Media and QoS

When a single video queue is used for QoS, which DSCP value is recommended for Jabber video endpoints?

  • A AF32
  • B AF43
  • C EF
  • D AF42

In Cisco’s single-video-queue QoS design with DSCP-based WRED, Jabber video is classified as opportunistic video and marked AF42. This gives it a higher drop precedence than prioritized AF41 video during congestion, while EF is reserved for audio traffic.
