Enterprise Wireless Network Configuration Guide

End Devices:
- Laptop: Serves as the administrative workstation for direct initial out-of-band management and GUI configuration of the Wireless LAN Controller (WLC).
- DHCP Server: Centralized server (renamed DHCP from Server0) providing IP address allocation, default gateway assignment, DNS settings, and Option 43 WLC discovery addresses across the network.
Wireless Infrastructure Devices:
- Wireless LAN Controller (WLC): Cisco 2504 Wireless LAN Controller managing all lightweight access points centrally.
- Lightweight Access Points (LAPs): Three Lightweight Access Point PG3 units positioned to provide overlapping wireless coverage across a facility, renamed as follows:
- LW0
- LW1
- LW2
Switching Infrastructure:
- Cisco Catalyst 2960 Switch: Hostnamed S1, configured with a dedicated VLAN (VLAN 99) to isolate wireless management traffic across ports FastEthernet0/1 through FastEthernet0/6.

Physical Cabling and Initial Management Link:
- Connect a straight-through Ethernet cable from the Laptop FastEthernet port to GigabitEthernet 1 (G0/1) on the WLC.
- Access the Laptop IP configuration panel and toggle the interface between Static and Dynamic (DHCP) to trigger address acquisition.
- The WLC issues an IP address in the 192.168.1.0/24 network segment, assigning 192.168.1.1 as the Default Gateway.
Web Browser Wizard Configuration Settings:
- Open a browser on the Laptop and navigate to 192.168.1.1 to access the setup wizard.
- Administrative Credentials:
- Username: admin
- Password: Cisco123
- System and Management Interface Settings:
- System Name: NTWK
- Management Interface IP Address: 192.168.10.2
- Subnet Mask: 255.255.255.0 ( $/24$ )
- Default Gateway: 192.168.10.1
- Management VLAN ID: 0 (default)
- Initial Wireless LAN (WLAN 1) Settings:
- Network Name (SSID): STUDENTS
- Security Protocol: WPA2 Personal (WPA2-PSK)
- Passphrase / Pre-Shared Key: I love network
- Guest Network: Disabled (unchecked)
- Advanced Settings:
- Virtual IP Address: Retained at factory default values.
- Apply Settings: Review initial setup parameters, click Apply, and select OK to reboot and apply parameters.

Initial Switch Hardening and Hostname Setup:
- Access privileged EXEC mode and global configuration mode:
- enable
- configure terminal
- Disable automatic domain name lookup to prevent CLI delays on mistyped commands:
- no ip domain lookup
- Configure device hostname:
- hostname S1
VLAN Creation and Interface Port Allocation:
- Create dedicated management VLAN for wireless infrastructure:
- vlan 99
- name WIRELESS
- Configure interface range FastEthernet0/1 through FastEthernet0/6 as static access ports assigned to VLAN 99:
- interface range FastEthernet0/1 - 6
- switchport mode access
- switchport access vlan 99

Server Interface Static IP Assignment:
- On the server named DHCP, navigate to Desktop -> IP Configuration and assign:
- IP Address: 192.168.10.3
- Subnet Mask: 255.255.255.0 ( $/24$ )
- Default Gateway: 192.168.10.1
DHCP Service and Option Configuration:
- Navigate to Services -> DHCP and configure the service pool:
- Service: Set to On
- Pool Name: serverPool
- Default Gateway: 192.168.10.1
- DNS Server: 192.168.10.3
- Start IP Address: 192.168.10.100
- Subnet Mask: 255.255.255.0 ( $/24$ )
- Maximum Number of Users: 50
- WLC IP Address (Option 43 Pointer): 192.168.10.2
- Click Save to activate the IP address pool.
