Windows Media Player
Streaming a conference with Windows Media Player in multiple windows or tabs on the same browser will
crash the browser. This is a known issue with Windows Media Player. If you need to stream more than one
conference simultaneously, use a different player such as QuickTime or Real Player.

conference simultaneously, use a different player such as QuickTime or Real Player.
In addition, Windows Media Player 11 can display streams incorrectly when used as an embedded player
with browsers other than Internet Explorer. This is a known incompatibility. In some cases, setting the video
size of the main streaming video window (the Video size field in the Streaming page) to Large will correct the
problem. To work around this issue, you can use QuickTime or RealPlayer instead of WMP, or use Internet
Explorer instead of your normal browser.

The MCU does not support 64-bit versions of Windows Media Player. To work around this limitation, use a
32-bit version of Windows Media Player.

Streaming to QuickTime 7 causes problems with some browsers
Streaming to an embedded QuickTime player using the QuickTime 7.0 plus later option for the Player format
on the MCU can cause certain browsers to crash or remain in the 'negotiating' state indefinitely. Affected
browsers include: IE6; Firefox 1.5 (Mac and PC); Safari 2.0.3 and earlier, and Camino. IE7 and Safari 2.0.4
do not appear to be affected by this. Using the QuickTime 6.5 plus later option for the Player format on the
MCU will allow streaming to QuickTime using any browser that supports a QuickTime plug-in.

Clustering limitations
Cisco TelePresence MCU Conference Director will only work with the master blade in a cluster.
If you are using Cisco Telepresence Management Server Version 12.6 or earlier to schedule conferences on
clustered blades, only add the master blade to TMS. Do not add slave blades to TMS and remove from TMS
any blade that you subsequently configure as a slave blade: you will need to reconfigure any scheduled
conferences that were previously configured on slave blades as new conferences running on the master
blade.

Uploading and downloading large files while heavily loaded
We recommend that you do not upload or download large files from the MCU while it is hosting active calls.
Files such as CDRs, audit logs and code images should be transferred when there are few or no calls on the
MCU.

Raw IPv6 addresses in Firefox 4.0 and later
It is not possible to access an MCU HTTPS web interface in Mozilla Firefox Version 4.0 using a raw IPv6
address. It is possible with IPv4 addresses and in earlier versions of Firefox, or if a hostname is used instead
of the raw IPv6 address. This issue is being tracked by Mozilla as bug 633001.

Automatic link-local IPv6 assignment on disabled interface
When you enable IPv6 on any of the device's Ethernet ports (
Network > Port A
or
Network > Port B
), the
device automatically assigns a link-local IPv6 address to each Ethernet port, even if the port is disabled. An
IP address that is assigned to a disabled Ethernet port may not be apparent on the web interface.
