How to configure terminal location on the AC

10

Terminal location technology enables APs to collect strength information about radio signals in the surrounding environment to locate Wi-Fi terminals and rogue APs. APs collect radio signals of terminals in the surrounding environment and report the collected information to a location server. Then the location server computes the terminal location based on APs�?location and the wireless signal strength, and displays the computing results to users.
To configure terminal location on the AC in V200R003 and V200R005, perform the following steps:
1. Run the ap ap-id radio radio-id command in the WLAN view to enter the specified AP radio view. The variable ap-id is used to specify the AP ID while radio-id specifies the radio ID
2. Run the work-mode {normal | hybrid | monitor} command in the radio view to configure the AP radio working mode.
By default, an AP radio works in normal mode.
Notes:
An AP supports the following radio working modes:
-normal: transmits common WLAN service data. The normal AP used in terminal location can only obtain information about its connected terminals. To locate a terminal, at least three APs are required. The terminal cannot connect to the three APs concurrently; therefore, they cannot all work as normal APs. A normal AP must work with monitor or hybrid APs in terminal location.
-hybrid: periodically switches between the working channel and probe channel so that the AP can provide functions of service transmission and detection. If users require that the AP perform terminal location without compromising WLAN regular services, configure the AP to work in hybrid mode.
-monitor: The AP working in monitor mode does not provide basic WLAN services. It only provides WLAN services with monitoring functions, such as Wireless Intrusion Detection System (WIDS), spectrum analysis, and terminal location. Monitor APs do not need to switch between the working channel and probe channel; therefore, they operate at high efficiency in terminal location.
3. Run the location enable command in the radio view to enable terminal location on an AP.
4. Run the channel scan-switch enable command in the radio view to enable all-channel scanning on an AP.
If WIDS, spectrum analysis, background neighbor probing, or terminal location is configured on an AP radio, the radio cannot be used to set up a WDS bridge or Mesh link.
5. Run the location ap report-server {ac | ip-address {ipv4-address | ipv6 ipv6-address}} port port-num command in the WLAN view to configure the destination IP address and port number for the AP to report channel scan information.
The variable ipv4-address specifies the server IPv4 address to which the AP reports terminal location data, ipv6-address specifies the server IPv6 address to which the AP reports terminal location data, and port-num specifies the destination port number used by the AP to report location data.
6. Run the commit {all | ap ap-id} command in the WLAN view to commit the configuration to the AP. The variable ap-id is used to specify the AP ID.

Terminal location technology enables APs to collect strength information about radio signals in the surrounding environment to locate Wi-Fi terminals and rogue APs. APs collect radio signals of terminals in the surrounding environment and report the collected information to a location server.

Method of downloading the web package of a WLAN device
Method of downloading the web package of a WLAN device: To obtain the web file, log in to Huawei's support website (http://support.huawei.com/enterprise), download the corresponding web file according to the product model and version. The file name is in the format of "product name+software version.web file version.web.zip". The web file of the WLAN device is also integrated into the system software package and does not need to be loaded separately. You can directly run the HTTP service. By default, the device loads the web file included in the system software package.

Dot1Q termination: Create a sub-interface on the CE interface of the device, and run the dot1q termination vid pe-vid command to configure a termination VLAN for the sub-interface. QinQ termination: Create a sub-interface on the CE interface of the device, and run the qinq termination pe-vid pe-vid ce-vid ce-vid1 command to configure the two-tag termination feature for the sub-interface.

How to configure roaming on an AC
By default, the AC supports intra-AC roaming, which can be implemented as long as the basic WLAN services are configured and the source and destination APs have the same SSID and security policy. To implement inter-AC roaming, you need to configure the master controller, mobility group, and home agent. Note the following points when configuring WLAN roaming: 1. Two APs must use the same SSID and security profile. 2. In the direct forwarding mode, services of a roaming user may be interrupted for a short period because ARP entries of the access device connected to an AP do not age in time. To prevent this problem, run the learn client ip-address enable command in the VAP profile view on the AC to enable STA IP address learning. This function enablesAPs to promptly send gratuitous ARP packets to the access device for ARP entry updates, so that user services will not be interrupted during roaming. By default, STA IP address learning is enabled. 3. A maximum of 16 ACs can be added to a mobility group. An AC can be added only to one mobility group. 4. ACs in the same mobility group must use the same software version, otherwise inter-AC roaming may fail. 5. In dual-link hot standby (HSB) scenarios, roaming between active and standby ACs is not supported. Service interruption may occur if users roam in this scenario.
