Original CISCO Switch C9200 Series C9200L-48P-4X-E C9200L 48-PORT PoE+ 4 x 10G Network Essentials Switch

● The self-provisioning device feature automatically completes the software image upgrade of a Cisco Catalyst switch on the switch when it is first deployed in the network
and configuration files installed over the sage. Cisco offers turnkey solutions such as plug-and-play and pre-boot execution environment (PXE) for easy automation
Deploy.
● API-driven configurations can be used on modern network switches such as Cisco Catalyst 9200 Series switches. It supports a variety of automating functions,
YANG data model is provided with a powerful open API through NETCONF and RESTCONF, and the YANG data model can be used with off-the-shelf and customized external tools.
So as to self-allocate network resources.
● Granular visibility enables model-driven telemetry to stream data from the switch to the destination. 
Identified by subscribing to the dataset in the YANG model. The subscribed dataset is streamed to the destination at specified intervals. In addition, Cisco
IOS XE CAN ALSO PUSH MODELS. It provides near real-time network monitoring to quickly detect and fix failures.
● Seamless software upgrades and patching support for improved operating system resiliency. On the Cisco Catalyst 9200 Series Switches, think
IOS XE supports patching plus rebooting to provide fixes for critical vulnerabilities and security vulnerabilities between scheduled maintenance releases.
With this kind of support, you have to wait for the next maintenance release to add patches. Patching requires rebooting the switch after patching to make changes
Take effect.

● Reliable solutions built with Cisco Trust Anchor technology lay a solid foundation for the security of Cisco products. on the Cisco Catalyst 9200 Series
In switches, these technologies ensure the authenticity of hardware and software, thereby establishing supply chain trust and effectively alleviating the problem of software and firmware
Interhuman attack. Anchor features include image signatures, secure boots, and Cisco anchor modules.
● High availability: Cisco Catalyst 9200 Series switches support high availability features including the following:
◦ Cross-Stack EtherChannel: This is possible by configuring Cisco EtherChannel technology between the same stack members
Strong resilience.
◦ IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) independent spanning tree timers provide fast spanning tree convergence while providing Layer 2 load equalization
Balance and the benefits of distributed processing.
◦ Per-VLAN Rapid Spanning Tree (PVRST+) allows rapid spanning tree re-convergence (IEEE 802.1w) on a per-VLAN spanning tree basis,
Provides a simpler configuration than MSTP. In both MSTP and PVRST+ modes, the stacking device is used as a single spanning tree node.
◦ Switch port auto-recovery ("False forbidden
