These release notes describe new features, and open and closed hardware and software caveats for the Cisco TelePresence System Software Release IX 9. The Cisco TelePresence System IX5000 and IX5200 use this software.

A copy of the source code used in this product that is licensed under the General Public License Version 2.0 can be obtained by emailing a request to cts-gpl@cisco.com.

New in Release IX 9.1.1

The following feature is new in this release:

See the Unresolved Caveats in Release IX 9.1.1 for a list of the unresolved caveats for this release.

See the Resolved Caveats in Release IX 9.1.1 for a list of the resolved caveats for this release.

TMS High Mode Support

From IX 9.1.1 onward, TMS can add IX endpoints in high mode as well. The CA signed certificates required by the TMS server which is running on high mode needs to be uploaded as a service certificate in IX web UI. After the uploaded certificate is selected, both the IX web UI and calendaring service will start using the same CA signed certificate for authentication purposes.

New in Release IX 9.1.0

There are no new features in this release. This release provides bug fixes only.


Note

IX Release 9.1.0 first published on Cisco.com on 14-Jun-2019.

The IX 9.1.0(3) release with enhanced security causes connectivity issues between the existing TMS and IX solution. The existing TMS must be updated to match the enhanced security in IX 9.1.0(3). The TMS team is working on CSCvq22807 to address the issues. Therefore, IX 9.1.0(3) is removed from Cisco.com, and is replaced with IX 9.1.0(4) to keep the existing solution intact.

We will release an enhanced security version of IX with TMS upgrade as a solution in the near future.

See the Resolved Caveats in Release IX 9.0.0 for the list of resolved caveats for this release.

Touch 10 User Interface Update

In IX 9.0.0, a new release of Touch software has been added, which contains Touch10 device bug fixes and the user interface changes. With IX 9.0, Touch10 control device for IX series video systems provides a new look and feel experience, in line with other Cisco video systems. The Touch10 user interface screen panels and the icons now look similar to MX and SX Series Endpoint’s Touch device.

Active Control Feature

Active Control allows conference participants to administer a conference on the Cisco Meeting Server using the video system's interfaces.

Each user can see the participant list, change the video layout, disconnect participants, and so on, from the interface.

The following functions have been added as part of the Active Control feature implementation on IX5000; no other active control functionalities are currently supported.

  • Participant List Display on the Touch Device

  • Handling audio mute and unmute requests from remote

With Active Control enabled, IX gets a participant list from remote that shows all meeting participants and IX pushes this list to display on the Touch device. This list updates dynamically, based on the participant join and drop from meeting.

In a CMS hosted conference with the active control feature enabled, the conference resource can send mute and unmute messages to IX5000 endpoints, based on admin or other participants actions.

When IX5000 gets a MUTE request, the microphones are muted and the microphone LEDs are turned RED. In addition to this, the MUTE icon and the appropriate text are displayed on the main center display. IX users can unmute themselves if they want.

In the case of an UNMUTE request from remote, IX5000 is not unmuted directly. A message shows up on the center display screen to request that the user unmute the audio locally.

New Display Firmware

In IX 9.0.0, new Display Firmware, 51.01.04, has been included with the improvements to address the black screen issues. As per IX Escalation data, unstable power can cause the display to stick in an unknown state, and no video displays on the screen. Display Firmware, 51.01.04, prevents the displays from getting into an unknown state.

Important Notes for IX Software Releases

See the following sections for important notes about IX software releases.

*IMMEDIATE IX SOFTWARE UPGRADE REQUIRED*

FOLLOW ALL STEPS IN THIS SECTION AFTER YOU PHYSICALLY INSTALL YOUR SYSTEM

Your IX system comes preloaded with a downrev version of IX software. You must upgrade your system to the latest version on Cisco.com before you use your system to place and receive calls.

Preinstallation Requirements

Due to some issues with the preloaded software, make the following changes to your system before you load the software (requires signing in to Unified CM and the IX system administration GUI):

  • Make sure that a Certificate Trust List (CTL) is not present on your system and, if present, delete it. To check, after initial system boot, log in to the IX System administration GUI using the IP address (default username and password is admin / cisco), navigate to Configuration > Call Control Manager, and click Delete Certificate Trust List. For more information, see the "Certificates" section of the "Understanding the Fields In the Interface" section of the Administration Guide for Cisco TelePresence Software Release IX 8.

Tip: Some browsers do not allow you to navigate directly to the Configuration page. If you have any problems, click Monitoring, then click Configuration.

After you perform the preceding changes, but before you begin first-time set up, you must download the latest IX software version from Cisco.com and load it to your IX system from this link (cisco.com log in ID required):

https://software.cisco.com/download/navigator.html

Navigate to the IX release software using the path Products > Collaboration Endpoints > TelePresence IX 5000 Series and select the model for your system. On the Download Software page, select the latest release.

While the system software is upgrading for the first time, you might see the following symptoms, which do not indicate a problem:

  • The progress bar might freeze.

  • The system reboots several times.

  • The screen changes from the blue progress screen, with progress bar, to a blank screen.

Do not perform any corrective actions, and wait for the upgrade to complete.

For general information about adding the software to Unified CM and upgrading the software, see the "Configuring Cisco Unified Communications Manager for Your Cisco TelePresence System" section of the IX5000 and IX5200 First-Time Setup document.

Required Pre- and Post-Installation Steps

To make sure that Touch 10 devices initialize properly, you must perform all steps as described in the "Preventing Touch 10 Bootup Issues" section of the IX5000 and IX5200 First-Time Setup document. Failing to perform these steps could cause your Touch 10 devices to become inoperable.


Note

Before you start the first-time setup, you must disable Proximity for the Touch 10 devices. For more information, see CSCvk42541 in Unresolved Caveats in Release IX 9.0.0.


Unified CM Device Pack Requirements

Make sure that your Unified CM software has the minimum required device pack version.

  • The minimum device pack version for 9.1.2 is 9.1(2.13063)

  • The minimum device pack version for 10.5 is 10.5(1.12016).

Older versions for these Unified CM releases do not have the Cisco TelePresence IX5000 as a device type.

For device package compatibility, see the Cisco Unified Communications Manager Device Package Compatibility Matrix: https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/compat/matrix/CMDP_BK_CCBDA741_00_cucm-device-package-compatibility-matrix.html

Tip: For an IX5200, configure the device type as Cisco TelePresence IX5000 (18 seats).

Proximity-Based Content Sharing Support


Note

The Proximity Share From Clients enable option is not available on CUCM versions prior to 10.5.2.


The following table shows the Cisco Unified CM device pack version required to enable or disable "Proximity Share To Clients" on the Cisco Unified CM.

Unified CM Version

Device Pack Version

12.0.1

12.0.1.22022

11.5.1

11.5.1.16083

11.0.1

11.0.1.25097

10.5.2

10.5.2.18155

9.1

Not available

Required Pre- and Post-First Time Setup (FTS) Steps

Make sure that proximity service is disabled on the IX5000 system before the start of FTS. This prevents the connection of proximity-app devices (laptop or mobile) to IX5000 systems during FTS. Proximity service can be enabled or disabled from Touch 10 devices.

To disable, click the settings icon on the Touch 10 device, located at top left corner, and then change Intelligent Proximity mode to off.

After the completion of FTS, proximity service has to be enabled to use proximity feature for content sharing.

System Behavior During Times of Network Congestion

Anything that degrades network performance can affect Cisco TelePresence voice and video quality and, in some cases, can cause a call to drop. Sources of network degradation can include, but are not limited to, the following activities:

  • Administrative tasks such as an internal port scan or security scan

  • Attacks that occur on your network, such as a denial-of-service attack

To reduce or eliminate any adverse effects to a TelePresence conference, schedule any administrative network tasks during a time when the Cisco TelePresence system is not being used, or exclude TelePresence systems from the testing.

Jitter and Packet Loss Statistics Include IX System Statistics

When you view network jitter statistics on the Touch 10, and network jitter and latency statistics in the system logs, note that these numbers include jitter and latency statistics that are internal to your IX system as well as for your overall network.

Downgrade the Software

You cannot downgrade the IX software version using standard downgrade procedures. You must switch from the current software version on the active partition of the IX system to the earlier software version stored on the inactive partition. The following limitations apply:

  • Using the Swap Loads operation in the Unified CM Device Defaults Configuration to downgrade is not supported.

  • You can upgrade the software version for all IX systems in a Unified CM cluster. However, you must downgrade the software version on each IX system separately. While upgrades are performed in Unified CM, downgrades must be performed directly in the IX file system.

  • You can only switch the IX software version to the version stored on the inactive partition on the IX system. Typically, this is the version immediately prior to the release version being used.

To switch your IX system to the down rev version stored on the inactive partition, perform the following steps.

Procedure


Step 1

Use SSH to start a CLI session on your IX system.

Step 2

Enter the show version command to verify the IX software versions that are stored in the active and inactive partitions.

Example

The example below shows the IX software versions where IX 8.1.1 is stored in the active partition and IX 8.1.0.1 is stored in the inactive partition.

admin: show version

Active: IX 8.1.1(59) P3 2016-03-19 13:01:17
Inactive: IX 8.1.0.1(11) P3 2015-12-16 13:50:22
loads file information
Active (cmterm-IX8-1-1-59R-K9.P3)
IX: IX.8-1-159R-K9.P3.deb.SPA
Touch: CTSDEV10-442-11-0-1KKPL-112.pkg
Inactive: (cmterm-IX.8-1-0-1-11R-K9.P3)
IX: IX.8-1-0-1-11R-K9.P3.deb.SPA
Touch: CTSDEV10-442-11-0-1KKPL-112.pkg

To downgrade, you need to switch the active and inactive partitions so that the older software version is in the active partition.

Step 3

In Unified CM, enter Device > Phone.

Step 4

Search for Device Type and specify the search criteria as "contains" and specify "IX5000" in the search text. Click Find.

Step 5

Click on the Device Name for the IX system.

Step 6

In the Device Information area, change the Phone Load Name to a dummy name. This prevents the IX system from booting, allowing access to change the software version. Click Save.

You must change the Phone Load Name to a dummy name. Note that removing the Phone Load Name and leaving the field name blank will not work.

Step 7

Reenter the CLI session on your IX system.

Step 8

Enter the utils system switch-version command to switch the inactive partition to the active partition.

The IX software version stored in the inactive partition now becomes the version used for the active phone load.

Example

admin: utils system switch-version

Switching to Inactive Image: IX 8.1.0.1(11) P3 2015-12-16 13:50:22
Are you sure you want to switch the system, this will cause a system reset
Enter “yes” to switch and restart or any other key to abort
continue:
Step 9

Enter the show version command again to verify that the downgraded software version is now in the active partition.

Example

The example below shows the IX software versions where IX 8.1.0.1 is now stored in the active partition and IX 8.1.1 is stored in the inactive partition.

admin: show version

Active: IX 8.1.0.1(11) P3 2015-12-16 13:50:22
Inactive: IX 8.1.1(59) P3 2016-03-19 13:01:17
loads file information
Active (cmterm-IX.8-1-0-1-11R-K9.P3)
IX: IX.8-1-0-1-11R-K9.P3.deb.SPA
Touch: CTSDEV10-442-11-0-1KKPL-112.pkg
Inactive: (cmterm-IX8-1-1-59R-K9.P3)
IX: IX.8-1-159R-K9.P3.deb.SPA
Touch: CTSDEV10-442-11-0-1KKPL-112.pkg
Step 10

Exit the CLI session and reenter the Unified CM interface.

Step 11

(Optional) Return to the Device Information Area for the IX system. Change the Phone Load Name from the dummy name to the IX software version now stored in the active partition on the system. Click Save.

Step 12

Repeat this procedure for each IX system that you want to downgrade.


Exceptions with Other Cisco Devices

Presentation Sharing While in a Multipoint Call

During multipoint calls when using TelePresence Server and TelePresence Conductor, resource optimization can cause presentation sharing to downgrade from 1080p resolution at 30 fps (1080p 30) to 1080 5 fps. This condition can cause video from a whiteboard presentation to look jerky.

In addition, TelePresence Conductor must be configured to enable 1080p30 (1920 tokens on conductor) (CSCur22200).

Exceptions with Third-Party Endpoints

No exceptions found.

Important Notes for IX System Hardware

See the following sections for important notes about IX system hardware.

Table Furniture Care

The IX system table surface is made with top-grade natural wood. The table surface is not scratch resistant. Please treat the table surface with care as delicate furniture. When retracting or returning the presentation cable, the three-headed adapter should not be pulled across the table top because this can scratch the surface.


Note

Once the table has been delivered and accepted, it is the customer’s responsibility to take care and maintain the look of the table surface. Cisco will NOT be responsible for damages due to negligence or improper care.


Supported IX Auxiliary Devices

This section contains auxiliary devices that can be used with the IX systems.

The Cisco TelePresence system works best when suitable devices are attached using good quality cables and connectors. Cisco does not supply the cable that connects auxiliary devices to the codec.

Displays

This section describes the display choices you have with your Cisco TelePresence System.

Qualified Cisco Displays

The following displays are qualified for use with Cisco TelePresence System running IX software:

  • 42-inch display, part number CTS-5K-DISP42 (Spare is CTS-5K-DISP42=)


    Note

    The release notes previously reported that the 42-inch display, part number CTS-MON-42-WW is a qualified Cisco display. This part number is not a qualified Cisco display for the IX system.


  • 55-inch display, part number CTS-MON-55-WW


    Note

    HDMI-to-HDMI cables are not supported for display connections to the IX codec. You must use the HDMI-to-DVI cable for the displays (DVI on the display side). Some versions of the 55-inch display do not include a DVI input; use the included DVI-to-HDMI adapter to connect cables to the HDMI input on the display.


Cisco has supported two different 55-inch displays from the following vendors:

  • Sampo

    The Sampo display is currently available.

  • Samsung LH55MECPGGC/ZA

    The Samsung display is no longer available.

If using the Samsung display, before use, turn off all on-screen display (OSD) capability (see Turn Off On-Screen Display). This prevents the display from showing messages after you stop sharing a presentation. If using the Sampo display, OSD capability is disabled by default.

Turn Off On-Screen Display

To turn off OSD on the Samsung display, complete the following steps using the remote control that comes with the system, or use the joystick control on the back of the display.

Procedure

Step 1

Turn the display on.

Step 2

Press MENU on the remote, or press the center of the joystick and move the joystick to select the menu option (the choice on the left), to bring up the menu for the display.

Step 3

Using the up and down arrows, navigate to System in the menu panel.

Step 4

Press Enter if using a remote, or press the center of the joystick if using the joystick on the display, to select the System choice.

Step 5

Using the up and down arrows, navigate to General and press either Enter on the remote, or the center of the joystick on the display.

This choice does not appear initially. Scroll down to see it.

Step 6

Navigate to OSD Display and press Enter or the center of the joystick.

Step 7

Set all three OSD choices (Source OSD, No Signal OSD, and MDC OSD) to Off (the default is On) to disable OSD messages.

Step 8

Press EXIT on the remote, or move the joystick to the previous menu choices, until the menu no longer displays.


Use of Nonqualified Displays with Your IX System

Cisco does not support nonqualified displays with your IX system. If you are using a nonqualified display with the IX system, unforeseen issues and adverse failures can result. When troubleshooting, Cisco and Cisco TAC will request that nonqualified auxiliary displays be disconnected to isolate system-related issues.

Document Cameras

The following WolfVision document cameras (object cameras) have been tested for use with IX systems:

  • Model: EYE-12, Version: V1.30b

  • Model: VZ-C6, Version: V1.35a

  • Model: VZ-C12-3, Version: V1.25c


Note

You cannot control the document camera using the Touch 10 interface. Use the remote control that is provided with the document/object camera.


LCD Displays and Viewing Angle

Since the IX5000 uses LCD displays instead of the plasma displays used in earlier CTS/TX immersive systems, the display quality may be reduced from some viewing angles. Viewing angles from the side are typically affected. If there is poor lighting in the room and the user is looking across the displays of the IX, the colors can change across screens. This is a normal property of LCD displays.

Hot Swapping of IX Components Not Supported

Hot swapping of IX system components is not supported. Before swapping out components, you must shut the system down, then restart it after the new components are installed.

Systems Cannot be Connected to a Router

Be sure that you connect your TelePresence system to a switch; this device cannot be directly connected to a router.

The router is not capable of creating Virtual Local Area Network (VLAN), which is required in the network design for the Cisco Voice and Video Solution. Please check the Cisco Video and TelePresence Architecture Design Guide as your reference:

https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/uc_system/design/guides/videodg/vidguide/infrastr.html

CSCvu43116

Symptom

On April 29, 2020, the Salt Open Core team notified their community regarding the following two CVE-IDs:

CVE-2020-11651: Authentication Bypass Vulnerability

CVE-2020-11652: Directory Traversal Vulnerability

Cisco TelePresence IX5000 Series, Cisco Modeling Labs Corporate Edition (CML) and Cisco Virtual Internet Routing Lab Personal Edition (VIRL-PE) incorporate a version of SaltStack that is running the salt-master service that is affected by these vulnerabilities.

Cisco has released software updates that address these vulnerabilities. There is a workaround that addresses these vulnerabilities.

This advisory is available at the following link:

https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-salt-2vx545AG

Conditions

Salt services are enabled by default on IX5000 Series endpoints.

Workaround

From Root either of the following commands will show the service/process:

"service --status-all | grep salt"

"ps -aux | grep salt"

Only the salt-master service needs to be stopped using the following:

"service salt-master stop"


Note

This service will be re-enabled upon reboot, so the salt-master service will need to be stopped again after any reboot of the Host CPU.


Workaround has been provided to stop salt-master service on IX5000 system. With uploading modified IX system script file all salt-stack services (salt-minion, salt-syndic, salt-master) will be stopped during reboot itself.

Check with IX Escalation team for workaround.

Note for CSCuw56092, CSCve10940, CSCve80443, and CSCvh45762

Extensive research confirms these four bugs (CSCve80443, CSCvh45762, CSCve10940, and CSCuw56092) are associated with AC power instabilities at the IX5x00 deployment sites. Field data demonstrates that unstable power can result in one or more of the associated IX5x00 "bug signatures" that are similar and connected to one another. Since we cannot recreate these incidents at will in our development labs, we are unable to root-cause and resolve these issues.

Field activities have demonstrated that IX5x00 incidents can be reduced dramatically with following mitigations:

  1. The installation of an uninterruptible power supply (“UPS”)

  2. A weekly reboot of the IX5x00 endpoint.

CSCvi26599

Symptom

IX does not display Merge Failed error on TMS Scheduled calls

Conditions

Audio add-in traverses SIP trunk to another CUCM cluster and goes out MGCP GW.

  1. One IX 5000 shares content locally.
  2. TMS Scheduled conference auto connects both IX 5000's - Conference name is Cisco Testing
  3. Two way A/V established, IX sees presentation from 8.2.3 IX.
  4. Either IX 5000 dials audio add-in locally, dials external audio participant (cell phone) and hits Merge.
  5. Merge succeeds.
  6. Two conferences are seen via CMM - the adhoc conference (named Conference) and the original space conference (named Cisco Testing) and the two are cascaded.
  7. After merge, TIP seems to fail, and content will also no longer be shared (assumed due to lack of BFCP between the two cascaded conferences).

Workaround

  • Have audio participants connect directly to meeting.

  • If ad hoc calls are not desired on IX, set Multipoint Mode to Use Endpoint.

  • Use rendezvous or dial-in meetings—behavior only occurs when TMS schedules a meeting on CMS.

Symptom

A vulnerability in the web UI of Cisco TelePresence IX5000 Series Software could allow an unauthenticated, remote attacker to conduct a cross-frame scripting (XFS) attack against a user of the web UI of the affected software.

The vulnerability is due to insufficient protections for HTML inline frames (iframes) by the web UI of the affected software. An attacker could exploit this vulnerability by persuading a user of the affected UI to navigate to an attacker-controlled web page that contains a malicious HTML iframe. A successful exploit could allow the attacker to conduct click-jacking or other client-side browser attacks on the affected system.

Conditions

A device running an affected version of software.
