Example for Configuring Intra-AC Roaming
Configuration Process
You need to configure and maintain WLAN features and functions in different profiles. These WLAN profiles include regulatory domain profile, radio profile, VAP profile, AP system profile, AP wired port profile, WIDS profile, and WDS profile. When configuring WLAN services, you need to set related parameters in the WLAN profiles and bind the profiles to the AP group or APs. After that, the configuration is delivered to and takes effect on the APs. WLAN profiles can reference one another; therefore, you need to know the relationships among the profiles before configuring them. For details about the profile relationships and their basic configuration procedure, see WLAN Service Configuration Procedure.
Networking Requirements
A small enterprise needs to provide WLAN services for employees. Since the WLAN needs to cover only a small area, one AC is deployed to manage APs. To differentiate department management, employees are assigned different subnets by department. The enterprise expects that users can move within the enterprise with nonstop service transmission.
As shown in Figure 6-6, an AC provides services for enterprise employees. It connects to AP_1 and AP_2 respectively.
Configuration Roadmap
The configuration
roadmap is as follows:
- Configure parameters used for communication between the AC and APs to transmit CAPWAP packets.
- Configure the AC to function as a DHCP server to assign IP addresses to the STAs and APs.
- Configure basic WLAN services so that users can connect to the wireless network.

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 in traffic profiles of the AC.
- The management VLAN and service VLAN cannot be configured the same.
When multiple VAP profiles are configured and share one service VLAN, enable inter-service VLAN proxy ARP if the data forwarding mode is set to tunnel.
Procedure
- Configure
the APs to communicate with the AC.
# Add Eth2/0/0 and Eth2/0/1 to management VLAN 100, service VLAN 101 and service VLAN 102.
You are advised to configure port isolation on Eth2/0/0 and Eth2/0/1 that connect the AC to the 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.
