Dynamic Service Chaining in a Data Center with Nexus Infrastructure
In a Nexus 9000 data center, ops teams now have an elegant method to insert service nodes and automatically redirect traffic using predefined rules.
Telemetry in Action: NETCONF and gNMI with a Custom-Built Collector!
Model-Driven Telemetry Telemetry is used to subscribe to meaningful data and measurements from remote devices and transport it to a receiving system for monitoring and analysis. This data allows network administrators to proactively visualize their network, and helps them automate tasks and forecast capacity requirements. When we talk about streaming telemetry, we typically refer to […]
Streamline NX-OS fabric deployments with Cisco DCNM and Red Hat Ansible
Today I will give an overview of our recent integration between Cisco Data Center Network Manager (DCNM) and Red Hat Ansible to streamline NX-OS fabric deployments. Introduction Traditionally in data center network management, configuration was often a manual, error prone process, with an operator going device by device to make changes, with every change requiring […]
Cisco NX-OS and Telegraf for Pervasive Network Visibility
Today’s networks operate at a scale where visibility is even more important for efficient operations, and legacy monitoring solutions simply do not meet the requirements. Customers want an open, reliable, and scalable method to gather data, via a model based interface, that can be easily consumed and integrated into their broader monitoring infrastructure.
Cisco NX-OS VXLAN Innovations Part 1: Inter-VNI Communication Using Downstream VNI
Acquisition and mergers involve integration of both business and IT infrastructure and there is a need for fast and seamless integration. Similarly, in shared-services scenario, tenants in a network need transparent access to the extranet or shared services in more flexible fashion. Cisco VXLAN EVPN Downstream VNI provides greater flexibility and time savings when it comes to integration of disjoint networks and shared-service deployments.
