Cisco NXDB and the OVSDB Plugin

Cisco Nexus Database (NXDB) is a subfeature of Cisco NX-API that enables the JavaScript Object Notation Remote Procedure Calls (JSON-RPC) processing functionality of NX-API. It enables you to configure a Cisco Nexus 9300 or 9300-EX platform switch for Layer 2 VXLAN from an external controller using JSON-RPC NX-API calls. NXDB is enabled on the switch using Cisco NX-OS.

The Open vSwitch Database (OVSDB) management protocol, as defined in RFC 7047, is a configuration protocol that allows the external controller and the Cisco Nexus 9300 or 9300-EX platform switch to communicate with one another. Cisco NX-OS does not natively support the OVSDB protocol, so an intermediate agent is needed to accept the OVSDB messages sent from the external controller and make the appropriate JSON-RPC NX-API calls. For this purpose, a separate OVSDB plugin is available that can be run either in the Guest Shell container or on an individual Linux server that is connected to the switch.

Required Hardware

One of the following switches:

·         A Cisco Nexus 9300 platform switch running Cisco NX-OS Release 7.0(3)I4(2) or a later release

·         A Cisco Nexus 9300-EX platform switch running Cisco NX-OS Release 7.0(3)I6(1) or a later release

Any NSXv controller that follows OVSDB RFC 7047 and the Open vSwitch Manual

Required Software

The N93-TP1K9=(SPARE) TP Services Package license (to use Cisco NXDB on the Cisco Nexus 9300 and 9300-EX platform switches)

The OVSDB plugin that is compatible with your Cisco NX-OS release and Cisco device:

 

Note: OVSDB plugin images are backward compatible with prior switch images. For example, 2.2.x will work with the 7.0(3)I6(x) switch image.

New Features

Table 2 lists the features that are introduced in OVSDB plugin 2.2.x and 2.3.x.

Installation and Configuration Information

For information on installing or upgrading the Cisco NX-OS image and the OVSDB plugin as well as configuring Cisco NXDB for use with NSXv controllers, see the Configuring NXDB for Cisco Nexus 9000 Series Switches and Communicating with NSXv Controllers (for Layer 2 VXLANs).

Open Caveats

Table 3 lists the open caveats for OVSDB plugin 2.3.2. Tables 4 and 5 list the open caveats for Cisco NX-OS Releases 7.0(3)I7(6) and 9.3(1) with the OVSDB plugin and with third-party VMware. Click the bug ID to access the Bug Search tool and see additional information about the bug.
