About WLAN roaming
WLAN roaming enables clients to seamlessly roam among APs in an ESS while retaining their IP address and authorization information during the roaming process.
WLAN roaming mechanism
Clients can roam between APs managed by ACs in the same mobility group.
Intra-AC roaming enables clients to roam among APs that are managed by the same AC.
As shown in Figure 1, intra-AC roaming uses the following procedure:
1. The client comes online from AP 1, and the AC creates a roaming entry for the client.
2. The client roams to AP 2. The AC examines the roaming entry for the client and determines whether to perform fast roaming.
If the client is an RSN + 802.1X client, fast roaming is used, and the client can be associated with AP 2 without reauthentication. If it is not, the client needs to be reauthenticated before being associated with AP 2.
Restrictions and guidelines: WLAN roaming configuration
For a service template where an AP is configured as the client authenticator, WLAN roaming is not supported. For more information about client authentication, see "Configuring WLAN authentication."
Enabling SNMP notifications for WLAN roaming
About SNMP notifications for WLAN roaming
To report critical WLAN roaming events to an NMS, enable SNMP notifications for WLAN roaming. For WLAN roaming event notifications to be sent correctly, you must also configure SNMP on the device. For more information about SNMP configuration, see Network Management and Monitoring Configuration Guide.
Procedure
1. Enter system view.
system-view
2. Enable SNMP notifications for WLAN roaming.
snmp-agent trap enable wlan mobility
By default, SNMP notifications for WLAN roaming are disabled.
Display and maintenance commands for WLAN roaming
Execute display commands in any view.

Example: Configuring intra-AC roaming
Network configuration
As shown in Figure 2, configure intra-AC roaming to enable the client to roam from AP 1 to AP 2. The two APs are managed by the same AC.
Procedure
# Create a service template named service, set the SSID to 1, and enable the service template.
[AC] wlan service-template service
[AC-wlan-st-service] ssid 1
[AC-wlan-st-service] service-template enable
[AC-wlan-st-service] quit
# Create a manual AP named ap1, and specify the AP model and serial ID.
[AC] wlan ap ap1 model WA4320H
[AC-wlan-ap-ap1] serial-id 219801A0YG8165E00001
# Bind the service template to radio 1 of AP 1.
[AC-wlan-ap-ap1-radio-1] radio enable
[AC-wlan-ap-ap1-radio-1] service-template service
[AC-wlan-ap-ap1-radio-1] quit
[AC-wlan-ap-ap1] quit
# Create a manual AP named ap2, and specify the AP model and serial ID.
[AC] wlan ap ap2 model WA4320H
[AC-wlan-ap-ap2] serial-id 219801A0YG8165E00002
# Bind the service template to radio 1 of AP 2.
[AC-wlan-ap-ap2-radio-1] radio enable
[AC-wlan-ap-ap2-radio-1] service-template service
[AC-wlan-ap-ap2-radio-1] quit
[AC-wlan-ap-ap2] quit
Verifying the configuration
# Enable the client to come online from AP 1. (Details not shown.)
# Verify that the client associates with AP 1, and the roaming status is N/A, which indicates that the client has not performed any roaming.
