Examination content analysis in EI CCIE The advantages of SD-Access Wireless

The integration of SD-Access and wireless in the EI CCIE exam is the focus we should pay attention to.

SD-Access Wireless is defined as the integration of wireless access in the SD Access architecture to obtain all the advantages of structure and DNAC automation.

Some advantages of SD-Access Wireless are:

● Centralized wireless control plane: SD-Access Wireless will also use the same innovative RF capabilities that Cisco today deployed in the Cisco Unified Wireless Network (CUWN). In terms of RRM, client startup, and client mobility, wireless operation remains the same as CUWN, which simplifies | T adoption.

● Optimized distributed data plane: The data plane is distributed on the edge switch to achieve the best performance and scalability without bringing the usual and distributed traffic (across VL.AN, subnetting, large broadcast domain, etc.) Related troubles.

● Ubiquitous L2 roaming: SD-Access Fabric allows clients to roam seamlessly throughout the campus while retaining the same IP address.

● Simplified visitors and mobile tunnels: Anchor WLC controller is no longer needed, and guest traffic can directly enter the DMZ without jumping to an external controller

● Simplified strategy: SD-Access breaks the dependence between strategy and network structure (IP address and VL.AN), and simplifies the way of defining and implementing strategies for wired and wireless clients.

● Segmentation becomes easy: segmentation is based on virtual networks (VNls) and scalable group tags (SGT) in the structure end to end, and is layered. Both wired and wireless users apply the same segmentation strategy.

The Cisco Software-Defined Access (SD-Access) solution provides consistent performance for wired and wireless clients, including host mobility, virtual network-based segmentation, SGT, and more. The Cisco Digital Network Architecture (DNA) Center simplifies the deployment and configuration of Cisco SD-Access architecture, including wireless integration.

SD Access supports two options for integrating wireless access into the network.

One option is to use the traditional Cisco Unified Wireless Network local mode configuration "on top" as a non-local service. In this mode, the SD-Access structure is just a transmission network for wireless traffic and may be useful during the migration process.

Another option is the fully integrated SD-Access Wireless, which extends the advantages of SD-Access to wireless users.

We will continue to update the integration of SD-Access and Wireless. The wireless CCIE exam is also temporarily unavailable. The written tests for EI CCIE and EW CCIE are both 350-401, which means that students who have completed 350-401 are eligible to take the EW LAB exam.
