this point, you must use the CLI to upgrade the new standby CDSM. The primary CDSM GUI cannot upgrade the standby CDSM.

Alternatively, if you do not switch roles of the standby CDSM and primary CDSM, you can use the CDSM GUI to upgrade the primary CDSM. The primary CDSM loses connectivity with the CDS devices for a short time during the upgrade, but this is not service affecting.

When using the CDSM GUI to upgrade from Release 2.6.3 and later releases to Release 3.2.1, after you upgrade the standby CDSM, if you switch roles of the standby CDSM and primary CDSM to maintain an active CDSM at all times, the new primary CDSM GUI can be used to upgrade the new standby CDSM.


For more information on the upgrade procedure, see the Cisco Internet Streamer CDS 3.2 Software Configuration Guide.

After the upgrade procedure starts, do not make any configuration changes until all the devices have been upgraded.

Installation Prerequisite for UCS 220/240 with C240M3.1.5.1c.0 Firmware

The new CIMC firmware (C240M3.1.5.1c.0, Build Date: 01/31/2013) uses the names of the first 3 devices for virtual drives. As a result, any system with 24 drives will be mapped from /dev/sdd to /dev/sdaa, with disk0 pointing to /dev/sdaa. The installation fails because disk0 is by default the system disk, where GRUB is installed.

Follow these steps before the installation of the image on UCS 220/240:

On the "Cisco CDS-IS Installer" screen, when prompted for choice, enter option 1 to configure hardware.

Select option 1 again to "Configure Disks".

Select option 3 to "Configure Disk Management Policy".

Select option 2 "Do not use RAID".

Select option 2 to choose "disk01" to be used as system disk.

Confirm that you wish to "Change the boot device as well" by entering Y.

Confirm that you wish to "Include a CDNFS partition on SYSTEM disk(s)" by entering Y.

Message on screen says "RAID policy updated".

Select option 3 to "Return to Previous menu".

Select option 6 to "Save settings and Exit".

Select option 4 to "Return to Previous menu".

Now proceed to "Install all Software". For more information refer, Cisco Internet Streamer CDS 3.0--3.2 Software Installation Guide for non-CDEs.

Downgrading from Release 3.2.1


Note When downgrading from Release 3.2.1 to Release 2.5.x, make sure the Coverage Zone file is less than 7500 lines. If the Coverage Zone file is 7500 lines or greater, reduce the number of lines before downgrading to Release 2.5.x. This is not an issue when downgrading to Release 2.6.x.


For software downgrades from Release 3.2.1 on systems with primary and standby CDSMs, you need to do the following:


Step 1 If you are using the CDSM GUI, downgrade the standby CDSM first, followed by the primary CDSM.

If you are using the CLI, downgrade the primary CDSM first, followed by the standby CDSM.

Step 2 After downgrading the primary and standby CDSMs, using the CLI, log in to each CDSM and run the following commands:

To downgrade from 3.2.1 to 2.5.9 or 2.5.11

cms database downgrade script downgrade/Downgrade3_1_2_b20_to_3_1_2_b19
cms database downgrade script downgrade/Downgrade3_1_1_to_3_1
cms database downgrade script downgrade/Downgrade3_1_to_3_0
cms database downgrade script downgrade/Downgrade3_0_to_2_6
cms database downgrade
cms enable

Then, consult the "Downgrading the Internet Streamer CDS Software" chapter in the Cisco Internet Streamer CDS 2.6 Software Upgrade Guide for downgrading from Release 2.6.x to Release 2.5.9 or 2.5.11.

To downgrade from 3.2.1 to 2.6.x

cms database downgrade script downgrade/Downgrade3_1_2_b20_to_3_1_2_b19
cms database downgrade script downgrade/Downgrade3_1_1_to_3_1
cms database downgrade script downgrade/Downgrade3_1_to_3_0
cms database downgrade script downgrade/Downgrade3_0_to_2_6
cms database downgrade

cms enable

After downgrade from 3.2.1 to 2.6.1, If SE does not come up in operational status in SR, restart the Service router and the operational state will be updated.

To downgrade from 3.2.1 to 3.1.0

cms database downgrade script downgrade/Downgrade3_1_2_b20_to_3_1_2_b19
cms database downgrade script downgrade/Downgrade3_1_1_to_3_1
cms database downgrade
cms enable

To downgrade from 3.2.1 to 3.1.1 or 3.1.2.bN(N<20)

cms database downgrade script downgrade/Downgrade3_1_2_b20_to_3_1_2_b19
cms database downgrade
cms enable

To downgrade from 3.2.1 to 3.1.2.bN(N>=20)

cms database downgrade
cms enable

Downgrade the software on the Service Routers, followed by the Service Engines.
