Introduction to ovsdb-plugin-2.3.1.rpm Software

The ovsdb-plugin-2.3.1.rpm package provides enhanced Open vSwitch Database (OVSDB) management capabilities for software-defined networking (SDN) environments. Designed to integrate with OpenDaylight and other SDN controllers, this plugin facilitates real-time configuration synchronization between network controllers and physical/virtual switches. Cisco officially validated this version in Q1 2025 for compatibility with Nexus 9000 series switches in ACI mode.

This release targets enterprises implementing hybrid cloud architectures, offering improved scalability for managing 10,000+ OVSDB entries in large-scale data center deployments. Compatible with CentOS 8.5+, RHEL 8.6+, and Ubuntu 22.04 LTS, it supports both IPv4 and IPv6 management planes.
