WLAN roaming enables clients to seamlessly roam among APs in an ESS while retaining their IP address and authorization information during the roaming process.

NOTE:

The term "AC" in this document refers to MSR routers that can function as ACs. For information about routers that can function as ACs, see "Compatibility of MSR routers and AC functionality."

‌

WLAN roaming mechanism

As shown in Figure 5, the client roams from AP 1 to AP 2 as follows:

1. The client comes online from AP 1, and the AC creates a roaming entry for the client.

The entry records the initial SSID at association, PMKID, authentication method, security mode, and roaming VLAN.

2. The client roams to AP 2. The AC examines the roaming entry.

3. The client performs reauthentication and then comes online from AP 2.

Figure 1 WLAN roaming mechanism

‌

Layer 3 roaming

As shown in Figure 2, the client can roam between APs in different VLANs without special configuration. For the roaming procedure, see "WLAN roaming mechanism."

Figure 2 Layer 3 roaming

‌

Setting the roaming entry aging time

About this task

Client roaming entries record client PMKs, VLAN, and other authorization information. If a disconnected client connects to an AP before its roaming entry expires, the client can inherit authorization recorded in the entry and achieve fast roaming.

If a disconnected client cannot come online before its entry expires, the system deletes the entry.

Restrictions and guidelines

Setting the roaming entry aging time to 0 allows the system to delete the roaming entry of a client once the client goes offline. Fast roaming cannot be performed.

The aging time is applicable only to intra-AC roaming entries. It does not take effect on inter-AC roaming entries.

Procedure

1. Enter system view.

system-view

2. Enter service template view.

3. Set the roaming entry aging time.

client cache aging-time aging-time

By default, the roaming entry aging time is 180 seconds.

Configuring enhanced roaming

About enhanced roaming

WLAN supports the following enhanced roaming technologies:

· 802.1X fast roaming—Allows users to come online from a new AP or radio without being reauthenticated. It is applicable only when RSN+802.1X authentication is used.

· MAC fast roaming—Allows users to come online from a new AP or radio without being reauthenticated. It is applicable only when MAC authentication is used.

· 802.11r—Shortens roaming latency to reduce client disconnection rate and improve the service quality.

· Virtual BSS roaming—Enables the AC to monitor client signal strength in real time and guide clients to roam to the optimal APs in the same ESS seamlessly.

802.1X fast roaming

802.1X fast roaming mechanism

As shown in Figure 4, 802.1X fast roaming operates as follows:

1. The client comes online from AP 1 after passing RSN+802.1X authentication. AP 1 creates a roaming entry for the client.

For more information about 802.1X authentication, see "Configuring WLAN security."

2. The client roams to AP 2. The AP examines the roaming entry for the client and triggers 802.1X fast forwarding if the client carries the same PMKID as the AP.

The system uses the cached PMK to perform key negotiation and the client can associate with AP 2 without reauthentication.

NOTE:

The system supports using the following methods to cache PMKID:

· Sticky Key Caching (SKC)—Directly caches the PMKIDs generated during 802.1X authentication of clients.

· Opportunistic Key Caching (OKC)—Uses the currently associated BSSID, client MAC address, and cached PMK to generate a PMKID.

Both methods support 802.1X fast roaming without manual intervention.

Figure 4 802.1X fast roaming

Restrictions and guidelines: 802.1X fast forwarding configuration

802.1X fast roaming supports only roaming between APs managed by the same AC.

MAC fast roaming

Intra-AC roaming

Intra-AC roaming enables clients to roam among APs that are managed by the same AC.

Figure 5 Intra-AC roaming

‌

As shown in Figure 5, 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. For more information about MAC authentication, see "Configuring WLAN authentication."

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 uses RSN + 802.1X authentication and carries the same PMKID as the AC, fast roaming is used, and the client can associate with AP 2 without reauthentication. If it is not, the client must be reauthenticated before associating with AP 2.

Restrictions and guidelines: MAC fast forwarding

802.1X fast roaming supports only roaming between APs managed by the same AC.

Enabling fast-connect for MAC authenticated intra-AC roaming clients

About this task

This feature allows a MAC authentication roaming client that has been authenticated once on the AC to come online from any APs attached to the AC without re-authentication.

Restrictions and guidelines

This feature applies only to MAC authentication wireless clients whose authentication location and association location are both on the AC.

This feature affects the displayed roaming state of inter-AC roaming clients that use MAC authentication and requires special configuration for them.

· If a client has roamed between ACs, its roaming state is N/A in the output from the display wlan client verbose command.

· If the inter-AC roaming clients belong to different VLANs, you must make sure the upstream ports of all the ACs in the same roaming group permit traffic from these VLANs to pass through.

Prerequisites

Before you can configure this feature in a service template, you must disable that service template.

Procedure

1. Enter system view.

system-view

2. Enter service template view.

wlan service-template service-template-name

3. Enable fast-connect for MAC authenticated intra-AC roaming clients.

mac-authentication fast-connect enable

By default, fast-connect is enabled for MAC authenticated intra-AC roaming clients.

802.11r

About 802.11r

802.11r fast BSS transition (FT) minimizes the delay when a client roams from a BSS to another BSS within the same ESS. During 802.11r FT, a client needs to exchange messages with the target AP.

FT provides the following message exchanging methods:

· Over-the-air—The client communicates directly with the target AP for pre-roaming authentication. This method is applicable to scenarios with high requirements on roaming compatibility.

· Over-the-DS—The client communicates with the target AP through the current AP for pre-roaming authentication. This method is applicable to scenarios with high requirements on roaming performance.

Intra-AC roaming through over-the-air FT

As shown in Figure 6, the client is associated with AP 1. Intra-AC roaming through over-the-air FT uses the following process:

1. The client sends an FT authentication request to AP 2.

2. AP 2 sends an FT authentication response to the client.

3. The client sends a reassociation request to AP 2.

4. AP 2 sends a reassociation response to the client.

5. The client roams to AP 2.

Figure 6 Over-the-air FT

‌

Inter-AC roaming through over-the-DS FT

As shown in Figure 7, the client is associated with AP 1. Intra-AC roaming through over-the-DS FT uses the following process:

1. After the client comes online, the AC creates a roaming entry and saves it for the client.

2. The client sends an FT authentication request to AP 1.

3. AP 1 sends an FT authentication response to the client.

4. The client sends a reassociation request to AP 2.

5. AP 2 sends a reassociation response to the client.

6. The client roams to AP 2.

Figure 7 Intra-AC roaming through over-the-DS FT

‌

Restrictions and guidelines: 802.11r configuration

When you configure 802.11r, follow these restrictions and guidelines:

· To enable a client that does not support FT to access the WLAN, create two service templates using the same SSID: one enabled with FT and the other not.

· To prevent a client from coming online every time the periodic re-authentication timer expires, do not enable FT and 802.1X periodic re-authentication for the same service template. For more information about 802.1X periodic re-authentication, see "Configuring WLAN security."

· PTK updates are not supported for clients that have been associated with a WLAN through FT. For more information about PTK updates, see "Configuring WLAN security."

· To use FT, you must also specify an AKM mode.

· To use FT, enable RSN IE in the beacon and probe responses, configure the CCMP cipher suite, and do not use local authentication.

· 802.11r supports only intra-device roaming in the current software version.

· 802.11r takes effect only on clients associated with the AC.

· Before configuring 802.11r, make sure the service template is disabled.

· Do not enable 802.11r FT and set the WPA3 security mode or enable enhanced open system authentication at the same time. If you do so, the service template cannot be enabled. For more information about WPA3 and enhanced open system authentication, see configuring WLAN security in WLAN Security Configuration Guide.

Configuring 802.11r

1. Enter system view.

system-view

2. Enter service template view.

wlan service-template service-template-name

3. Enable FT.

ft enable

By default, FT is disabled.

4. (Optional.) Set the FT method.

ft method { over-the-air | over-the-ds }

By default, the FT method is over-the-air.

5. (Optional.) Set the reassociation timeout timer.

802.11v

About 802.11v

802.11v defines BSS transition management (BTM), which enables clients to roam to the optimal AP if the signal strength of the current AP is low or if a better AP is discovered.

As shown in Figure 9, BTM operates as follows:

1. If the RSSI of the currently associated AP is too low or the client discovered a better AP, the client sends a BTM query to the associated AP. Upon receiving the query, the AP responds with a BTM request.

A BTM request contains information about recommended BSSs.

2. Upon receiving the BTM request, the client determines whether to disconnect from the current AP and roam to a recommended AP.

3. If the client determines to perform a roaming, it sends a BTM response to the AP. If the client fails to leave the current BSS before the disassociation timer expires, the AP sends a disassociation request to the client and logs off the client.

Figure 9 BSS transition

‌

Restrictions and guidelines: 802.11v configuration

802.11v supports only intra-AC roaming in the current software version.

Enabling BTM

Restrictions and guidelines

Make sure the service template is disabled before you perform this task.

For BTM to take effect on all clients, use the bss transition-management disassociation command to enable BTM disassociation.

Procedure

1. Enter system view.

system-view

2. Enter service template view.

wlan service-template service-template-name

3. Enable BTM.

bss transition-management enable

By default, BTM is disabled.

Configuring BTM disassociation

About this task

With BTM disassociation configured, an AP sends a BTM request to a client upon receiving a BTM query from the client and guides the client for BSS transition. With forced BTM disassociation configured, the AP forcibly logs off the client if the client fails to leave the current BSS before the disassociation timer expires.

Restrictions and guidelines

Forced BTM disassociation will forcibly log off a client. Use this feature with caution.

For BTM disassociation to take effect, enable BTM first.

Procedure

1. Enter system view.

system-view

2. Enter service template view.

wlan service-template service-template-name

3. Enable BTM disassociation and configure forced disassociation.

bss transition-management disassociation { forced | recommended } [ timer time ]

By default, recommended BTM disassociation is enabled and the disassociation timeout is 90 seconds.

Example: Configuring 802.11v

Network configuration

As shown in Figure 10, configure 802.11v for the AP to guide the client to an optimal AP.

Cooperative roaming

About cooperative roaming

Cooperative roaming is defined by H3C to provide AP- and wireless client-guided roaming of wireless clients in an ESS by using IEEE802.11k, IEEE802.11r, and IEEE802.11v.

· 802.11k defines Beacon radio measurement, allowing monitoring of channel quality and resource performance on both 2.4 GHz and 5 GHz channels.

· 802.11r defines Fast BSS Transition (FT) to shorten transmission delay during client roaming, reducing disconnection rate and improving the roaming service quality.

· 802.11v defines BSS Transition Management (BTM) to guide 802.11v clients to the optimal AP, improving the access service quality.

Cooperative roaming also supports using APs to monitor 802.11v client signal strength and can proactively guide clients to better services.

Restrictions and guidelines: Cooperative roaming configuration

Cooperative roaming supports only intra-AC roaming in the current software version.

To use cooperative roaming, make sure the APs support Wi-Fi 6.

Configuring client anti-sticky

About this task

This feature enables APs to examine the signal strength of clients at the specified intervals. For an 802.11v client, its associated AP triggers a BSS transition to guide the client to a better BSS if the signal strength of the client is lower than the threshold. For a non-802.11v client, no action is performed.

With client anti-sticky enabled, the system logs off a client if the signal strength of the client cannot reach the RSSI threshold. This practice might cause frequent BSS transitions and affect user experience.

To solve this issue, configure ACL-based client anti-sticky to set different RSSI thresholds for clients matching different ACL rules.

Restrictions and guidelines

ACL-based client anti-sticky takes effect only when client anti-sticky is enabled.

You can bind only one ACL rule to a radio.

You can use the display wlan client verbose command to view client RSSIs, and configure ACL-based client anti-sticky based on the RSSIs.

Procedure

1. Enter system view.

system-view

2. Enter AP view or an AP group's AP model view.

¡ Enter AP view.

wlan ap ap-name

¡ Execute the following commands in sequence to enter an AP group's AP model view:

wlan ap-group group-name

ap-model ap-model

3. Enter radio view.

radio radio-id

4. Configure client anti-sticky.

sacp anti-sticky { disable | enable [ rssi rssi-value ] [ interval interval ] [ forced-logoff ] }

By default:

¡ In radio view, a radio uses the configuration in an AP group's radio view.

¡ In an AP group's radio view, client anti-sticky is enabled.

5. (Optional.) Configure ACL-based client anti-sticky.

¡ In radio view:

sacp anti-sticky acl { acl-number rssi rssi-value | remove }

¡ In an AP group's radio view:

sacp anti-sticky acl acl-number [ rssi rssi-value ]

By default:

¡ In radio view, a radio uses the configuration in AP group view.

¡ In an AP group's radio view, ACL-based client anti-sticky is not configured.

If you specify the remove keyword when executing the command in radio view, the radio does not perform ACL-based client anti-sticky.

Enabling an AP to obtain BSS candidate information

About this task

This feature enables an AP to send Beacon requests at specific intervals to clients that support Beacon measurement and obtain information about BSSs detected by the clients. Upon receiving such a request, a client responds with a Beacon Report frame to report BSS information.

With this feature disabled, the AP stops updating BSS candidate information and deletes all the candidates after the aging time expires.

If both this feature and BSS transition management are enabled, the system can guide clients to roam to better services based on BSS candidate information.

Restrictions and guidelines

This feature takes effect only on clients that come online after the feature is configured.

To examine if a client supports beacon measurement, use the display wlan client rm-capabilities command.

Procedure

1. Enter system view.

system-view

2. Enter AP view or an AP group's AP model view.

¡ Enter AP view.

wlan ap ap-name

¡ Execute the following commands in sequence to enter an AP group's AP model view:

wlan ap-group group-name

ap-model ap-model

3. Enter radio view.

radio radio-id

4. Enable an AP to obtain BSS candidate information.

sacp roam-optimize bss-candidate-list { disable | enable [ interval interval ] }

By default:

¡ In radio view, an AP uses the configuration in an AP group's radio view.

¡ In an AP group's radio view, the BSS candidate obtaining feature is disabled.

Enabling data transmission holding during roaming

About this task

With advanced data transmission holding during roaming enabled, the device caches the data packets and sends the cached packets to the client to reduce the packet loss when the client signal strength is lower than the RSSI threshold specified by client anti-sticky. With advanced data transmission holding during roaming disabled, the device ages out the cached packets after a period of time and will not send the packets to the client. As a best practice, enable advanced data transmission holding during roaming in the cooperative roaming scenario enabled with client anti-sticky.

Restrictions and guidelines

To make this feature take effect, enable client association at the AC and enable the AC to forward client data traffic.

This feature is not supported in an AC hierarchy network.

Procedure

1. Enter system view.

system-view

2. Enter service template view.

wlan service-template service-template-name

3. Enable advanced data transmission holding during roaming.

sacp roam-optimize traffic-hold enable advanced

By default, advanced data transmission holding during roaming is disabled.

[AC-wlan-ap-ap1-radio-1] quit

[AC-wlan-ap-ap1] quit

# (Optional.) Configure ACL-based client anti-sticky.

NOTE:

If multiple types of clients exist and the client transmit power differs greatly, client signal strength detected by the AP might have large differences. In this case, configure ACL-based client anti-sticky as a best practice.

‌

1. Create an ACL rule to permit all packets from the client. In this example, the client MAC address is CCC9-5DE2-512D.

[AC] acl number 4500

[AC-acl-mac-4500] rule permit source-mac ccc9-5de2-512d ffff-ff00-0000

[AC-acl-mac-4500] quit

2. Specify ACL 4500 for ACL-based client anti-sticky and set the RSSI threshold to 25 for radio 1 of AP ap1. If the signal strength of the client drops below –25 dBm, the AP will guide the client to roam to another AP.

[AC] wlan ap ap1

[AC-wlan-ap-ap1] radio 1

[AC-wlan-ap-ap1-radio-1] sacp anti-sticky acl 4500 rssi 25

Configuring mobility groups

About mobility groups

A mobility group contains multiple member devices among which clients can roam without IP or authorization changes. Mobility groups expand the scale in which clients can roam.

Restrictions: Hardware compatibility with WLAN roaming

For information about MSR routers that can function as ACs, see "Compatibility of hardware and AC functionality."

Restrictions and guidelines: Mobility group 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 this task

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.
