campus network design using cisco packet tracer

The venue owner may also optionally choose to display a splash page and registration form, customized for that venue location. Deployment Platform Choices: Campus Wired and Wireless LAN. You can create variety of … 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. Therefore, to identify applications accurately, DPI technologies such as NBAR2 are critical. The Catalyst 9600 Series supervisor engine does not support uplinks on the module itself. Site tags define the properties of the central and remote sites. Once you enable Application Visibility, the NBAR engine classifies applications for the configured WLAN. Only one system – Cisco Prime Infrastructure or Cisco DNA Center – should be allowed to make changes to the network. University-Network-Using-Cisco-Packer-Tracer. Cisco Prime Infrastructure includes the Device Work Center. 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. 38 Thrivikram, G., 2016. Most organizations’ IT departments choose to have guest wireless users authenticate first, before allowing access to the Internet. SNMPv2c relies on a shared community string that is sent in clear text across the network. The use of the word campus … It is recommended that you implement secure administrative access control to wireless infrastructure components in order to mitigate against unauthorized access. ISSU from Cisco IOS XE Fuji 16.9.x to Cisco IOS XE Gibraltar 16.10.x or Cisco IOS XE Gibraltar 16.11.x is not supported. Configure the IP addresses on your routers and switches. The projects include concepts like Port Address Translation, IPsec VPN, Access-Lists, DHCP, and alike. If the default site tag is used, APs are load balanced across the WNCd instances in a round robin fashion. With rolling AP upgrade, AP upgrades can be staggered to ensure RF coverage to clients throughout the upgrade process. By extending the support of multicast beyond that of the campus and data center, mobile users can now use multicast-based applications. The negative impacts of wireless network outages are just as impactful as outages of the wired network. Wireless devices should connect to the network infrastructure securely where possible. Preferred redundancy - Single Cisco Catalyst 9800 controller connected to redundant single logical switch. EtherChannel allows multiple physical Ethernet links to combine into one logical channel, allowing for load sharing of traffic among the links in the channel as well as redundancy in the event that one or more links in the channel fail. Key benefits of the Cisco Catalyst 9100 Series APs include the following: ●     Wi-Fi 6 and beyond—Wi-Fi 6 reduces latency and increases capacity for demanding applications on more devices. Spanning-tree treats the StackWise Virtual pair as one bridge node, instead of two. No. A proposal has not yet been provided. The main role was to subnet the IP addresses correctly.. Its an interesting problem demonstrating the concepts of Classless IP Subnetting and using RIPv2 Protocol. Cisco SD-Access is one of the many software application packages that run on DNA Center. Network simulation was carried out with the aid of the Cisco Packet Tracer 5.3 software. It is also recommended that you limit the number of concurrent logins from a single username. Cisco CleanAir is an innovation available in Cisco Catalyst 9120AX and 9130AX APs, which include the Cisco RF ASIC. 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. For more detailed information about what RRM does and how it takes its measurements, see the Radio Resource Management White Paper on cisco.com. The channels are essentially different frequency ranges that are non-overlapping and can be assigned using a channel designator. 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. ●     Integration with Cisco DNA Center or Prime Infrastructure—To provide location data to Cisco DNA Center or Prime Infrastructure, an on-premise server is currently required. ●     If the deployment has a roaming domain that spans across multiple buildings, with more than 400 APs, consider configuring a Site Tag per building. The trunk's native VLAN is used for all CAPWAP communication between the AP and the controller. The logical design of the network will be issued. High availability feature support. Cisco SD-Access deployments with guest wireless. It then automatically adjusts associated and nearby APs to optimize coverage and capacity. Cisco Prime Infrastructure supports the management of CleanAir enabled wireless APs, enabling administrators to see interference events. The images are upgraded in install mode wherein each package is upgraded individually. Roaming across site tags for Cisco FlexConnect APs results in a client full reauthentication. Band Select allows identification of dual-band clients and helps the devices make informed decisions about which frequency range and AP to select. In a centralized design, wireless traffic is backhauled across the network infrastructure and terminated on the physical ports. Cisco Packet tracer is used as a network simulator. Contribute to riyadatik/A-University-Network-using-Cisco-Packet-Tracer- development by creating an account on GitHub. The fast software upgrade feature is supported on both stacking and standalone systems from IOS XE 16.8.1a and higher. 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. Cisco Prime Infrastructure provides the Alarms and Events feature, which is a unified display with detailed forensics. Use Cisco Prime Infrastructure for reporting, compliance, configuration, and for legacy device support. The campus local area network (LAN) is the network that supports devices people use within a location to connect to information. Cisco Catalyst 9100 Series APs can handle the challenges of the next-generation network. Using this information, RRM can periodically reconfigure the 802.11 RF network for best efficiency. ●     Interference—Other 802.11 devices operating nearby that can be heard by your network. It also enables services to be applied to wired and wireless traffic in a consistent and coordinated fashion. Using a network management solution can enable and enhance the operational efficiency of network administrators. For example, it may be desirable to provide restricted network access to long-term contractors, as opposed to the access granted employees. 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. 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. 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. Verify the network using at least five show commands. December 25, 2011 // 0. This type of deployment does not require any dedicated guest anchor controller to be deployed. Computer network … The software supports text, voice and video chats. 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. Campus Network for High Availability Design Guide . A shared administrator account limits the ability to audit who accessed a particular network device and potentially made configuration changes. Extended Fast Software Upgrade uses graceful restart capability (a feature of Cisco NSF) to ensure that device configurations, such as certain routing protocols, remain unaffected during a software upgrade or reload. Once the traffic moves away from the device, maintenance actions can be undertaken. ◦     Improved security: WPA3 is certified with Wi-Fi 6 and provides a greater value proposition than WPA2 for enterprise Wi-Fi networks. packet tracer interface linkedin. In this small campus design, core and distribution functions are collapsed on the same L3 switch. For Cisco FlexConnect guest deployments, the guest WLAN/SSID can be centrally switched and anchored through a dedicated guest controller in an Internet DMZ segment. Found it useful if only for the layout/ format I used. 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. ●     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. A University Network. Within a StackWise Virtual domain, one device is designated as the active switch and the other is designated as the standby switch. On Cisco Catalyst 9800 Series wireless controllers, the checklist separates best practices into four broad categories: infrastructure, security, RF management, and Apple devices. If a cold reload is required, users will be prompted to confirm the action. In this article we are going to design a smart campus architecture by connecting various IoE devices designed by using a cisco packet tracer simulator. Fully configure the network and use IPv4 or IPv6 (subnetting must be included as a part of your addressing scheme). For additional information about a range WLAN controller versions, visit cisco.com and search for "Wireless Rogue Management.". The browser session is re-directed to a web portal that contains a login page that requests login credentials. The preferred design strives to minimize cost with minimal numbers of components and features offered, though advanced and mission critical options are available choices for networks that require these capabilities. You make choices for the wired distribution and access with a bias towards size and flexibility in order to accommodate the space and power requirements of medium sized installations in a way that can elastically expand as an organization grows. 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. APSP rollout can be based upon sites, with the fix predownloaded and rolled out to only affected AP models. ●     Load—Instantaneous user load on the network. ◦     Forcing the AP away from the problematic channel to a channel where operations can resume. 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. You can use CLI templates within Cisco DNA Center for more advanced configuration. To neighboring devices a StackWise Virtual domain appears as a single logical switch or router. Without a centralized access and identity policy enforcement point, it's difficult to ensure the reliability of a network as the number of network devices and administrators increases. ●     The site is one of many small remote sites connected to a central location. When the primary controller fails, the AP CAPWAP state machine is restarted. Here functioning of IoT through Node Micro-control Univ (MCU) … The next-generation wireless stack is built around these main hardware and software components: ●     Cisco Catalyst 9800 Series WLAN controllers (including appliances, virtual, and embedded), ●     Cisco DNA Center (assurance and automation), ●     Cisco Prime Infrastructure (additional automation for more complex deployments), Cisco Catalyst 9800 Series wireless controllers. ●     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. A Network Topology designed using Cisco Packet Tracer. 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. Note:     SMUs are only released on long-lived Cisco IOS-XE extended maintenance releases. In these scenarios, you can configure maximum and minimum transmit power limits to override TPC recommendations. 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. Cisco DNA Center supports integration using APIs. StackPower (up to 4 switches per stack) operating in shared or redundant mode. CleanAir can report analysis and findings through the WLAN controller. It is highly recommended that you deploy redundant AAA servers for high availability in case one or more servers become temporarily unavailable. They work in conjunction with Cisco APs in order to support business-critical wireless applications. As the number of infrastructure devices within the network grows, the administrative burden of configuring individual local administrator accounts on each infrastructure device can become unmanageable. SNMPv3 uses unique credentials (userid/password) and can also provide encryption and data authentication services to SNMP traffic. Additionally, these responses may be selectively controlled by administrative policies, so that only certain Bonjour services will be permitted in specific Layer 2 domains. I have now started saving bits and pieces off the web since I know the project is going to need more depth this year. AAA logs and accounting may be used to provide an audit trail of each employee’s access to the wireless network infrastructure. APs (and wireless clients) are load balanced across the WNCd instances for better scale and performance. For additional details, visit cisco.com and search for the Cisco CleanAir Technology: Intelligence in Action White Papers. 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. Access via non-encrypted protocols such as HTTP and Telnet should be disabled where possible. In other words, the device with which the guest is accessing the network may not be considered for any policy decision. LAG requires an EtherChannel Port Group to be configured on the attached Cisco Catalyst switch. For Cisco SD-Access Wireless and for basic non-fabric wireless designs, Cisco DNA Center workflows provide automation of the wireless deployment. 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. However, 802.11k assisted roaming, 802.11v BSS transition, coverage hole detection (CHD), and other proximity based features are managed within individual WNCd instances. With the introduction of 802.11n, 802.11ac Wave 1 and Wave 2, and 802.11ax, you can use multiple channels together as a single assignment on a given AP. Cisco FRA also provides a new metric, Coverage Overlap Factor, that admins can use to manually select and configure redundant radios within the deployment. Cisco Digital Network Architecture (Cisco DNA) provides a roadmap to digitization and a path to realize immediate benefits of network automation, assurance, and security. The use of an external directory or data store can also provide a single point to grant or revoke credentials, not only for administrative access control to multiple infrastructure devices, but for access to other resources within the organization. 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. Cisco Prime Infrastructure provides you a single launch point for all reports that you can configure, schedule, and view. Note:     Catalyst 9800 wireless controllers support PagP and LACP as of IOS XE 17.1 and higher. 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. Centralized deployments with guest wireless. In this project, we used the Cisco Packet Tracer software for designing this network module. By positioning the web authentication login portal in a central server, the network administrator can provide one unified login page—with an optional AUP or EUA—for all wireless guest access without having to create a separate login page on each guest wireless controller. 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. To mitigate the concerns about unavailability of network resources, campus LAN designs include high availability / resiliency options, such as redundant links, switches, and switch components. Cisco FlexConnect is a wireless solution primarily for deployments that consist of multiple small remote sites (branches) connected into a central site. INTRODUCTION Nowadays network is a strategic instrument that must be accessible anytime from anywhere. Using the existing campus wired and wireless infrastructure for guest access provides a convenient, cost-effective way to offer Internet access for visitors and contractors. Each WLC must be managed separately, can run different hardware, and can be deployed in different datacenters across the WAN link. Campus Network (CN) is a set of Virtual Local Area network (VLAN), which … PoE models operate in Combined mode. The aim of this wireless Packet Tracer lab is to configure a campus network allowing authenticated enterprise users to access enterprise ressources using their mobile devices while … In such a deployment, an access-control list (ACL) deployed on the Layer 3 switch adjacent to the WLAN controller can limit access to the management interface.
