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 solution supports the following types of deployments:
● 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(2)F for deployment in IP Fabric for Media solution:
● N9408 - Centralized modular switches of 4 RU high, and eight expansion slots to support 64 ports of 400G or 128 ports of 200G.

The following features are enhanced for Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 10.3(2)F.
| Feature |
Description |
| NBM support on sub-interfaces |
NBM subinterface type is now supported in NBM pim-active and pim-passive modes on Layer 3 sub-interfaces. Support is provided on Cisco Nexus 9200, 9300, 9408 and 9800 platform switches, and Cisco Nexus 9504 and 9508 switches with -R line cards. |
| Multicast NAT support on sub-interfaces for IPFM flows |
Multicast NAT support is now supported on all host and fabric ports for NBM pim-active and pim-passive modes on Layer 3 sub-interfaces. |
| Flexible NBM modes with Multi-tenancy VRF |
Beginning with Cisco NX-OS Release 10.3(2)F, the pim-active and pim-passive modes can coexist on the same switch. |
| NAT Enhancement |
Beginning with Cisco NX-OS Release 10.3(2)F, egress service reflection (egress multicast NAT, and multicast to unicast NAT) supports Post-NAT Source IP to be IP Address of an egress interface. This enhancement is supported for regular multicast, and for NBM. |
Open Issues
There are no open issues in Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 10.3(2)F.
There are no resolved issues in Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 10.3(2)F.
For example: If the parent port is part of NBM VRF which is in PIM active mode, its subinterfaces must also be in the VRF (can be different VRF context) with the same PIM active mode.
