design a network for a university campus

This mechanism, known as the spatial-reuse forwarding mechanism, boosts data plane switching performance in the stack-ring switching architecture. The QoS policy supports rules per application matched to a traffic-class and provides the following actions to be taken on each traffic-class: mark (with DSCP), police (to a rate), or drop. The stacking architecture expands form factor, switching capacity, port density, and redundancy, as well as providing a distributed data plane with a single control and management plane. SNMPv2c relies on a shared community string that is sent in clear text across the network. Cisco Catalyst 9800 Series wireless controllers are built on the three pillars of network excellence—always on, secure, and intelligent—which strengthen the network by providing the best wireless experience without compromise, while saving time and money. Throughout this update, AP and client sessions remain up. Mission critical, high density, large size networks, Best in class, high density, large size networks, Wi-Fi 6 (802.11ax), OFDMA, Uplink/Downlink MU-MIMO, BSS Coloring, Target Wake Time (TWT), Apple Features, Wi-Fi 6 (802.11ax), OFDMA, MU-MIMO, Target Wake Time (TWT), Apple Features, Wi-Fi 6 (802.11ax), Cisco RF ASIC, Uplink/Downlink OFDMA, MU-MIMO, BSS Coloring, Target Wake Time (TWT), Intelligent Capture,  Container support for applications, Apple Features, Wi-Fi 6 (802.11ax) certified, Cisco RF ASIC, Uplink/Downlink OFDMA, Uplink/Downlink MU-MIMO, BSS Coloring, Target Wake Time (TWT), Intelligent Capture,  Container support for applications, Apple Features, Three radios: 2.4 GHz (4x4), 5 GHz (4x4), and BLE, Three radios: 2.4 GHz (4x4), 5 GHz (8x8), and BLE, Four radios: 2.4 GHz (4x4), 5 GHz (4x4), Cisco RF ASIC, and BLE/IoT*, Four radios: 2.4 GHz (4x4), 5 GHz (8x8 and 4x4), Cisco RF ASIC, and BLE/IoT*, Support for Cisco Catalyst 9800 Embedded (EWC). Here’s an example: In this design we have an access layer and distribution layer. Designing a campus network may not appear as interesting or exciting as designing an IP telephony network, an IP video network, or even designing a wireless network. Note:     SMUs support patching using install mode only. Bonding channels—using multiple single channels to create a single super channel—has the advantage of providing more usable throughput to a client with the capability to use the channel. An on premises deployment of Cisco DNA Spaces is required for the following: ●     Hyperlocation—To use the Cisco Aironet 4800 Series or 3700 Series APs with a hyperlocation antenna, or to use fast path on all APs on an on-premises server, it is required to receive fast path UDP data on port 2003 from the access point and use it for location calculations. It is also recommended that you limit the number of concurrent logins from a single username. 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. When using SNMP, it is recommended that you enable SNMPv3 where possible. The browser session is re-directed to a web portal that contains a login page that requests login credentials. 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. The Fast Software Upgrade (FSU) feature significantly reduces the traffic downtime during a software upgrade. Site tags define the properties of the central and remote sites. In addition, IoT devices (as well as user devices) can see up to three times less energy consumption and more stringent security. The trunk configuration and switching platform choices from the previous design also apply here. You should consider migrating to the newer WPA3 standard, which is supported by Cisco Catalyst 9800 Series wireless controllers. model Architecture of University Campus Network that can be followed or adapted to build a robust yet flexible network that respond next generation requirements. Profiles may include additional components, not listed in the figure above. Additional security functionality besides firewalling may be applied within the Internet Edge / DMZ. In the high-density large campus, you make choices for the wired distribution and access based on the most highly available platforms for the role, the highest density and widest selection of interface options, redundant power and modular control plane, with the most advanced software feature capabilities. HA SSO functionality is not supported for N+1 HA. Cisco wireless deployments can improve the availability of the wireless network with controller recovery times in the sub-second range during a WLAN controller disruption. This increases the amount of bandwidth available for a given channel and improves the throughput and apparent speed perceived by the client. University of Maryland Global Campus. NSF allows for the forwarding of data packets to continue along known routes while the routing protocol information is being restored following a switchover. For additional information about a range WLAN controller versions, visit cisco.com and search for "Wireless Rogue Management.". ●     Addresses IoT expansion—The Cisco Catalyst 9100 Series offers multilingual support and application hosting of IoT protocols. The aim was to design a network with high-quality security and low cost, in such a way that network devices of universities in developing countries, will meet standards associated with the universities in developed countries. Figure 1: current campus design (backbone design) 8. Clients from the candidate APs are actively steered away using 802.11v packets with the "disassociation imminent" field set, to help ensure seamless network connectivity as the APs are upgraded. ●     The site is one of many small remote sites connected to a central location. Video and voice applications continue to grow as smartphones, tablets, and PCs are added to wireless networks in all aspects of our daily life. Cisco DNA Center release 1.3.1.3 and higher supports the Rogue Management application within Cisco DNA Assurance. However, the device in the active role requires time to re-establish control plane peering with IP routing neighbors. Band Select allows identification of dual-band clients and helps the devices make informed decisions about which frequency range and AP to select. Design of campus network structure The construction of the campus network will design based from the actual situation and characteristics of school. The maximum and minimum TPC power settings apply to groups of APs through the use of RF profiles within RF tags. This is critical technology for application management because it is no longer a straightforward matter of configuring an access list based on the TCP or UDP port number(s) to positively identify an application. StackWise-480 is supported on Catalyst 9300 switch models with the support of up to 480 Gbps stack bandwidth. ●     Application Control on the Cisco Catalyst 9800 Series WLC by creating an AVC-based QoS policy and attaching it to a policy profile attached to a WLAN. The Campus Data Network (CDN) includes internal building wiring, building electronics, fiber optic cabling, and network core electronics. ●     Next-generation deep packet inspection (DPI) technology called Next Generation Network-Based Application Recognition (NBAR2), which allows for identification and classification of applications. Where possible, the selection of a strong password—consisting of a minimum length, and combination of letters, numbers, and/or special characters—should be enforced. ●     Assurance—Enables health scores dashboard, client/device 360° views, node, client, and path traces. The following are some recommended projects on network design for students. Project Scope 3.1. Using the Configuration Tasks feature to apply configuration templates to many devices, administrators can save many hours of work. Also, a best practice is to limit the maximum number of APs per site tag to 400 APs. Sorry, preview is currently unavailable. Multicast in remote sites leverages the underlying WAN and LAN support of multicast traffic. If the following are true, you should consider deploying the EWC at the site: ●     Single site or multisite enterprise locations with up to 100 APs and 2,000 clients per site for Cisco Catalyst 9120AX or 9130AX Series running EWC; or up to 50 APs and 1,000 clients per site for Cisco Catalyst 9115AX and 9117AX Series running EWC. For additional details, visit cisco.com and search for High Density Experience (HDX) Deployment Guide. ●     Load—Instantaneous user load on the network. Cisco SD-Access deployments with guest wireless. The high performance collapsed backbone u… For both simplicity and efficacy, HA SSO is the preferred option for providing high availability. The startup mode consists of 10 DCA runs with high sensitivity and no dampening (making channel changes easy and sensitive to the environment) to converge to a steady state channel plan. It is often deployed along with the Cisco FlexConnect architecture in order to provide high availability across data centers for remote branches. 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. Typically, LAN can be implemented in an area as small as a dorm room to one that is as large as a university campus [1]. You can also disallow management of the WLAN controller via a wireless device, a method that may also provide additional security if the intention is to manage the wireless infrastructure from a central network operations center. 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. Beginning with Cisco IOS-XE release 16.11, Cisco Catalyst 9800 Series wireless controllers provide a way to support new AP models using APDPs. Non-PoE models operate in 1:1 redundancy mode. AP patches using Access Point Service Packs (APSPs). A rogue device becomes dangerous in the following scenarios: ●     Rogue AP with the same SSID as your network (often called a honeypot), ●     Rogue AP device also on the wired network, ●     Rogue devices set up for malicious intent by someone outside the organization. However, there is an additional consideration of power, equivalent to making lane wider or narrower (the coverage of the AP). In these scenarios, you can configure maximum and minimum transmit power limits to override TPC recommendations. APs (and wireless clients) are load balanced across the WNCd instances for better scale and performance. WPA3 leverages Simultaneous Authentication of Equals (SAE) to provide stronger protections for users against password guessing attempts by third parties. The demands in the access layer for wired ports and WLAN devices typically number in the hundreds versus the thousands for a large design, with requirements for less than a few groups of 50 or fewer APs. For organizations with existing WLAN in production deployments, consider Cisco Prime Infrastructure coexistence with Cisco DNA Center for network management. To neighboring devices a StackWise Virtual domain appears as a single logical switch or router. This allows the network administrator to leverage existing AD credentials instead of duplicating them within the AAA server. The Bonjour Gateway feature (the mDNS gateway feature most often enabled for Bonjour) snoops and caches all Bonjour service advertisements across multiple VLANs and can be configured to selectively reply to Bonjour queries. 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. Cisco DNA Center is a controller for planning, preparation, installation, and integration. The downside of this option is that guest credentials are maintained separately within the guest wireless controller. Table 6. 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 advanced wireless intrusion prevention system (wIPS). The Cisco Catalyst 9800 Series wireless controller configuration data model is based on design principles of reusability, simplified provisioning, enhanced flexibility and modularization to help manage networks as they scale up and simplify the management of dynamically changing business and IT requirements. Typically, the AAA server will implement the RADIUS protocol between itself and the WLC. Coverage Hole Detection and Mitigation algorithm. You use one of the two core options in order to meet the core needs in the high-density large campus design. So , It was partitioned into five Areas described as follow: Area one 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. With the emergence of high-density networks and the IoT, organizations are more dependent on wireless networks than ever before. SSO allows the standby supervisor / switch to immediately take over in sub-second time if the active supervisor / switch fails. For clients that are making poor roaming decisions (referred to as sticky clients), the CHDM algorithm reports a false positive. Wireless infrastructure becomes the strongest first line of defense with ETA and Cisco SD-Access. Clients that do not honor this setting are de-authenticated before the AP is reloaded. [9]. ●     A template for Cisco Flexible NetFlow v9 to select and export data (local-mode only) of interest to Cisco PI or a third-party NetFlow collector to collect, analyze, and save reports for troubleshooting, capacity planning, and compliance purposes. Medium campus suggested deployment platforms (two-tier network), Cisco Catalyst 9800-40 or Cisco Catalyst 9800-CL, Cisco Catalyst 9800-40 HA SSO pair or N+1, 1/10 Gigabit Ethernet services, MACsec, TrustSec NetFlow, 1/10 Gigabit Ethernet services, MACsec, TrustSec NetFlow, UPOE, 1/10/40 Gigabit Ethernet services, MACsec, TrustSec, NetFlow, UPOE. To logically appear as a single virtual switch, the IOS daemon (IOSd) process on the active switch of the stack centrally manages all management plane and network control plane operations with Layer 2 and Layer 3 protocols. The following figure shows an example of wireless controller link aggregation in a high availability configuration to a Cisco StackWise Virtual pair. 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. To optimally forward the traffic within the stack ring, the packet-stripping function is performed on the destination switch instead of on the source switch. DCA is aware of what channels on which you are allowed to operate and assigns these channels to be as interference-free as possible, based on over-the-air observations. ●     Software Image Management—Enables a network administrator to import software images from Cisco.com, managed devices, URLs, or file systems, and then distribute them to a single device or group of devices. Fast software upgrade is not supported if the Micro Controller Unit (MCU) Field Programmable Gate Array (FPGA) upgrade is required. The primary supervisor is active and is responsible for normal system operation. Extended Fast Software Upgrade reduces the traffic downtime during software reload or upgrade operations. This provides a way to introduce new AP models into your network without having to upgrade the wireless controller software version. ●     Deprioritized background applications and non-business entertainment-oriented applications so that these do not delay interactive or business-critical applications. An organization chooses from the spectrum of switching and wireless platforms based on the needs of capacity, capabilities, and compliance. WPA3 is the latest version of Wi-Fi Protected Access (WPA), which is a suite of protocols and technologies that provide authentication and encryption for Wi-Fi networks. This will be the source IP address of those mDNS packets that are coming out from the controller acting as mDNS Gateway.
