Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Description

August 06, 2021

  Cisco NX-OS Release 9.3(8) became available.

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 9.3(8) 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.

Supported Device Hardware

Table 2 lists the hardware that the Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 9.3(8) supports. For additional information about the supported hardware, see the Hardware Installation Guide for your Cisco Nexus 9000 Series device.

Resolved Issues

Bug ID

Description

CSCvx73439

Headline: N9000 leak egress interface bandwidth with frequent igmp joins/leaves received mili-seconds apart.

Symptoms: End node cannot pull additional mcast stream.

Workarounds: Reload device or disable bandwidth management.

CSCvx92926

Headline: On Igmp leave,MSDP SA cache entry is deleted,this causing delay in traffic convergence.

Symptoms: None

Workarounds: None

Limitations

When using ASM (IGMPv2), the bandwidth is reserved between the receiver leaf switch and the spine switch even when the sender is local to the receiver leaf switch.

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.

Upgrade Instructions

Follow these steps to upgrade from a Cisco NX-OS 7.x or 9.x release to Cisco NX-OS Release 9.3(8) 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 9.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 9.3(8).

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 10.1(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.
