Configuring WLAN mesh
About WLAN mesh
WLAN mesh allows APs to be wirelessly connected. The APs on a WLAN mesh network can be connected directly or over multiple hops. When one AP fails, the remaining APs can still communicate with each other.
Benefits
WLAN mesh provides the following benefits:
· Low cost, high performance, and easy deployment.
· High expansibility without wires.
· Same good user experience as traditional WLANs.
WLAN mesh network
Figure 1 shows a WLAN mesh network.
APs on a WLAN mesh network are mesh points (MPs). MPs play the following roles:
· Single-purpose MP—Provides only mesh services.
· Mesh access point (MAP)—Provides both mesh and access services.
· Mesh portal point (MPP)—Provides a wired connection to a wired network.
Figure 1 WLAN mesh network diagram
Mesh profile
A mesh profile is a set of mesh protocol processing capabilities for an AP to operate on a mesh network. A mesh profile contains the following attributes:
· Mesh ID—Identifies a mesh network.
· Mesh security—Contains settings for neighbor authentication, including an authentication and key management mode, and a preshared key.
· Keepalive interval—Specifies the interval for sending keepalive packets over a mesh link. The MP with a higher MAC address sends keepalive packets at the keepalive interval to the peer end. The sending MP disconnects the mesh link if it has not received a reply before three consecutive keepalive intervals expire. The receiving MP disconnects the mesh link if it has not received keepalive packets before three consecutive keepalive intervals expire. For correct link status detection, the keepalive interval at the sending end must be equal to or less than three times the keepalive interval at the receiving end.
To form a mesh network, APs must have the same mesh ID and mesh security settings.
Neighbor discovery and mesh link establishment
MPs must operate at the same radio mode and on the same channel to discover each other. MPs can establish a mesh link after they discover each other and establish a peer relationship.
The following are the available discovery methods:
· Active scanning—The MP sends Probe Request frames to discover neighbors and establish peer relationships.
· Passive scanning—The MP listens to Beacon frames to collect information about other MPs. If there are neighbors, the AP sends Probe Request frames to request establishing a peer relationship.
This section uses active scanning to describe the neighbor discovery and mesh link establishment process.
As shown in Figure 2, MPs attempt to establish peer relationships by exchanging their mesh profiles in Probe Request and Probe Response frames.
One MP adds another MP as a mesh peer if the following conditions are met:
· The MPs' mesh profiles match.
· The Accepting Peer Links bit in the received request or response is set.
The MP peers attempt to establish a mesh link by sending a Link Open request to each other. The mesh link is established after the MP peers acknowledge the Link Open request received from each other.
Figure 2 Neighbor discovery and mesh link establishment on a WLAN mesh network
Fit APs must obtain a mesh profile from the AC before they can establish peer relationships. For this purpose, a fit AP performs the following tasks before it attempts to establish mesh peer relationships:
1. Establishes a temporary link to the first detected WLAN mesh network to discover the AC. This link can only transfer configuration data.
2. Attempts to establish CAPWAP tunnels with the AC to obtain configuration, including the mesh profile.
3. Disconnects the temporary link after obtaining the configuration.
Then, the fit AP can perform neighbor discovery and mesh link establishment to join the WLAN mesh network.
If the fit AP fails to establish CAPWAP tunnels with the AC, the fit AP will try the rest of detected mesh networks one by one.
Wireless distribution system
Wireless distribution systems (WDSs) are applications of WLAN mesh. A WDS uses the mesh links between APs to connect dispersed LANs. The APs transfer the 802.3 frames that come from the LANs in the form of 802.11s frames over the mesh links.
You can create a WDS in point-to-point or star topology by administratively making sure mesh links are established between selected APs. Alternatively, you can use the topology that is created automatically by APs through automatic neighbor discovery and mesh link establishment without administrative intervention.
Point-to-point topology
As shown in Figure 3, you can set up a mesh link between two APs to connect two LANs.
Figure 3 WDS point to point topology
Star topology
As shown in Figure 4, you can set up mesh links between one central AP and multiple leaf APs to connect multiple LANs. In this topology, all data between LANs must traverse the central AP (AP 4 in this example).
Topology created without administrative intervention
Without administrative intervention, the WDS topology depends on the result of automatic neighbor discovery and mesh link establishment between APs.
Figure 5 Automatic topology setup
VLAN
VLANs can be deployed in mesh networks for devices in different LANs to communicate with each other. Figure 6 shows the application of VLANs in high-speed railway mesh networks.
As shown in Figure 6, an AC and multiple APs are deployed in each carriage on a train. All devices are assigned to the same VLAN. Therefore, the two APs at both ends of each carriage can act as MPPs to establish mesh links with the MPPs on the adjacent carriages. Other APs provide WLAN access services. All devices communicate with the outside through the central server deployed in the middle of the train.
In this scenario, IP address conflict might occur because all ACs use the same configuration for easy configuration and maintenance. To address this issue, configure NAT on each AC and configure the mesh interfaces to allow the VLAN for MPP communications. For more information about NAT, see Network Connectivity Configuration Guide.
Figure 6 High-speed railway mesh network
MLSP
MLSP requires cooperation of both ACs and fat APs.
About this task
Mobile Link Switch Protocol (MLSP) is designed for subway application to provide stable data transmission through mesh links between onboard and trackside MPs. The onboard MPs are responsible for link selection, maintenance, and switchover.
With MLSP enabled, each onboard MP maintains one active link and multiple standby links at the same time. Only the active link is used for data transmission. An onboard MP keeps switching its active link during train movement to ensure stable data transmission.
In subway applications, signals can be transmitted over the air, in waveguides, or in linking coaxial (LCX) cables. Signals transmitted over the air are called air signal and signals transmitted in waveguides or LCX cables are called waveguide signals. As a best practice to avoid signal interference, deploy waveguides or LCX cables in areas with strong interference.
As shown in Figure 7, AP 1 through AP 4 are trackside MPs, and fat AP 1 and fat AP 2 are onboard MPs.
Figure 7 MLSP mesh network diagram
Air signal link switchover
An onboard MP uses a mesh link as a standby link if the RSSI on the link reaches or exceeds the sum of the link establishment threshold and the mesh link hold RSSI. If the MP does not have an active link, it uses the link as the active link.
An onboard MP switches to the optimal standby mesh link when one of the following conditions is met:
· The link hold timer expires and a standby link has an RSSI higher than the active link for a value that reaches or exceeds the link switchover threshold.
· The RSSI on the active link is lower than the mesh link hold RSSI.
· The RSSI on the active link reaches or exceeds the link saturation RSSI.
If no standby link is available, the MP keeps using the active link when the RSSI on the active link is lower than the mesh link hold RSSI. The MP terminates the active link when the active link RSSI reaches or exceeds the link saturation RSSI.
Waveguide signal link switchover
An MP prefers air transmission over waveguide transmission. If an MP detects both air signals and waveguide signals, it transmits signals over the air instead of in a waveguide or LCX cable.
In waveguide transmission, an onboard MP uses a link as a standby link if the link RSSI reaches or exceeds the sum of the link establishment threshold and the waveguide link hold RSSI. If the MP does not have an active link, it uses the link as the active link.
The switchover method for waveguide signal links depends on whether fast waveguide switchover is enabled. If fast waveguide switchover is enabled, an onboard MP switches to a waveguide link once the MP detects the link. If fast waveguide switchover is disabled, an onboard MP switches to the optimal standby waveguide link when one of the following conditions is met:
· The link hold timer expires and a standby link has an RSSI higher than the active link for a value that reaches or exceeds the link switchover threshold.
· The RSSI on the active link is lower than the waveguide link hold RSSI.
· The RSSI on the active link reaches or exceeds the link saturation RSSI.
If no standby link is available, the MP keeps using the active link when the RSSI on the active link is lower than the waveguide link hold RSSI. The MP terminates the active link when the active link RSSI reaches or exceeds the link saturation RSSI.
Stable link establishment
In stable link establishment mode, an onboard MP uses the first detected link as its first active link. When the maximum number of supported links is reached, an onboard MP does not replace an existing link with a newly detected link even if the new link has a higher RSSI.
MLSP proxy
This feature enables an onboard MP to proxy an onboard device (typically an onboard server) for fast downlink packet forwarding path change when link switchover occurs.
As shown in Figure 8, an onboard MP uses the MAC address of the proxied device to send gratuitous ARP packets for MAC address table update of trackside MPs. This ensures fast transmission of downlink packets over the new active link after a link switchover.
Figure 8 Fast packet forwarding path change
MLSP link switchover in garage
In subway applications, MPs set up mesh links at a fixed channel to transmit control signals and multimedia information to trains in real time to ensure safe operation of the trains and provide network services for passengers. To mitigate channel interference and enhance channel usage after a train returns to the garage, configure this feature for an onboard MP to set up a mesh link on an automatically selected channel with the trackside AP in the garage. When the train leaves the garage, the onboard MP switches to the fixed channel automatically.
Level of interval for sending keepalive requests
Onboard MPs determine whether a train has entered the garage based on the information carried in the probe responses from trackside MPs. If the train has entered the garage, onboard MPs will reduce the keepalive request sending interval based on the configured level of interval to prevent keepalive requests from consuming channel resources. A higher interval level indicates a longer interval to send keepalive requests.
Mesh peer blacklist or whitelist
You can configure the blacklist or whitelist to control whether an MP neighbor can establish a mesh link with the local MP.
If you configure both the blacklist and whitelist, only the whitelist takes effect and only MP neighbors in the whitelist can establish a mesh link with the local MP. If only the blacklist is configured, MP neighbors in the blacklist cannot establish a mesh link with the local MP.

Example: Configuring VLAN settings for a WLAN mesh network
Network configuration
As shown in Figure 10, both LAN 1 and LAN 2 belong to VLAN 2. Configure MPP 1 and MPP 2 to establish a mesh link on channel 149, and to permit traffic from VLAN 2.
Procedure
1. Configure a mesh profile:
# Create a mesh profile.
<AC1> system-view
[AC1] wlan mesh-profile 1
# Set the mesh ID to 1.
[AC1-wlan-mesh-profile-1] mesh-id 1
# Enable SAE for authentication and key management.
[AC1-wlan-mesh-profile-1] akm mode sae
# Configure a preshared key.
[AC1-wlan-mesh-profile-1] preshared-key pass-phrase simple 12345678
# Enable the mesh profile.
[AC1-wlan-mesh-profile-1] mesh-profile enable
[AC1-wlan-mesh-profile-1] quit
2. Configure a service template.
[AC1] wlan service-template service1
[AC1-wlan-st-service1] ssid mesh-network
[AC1-wlan-st-service1] service-template enable
[AC1-wlan-st-service1] quit
3. Configure settings for the MPP:
# Create an AP template for the MPP. Make sure you select the correct AP model and specify the correct serial ID.
[AC1] wlan ap mpp1 model WA6320
[AC1-wlan-ap-mpp1] serial-id 219801A28N819CE0002T
# Bind the mesh profile to radio 1 of the MPP.
[AC1-wlan-ap-mpp1] radio 1
[AC1-wlan-ap-mpp1-radio-1] mesh-profile 1
# Set the radio type for radio 1 of the MPP to 802.11n (5GHz).
[AC1-wlan-ap-mpp1-radio-1] type dot11an
# Set the working channel of the radio to 149.
[AC1-wlan-ap-mpp1-radio-1] channel 149
# Enable the radio.
[AC1-wlan-ap-mpp1-radio-1] radio enable
[AC1-wlan-ap-mpp1-radio-1] quit
4. Configure the mesh interface:
# Create mesh interface 1.
[AC1-wlan-ap-mpp1] interface wlan-mesh 1
[AC1-wlan-ap-mpp1-wlan-mesh-1] quit
# Bind the mesh interface to radio 1 of the MPP.
[AC1-wlan-ap-mpp1] radio 1
[AC1-wlan-ap-mpp1-radio-1] mesh-interface 1
[AC1-wlan-ap-mpp1-radio-1] quit
# Set the link type to trunk.
[AC1-wlan-ap-mpp1] interface wlan-mesh 1
[AC1-wlan-ap-mpp1-wlan-mesh-1] mesh-port link type trunk
# Assign the trunk port to VLAN 2.
[AC1-wlan-ap-mpp1-wlan-mesh-1] mesh-port trunk permit vlan 2
[AC1-wlan-ap-mpp1-wlan-mesh-1] quit
# Enable remote configuration assignment.
[AC1-wlan-ap-mpp1] remote-configuration enable
5. Configure AC 2 in the same way AC 1 is configured.
Verifying the configuration
# Configure VLAN-interface 2 on both AC 1 and AC 2 to verify that AC 1 and AC 2 can ping each other successfully.
