Protocols and Endpoints

In a Dual Video Queue approach, what role does the CS4 class serve for Cisco video devices?

  • A Desktop video traffic needs strict priority queuing marked with CS4 class
  • B Create a simpler provisioning with one CBWFQ for desktop and immersive video traffic
  • C Enforce a strict priority queueing for both desktop and immersive video traffic
  • D Immersive video traffic is marked with CS4 and placed in a CBWFQ separate from desktop video
Explanation

CS4 (DSCP 32) identifies immersive TelePresence video so it can be placed in a CBWFQ separate from desktop video traffic. This preserves distinct bandwidth treatment for immersive and desktop video; strict-priority queuing is used for latency-sensitive voice rather than video. Cisco’s collaboration guidance identifies CS4 as the legacy DSCP for TelePresence calls and distinguishes this traffic from desktop video.
