In a centralized design model, the WLAN controller and APs are both located within the same site. Cisco FRA also provides a new metric, Coverage Overlap Factor, that admins can use to manually select and configure redundant radios within the deployment. It is recommended (but not required) that you run the same software version across WLCs used for N+1 HA, in order to reduce downtime as the APs establish CAPWAP sessions to the backup controllers. The traffic downtime is a concern for customers running critical applications. An organization chooses from the spectrum of switching and wireless platforms based on the needs of capacity, capabilities, and compliance. Wireless devices should connect to the network infrastructure securely where possible. Wireless clients and APs derive their configurations from the profiles contained within the tags. As with FlexConnect locally switched deployments, the guest WLAN/SSID can be locally switched to a VLAN within the branch which provides direct Internet access (DIA). You can trigger RRM startup mode from CLI, using the following command: RRM startup mode runs for 100 minutes (10 iterations at 10-minute intervals). 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. Cisco Catalyst 9800 Embedded Wireless Controller (EWC) can be built right into the access point. A University Network. 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. As a best practice, you should enable CleanAir, Persistent Device Avoidance, and ED-RRM. The Cisco EWC is an alternative to Cisco FlexConnect deployments for small wireless deployments, since a separate on-premise controller does not need to be deployed. The static route is redistributed in OSPF and advertised as an external route (E2). For organizations with existing WLAN in production deployments, consider Cisco Prime Infrastructure coexistence with Cisco DNA Center for network management. Network simulation was carried out with the aid of the Cisco Packet Tracer 5.3 software. 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. 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. WPA3-Enterprise provides higher grade security protocols for sensitive data networks. Remote sites that use Cisco FlexConnect local switching mode can also benefit from the use of multicast-based applications. Application Policy allows you device-grouping and class-of-service assignment. Distributed network analysis tools (such as packet capture and RMON probes) are often very useful elements to include in the overall campus design. A Network Topology designed using Cisco Packet Tracer. Cisco wireless LAN controllers support AP stateful switchover and client stateful switchover. For example, it may be desirable to provide restricted network access to long-term contractors, as opposed to the access granted employees. For more information, see the Software-Defined-Access Solution Design Guide, at https://cs.co/sda-sdg. Note: Fast software upgrade is supported only on access switches with a single logical uplink connection. ● Secure—Secure air, devices, and users with Cisco Catalyst 9800 Series wireless controllers. PEAP makes use of standard user credentials (userid & password) for authentication. Cisco Prime Infrastructure and Cisco DNA Center choices for WLAN deployments. For link-level resiliency on the Catalyst 9600 Series, spread uplinks ports across the switch linecards. ● Cisco DNA Spaces-based guest onboarding—Cisco DNA Spaces-based guest-onboarding is often implemented by organizations who wish to provide free Internet access within their venue, in exchange for collecting some information from customers who visit the site. 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. ◦ Improved power efficiency: Using target wake time (TWT), client devices that support the Wi-Fi 6 standard may consume less power. Cisco DNA Spaces provides organizations with rich location-based wireless services, including location analytics, business, insights, customer engagement toolkits, asset management, enterprise integrations, and location data APIs. A static route is configured through the ASA firewall to allow routing to the public wireless network. Continue to use Cisco Prime Infrastructure for reporting, compliance, configuration, and for existing device support. 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. 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. What is Cisco Packet Tracer? Policy Profiles and WLAN Profiles (which include the WLAN/SSID name) are then attached to Policy Tags, which are then attached to APs. 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. Multicast domain name services and Bonjour gateway. StackWise Virtual technology uses SSO / NSF to provide seamless traffic failover when one of the switches fails. In this guide, multicast-multicast mode is supported by using the Cisco Catalyst 9800 Series WLAN Controllers. Cisco Validated Design. Cisco CleanAir technology was released in 2010 and has continuously adapted to keep pace with the market and changing nature of the WLAN spectrum. When LAG is enabled, the wireless controller dynamically manages port redundancy and load-balances APs transparently. This increases the amount of bandwidth available for a given channel and improves the throughput and apparent speed perceived by the client. This paper relates the part of a cisco packet tracer for a case study to design and simulation virtual local area network. ED-RRM provides a safety net by doing two things: ◦ Recognizing that something is not noise but instead is intentionally transmitting and interfering with the network operations. Video and voice applications continue to grow as smartphones, tablets, and PCs are added to wireless networks in all aspects of our daily life. ● Guest Anchor is not required (currently not supported on the EWC). Cisco FRA relies on hardware capabilities as well as existing DCA in order to manage the switching of interface roles. SIP-based client software, FUTO Messenger, was developed to run on the network. Take caution when using SNMPv2c, particularly when using SNMP for read/write access. ● Intelligent—Cisco Catalyst 9800 Series wireless controllers are built on the modular Cisco IOS XE operating system, which offers a rich set of open standards-based programmable APIs and model-driven telemetry that provide an easy way to automate day-0 to day-N network operations, and deep insights into the health of your network and clients. Support for two key technologies differentiates the APs selected for deployment in the campus WLAN: ● 802.11ax (Wi-Fi 6)—The IEEE 802.11ax (Wi-Fi 6) specification provides for significant enhancements to wireless networking performance including the following: ◦ Higher capacity: Attach more devices than under previous standards through features such as orthogonal frequency-division multiple access (OFDMA) and multiuser multiple-input multiple-output (MU-MIMO). After 100 days of struggle, you have finally received your first assignment to configure the network for three different companies in such a way that all the PCs in each company must be able to communicate with each other as well as with all the PCs of any other company. The following table summarizes the APs discussed within this guide. Note: Catalyst 9800 wireless controllers support PagP and LACP as of IOS XE 17.1 and higher. ● Load—Instantaneous user load on the network. The AAA server itself can apply additional policy-based rules for authorization to the network, such device type, time of day, location, etc., depending upon the capabilities of the AAA server.
