Today, the broadcast industry uses a serial digital interface (SDI) router and SDI cables to transport video and audio traffic. The SDI cables can carry only a single unidirectional signal. As a result, a large number of cables, frequently stretched over long distances, is required, making it difficult and time-consuming to expand or change an SDI-based infrastructure.
Cisco’s IP fabric for media solution helps transition from an SDI router to an IP-based infrastructure. In an IP-based infrastructure, a single cable has the capacity to carry multiple bidirectional traffic flows and can support different flow sizes without requiring changes to the physical infrastructure. The IP fabric for media solution consists of a scalable spine and leaf architecture built using Cisco Nexus 9000 Series switches in conjunction with the Cisco non-blocking multicast (NBM) algorithm (an intelligent traffic management algorithm) and the Cisco DCNM Media Controller. The solution provides a highly reliable (zero drop multicast), highly visible, highly secure, and highly available network.
Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 7.0(3)I4(5) supports a spine-leaf topology that consists of multiple spine and leaf switches.
Table 2 lists the hardware that the Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 7.0(3)I4(5) supports. For additional information about the supported hardware, see the Hardware Installation Guide for your Cisco Nexus 9000 Series device.

Bug ID |
Description |
Enabling, disabling, and reenabling the nbm mode controller command does not restore the sender flow. Workaround: Stop the traffic and wait for the s,g timeout for the sender flows and then start again, or reload this node again using the nbm mode controller command. |
Cisco’s IP fabric for media solution 7.0(3)I4(2) release was designed for a single-spine, non-controller deployment. If you want to migrate from a single-spine, non-controller deployment to a multiple-spine, controller deployment, you will need to upgrade your switches to Cisco NX-OS Release 7.0(3)I4(5) and completely change the configuration as the switches need to be reconfigured in NBM controller mode. You will also need to modify the TCAM allocation. Because most deployments are built using redundant networks, with minimal or no disruption to production, each side of the fabric can be upgraded one after the other.
To perform a software upgrade or downgrade, follow the installation instructions in the Cisco Nexus 9000 Series NX-OS Software Upgrade and Downgrade Guide and refer to the Cisco Nexus 9000 Series NX-OS Release Notes, Release 7.0(3)I4(5) for specific upgrade and downgrade information related to this release.
