Mesh Profile
Overview
A Mesh profile contains major parameters required for configuring the Mesh function. To enable radios of an AP group or a specified AP to set up Mesh links, a Mesh profile must be applied to the radios.
Security profile: After a security profile is bound to a Mesh profile, parameters in the security profile will be used for Mesh link setup to ensure security of Mesh links. The WPA2+PSK+AES security policy is recommended for a Mesh security profile.
The security policy can be set to open system authentication only for the Mesh network in rail transportation scenarios.
- Mesh whitelist profile: A Mesh whitelist profile contains MAC addresses of neighboring APs allowed to set up Mesh links with an AP. After a Mesh whitelist profile is applied to an AP radio, only APs with MAC addresses in the whitelist can access the AP, and other APs are denied. On common Mesh networks, a Mesh whitelist must be configured for a Mesh node.
- A neighboring AP with the MAC address in the whitelist can set up a wireless virtual link with the local AP only after passing security authentication.
- On a Mesh network where ATs are deployed, after FWA is enabled in a Mesh profile, you do not need to configure a Mesh whitelist for a Mesh node. All ATs are allowed to access the Mesh node.
- AP group radio or AP radio: You can configure major feature parameters for radios in an AP group or a specified AP radio, including the working channel and bandwidth, antenna gain, transmit power, and radio coverage distance. For example, when configuring the Mesh function, configure the same channel for radios of Mesh APs.
- Radio profile: The radio profile is classified into the 2G and 5G radio profiles. You can configure other radio parameters for Mesh links through a radio profile.
- AP wired port profile: The AP wired port profile is used to configure AP wired port parameters and Mesh roles. When configuring Mesh services, you need to configure AP wired port parameters according to actual situations, enabling the Mesh network to transmit user services. For example, if direct forwarding is used on a Mesh network, you need to configure wired ports of Mesh APs to allow service VLANs to pass through.
- Mesh handover profile: After a Mesh handover profile is bound to a Mesh profile, the Mesh profile can provide the fast Mesh link handover function and apply to train-ground communication scenarios. A Mesh handover profile and the FWA mode of a Mesh profile are mutually exclusive. A Mesh handover profile cannot be referenced by the Mesh profile in which the FWA mode is enabled
By default, the system provides the Mesh profile default. By default, the security profile default-mesh with the WPA2+PSK+AES security policy is referenced by a Mesh profile regardless of whether the Mesh profile is the default profile provided by the system or a Mesh profile created by users. If the default security profile default-mesh is used, you are advised to change the security key of the profile to ensure security. The default username and password are available in WLAN Default Usernames and Passwords (Enterprise Network or Carrier).

Item |
Description |
|---|---|
Mesh ID |
Mesh ID of a Mesh profile. The value is a string of 1-32 character(s). |
RSSI threshold (dBm) |
RSSI threshold of a Mesh link, indicating the minimum RSSI of a Mesh link. The RSSI threshold of a Mesh link depends on the distance between two MPs that establish the Mesh link. If the two MPs are far from each other, a smaller RSSI threshold is recommended. If the two MPs are close to each other, a larger RSSI threshold is recommended. The value ranges from -90 to -20. The default value is -75. After the FWA mode is enabled, the value is fixed to -90. |
Client Mode |
Mesh client mode. In Mesh client scenarios, deploy trackside APs by segment (for example, only in stations) instead of along the railway line. To meet throughput or coverage efficiency requirements, configure trackside APs to work in different channels. Vehicle-mounted APs scan channels of neighboring APs to perform Mesh link handovers. By default, this function is disabled. |
FWA mode |
An outdoor Access Terminal (AT) needs to set up a Mesh link with a remote AP to provide network access for the connected users. Configure the Mesh service on the remote AP and enable Fixed Wireless Access (FWA) in the Mesh profile so that the AT can connect to the remote AP. By default, this function is disabled. |
FWA EDCA mode |
In scenarios where an AT connects to a remote AP through Mesh links, the AT automatically adjusts EDCA parameters based on the number of ATs connecting to the remote AP. In manual EDCA mode, the remote AP negotiates with the AT based on the EDCA parameters configured for the AT. |
Maximum number of links |
Maximum number of Mesh links that can be established between APs. When an AP sets up too many Mesh links with neighboring APs, network indicators, such as the throughput, cannot meet customer needs, affecting user experience. The value ranges from 1 to 32. The default value is 8. If the FWA mode is enabled, the default value is 32. |
Link aging time (s) |
Aging time of a Mesh link. If a Mesh node cannot receive Keepalive packets from a neighboring node for a period of time greater than or equal to the aging time of a Mesh link, the Mesh node considers the Mesh link disconnected and will reselect a link. In a fast changing radio environment, if the aging time of a Mesh link is set to a small value, Mesh links may be frequently disconnected or reselected, causing network flapping. If the aging time of a Mesh link is set to a large value, a Mesh node cannot reselect Mesh links in a timely manner, causing service interruption. The value range is 5 to 60. The default value is 60. |
Link information report interval (s) |
Interval at which an MP reports Mesh link information to the AC. The value range is 5 to 3600. The default value is 30. |
DHCP trusted port |
After a DHCP trusted port is enabled in a Mesh profile and the Mesh profile is applied to an AP, the AP receives the DHCP OFFER, ACK, and NAK packets sent by authorized DHCP servers and forwards the packets to STAs so that the STAs can obtain valid IP addresses and go online. By default, this function is enabled. |
ND trusted port |
After an ND trusted port is enabled in a Mesh profile and the Mesh profile is applied to an AP, the AP receives valid ND protocol packets and forwards the packets to STAs or peer APs so that the STAs can obtain valid IPv6 addresses and go online. By default, this function is enabled. |
Management Frame Rate |
|
Beacon frame rate on 2.4G radio (Mbps) |
Transmit rate of 2.4 GHz Beacon frames. Exercise caution when modifying this parameter, as it may affect STA association. |
Beacon frame rate on 5G radio (Mbps) |
Transmit rate of 5 GHz Beacon frames. Exercise caution when modifying this parameter, as it may affect STA association. |
