4.2.10 Example for Configuring the WLAN Service on a Small-Scale Network (IPv6 Network)
Specifications
-
Applicable ACs: AC6605 and AC6005
- Applicable APs: all APs
- Applicable software version: V200R005C00
Networking Requirements
As shown in Figure 4-11, the AP is directly connected to the AC. An enterprise branch needs to deploy WLAN services for mobile office so that branch users can access the enterprise internal network from anywhere at any time. Wireless terminals use IPv6 addresses to connect to the wireless network.
- A WLAN named test is available.
- Branch users are assigned IP addresses on 4000::/64.
Configuration Roadmap
The configuration roadmap is as follows:
- Configure the AP, AC, and upstream device to implement Layer 2 interconnection.
- Configure the AC as a DHCPv6 server to assign IP addresses to STAs and the AP from an IP address pool.
- Configure AC system parameters, including the country code, AC ID, carrier ID, and source interface used by the AC to communicate with the AP.
- Set the AP authentication mode and add the AP to an AP region.
- Configure a VAP and deliver VAP parameters to the AP so that STAs can access the WLAN.
- Configure a WMM profile and radio profile on the AP, retain the default settings of the WMM profile and radio profile, bind the WMM profile to the radio profile to enable STAs to communicate with the AP.
- Configure a WLAN-ESS interface so that radio packets can be sent to the WLAN service module after reaching the AC.
- Configure a security profile and traffic profile on the AP, retain the default settings of the security profile and traffic profile, configure a service set, bind the WLAN-ESS interface, security profile, and traffic profile to apply security policies and QoS policies to STAs.
- Configure a VAP and deliver VAP parameters to the AP so that STAs can access the Internet through the WLAN.
Configuration Notes
-
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 on WLAN-ESS interfaces of the AC.
-
Configure port isolation on the interfaces of the device directly connected to APs. If port isolation is not configured and direct forwarding is used, a large number of unnecessary broadcast packets may be generated in the VLAN, blocking the network and degrading user experience.
-
In tunnel forwarding mode, the management VLAN and service VLAN cannot be the same. Only packets from the management VLAN are transmitted betweeen the AC and APs. Packets from the service VLAN are not allowed between the AC and APs.
Procedure
- Configure the AC so that the AP and AC can transmit CAPWAP packets.
# Configure the AC: add interface GE0/0/1 to management VLAN 100.
<AC6605> system-view [AC6605] sysname AC [AC] vlan batch 100 101 [AC] interface gigabitethernet 0/0/1 [AC-GigabitEthernet0/0/1] port link-type trunk [AC-GigabitEthernet0/0/1] port trunk pvid vlan 100 [AC-GigabitEthernet0/0/1] port trunk allow-pass vlan 100 [AC-GigabitEthernet0/0/1] quit
- Configure the AC to communicate with the upstream device.
NOTE:
Configure AC uplink interfaces to transparently transmit packets of service VLANs as required and communicate with the upstream device.
# Add AC uplink interface GE0/0/2 to service VLAN 101.

- Configure the AC as a DHCPv6 server to allocate IP addresses to STAs and the AP.
# Enable the DHCPv6 server function on the interfaces, and configure the DHCP server to allocate IP addresses to APs from the IP address pool on VLANIF 100, and allocate IP addresses to STAs from the IP address pool on VLANIF 101.
