We advance more wireless efficiency with Intelligent Capture, which provides Cisco DNA Center with deep analysis. This system behavior encourages clients to use the available superior bandwidth in 5 GHz and increases the overall network capacity. The use of older security methods, such as WEP or WPA, is not recommended due to known security vulnerabilities. If a cold reload is required, users will be prompted to confirm the action. ◦     Reduced data latency by optimizing packet scheduling, which is ideal for voice, video and gaming applications. High availability feature support, Active/standby control plane with local switching data plane. SSO allows the standby supervisor / switch to immediately take over in sub-second time if the active supervisor / switch fails. ●     Noise—Any energy in the RF spectrum that cannot be demodulated as 802.11 protocol. Since DNS is a core part of the internet, it is used to block requests to malicious domains and IP addresses before a connection is established. After all APs have been installed, it is a best practice to then calibrate DCA by invoking the RRM start-up mode. 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. Support for new AP models using Access Point Device Packs (APDPs). Cisco Catalyst 9800 Series configuration model. To neighboring devices a StackWise Virtual domain appears as a single logical switch or router. 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. accessing the network or in college campus site s consisting of a single building, separate core and distribution layers are not needed. Your design must include a minimum of one Cisco 4321 router, two Cisco 2960 switches, and two PCs. Wireless controller patches using software maintenance updates (SMUs). A hot patch does not need a system reload - meaning that clients and APs will not be affected when applying the hot patch. When LAG is enabled, the wireless controller dynamically manages port redundancy and load-balances APs transparently. It frees you from having to continually monitor the network for noise and interference problems, which can be transient and difficult to troubleshoot. The combination of identity and device groups allows you to easily create authorization rules that define which network administrators can authenticate against which devices. Cisco Prime Infrastructure includes the Device Work Center. Also need to provide a report of 800-1000 words where you show your IP addressing scheme (the table), & explanation of the IP address table, how you configured the routers on both sides, and commented screenshots of testing the connections on Packet Tracer Simulator command line option. Now you can see what's happening at your properties, act on this knowledge through digitization toolkits, and extend platform capabilities by leveraging a partner app ecosystem. Cisco Catalyst 9800 Series wireless controller configuration can be managed using Cisco DNA Center, NETCONF/YANG, Cisco Prime Infrastructure, the web-based graphical user interface (GUI), or the command line interface (CLI). The campus WLAN provides ubiquitous data and voice connectivity for employees, wireless Internet access for guests, and connectivity for IoT devices. Wireless infrastructure becomes the strongest first line of defense with ETA and Cisco SD-Access. The Cisco Catalyst 9800-CL virtual form factor deployed within a private cloud is another alternative and includes the same feature set as the Cisco Catalyst 9800 Series appliances. packet tracer interface linkedin. Fully configure the network and use IPv4 or IPv6 (subnetting must be included as a part … This section also discusses the use of software maintenance updates (SMUs) for wireless controller fixes and updates, AP service packs (APSPs) for AP fixes and updates, and AP device packs for support for new AP models. The configuration model maps APs to three types of tags - policy tags, site tags, and RF tags. The medium-density designs are equivalent to the small-site campus design with the addition of a distribution layer. After completion you should be able to test the conditions imposed. To do this, RRM performs these functions: ●     RRM data collection—Collecting the metrics, ●     Transmit Power Control (TPC) algorithm—Adjusting for optimal power levels, ●     Dynamic channel assignment (DCA)—Ensuring that channel assignments do not overlap, ●     Cisco Flexible Radio Assignment (FRA)—Determines the role of the flexible radio for APs with that flexible radio capability, ●     Coverage Hole Detection and Mitigation (CHDM) algorithm—Ensuring that you have adequate coverage and detecting clients that may be in a coverage hole. 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. For example, it may be desirable to provide restricted network access to long-term contractors, as opposed to the access granted employees. The capabilities of Cisco ISE coupled with a AAA configuration on the network devices reduce the administrative issues that surround having static local account information on each device. The basic system components for a Cisco Catalyst 9800 adaptive wIPS system include: ●     Cisco 802.11ax or 802.11ac Wave 2 APs (local-mode, Cisco FlexConnect mode, or monitor mode), ●     Cisco Catalyst 9800 Series Wireless controllers (local-mode, Cisco FlexConnect, or fabric deployments), Table 5. Organizations using Cisco DNA Center can benefit from lower cost and reduced risk when deploying and maintaining their networks. The static route is redistributed in OSPF and advertised as an external route (E2). For example, if you configure a minimum transmit power of 11 dBm, then no AP will transmit below 11 dBm, unless the AP is configured manually and no longer under control of RRM. Designing for high availability in the LAN must also consider the entire lifecycle of the deployment, including the need for updates and upgrades on the network. Once the maintenance is complete, returning these metrics to their former values then smoothly restores normal traffic flow. Typically, a captive-portal model is used with WebAuth, in which guest web sessions are redirected to a portal, which authenticates the guest before allowing Internet access. ●     Always on—Seamless software updates enable faster resolution of critical issues, introduction of new APs with zero downtime, and flexible software upgrades. this paper, we are designing a network using a network simulator tool i.e. With this method of authentication, the wireless guest must first open his or her web browser, or mobile app with embedded browser, to a URL located somewhere within the Internet. ●     Secure—Secure air, devices, and users with Cisco Catalyst 9800 Series wireless controllers. The campus network design, carried out after analysis of the user and technical network requirements, was partitioned into logical and physical domains. Cisco Networking Academy, the world's largest classroom and a major player in the communication network area, offers its students a powerful network simulator - Packet Tracer. The network architecture has been designed on Cisco’s network simulation software: Cisco Packet Tracer. Supports Fast Software Upgrade (FSU) and Extended FSU. Cisco Catalyst 9100 Series APs can handle the challenges of the next-generation network. For example, a rule can give network administrators full access to all commands or limit helpdesk users to monitoring commands. On Cisco Catalyst 9500 Series Switches - High Performance, ISSU with Cisco StackWise Virtual is supported starting from Cisco IOS XE Gibraltar 16.12.1. Switch Stacks and Cisco StackWise Technology. In this paper certain dynamic networks, the internet of things and conventional on-campus network devices were suggested. This may also be necessary in other environments if there is no end-user associated with a wireless device, the wireless device does not support the ability to configure a userid & password, or the wireless device cannot support a digital certificate. ●     Investment protection with multigigabit—The Cisco Catalyst 9100 Series supports NBASE-T and IEEE 802.3bz Ethernet compatibility to seamlessly offload network traffic without bottlenecks. For other configuration needs, Cisco Prime Infrastructure enables you to define your own templates. Four power supplies which can operate in Combined or N+1 redundancy modes. After the startup mode is finished, DCA continues to run at the interval and sensitivity as specified by the organization. For comments and suggestions about this guide and related guides, join the discussion on Cisco Community at https://cs.co/en-cvds. TPCv1 is well suited for use in most deployments. When employees leave the organization, or move to other groups, their administrative access should be immediately revoked. Non-stop forwarding / stateful switchover (NSF / SSO) offers continuous packet forwarding during supervisor engine switchover. Cisco SD-Access deployments with guest wireless. Catalyst 9200 Series switches enable stacking of up to 8 switches and 416 ports using a stack-ring fabric known as either StackWise-160 or StackWise-80. As a best practice, you should enable CleanAir, Persistent Device Avoidance, and ED-RRM. Alternatively, guest traffic can be encapsulated right from the fabric edge node to the Guest Border/Control Plane node in the DMZ, providing total isolation from enterprise data traffic. This mode of operation is referred to as Cisco FlexConnect local switching and is the mode of operation described in this guide. Project made on CISCO PACKET TRACER. Non-stop forwarding (NSF) helps to suppress routing flaps in SSO enabled devices. The properties of a tag are defined by the policies defined within profiles associated with the tag. Note:     When implementing 1+1 supervisor engines on Catalyst 9400 Series switches, the active uplink ports are automatically spread across the two supervisors for link-level resiliency. Cisco Catalyst 9800-L with Performance License, Cisco Catalyst 9800 embedded on Cisco Catalyst 9000 Series Switches, Cisco Catalyst 9800 Embedded on Catalyst 9100 Series Access Points (EWC), Virtual Controller for Small Remote Sites, Virtual controller for Small, Medium, or Large Sites, 1,000, 3,000 (central), or 6,000 (FlexConnect), 10,000, 32,000 (central), or 64,000 (FlexConnect), Up to 2.1 Gbps with Central Switching (IOS XE 17.1 and higher). Another goal of campus QoS is to apply policies to at the edge to allow consistent treatment of traffic for a predictable user experience across the entire enterprise network. The Cisco EWC is a Wi-Fi solution using a Cisco Catalyst 9800 Series Wireless Controller embedded into the Cisco Catalyst 9100 Series APs. Open access guest WLANs are often implemented in order to minimize the complexity of onboarding a guest who needs only temporary wireless network connectivity. For both simplicity and efficacy, HA SSO is the preferred option for providing high availability. Cisco Catalyst 9800 Series WLCs support TPCv1 only. Within the campus wired LAN, Cisco keeps the QoS profiles as simple as possible while ensuring support for applications that need special delivery. ●     Organizations and ecosystem partners can easily build new applications. Because software license flexibility allows you to add additional APs when requirements of an organization change, you can choose the controller that will support your needs long term, but you purchase incremental access point licenses only when you need them. The following table summarizes high availability support with the various controllers. The campus local area network (LAN) is the network that supports devices people use within a location to connect to information. The trunk configuration and switching platform choices from the previous design also apply here. This design also the hierarchical network design as a hierarchical design is … Requirements for deploying Cisco SD-Access Wireless: ●     Cisco SD-Access wired fabric deployment, ●     APs with fabric mode support directly connected to Cisco SD-Access fabric edge nodes, ●     WLC with fabric mode control plane support, ●     20ms or less latency between the fabric APs and the fabric WLC, Cisco Catalyst 9800 Embedded on Catalyst 9100 Series APs (EWC) wireless design model. The resolution is very fast acting (30 seconds or less), and the information about the interference is incorporated into RRM through DCA, alerting DCA about interference disruptions related to the channel just abandoned. ●     Cisco Catalyst 9500 Series—The lead lower-density fixed platform choice. In this guide, multicast-multicast mode is supported by using the Cisco Catalyst 9800 Series WLAN Controllers. The Bonjour Gateway feature for WLCs solves the Layer 2 domain limitation for Bonjour by allowing the WLC to snoop, cache, and proxy-respond to Bonjour service requests that may reside on different Layer 2 domains. ●     Cisco RF ASIC—The custom Cisco RF ASIC, available within the Cisco Catalyst 9120AX and 9130AX Series APs, provides enhanced off-channel monitoring, improving serving radio performance by as much as 25 percent, as well as Flexible Radio Assignment (FRA), CleanAir, wireless intrusion prevention system (WIPS) and DFS detection. Cisco CleanAir is an innovation available in Cisco Catalyst 9120AX and 9130AX APs, which include the Cisco RF ASIC. In order to bond the two switches together into a single logical node, special signaling and control information must be exchanged between the two switches. Cisco Catalyst 9100 Series EWC deployments guest wireless. The venue owner may also optionally choose to display a splash page and registration form, customized for that venue location. However, in grouping multiple channels to create a single channel, larger slices of the spectrum are consumed, decreasing the overall number of non-interfering channels to use with DCA. Because real-time communication traffic is very sensitive to delay and drop, the network must ensure that this type of traffic is handled with priority so that the stream of audio or video is not interrupted. %PDF-1.7 The benefits of a centralized design include IP address management, simplified configuration and troubleshooting, and roaming at scale. Policy tags are associated with a WLAN profile and a policy profile—each with their respective attributes shown in the figure below. The following table summarizes the APs discussed within this guide. To facilitate this information exchange, a dedicated link – the StackWise Virtual link (SVL) – is used to transfer both data and control traffic between the peer switches. Most consumer devices being released today operate in one or both of two frequency ranges, or, bands. You can use a shared controller pair or a dedicated controller pair in order to deploy Cisco FlexConnect. Design Fundamentals: LAN High Availability. Cisco DNA Center release and higher supports the Rogue Management application within Cisco DNA Assurance. So , It was partitioned into five Areas described as follow: ... Cisco Packet Tracer … The Cisco Catalyst 9800-CL virtual form factor, deployed in either a private cloud or public cloud is an alternative to an appliance, since wireless traffic is typically locally terminated in a Cisco FlexConnect deployment. This will be the source IP address of those mDNS packets that are coming out from the controller acting as mDNS Gateway. This is sometimes referred to as WPA Personal on wireless devices. It also enables services to be applied to wired and wireless traffic in a consistent and coordinated fashion. Cisco Umbrella provides a first line of security for wherever users access the internet by using DNS as a security tool. RF tags are associated with a 2.4 GHz RF Profile and a 5 GHz RF Profile - with their respective attributes shown in the figure below. High-density large campus suggested deployment platforms (three-tier network), 1/10/40 Gigabit Ethernet services, MACsec, TrustSec MPLS, NetFlow, UPOE, Highest availability 1/10/40/100 Gigabit Ethernet services, MACsec, TrustSec MPLS, NetFlow, UPOE, Operate: Common Components in Campus Designs. This authentication method is also known as a captive portal. A shared administrator account limits the ability to audit who accessed a particular network device and potentially made configuration changes. Use Cisco Prime Infrastructure for reporting, compliance, configuration, and for legacy device support. Figure 5 shows a two-tier LAN network design … Cisco Packet tracer is used as a network simulator. 2 0 obj RF tags define the properties of the group of APs. Cisco Packet tracer is used as a network … The negative impacts of wireless network outages are just as impactful as outages of the wired network. CleanAir monitors the full channel bandwidth capability of a CleanAir-capable AP regardless of the deployment requirements, and as a result, it monitors the range of 20 MHz-160 MHz channels. Clients that do not honor this setting are de-authenticated before the AP is reloaded. 4 0 obj When paired with Cisco DNA, your network works for you. Rule-based mapping of users to identity groups can be based on information available in an external directory or an identity store such as Microsoft Active Directory. The use of the word campus … All guest wireless deployments—authentication and access control. StackWise-160 is supported on Catalyst 9200 switch models with the support of up to 160 Gbps stack bandwidth. The advantage of this option is that the entire management of guest wireless access is confined to the guest wireless controller within the DMZ. Whether it’s providing you with enhanced analytics or being deployed in the infrastructure (including the Cloud) of your choice, the Cisco Catalyst 9800 Series gives you the choices you need for better efficiency. With a campus network and the services that it can support, Cisco Prime Infrastructure can play a critical role in day-to-day network operations. The checklist compares the local configuration on the controller with recommended best practices and highlights all of the features that differ. The Rogue Management application allows you visualize rogue APs as well as their potential threat level (informational, potential, or high) from within Cisco DNA Center. Policy Profiles and WLAN Profiles (which include the WLAN/SSID name) are then attached to Policy Tags, which are then attached to APs. Because this interference is not recognizable as anything other than noise to the 802.11 chipset, all clients and APs typically wait for the channel to become less busy. endobj The Report Launch Pad page provides access to over 100 reports, each of which you can customize as needed. Densities and advanced software feature capabilities are not as strong of a requirement, so options with the most economical preference are shown. The preferred design strives for typical business continuity needs not requiring every redundant component offered and standard network capabilities. With N+1 HA, APs are configured with a primary, secondary, and even a tertiary WLC, as desired. However, it is possible that automatic power control will not be able to resolve some scenarios in which an adequate RF design was not possible to implement due to architectural restrictions or site restrictions—for example, when all APs must be mounted in a central hallway, placing the APs close together but requiring coverage out to the edge of the building. Since the organization’s IT department typically has no control over the hardware or software capabilities of guest wireless devices, the authentication and authorization decision is often based on only a guest userid and password.
