Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release Notes, Release 10.4(2)F

 

Introduction

This document describes the Cisco IP fabric for media solution, new hardware, software features, upgrade instructions, and caveats for Cisco NX-OS Release 10.4(2)F software for use on Cisco Nexus 9000 Series Switches.

Note:       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.

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, are 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 can 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 Nexus Dashboard Fabric Controller (NDFC) IP for Media Fabric (IPFM) 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 10.4(2)F for deployment in IP Fabric for Media solution:

●     N9K-C93108TC-FX3 – This is a Top of Rack (TOR) L3 switch with total of 54 ports. 48 (Downlink port) supports 100M/1G/10GT and 6 (Uplink port) supports 40G/100G QSFP28.

●     N9K-C93400LD-H1 – This is a 9300 chassis fabric module with total of 52 ports. 48 ports support 50G SFP56 and 4 ports support 400G QSFP-DD ports.

New and Enhanced Features

The following features are enhanced for Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 10.4(2)F:

Open Issues

There are no open issues in Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 10.4(2)F.

Resolved Issues

There are no resolved issues in Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 10.4(2)F.

Upgrade Instructions

Note:       With IFPM, ISSU is not supported, and upgrade will be disruptive.

Note:       The default upgrade process is disruptive. Non-disruptive ISSU is not supported with feature nbm enabled.

Follow these steps to upgrade from a Cisco NX-OS 7.x or 9.x release to Cisco NX-OS Release 10.4(2)F in an IP fabric for media deployment.

Note:       For Cisco Nexus N9K-C9332D-H2R and N9K-C9348GC-FX3 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 10.4(x).

6.     For Cisco Nexus N9K-C9332D-H2R and N9K-C9348GC-FX3 switches with -R line cards, configure these TCAM carving commands in the following order and then reload the switch:

7.     Upgrade NDFC.

8.     Configure PIM and MSDP, if applicable.

9.     Enable NBM (using the feature nbm command).

10.  Configure NBM policies using the CLI or NDFC. (See the Cisco Nexus 9000 Series IP Fabric for Media Solution Guide, Release 10.4(x).)

11.  If you're not using NDFC, 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 the 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.

Limitations

Sub interfaces should be in the same nbm VRF mode as its parent interface. They (Parent port and its sub interfaces) can be in either nbm pim-active or nbm pim-passive mode.

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.
