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, many 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 9.2(1) supports two deployment methods:
· Spine-leaf topology—A single or multi-spine deployment method with variable flow size that allows the NBM fabric to form a multicast flow.
· Single modular switch—An architecture suitable for fixed deployments, with the controller providing features such as flow visibility, security, and monitoring.
Table 2 lists the hardware that the Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 9.2(1) supports. For additional information about the supported hardware, see the Hardware Installation Guide for your Cisco Nexus 9000 Series device.

Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 9.2(1) adds supports for the following hardware:
■ Cisco Nexus 9336C-FX2 and 93240YC-FX2 switches
Note: Cisco Nexus 9504 and 9508 switches with the N9K-X9732C-EX, N9K-X9736C-EX, and N9K-X97160YC-EX line cards are not supported in Cisco NX-OS Release 9.2(1).
This section lists the new software features in Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 9.2(1).
■ Flow bandwidth-Added the ability to configure the flow bandwidth and flow policy bandwidth in Kbps, Mbps, or Gbps and changed the default value to 0.
■ Host policies-Added the ability to configure policies within NBM for senders, local receivers, and external receivers.
■ Multisite-This feature provides a reliable channel of communication between multiple sites, where the sender is in one site and receivers are in another site. You can configure some external (or host-side) interfaces as external links and attach external devices to those links to create a multisite solution. By configuring some interfaces as external links, the solution can perform bandwidth management on those interfaces. Switches running in PIM active mode manage the fabric bandwidth through a distributed bandwidth management algorithm running on all switches.

Follow these steps to upgrade from a Cisco NX-OS 7.x release to Cisco NX-OS Release 9.2(1) in an IP fabric for media deployment.
Note: For Cisco Nexus 9504 and 9508 switches with N9K-X9636C-R and N9K-X9636Q-R line cards, you must upgrade from Cisco NX-OS Release 7.0(3)F3(4) to 9.2(1).
1. Shut down the endpoint-facing ports on the switches.
2. Disable NBM (using the no feature nbm command).
3. Disable PIM passive mode (using the no ip pim passive command).
4. Upgrade the switch software from 7.x to 9.2(1).
5. Configure PIM and MSDP, if applicable.
6. Enable NBM (using the feature nbm command).
7. Configure NBM policies using the CLI or DCNM. (See the Cisco Nexus 9000 Series IP Fabric for Media Solution Guide, Release 9.x.)
8. Re-enable all ports facing the endpoints.
