An AP can be restarted using command lines on the AC, restarted manually after login, by holding down the default button on the AP or powering off and then powering on the AP. What are their differences and application scenarios

1

- Run the ap-reset command in the WLAN view of the AC to restart a specified AP or restart APs in a batch. This command applies only to online APs.

What are the differences between AP restart modes and what are their application scenarios
You can restart an AP in the following ways: run the reset command on the AC, log in to the AP and restart it, hold down the RESET button on the AP, and power off and on the AP. The differences and application scenarios of these restart modes are as follows: - Run the reset command on the AC: Run the ap-reset { all | id ap-id | ap-type { type ap-type | type-id type-id } } command in the WLAN view to restart a specified AP or APs in batches. This command applies only to online APs. - Log in to the AP and restart it: Log in to the AP and run the reboot command in the user view to restart the AP. You can restart an AP using this method only after you log in to the AP using Telnet or through the console port. This method is used to restart APs that are not online on the AC. You can connect a PC to the wired interface of the AP and log in to the AP using Telnet. - Hold down the RESET button on the AP: Using this method, you can restart an AP without the need to get the AP online or log in to the AP. - Power off and on the AP: If the AP uses PoE power supply, run the undo poe enable and poe enable commands in the interface view of the power sourcing equipment (PSE) to restart the AP.

Will the AP ID be changed after an AC restart
No.

Common operations for managing WLAN APs
Common operations for managing APs 1. Log in to an AC and change an AP's login user name and password. - V200R005: [HUAWEI] wlan [HUAWEI-wlan-view] wlan ap username huawei password cipher Enter the password (plain-text password of 8-32 characters or cipher-text password of 32 or 56 characters): Confirm password: [HUAWEI-wlan-view] commit ap 1 //Run the display ap command to obtain the AP ID if you forget the AP's login password. Warning: Committing configuration may cause service interruption, continue?[Y/N] :y To restore the default user name and password, run the undo wlan ap username command. By default, the user name is admin and password is admin@huawei.com. - V200R006: [HUAWEI] wlan [HUAWEI-wlan-view] ap-reset ap-id 1 Enter the password (plain-text password of 8-32 characters or cipher-text password of 48 or 68 characters): Confirm password: To restore the default user name and password, run the undo ap username command. By default, the user name is admin and password is admin@huawei.com. 2. Restart an AP. - V200R005: [HUAWEI] wlan [HUAWEI-wlan-view] ap-reset id 1 Warning: Reset AP, continue?[Y/N]:y Operation on the web platform: Choose Configuration > AP Management > AP Information. Select an AP and click Restart. - V200R006: [HUAWEI] wlan [HUAWEI-wlan-view] ap-reset ap-id 1 Warning: Reset AP, continue?[Y/N]:y Operation on the web platform: Choose Maintenance > AP Maintenance > AP Restart. Select an AP and click Restart. 3. Restore factory settings. - V200R005: Run the ap-manufacturer-config id ap-id command to restore factory settings of an AP. - V200R005: Run the ap manufacturer-config { ap-name ap-name | ap-mac ap-mac | ap-id ap-id } command to restore factory settings of an AP. 4. Change the AP name. - V200R005: [HUAWEI-wlan-view] ap id 1 [HUAWEI-wlan-ap-1] ap-sysname ap_01 Operation on the web platform: Choose Configuration > AP Management > AP Information. Click the icon of a specific AP and change the AP name. - V200R006: [HUAWEI-wlan-view] ap-rename ap-name N1-2 new-name N2-2 Operation on the web platform: Choose Configuration > AP Configuration > AP Information. Click the name of a specific AP and change the AP name. 5. Delete an AP. - V200R005: [HUAWEI-wlan-view] undo ap id xx Operation on the web platform: Choose Configuration > AP Management > AP Information. Select an AP and click Delete. If ACs work in active/standby mode, you are advised to disconnect the AP and delete the AP from both the active and standby ACs. - V200R006: [AC6605-wlan-view] undo ap-id xx Operation on the web platform: Choose Configuration > AP Configuration > AP Information. Select an AP and click Delete. If ACs work in active/standby mode, you are advised to disconnect the AP and delete the AP from both the active and standby ACs. 6. IP addresses of APs cannot be modified on an AC.

Does the configuration need to be committed after an AP is powered off
After restarting and going online on an AC, a Fit AP automatically obtains configuration from the AC. You do not need to deliver the configuration again or reconfigure the AP.

Whether the AR router used as the AC supports PoE power supply for APs
PoE technology is used on the wired Ethernet and is most widely used on LANs. PoE allows power to be transmitted to terminals through data transmission lines or idle lines.This technology provides power over a 10Base-T, 100Base-TX, or 1000Base-T Ethernet network, spanning a distance of up to 100 m. PoE can be used to effectively provide centralized power for terminals such as IP phones, Access Points (APs), chargers of portable devices, POS machines, cameras, and data collection devices. Whether the AR can supply power to APs depends on whether the AR supports the PoE function, but does not depend on whether the AR functions as an AC. AR series routers that support PoE are as follows: Device models: AR207V-P, AR201VW-P; supported interfaces: Ethernet0/0/0 to Ethernet0/0/7 Device models: AR151W-P; supported interfaces: Ethernet0/0/0 to Ethernet0/0/4 Device models: AR1220V, AR1220W, and AR1220VW; supported interfaces: Ethernet0/0/4 to Ethernet0/0/7 All GE electrical interfaces on the 4ES2GP-S card support the PoE function. However, you need to install the 100W AC PoE power module on the device to enable the PoE function.
