CCNA 200-301: Wireless, Automation & IP Services (5/6)

Quality of service prioritizes IP phones and video conferencing traffic to ensure available bandwidth and reduce packet loss, delay, and jitter.

Explore QoS mechanisms to prevent bandwidth issues by classifying traffic, marking packets, and applying congestion management, policing, and shaping to prioritize video and critical data.

Explore how network management uses automation and tools to install, provision, monitor, and test devices, ensuring performance, reachability, and security through software updates and configuration tuning.

Explore traditional and automated network management methods, including console login, notepad-based configurations for multiple devices, and inbuilt scripts and the embedded event manager for automation and alerts.

Explore centralized network management with snmp-based monitoring, dashboards, and email alerts; view device statistics, interfaces, utilization, and netflow data, and configure or restart devices via the management software.

Understand how the simple network management protocol (SNMP) powers network monitoring by collecting device statistics via a network management server and SNMP agents, using get, set, traps, and informs.

Explore the challenges of traditional network management, including growing network size, diverse operating systems, and staffing needs. See how automation mitigates bulk configuration and troubleshooting risks.

Define goals of network automation by automating tasks, device provisioning, configuration, testing, and deployment to improve availability, reduce manual work, and standardize procedures.

Explore types of network automation across local networks, wireless, data centers, and cloud, using software defined access, dna, and apis to improve efficiency and reduce human errors.

Explore automation in networking, from plug and play and initial provisioning to centralized gateway management, and implement dynamic QoS and security policy automation.

Automate software deployments and device upgrades centrally, schedule tasks, verify completion, and use artificial intelligence and machine learning to automate troubleshooting while updating topology diagrams and documentation with dynamic discovery.

Discover how network automation reduces operational costs and speeds device deployment, while improving consistency, reducing human error, and giving centralized, scalable control through automation tools and a controller.

Explore automation origination points from on-box scripts and event manager to centralized gen controllers, and learn how software defined networking shapes traffic, enforces policies, and enables AI-driven troubleshooting.

Learn software defined networking (SDN) and how a centralized controller shapes traffic by translating application requirements into dynamic forwarding rules, QoS, and security policies across the network.

Discover how sdn controllers centralize network control, shaping forwarding, security, and QoS across devices, with deployment options including physical appliances, server software, and cloud, from vendors like Cisco and Juniper.

Discover how SDN controllers enable centralized management, plug-and-play initial provisioning, and automatic, policy-driven changes that replace traditional box-by-box CLI management with controller-based networking.

Identify the three network planes, control, management, and data, and explore how SDM influences device architecture, with examples from firewalls, routing tables, routing protocols, and security policies.

The data plane forwards traffic by consulting the routing table and exit interfaces. It handles mac and ip traffic, encapsulation, acl filtering, and vpn encryption.

The control plane builds a routing database and MAC table using protocols like OSPF, guiding the data plane to forward packets.

Understand the management plane, including configuring devices, monitoring interfaces and routing tables, and collecting statistics with mp tools, net flow, and ndp-based time synchronization for logs and troubleshooting.

Explore how the management plane remains the same while SDM uses a centralized controller, enabling automated, scheduled configuration and show command execution across devices.

SDN centralizes control plane in a controller, programming forwarding decisions on network devices while the data plane remains on those devices. The controller can be anywhere as long as reachable.

Understand the SDN imperative model where the controller handles the control plane, programs routing and mac learning, and switches merely forward traffic under centralized guidance.

Explore the SDN declarative model where devices keep control-plane capabilities while the controller learns application requirements. It instructs devices to adjust forwarding, routing, and QoS policies accordingly.

Plan sdn design by selecting interoperable hardware and controllers, enable automatic provisioning, and ensure redundancy with clustered controllers, multiple paths, and security policies.

Understand underlay and overlay networks, fabric architecture, and how a separated control plane with L3 routing protocols achieves IP reachability.

Overlay networks create a virtual network on top of an underlying network. A controller uses policies to decide forwarding paths based on quality of service requirements like bandwidth and delay.

Explore the software-defined networking fabric where a controller programs devices using common protocols and languages to form a gen fabric with multiple paths and load balancing.

Explore API types, including local system APIs that run within a single computer and remote APIs that connect two different applications over a network.

Discover how APIs enable applications to communicate with SDN controllers and push configurations to networking devices, with emphasis on controller to device interactions, bandwidth, QoS, and security policies.

Explore northbound APIs in sdn networks, comparing rest api with other api types, and see how applications communicate with the controller to request topology and device information.

Explore how southbound APIs let a controller instruct network devices to forward traffic, query status, and apply configurations using OpenFlow and vendor-specific protocols.

Explore Cisco DevNet and the Cisco developer program, enabling information technology professionals to build and integrate applications with Cisco platforms through APIs, automation, and the Cisco DNA software track.

Explore DevNet certifications across data center, enterprise, and security tracks, from associate to expert, to build software skills, Python programming, APIs, REST, and network automation.

Explore the DevNet sandbox for on-demand remote access to Cisco technologies to develop, test, and automate networks with DNA, ECI, data center automation, and wireless LAN control.

Explore how to access Cisco DevNet sandbox labs, log in options, reservations, and the variety of networking, open source, data center automation, DNA, and security labs.

Learn how to access the sandbox in the DNS center, log in with your credentials, browse home options, and reserve time slots by selecting available devices and times.

Explore Cisco DNA Center, a centralized graphical interface to manage, monitor, and configure network devices from a single pane of glass, with templates, discovery, troubleshooting, health status, and policy-based QoS.

Learn how the DNA Center appliance ships with a preloaded image, deploys in standalone or cluster mode (up to three centers) for high availability and scalable device management.

Learn how DNA Center discovers and inventories network devices, manages software images, and visualizes topology across sites. Explore discoveries, inventory, and golden images for efficient network management.

Discover how Cisco DNA Center designs network hierarchy, imports topology, runs diagnostic commands, uses templates and telemetry profiles, applies group-based policies, provisions networks, and provides assurance and troubleshooting.
