This allows the network administrator to leverage existing AD credentials instead of duplicating them within the AAA server.

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. Also, a best practice is to limit the maximum number of APs per site tag to 400 APs. Up to 2 hot-swappable power supplies per switch. On Cisco Catalyst 9500 Series Switches - High Performance, ISSU with Cisco StackWise Virtual is supported starting from Cisco IOS XE Gibraltar 16.12.1. To learn more, view our. The Bonjour protocol uses mDNS queries. When employees leave the organization, or move to other groups, their administrative access should be immediately revoked. Cisco Umbrella also provides network administrators visibility of Internet activity across all endpoint devices on or off the corporate network. The behavior is analogous to lanes on a highway—you only get the full benefit of the lane if it is completely separate from another lane on the same highway. There are three main phases of rogue device management in the Cisco Catalyst wireless solution: ●     Detection—Managed using RRM scanning in order to detect the presence of rogue devices. Corpus ID: 109746574. Cisco Catalyst 9800 Embedded Wireless Controller (EWC) can be built right into the access point. It is highly recommended that you deploy redundant AAA servers for high availability in case one or more servers become temporarily unavailable. The downside of this option is that guest credentials are maintained separately within the guest wireless controller. To deploy QoS, use the Application Policy feature in Cisco DNA Center to configure quality of service on the discovered switching devices in your network. Note:     SMUs are only released on long-lived Cisco IOS-XE extended maintenance releases. 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. To optimize efficiency, RRM software embedded in the Cisco Wireless LAN Controller acts as a manager to constantly monitor over-the-air metrics and control the RF transmitted. 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. NSF allows for graceful restart of L3 routing protocols, in the event of the failure of the active supervisor of a modular chassis / StackWise Virtual pair, or the failure of the active switch of a switch stack. ●     Provision—Provisions devices for management and creates fabric domains, control plane nodes, border nodes, edge nodes, fabric wireless, local-mode wireless, and external connectivity. Where possible, a maximum number of unsuccessful attempts to access the device, before the account is disabled for a period of time, should also be enforced. The local-mode design model meets the following organization demands: ●     Seamless mobility—Enables fast roaming across the campus, so that users remain connected to their session even while walking between various floors or adjacent buildings with changing subnets, ●     Ability to support rich media—Enhances robustness of voice with call admission control and multicast with Cisco VideoStream technology, ●     Centralized policy—Enables intelligent inspection through the use of firewalls, as well as application inspection, network access control, policy enforcement, and accurate traffic classification. When paired with Cisco DNA, your network works for you. High availability feature support, Active/standby control plane with local switching data plane. Cisco DNA Center translates your QoS selections into proper device configurations and deploys the configurations to the devices. The properties of a tag are defined by the policies defined within profiles associated with the tag. The maximum and minimum TPC power settings apply to groups of APs through the use of RF profiles within RF tags. After the NBAR engine recognizes applications by their discrete protocol signatures, it registers this information in a Common Flow Table so that other WLC features, such as Flexible NetFlow and QoS, can leverage this classification result. If you are only connecting a single Cisco Catalyst 9800 controller to the wired LAN, such as for an N+1 controller deployment, connect the single controller physical ports spread across redundant Cisco Catalyst switches in a Cisco StackWise Virtual pair, switch stack, or separate line cards in a highly redundant modular chassis. The flagship platforms for these options: ●     Cisco Catalyst 9600 Series—The lead high-density modular platform choice. Cisco improves on it with programmable RF ASICs. For ease of deployment, tags can be assigned based on location and filter, as opposed to statically assigning tags. They work in conjunction with Cisco APs in order to support business-critical wireless applications. Multicast is required in order to enable the efficient delivery of certain one-to-many applications, such as video and push-to-talk group communications. University of Maryland Global Campus. A medium campus consists of one large building or several buildings. This means that batteries in products such as smartphones, laptops, tablets, and IoT devices can last longer, which makes it the ideal standard. This step is sometimes accompanied with the guest user reading and agreeing to an acceptable use policy (AUP) or end-user agreement (EUA) before accessing the Internet. PoE models operate in Combined mode. StackWise Virtual technology combines two Catalyst 9000 Series switches into a single logical network entity from the network control plane and management perspectives. Note:     Cisco 802.11ac Wave 2 APs can join a Cisco EWC network and service clients, but Cisco 802.11ac Wave 2 APs cannot run the EWC function. This can result in aggressive channel reuse if there are enough APs (each one requires an operating channel) and increased co-channel interference, counter to the intended goal of throughput efficiency. These queries are sent over UDP port 5353 to these reserved group addresses: It is significant to highlight that mDNS addresses used by Bonjour are link-local multicast addresses and are only forwarded within the local Layer 2 domain, because link-local multicast is meant to stay local by design. ●     Load—Instantaneous user load on the network. 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. The job of Dynamic Channel Assignment is to track the available lanes (channels), which differ by regulations depending on the country of installation. A typical enterprise hierarchical campus network design includes the following three layers: The Core layer that provides optimal transport between sites and high performance routing The Distribution layer that provides policy-based connectivity and … We advance more wireless efficiency with Intelligent Capture, which provides Cisco DNA Center with deep analysis. This allows users to easily view any malicious domains or IP addresses attempted to be accessed by users. 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. 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. Cisco Software Defined Access – Campus Fabric and Automation of the Distribution & Access Layers. Baek-Young Choi et al. You can use a shared controller pair or a dedicated controller pair in order to deploy Cisco FlexConnect. For these reasons, you should run DCA in DBS mode. 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. 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.
