Configuring Audio Video Bridging The following sections provide information about various aspects relating to audio and video bridging networks. Restrictions for Audio Video Bridging Networks, on page 1 Introduction to Audio Video Bridging Networks, on page 1 How to Configure the Audio Video Bridging Network, on page 6 Monitoring the Audio Video Bridging Network, on page 15 Examples of Audio Video Bridging Configurations and Monitoring, on page 17 Feature History for Audio Video Bridging, on page 38 Restrictions for Audio Video Bridging Networks • AVB is not supported on stacked systems. • AVB is not supported on EtherChannel interfaces. • AVB is supported only on STP-enabled network.
• The maximum number of MSRP streams supported is 200 in one device. • The C9300-48HX, C9300-48TX, C9300-24HX, C9300X-48HXN, C9300-24UX, C9300-48UXM, C9300-24UXB, and C9300-48UN switch models do not support gPTP at 100Mbps speed. Introduction to Audio Video Bridging Networks Information about Audio Video Bridging Audio and video equipment deployments have traditionally been analog single-purpose point-to-point one-way links. Migration to digital transmission also continued to retain the point-to-point one-way links architecture. The dedicated connection model resulted in a mass of cabling in professional and consumer applications, which was hard to manage and operate.
In order to accelerate the adoption to Ethernet based audio/video deployments in an interoperable way IEEE came up with the IEEE Audio Video Bridging standards - IEEE 802.1BA. This defines a mechanism where endpoints and the network will function as a whole to enable high quality A/V streaming across consumer applications to professional audio-video over an Ethernet infrastructure.
