Cisco TelePresence MCU 4500 Series

Maximizing performance on MCU 4200, 4500 and MCU MSE 8420 Series products

How can I maximize performance on my MCU 4200, 4500 and MCU MSE 8420 Series products?

This article applies to the following products:

  • Cisco TelePresence MCU 4200 Series
  • Cisco TelePresence MCU 4500 Series
  • Cisco TelePresence MCU MSE 8420 Series

This article applies to the performance of any Cisco TelePresence MCU, however, it is most beneficial to the older models (MCU 4200 Series, MCU 4500 Series and MCU MSE 8420).

Why you should upgrade your MCU?

The most effective way to improve the performance of older MCU models is to upgrade them to the latest software release.

What else can I do to maximize the perfomance for conferencing?

The main purpose of the MCU is to transcode, compose, and distribute video streams between endpoints to provide end users with a high quality conference experience.

The MCU has multiple interfaces and can be administered by people and/or managed by other systems. This can impact the performance of the unit and the quality of the conference experience.

We recommend the following techniques to ensure maximum resources for conferencing:

  • Minimize the number of concurrent web connections, especially at times of high load. Ideally there should be a single device such as Cisco TelePresence Management Suite (TMS) monitoring the unit and monitoring conferences. When not using TMS, minimize the number of users accessing the web interface to avoid overloading the host processor.
  • Disable auto-refresh on the MCU and refrain from refreshing web pages many times over multiple browser windows.
  • Do not have multiple API clients accessing the MCU. For example, if you are using Conference Director, please make sure that the MCU is not accessed by multiple Director instances.
  • Do not turn up any extra logging on the unit unless under the guidance of the TAC team.
  • Do not download or upload large files when the MCU is actively hosting conferences. This includes downloading CDR/Audit etc. logs and back-up files, uploading software images or uploading back-up configuration and so on.
  • Using streaming or ConferenceMe clients may add additional host processor load on the unit, particularly if network conditions are poor. Where possible, use multiple MCUs to distribute these functions to minimize host processor load or use a dedicated streaming server.
  • Read the latest release notes for familiarization of the known limitations and browser support for the software version.
