Custom applications are also supported. An SMU is a software package that can be installed on a wireless controller to provide a patch fix for bugs or security resolution to an already released image. Upon successful authentication, the guest user is either allowed access to the Internet or redirected to another web site. First things first, I dug out my project from last year to hopefully the kick start I need. The channels are essentially different frequency ranges that are non-overlapping and can be assigned using a channel designator. Where multiple levels of administrative access are supported, it is recommended you enforce them, with administrators having the minimum access level required for performing their respective tasks. Take caution when using SNMPv2c, particularly when using SNMP for read/write access. For instance, there may be a microwave oven that becomes quite active around lunchtime every day. Fully configure the network and use IPv4 or IPv6 (subnetting must be included as a part of your addressing scheme). It offers enhanced security for open Wi-Fi networks with encryption of unauthenticated traffic, robust password protection against brute-force dictionary attacks, and superior data reliability for sensitive information with 192-bit encryption. PoE models operate in Combined mode. ●     The controller pair has enough additional capacity to support the Cisco FlexConnect APs. ●     If the deployment has multiple buildings, with less than 400 APs, consider configuring a single custom site tag. this paper, we are designing a network using a network simulator tool i.e. Add Cisco DNA Center for assurance. On Cisco Catalyst 9500 Series Switches - High Performance, ISSU with Cisco StackWise Virtual is supported starting from Cisco IOS XE Gibraltar 16.12.1. Don't use the default site tag. StackWise Virtual technology combines two Catalyst 9000 Series switches into a single logical network entity from the network control plane and management perspectives. You can use a single backup WLAN controller in order to provide backup for multiple primary WLAN controllers. The projects include concepts like Port Address Translation, IPsec VPN, Access-Lists, DHCP, and alike. It consist of: -BGP,EIGRP,OSPF,REDIST. Alternatively, you can configure a CPU ACL on the WLAN controller to filter management protocols. Cisco DNA Assurance provides advanced troubleshooting capabilities - including packet capture and sensors for performing network tests, machine learning / artificial intelligence (ML/AI) analytics capabilities, and Cisco DNA Spaces integration for location. Rolling updates support automatic candidate selection using Radio Resource Management (RRM)-based AP neighbor information. StackWise-160 is supported on Catalyst 9200 switch models with the support of up to 160 Gbps stack bandwidth. ◦     Improved power efficiency: Using target wake time (TWT), client devices that support the Wi-Fi 6 standard may consume less power. You can configure APs with a priority using N+1 HA. Network Requirements (1.1.1.1) When discussing network design… Cisco Prime Infrastructure is a sophisticated network management tool that can help support the end-to-end management of network technologies and services that are critical to the operation of your organization; it aligns network management functionality with the way that network administrators do their jobs. This information is synchronized with the standby switch of the stack to provide NSF / SSO failover in case the active switch fails. The medium-density designs are equivalent to the small-site campus design with the addition of a distribution layer. You may select this design for cases where densities may not be as high as supported; however, the requirements dictate needs for critical business continuity or advanced capabilities. For coverage holes that can be corrected, the controller mitigates the coverage hole by increasing the transmit power level for a specific AP that can improve the coverage. Network simulation was carried out with the aid of the Cisco Packet Tracer 5.3 software. It is also a vital part of the Networking Academy learning experience. Cisco FRA measures this and identifies APs whose 2.4 GHz radio can be selectively assigned to a role that optimizes the use of the RF spectrum. This helps mitigate against (and/or alert appropriate network operations staff about) brute force attempts to gain access to infrastructure devices. This protects the confidentiality of the information within the management session. Campus Network (CN) is a set of Virtual Local Area network (VLAN), which … It should be noted that the benefits of PMF does require wireless clients to support PMF. Cisco CleanAir is an innovation available in Cisco Catalyst 9120AX and 9130AX APs, which include the Cisco RF ASIC. It also enables services to be applied to wired and wireless traffic in a consistent and coordinated fashion. ●     Classify applications into the traffic classes. Cisco FlexConnect provides a highly cost-effective solution, enabling organizations to configure and control remote-site APs from the headquarters through the WAN, without deploying a controller in each remote site. These highly reliable and highly secure controllers are ready to deploy anywhere—including the cloud. For example, HTTP protocol (TCP port 80) can carry thousands of potential applications within it and in today’s networks seems to function more as a transport protocol, rather than as the OSI application-layer protocol that it was originally designed to be. SNMPv3 uses unique credentials (userid/password) and can also provide encryption and data authentication services to SNMP traffic. Organizations with existing WLAN deployments. The internet edge / DMZ firewall restricts access from the guest network (specific ports on the firewall need to be opened for the tunneled data connection). However, 802.11k assisted roaming, 802.11v BSS transition, coverage hole detection (CHD), and other proximity based features are managed within individual WNCd instances. In a centralized design, wireless traffic is backhauled across the network infrastructure and terminated on the physical ports. The distributed data plane allows the solution to scale more easily, avoids hair-pinning of wireless traffic through the wireless controller, and retains the ability to easily stretch the Layer-2 domain. Design Fundamentals: LAN High Availability. This is not shown in the figure above. The RRM startup mode is invoked in the following conditions: ●     In a single-controller environment, the RRM startup mode is invoked after a successful upgrade of the controller software; otherwise, it is manually initiated (see below). Cisco DNA Center translates your QoS selections into proper device configurations and deploys the configurations to the devices. This section discusses high availability specific to the implementation of wireless controller platforms. The medium-density campus design adds a single distribution layer to the access layer, which can be standalone or used as a collapsed core connected to another distribution, or other services, or perhaps connected to WAN router at a remote site that has grown large enough to need an aggregation layer. Typically, the guest WLAN is terminated outside the corporate firewall, which allows no access inbound to corporate resources, so guests may be allowed access to the Internet only. Therefore, the optional use of protected management frames (PMF) is advisable for WLANs where possible. You can gain experience by creating simple or advanced network topologies using Packet Tracer. Preferred redundancy - Single Cisco Catalyst 9800 controller connected to redundant single logical switch. You can use CLI templates within Cisco DNA Center for more advanced configuration. Cisco also offers an earlier version of Management Frame Protection (MFP) that has both infrastructure and client components. You may be able to use a shared deployment if you meet all the following requirements: ●     You have an existing local-mode controller pair at the same site as your WAN aggregation. The images are upgraded in install mode wherein each package is upgraded individually. You can typically implement administrative access control via the local user database in each infrastructure device, or via a centralized AAA server—such as Cisco ISE. For additional details, visit cisco.com and search for High Density Experience (HDX) Deployment Guide. They work in conjunction with Cisco APs in order to support business-critical wireless applications. The following are recommendations based on specific deployments: ●     If the deployment has a building with more than 400 APs, consider splitting the building into two parts from site tag perspective. CAPWAP control traffic is encrypted, with the additional option of encrypting the CAPWAP data traffic between the foreign and anchor wireless controllers. The maximum and minimum TPC power settings apply to groups of APs through the use of RF profiles within RF tags. If any of the controller ports fail, traffic is automatically migrated to one of the other ports. For highest resiliency, deploy a pair of controllers in HA SSO configuration. ●     The site is one of many small remote sites connected to a central location. The benefits of a centralized design include IP address management, simplified configuration and troubleshooting, and roaming at scale. Cisco FRA first identifies redundant APs and then manages the changing of the single XOR radio to another band. For organizations with existing WLAN in production deployments, consider Cisco Prime Infrastructure coexistence with Cisco DNA Center for network management. Opportunistic Wireless Encryption (OWE) is an extension to IEEE 802.11 that provides encryption of the wireless medium. ●     Apply special handling to the traffic classes to achieve intended network behavior. Software-Designed Access Solution Design Guide, search for Wireless Controller Configuration 802.11 Bands, search for High Density Experience (HDX) Deployment Guide, search for the Cisco CleanAir Technology: Intelligence in Action White Papers. Site tags define the properties of the central and remote sites. A centralized architecture uses the controller as a single point for managing Layer 2 security and wireless network policies. If you are an organization with a new wireless deployment, consider using Cisco DNA Center for both automation (management) and assurance. As networks and the number of services they support continue to evolve, the responsibilities of network administrators to maintain and improve their efficiency and productivity also grow. ●     Configuration Archives—Maintains an active archive of multiple iterations of configuration files for every managed device. A typical way of implementing guest user authentication is through the guest user’s web browser, a method known as web authentication or WebAuth. With TPCv1, typically power can be kept low to gain extra capacity and reduce interference. With remote workers and sites being more prevalent in today’s networks, it can be difficult to secure the network from malware and phishing attacks. Cisco Catalyst 9100 Series EWC deployments guest wireless. This allows the network administrator to leverage existing AD credentials instead of duplicating them within the AAA server. Suppose that you are the CEO of a startup which deals with network configuration for various companies. ●     A trusted edge around the network to guarantee that users cannot inject their own arbitrary priority values and to allow the organization to trust marked traffic throughout the network. The high-density large campus design has multiple distribution layers connected to a core layer and dense demands in the access layer for wired ports and WLAN devices. d����E��>�i��aV�� Cisco WLAN controllers are responsible for system-wide WLAN functions, such as security policies, intrusion prevention, RF management, QoS, and mobility. Wireless devices should connect to the network infrastructure securely where possible. ●     Policy—Defines business intent for provisioning into the network, including creation of virtual networks, assignment of endpoints to virtual networks, and policy contract definition for groups. Boosting Campus Network Design Using Cisco Packet Tracer - Free download as PDF File (.pdf), Text File (.txt) or read online for free. The software supports text, voice and video chats. Policy tags are associated with a WLAN profile and a policy profile—each with their respective attributes shown in the figure below. Authentication of end-users is accomplished via an extensible authentication protocol (EAP) session between the wireless device and the AAA server. For ease of deployment, tags can be assigned based on location and filter, as opposed to statically assigning tags. Cisco Catalyst C9404R, C9407R, C9410R, and C9606R chassis models support 1+1 supervisor redundancy (Sup-1, Sup1XL, or Sup-1XL-Y on Catalyst 9400 Series, and Sup-1 on Catalyst 9600 Series). You can accomplish this in multiple ways. What is Cisco Packet Tracer? When the supervisor or switch switches over from  the active to the hot-standby, it will continue switching IP data traffic flows in hardware. Cisco FlexConnect is a wireless solution primarily for deployments that consist of multiple small remote sites (branches) connected into a central site. A key functional advantage of the Bonjour gateway is that it can be configured to selectively reply to Bonjour service requests, thus allowing for administrative control of Bonjour services within the enterprise. Therefore, ISSU upgrades can be performed only starting from this release to a later release. An SMU is a software package that can be installed on Catalyst 9000 Series switches to provide a patch fix for bugs or security resolution to an already released image. Project made on CISCO PACKET TRACER. Many consumer devices use the same frequencies that are used for 802.11 Wi-Fi—Bluetooth headsets, microwave ovens, and many new IOT devices use different protocols but occupy the same frequencies required for operation of the WLAN. This is sometimes referred to as WPA Personal on wireless devices. This can also be extended to provide role-based access control (RBAC) for end-users through the use of AD groups. I have now started saving bits and pieces off the web since I know the project is going to need more depth this year. In this model, the fabric WLCs communicate wireless client information to the fabric control plane, and the fabric APs encapsulate traffic into the VXLAN data path. Network devices can be categorized in multiple device groups, which can function as a hierarchy based on attributes such as location, manufacturer, or role in the network.
