Network Requirements for CMR Hybrid and Cloud

Where ClearPath is available, less packet loss is always better.

So please keep in mind that the tolerance the WebEx client has for impairments in a meeting has two distinct levels
- one for TCP connections and one for UDP, where UDP ports 9000/9001 are available and open from the WebEx
client to the WebEx site.
Best Practices for Cisco WebEx and Cisco CMR Meetings
●
Ensure WebEx clients are connecting through UDP (vs TCP fallback).
●
Turn off the camera on mobile devices when you’re not active speaker - to remove yourself
from the floor calculation.
●
Turn off the camera on WebEx clients that are experiencing low-bandwidth warnings.
●
Perform a network assessment test particularly for Wi-Fi users to ensure adequate connectivity.
●
Ensure WebEx site settings are set to 15 fps for video, and that HD and 360p video are enabled.
Summary
CMR meetings have special bandwidth requirements and a different performance envelope than meetings using
only Cisco WebEx applications.
Because of the requirements needed to build a common layer between WebEx and telepresence users, we will find
a common floor, which is dynamic in any CMR meeting. This floor effect will be noticed only by telepresence users
when the WebEx user is the active speaker, and vice-versa. When a telepresence user is the active speaker, seen
by other telepresence users, there is no floor effect. The same is true for users communicating through only
WebEx applications.
