Cisco Wireless Network Training

Explore radio frequency fundamentals, including wireless bands and channels, carrier signals and modulation, spread spectrum and decibel, and modern techniques like ofdm in 2.4 ghz and 5 ghz networks.

Explore how IEEE 802.11 standards evolve from 802.11 a/b/g/n/ac/ax, leveraging channel aggregation and spatial multiplexing to boost data rates and efficiency across 2.4 GHz and 5 GHz.

Investigate how physical objects affect radio frequency signals through reflection, absorption, scattering, refraction, and diffraction, causing attenuation and multipath effects in indoor and outdoor environments, including MIMO considerations.

Compare antenna features and types to optimize wireless coverage, from omnidirectional and directional designs to high-gain parabolic and Yagi antennas, with polarization and beamwidth considerations.

Explore wireless network topologies, including basic and extended service sets, distribution systems, and topologies such as repeater, outdoor bridge, and mesh, with emphasis on access points, SSIDs, and IEEE 802.11 standards.

Compare autonomous, lightweight, and cloud-based access point architectures, showing how APs bridge wireless devices to the wired network with management VLANs, trunk ports, capwap tunnels, and centralized control.

Explore access point modes including local, monitor, sniffer, bridge, and flex connect; learn how each mode handles interference, fake access points, spectrum analysis, and local-traffic operation without a central WLC.

Explore wireless LAN controllers, including unified, cloud-based, Mobility Express, embedded, and Meraki options, and compare capacities for up to 6000 access points and 64,000 users.

Discover how access points automatically locate and join a wireless LAN controller via capwap discovery, with vlan, dhcp option 43, ip forward, and dns aiding cross-subnet discovery.

Explore layer 2 and layer 3 WLAN roaming as you learn how wireless LAN controllers manage mobility groups, switch access points, and preserve client IP addresses across VLANs.

Explore the lab topology for Cisco wireless networking, including router, switch, physical server with VMware ESXi, DNS and radius servers, two virtual WLCs, a 2504 WLC, and two access points.

Configure vlan 10, 20, 30, 40, and 50 on switch and esxi, set trunk ports with qos trust, enable vlan 4095, and upload the iso to the data store.

Install a wireless LAN controller on VMware ESXi, configure the virtual machine, ports, and VLANs, assign static IPs for service and management, enable 802.11 standards, and enable web access.

Configure a Cisco wireless LAN controller by setting DNS, MTP, and time zone, then create interfaces for Vlan 20, 30, 40, and 50 with IPs and DHCP settings.

Learn to create a wireless lan ssid by deleting one, naming a test ssid, enabling it on 802.11a five gigahertz, and assigning vlan 30 and subnet 192.168.30.0 with no security.

Configure dhcp, dns, and option 43 for capwap discovery, then enable flex connect and proper vlan switching so access points register and clients receive vlan 30 ips.

Explore the anatomy of a secure wireless connection, including authentication, privacy through encryption, and data integrity with message integrity checks to prevent interception and tampering.

Explore wireless client authentication methods from open and web options to 802.1x EAP methods, including LEAP, EAP-fast, EAP-tls, and PEAP, emphasizing mutual authentication with certificates.

Explore privacy and integrity methods in wireless networks, including tkip, ccmp, gcmhp, and the progression from wpa to wpa3 with protected management frames.

Create an SSID using a pre-shared key with WPA2 and WPA3 PSK for secure access. Configure radio policy, VLAN 30, and the five gigahertz band, then test connectivity.

Create local users and EAP profiles on the wireless LAN controller, configure 802.1x and EAP-fast or PAP, publish multiple SSIDs, and verify connectivity across VLANs and Wpa2 and Wpa3 Enterprise.

Enable external authentication with Cisco ISE as the radius server, configure a new ssid on the wireless LAN controller, and enforce WPA2 with 802.1x, using radius for authentication and accounting.

Learn to authenticate wifi users with an LDAP server via AAA web authentication, configuring LDAP, wireless LANs, VLAN 50, and LDAP-based access as a Radius alternative.

Learn to update Cisco wireless LAN controllers by checking access point compatibility, backing up the device, performing the update via http or tftp, and confirming software with config boot.

Verify both WLCs have the same version, domain name, mobility group, and virtual IP; copy and apply mobility group info, then enable static IP tunneling for roaming users.

Explains how to adjust five gigahertz and 2.4 ghz band settings, perform channel aggregation and consolidation, and verify 20, 40, and 80 mhz channel widths with an analysis tool.

Learn to convert lightweight access points into autonomous access points by installing autonomous iOS, configuring TFTP and FTP servers, and using the mode key and console to upload and restart.

Configure the autonomous access point, log in, and create an ssid with wpa2 pre-shared key. Publish the ssid, enable five gigahertz, save configuration, and verify with the ssid analysis program.

Learn the basics of wireless networks, install Cisco wireless LAN controller and access points, and design, set up, and secure a wireless network, while expanding skills in security and collaboration.
