IP Fabric for Media
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 10.3(1)F 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.
New Hardware Features
The following new hardware are introduced in Cisco NX-OS Release 10.3(1)F for deployment in IP Fabric for Media solution:
● N9K-C9808 16-RU modular switch with slots for up to 8 line cards in addition to two supervisors, 8 fabric modules, 4 fan trays, and up to 9 power supplies.
● N9K-X9836DM-A a 36-port 400-Gigabit Ethernet QSFP-DD line card for Cisco Nexus 9800 family switches.
● N9K-C9808-FM-A a Fabric module for Nexus 9808 chassis.

Open Issues
There are no open issues in Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 10.3(1)F.
There are no resolved issues in Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 10.3(1)F.
NBM static OIF can include an SVI; however, an IGMP snooping entry must be manually created to force the traffic out of the Layer 2 physical interface.
To prevent packet drops for NBM flows, configure 5% more bandwidth than the traffic being sent.
Follow these steps to upgrade from a Cisco NX-OS 7.x or 9.x release to Cisco NX-OS Release 10.3(1)F in an IP fabric for media deployment.
Note: For Cisco Nexus 9504 and 9508 switches with -R line cards, you must upgrade from Cisco NX-OS Release 7.0(3)F3(4) to a 10.x release.
1. Shut down the endpoint-facing ports on the switches.
2. Disable NBM (using the no feature nbm command).
3. Disable the ip pim pre-build-spt force command on the spine switches in your fabric.
4. Disable PIM passive mode (using the no ip pim passive command).
5. Upgrade the switch software from 7.x or 9.x to 10.3(x).
6. For Cisco Nexus 9504 and 9508 switches with -R line cards, configure these TCAM carving commands in the following order and then reload the switch:
hardware access-list tcam region redirect_v6 0
hardware access-list tcam region ing-nbm 2048
7. Upgrade DCNM.
8. Configure PIM and MSDP, if applicable.
9. Enable NBM (using the feature nbm command).
10. Configure NBM policies using the CLI or DCNM. (See the Cisco Nexus 9000 Series IP Fabric for Media Solution Guide, Release 10.3(x).)
11. If you're not using DCNM, disable IGMP static OIF and create an NBM flow definition to establish a flow.
12. Re-enable all ports facing the endpoints.
13. On configuring "feature nbm", DEFAULT VRF will not come in any PMN mode (pim-active/passive). You must configure it explicitly using command "nbm mode pim-active"/"nbm mode pim-passive" under Default VRF.
14. On configuring NBM non-default VRF using "nbm vrf <foo>", NON-DEFAULT VRF will not come in any PMN mode (pim-active/passive). You must configure it explicitly using command "nbm mode pim-active"/"nbm mode pim-passive" under Non-Default VRF.
