An MP Fails to Go Online
Symptom
An MP fails to go online on a mesh network.
Possible Causes
- The MPP (root node) is offline.
- The MP (leaf node) is not imported in advance.
- The AP model is incorrect.
- The mesh link is not established properly.
- Configurations on the AC, such as the Mesh function, Mesh whitelist profile, and Mesh role, are incorrect.
- The number of links reaches the specification.
- Antennas encounter some issues. For example, the antenna model does not match the AP or the antennas are incorrectly installed.
- The distance parameter is incorrectly configured.
- The signal strength is incorrect.
- The AP has not obtained neighbor information of the peer AP.
Troubleshooting Procedure
- Check whether the MPP is online.
On a Mesh network, the MPP must go online before MPs can go online in bridging mode.
Run the display ap all command to check whether the MPP goes online. The following uses the MPP with the MAC address 845b-1275-18c0 as an example.
Some earlier versions do not support the include parameter. You can only run the display ap all command to view the parameter.
[AC-wlan-view] display ap all | include 845b-1275-18c0 Info: This operation may take a few seconds. Please wait for a moment.done. Total AP information: fault: fault [2] idle : idle [12] nor : normal [3] -------------------------------------------------------------------------------------------------------- ID MAC Name Group IP Type State STA Uptime -------------------------------------------------------------------------------------------------------- 11 845b-1275-18c0 mpp2 default 5.1.1.252 AP5030DN nor 0 5M:34S ...... -------------------------------------------------------------------------------------------------------- Total: 17
If the MPP fails to go online, locate the fault by referring to the AP login failure.
- Check whether MPs are added offline.
On a Mesh network, an MP connects to the network in wireless mode. Before an AC goes online, MPs need to be added offline.
Run the display ap all command to check whether all MPs have gone online. The following uses the MP with the MAC address 845b-1275-20c0 as an example.
Some earlier versions do not support the include parameter. You can only run the display ap all command to view the parameter.
[AC-wlan-view] display ap all | include 845b-1275-20c0 Info: This operation may take a few seconds. Please wait for a moment.done. Total AP information: fault: fault [2] idle : idle [12] nor : normal [3] -------------------------------------------------------------------------------------------------------- ID MAC Name Group IP Type State STA Uptime -------------------------------------------------------------------------------------------------------- 11 845b-1275-20c0 mp2 default 5.1.1.252 AP5030DN nor 0 5M:34S ...... -------------------------------------------------------------------------------------------------------- Total: 17
If no MP is added offline, run the ap-id ap-id ap-mac ap-mac ap-sn ap-sn command in the WLAN view to manually add an MP.
- Check whether the AP model is correct.
In V200R020C10 and earlier versions, links can be set up only between radios on APs equipped with chips of the same protocol type. For example, radios of APs with 802.11ac chips can interconnect with radios of only neighboring APs equipped with 802.11ac chips but cannot interconnect with radios of APs equipped with non-802.11ac chips. Starting from V200R021C00, Mesh links can also be set up between radios on APs equipped with 802.11ax chips and those equipped with 802.11ac chips. For example, an AirEngine 6760-51EI can set up a Mesh link with an AP8150DN. APs running V200R020C00 cannot connect to those running versions earlier than V200R020C00. However, cloud APs running V200R020C00 can connect to cloud AP2051DNs running V200R019C00.
The following table lists the protocol types of chips used by AP models.Table 14-1 Protocol types of chips used by APsAP Model

If an AP model cannot interconnect with its neighbor AP, select a correct model to establish a Mesh link.
- Check whether a Mesh link is established.
- Check Mesh link information on the AC.
[AC-wlan-view] display wlan mesh link all Info: Mesh link does not exist.
If the 5 GHz frequency band is used for bridging and radar channels are configured, it may take a long time for APs on the Mesh network to go online. In this case, run this command multiple times to check whether a Mesh link is established or whether the link is stable.
- Check Mesh link information, and Mesh link setup and disconnection records on the MPP.

The preceding command output shows that a Mesh profile is bound to radio 1 and the Mesh function is enabled.
If the Mesh function is disabled, bind a Mesh profile to the AP or AP group to enable the Mesh function.
- Check whether the whitelist profile is configured.
On a Mesh network, you must configure a whitelist profile for the peer device to establish a link.
# Run the display this command in the AP or AP group view to check whether a whitelist profile is configured.

- Check whether the Mesh role is correct.
On a Mesh network, the AP that functions as the gateway must be configured with the MPP role, and the leaf node must be configured with the MP role. If the role configuration is incorrect, Mesh links cannot be established.
# Check the AP system profile bound to an AP.[AC-wlan-view] ap-id 11 [AC-wlan-ap-11] display this # ap-name mpp2 ap-system-profile mpp radio 1 mesh-profile mesh mesh-whitelist-profile mesh channel 40mhz-plus 157 # return

[AC-wlan-view] ap-system-profile name mpp [AC-wlan-ap-system-prof-mpp] display this # mesh-role mesh-portal //mesh-portal indicates the MPP and mesh-node indicates the MP. # return
When checking the role configuration, you must check whether the role of each AP on a Mesh network is correct. If no Mesh role is configured, the default role is MP. If the Mesh role is incorrectly configured, run the mesh-role mesh-portal command in the radio view to set the Mesh role to MPP and run the mesh-role mesh-node command to set the Mesh role to MP.
- Check whether the security profile is correctly configured.
Key negotiation is important for a Mesh network. If the key bound to the MPP is different from that on an MP, a Mesh link cannot be established.
# Check the Mesh profile bound to an AP.

By default, the system provides the Mesh profile default. Both the Mesh profile default and self-defined Mesh profiles have the security profile default-mesh referenced by default. In the security profile default-mesh, the security policy is set to WPA2+PSK+AES. If the 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). If you have not obtained the access permission of the document, see Help on the website to find out how to obtain it.
- Check whether the Mesh ID in the Mesh profile is correct.
On a Mesh network, the Mesh ID is the SSID of a Mesh connection. The MPP and MP must have the same Mesh ID. Otherwise, Mesh links cannot be set up.
# Check the Mesh profile bound to an AP.
[AC-wlan-view] ap-id 11 [AC-wlan-ap-11] display this # ap-name mpp2 ap-system-profile mpp radio 1 mesh-profile mesh mesh-whitelist-profile mesh channel 40mhz-plus 157 # return

- Check information about the Mesh zero-configuration state machine and the Mesh configuration on the AP.
- Check whether the number of Mesh links reaches the upper limit.
If there are multiple APs on the network and all APs are configured with whitelists, all APs can set up Mesh links. By default, each radio of an AP supports a maximum of eight Mesh links. If an AP has established eight Mesh links, subsequent APs cannot establish Mesh links with the AP. To check the number of Mesh links established between an AP and other APs, run the following command.
[AC-wlan-view] display wlan mesh link ap-id 11 radio 1 Rf : radio ID Dis : coverage distance(100m) Ch : channel Per : drop percent(%) TSNR : total SNR(dB) P- : peer Mesh : Mesh mode Re : retry ratio(%) RSSI : RSSI(dBm) MaxR : max RSSI(dBm) ------------------------------------------------------------------------------------------------------------------- APName P-APName P-APMAC Rf Dis Ch Mesh P-Status RSSI MaxR Per Re TSNR SNR(Ch0~2:dB) ------------------------------------------------------------------------------------------------------------------- mpp2 mp d0d0-4b22-de70 1 3 157 portal normal -20 -19 0 14 71 69/64/64 ------------------------------------------------------------------------------------------------------------------- Total: 1
If the number of links reaches the threshold (8 by default), use either of the following methods to solve the problem.
- Solution 1: Adjust the threshold for the number of links to be established so that the AP can establish more links.
# Change the maximum number of Mesh links in a Mesh profile.
[AC-wlan-view] mesh-profile name mesh [AC-wlan-mesh-prof-mesh] max-link-number 20 Warning: This action may cause service interruption. Continue?[Y/N]y [ACr-wlan-mesh-prof-mesh] display this # security-profile mesh link-report-interval 5 max-link-number 20 mesh-id mesh-net link-aging-time 5 # return
- Solution 2: Use a whitelist to analyze the networking and remove other APs that do not need to set up a Mesh network with the AP to reduce unnecessary Mesh links.
# Delete unnecessary MAC addresses from the bound whitelist profile.
[AC-wlan-view] mesh-whitelist-profile name mesh [AC-wlan-mesh-whitelist-mesh] undo peer-ap mac XXXX-XXXX-XXXX
If the number of Mesh links reaches the default threshold, solution 2 is recommended.
- Solution 1: Adjust the threshold for the number of links to be established so that the AP can establish more links.
- Check whether antennas are installed correctly.
- Check whether the antenna model is correct, whether the 2.4 GHz or 5 GHz antenna is correctly selected, and whether the antenna model is matched.
- Check whether the antenna and the feeder are installed correctly.
- Check whether the two APs' antennas are aligned.
- Check whether the distance parameter is properly configured.
# Check the radio coverage distance parameter.
<AC> display ap config-info ap-id 1 Radio 0 ...... Coverage distance(100 m) : 3 ...... Radio 1 ...... Coverage distance(100 m) : 3 ......
# If the configured radio coverage distance parameter is improper, modify this parameter. For example, if the actual radio coverage distance between the MPP and MP is 600 m but the radio coverage distance parameter is set to 300 m, you need to change the radio coverage distance parameter to 600 m. Use the following commands to change the radio coverage distance parameter.

- The unit of the radio coverage distance parameter is 100 m. For example, if the configured value is 5, it indicates 500 m.
- The radio coverage distance parameter needs to be configured on both the MPP and MP.
- Check whether the signal strength is properly configured.

If the Mesh link still cannot be set up after the maximum power is configured, check whether the antenna of the outdoor AP is installed properly. For example, check whether the antenna port is fastened and whether it is in the correct position.
Check whether the antennas are aligned. For details, visit the following website:
http://support.huawei.com/enterprise/KnowledgebaseReadAction.action?contentId=KB1000062357
- Check whether the AP has obtained neighbor information of the peer AP.
If the configurations on the AC and AP antennas are correct and you can log in to the MP on the network, check whether the MP has obtained neighbor and link information of the peer AP.
- Check whether a Mesh VAP is created on the MP.
