Obtaining Documentation and Submitting a Service Request
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 solution uses Cisco Nexus 9000 Series switches in conjunction with the Cisco non-blocking multicast (NBM) algorithm (an intelligent traffic management algorithm) and with or without the Cisco DCNM Media Controller to provide 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)F2(1) supports two deployment methods:
· A spine-leaf topology with the DCNM Media Controller—A flexible architecture for large-scale deployments typically seen in an IP studio
· A single modular switch without the DCNM Media Controller—A simple deployment method for environments such as outside broadcasting (OB) vans
Table 2 lists the hardware that the Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 7.0(3)F2(1) supports. For additional information about the supported hardware, see the Hardware Installation Guide for your Cisco Nexus 9000 Series device.

Role in Topology |
N9K-9508 with the following line cards: · N9K-X9636C-R · N9K-X9636Q-R |
Cisco Nexus 9508 8-slot switch N9K-X9636C-R: 36-port 100-Gigabit Ethernet QSFP28 line card supporting 1 x 100 and 1 x 40 Gigabit Ethernet N9K-X9636Q-R: 36-port 40-Gigabit Ethernet QSFP+ line card supporting 1 x 40 Gigabit Ethernet |
Spine in spine-leaf topology with DCNM Media Controller or Single modular switch without DCNM Media Controller Note: When the Cisco Nexus 9508 switch is used as a spine switch in a spine-leaf topology, the Cisco Nexus 9236C, 9272Q, 92160YC-X, 93108TC-EX, and 93180YC-EX switches can be used as leaf switches. |
Cisco DCNM Release 10.2.1 or later is required to access the Media Controller.
Leaf switches must run Cisco NX-OS 7.0(3)I6(1) or a later release when used with spine switches that are running Cisco NX-OS Release 7.0(3)F2(1) or a later release.
