Example for Configuring the WLAN Service on Medium- and Large-Scale Campus Networks

Medium- and Large-Scale WLAN Overview

In this document, a Wireless Local Area Network (WLAN) uses 2.4 GHz or 5 GHz radio as transmission medium. WLANs are widely used due to their low cost, flexibility, scalability, and mobility compared to wired networks.

Medium and large campus WLANs are deployed in headquarters of large and medium enterprises, branches of large enterprises, colleges and universities, and airports.

Configuration Notes

  • In this example, the security policy is WPA2-PSK-CCMP. To ensure network security, choose an appropriate security policy according to your network configurations.

  • In tunnel forwarding mode, the management VLAN and service VLAN cannot be the same. If you set the forwarding mode to direct forwarding, you are not advised to configure the management VLAN and service VLAN to be the same.

  • In direct forwarding mode, configure port isolation on the interface directly connected to APs. If port isolation is not configured, many broadcast packets will be transmitted in the VLANs or WLAN users on different APs can directly communicate at Layer 2.

  • Configure the management VLAN and service VLAN:
    • In tunnel forwarding mode, service packets are encapsulated in a CAPWAP tunnel and forwarded to the AC. The AC then forwards the packets to the upper-layer network or APs. Service packets and management packets can be forwarded normally only if the network between the AC and APs is added to the management VLAN and the network between the AC and upper-layer network is added to the service VLAN.
    • In direct forwarding mode, service packets are not encapsulated into a CAPWAP tunnel, but are directly forwarded to the upper-layer network or APs. Service packets and management packets can be forwarded normally only if the network between the AC and APs is added to the management VLAN and the network between APs and upper-layer network is added to the service VLAN.
  • How to configure the source interface:
    • In V200R006, run the wlan ac source interface { loopback loopback-number | vlanif vlan-id } command in the WLAN view.
    • In V200R007 and V200R008, run the capwap source interface { loopback loopback-number | vlanif vlan-id } command in the system view.
  • No ACK mechanism is provided for multicast packet transmission on air interfaces. In addition, wireless links are unstable. To ensure stable transmission of multicast packets, they are usually sent at low rates. If a large number of such multicast packets are sent from the network side, the air interfaces may be congested. You are advised to configure multicast packet suppression to reduce impact of a large number of low-rate multicast packets on the wireless network. Exercise caution when configuring the rate limit; otherwise, the multicast services may be affected.
    • In direct forwarding mode, you are advised to configure multicast packet suppression on switch interfaces connected to APs.
    • In tunnel forwarding mode, you are advised to configure multicast packet suppression in traffic profiles of the AC.
    For details on how to configure traffic suppression, see How Do I Configure Multicast Packet Suppression to Reduce Impact of a Large Number of Low-Rate Multicast Packets on the Wireless Network?.

Networking Requirements

As shown in Figure 1, an enterprise's AC connects to the egress gateway Router of the campus network and connects to APs through a PoE switch. The PoE switch provides power to APs.

The enterprise requires a WLAN with SSID test so that users can access the enterprise internal network from anywhere and anytime. The Router needs to function as a DHCP server to assign IP addresses on 10.10.10.0/24 to users and manage users on the AC.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure the AP, AC, and upstream device to implement network interoperation.
  2. Configure the AC as a DHCP server to assign an IP address to the AP from an interface IP address pool, configure the AC as a DHCP relay agent, and configure the Router connected to the AC to assign IP addresses to STAs.
  3. Configure the WLAN service for users to connect to the Internet.

Procedure

  1. Set the NAC mode to unified mode on the AC (default setting). Configure SwitchA and the AC to allow the AP and AC to transmit CAPWAP packets.

    # Add GE0/0/1 that connects SwitchA to the AP and GE0/0/2 that connects SwitchA to the AC to the management VLAN 100.

  2. Configure the AC to communicate with the upstream device.

    # Configure VLAN 101 (service VLAN) and VLANIF 102.

    [AC] vlan batch 101 102
[AC] interface vlanif 101
[AC-Vlanif101] ip address 10.10.10.1 24

[AC] interface vlanif 102
[AC-Vlanif102] ip address 10.11.10.2 24
[AC-Vlanif102] quit

    # Configure a default route on the AC.

    [AC] ip route-static 0.0.0.0 0.0.0.0 10.11.10.1  //Configure a default route destined for Router.

    # Add GE1/0/2 that connects the AC to the Router to VLAN 102.

    [AC] interface gigabitethernet 1/0/2
[AC-GigabitEthernet1/0/2] port link-type trunk
[AC-GigabitEthernet1/0/2] port trunk allow-pass vlan 102
[AC-GigabitEthernet1/0/2] quit

  3. Configure the AC to assign an IP address to the AP and configure the Router to assign IP addresses to STAs.

    # Configure the AC to assign an IP address to the AP from an interface IP address pool.

    [AC] dhcp enable
[AC] interface vlanif 100
[AC-Vlanif100] ip address 192.168.10.1 24
[AC-Vlanif100] dhcp select interface  //Configure an interface-based address pool.
[AC-Vlanif100] quit

    # Configure the AC as the DHCP relay agent and enable user entry detection on the AC.

    [AC] interface vlanif 101
[AC-Vlanif101] dhcp select relay  //Configure the DHCP relay function.
[AC-Vlanif101] dhcp relay server-ip 10.11.10.1  //Set the DHCP server address for DHCP relay to 10.11.10.1, which resides on Router.
[AC-Vlanif101] quit

    # Configure the Router as a DHCP server to assign IP addresses to STAs.

[Router] ip route-static 10.10.10.0 24 10.11.10.2  //Configure a route on the Router destined for the network segment 10.10.10.0/24.

  4. Configure AC system parameters.

    # Configure the country code.

    [AC] wlan ac-global country-code cn
Warning: Modify the country code may delete configuration on those AP which use 
the global country code and reset them, continue?[Y/N]:y

    # Configure the AC ID and carrier ID.

    [AC] wlan ac-global ac id 1 carrier id other  //The default AC ID is 0. Set the AC ID to 1.

    # Configure the source interface.

    [AC] wlan
