In point-to-multipoint WDS networking, how to ensure that other bridge nodes work properly if one AP is faulty or powered off

14

In point-to-multipoint WDS networking, if the root or middle node is faulty, links between this node and downstream nodes are disconnected, leading to network breakdown. Limited by frequency resources, Huawei network bridge solution does not use the redundancy mode. It is recommended that mains be used or the UPS be added to provide power for APs.
APs enabled with Mesh functions can set up radio connections, and Mesh links can work as backup of each other. If a neighbor node of an MP fails, the MP can select an optimal link from candidate links to continue data transmission.

Is redundancy used or a proximate AP selected as a repeater AP to ensure that other WDS bridges work properly when the middle AP is faulty or powered off
When the root or middle node is faulty, uplinks between this node and downstream nodes are disconnected. Limited by frequency resources, Huawei network bridge solution does not use the redundancy mode. It is recommended that mains be used or the UPS be added to provide power for the AP. NOTE: Starting from V200R003C00, the AP can support Mesh functions. APs enabled with Mesh functions can set up radio connections. Mesh links can work as backup of each other. If a neighbor node of an MP fails, the MP can select an optimal link from candidate links to continue data transmission.

Does a WDS network support bridging from cameras
In WDS networking, APs are connected through WDS links, so that remote APs can go online on the AC wirelessly. After the APs go online successfully, the AC can deliver configurations to them. If you need to connect a camera wirelessly, ensure that the camera supports wireless access. You must configure WLAN coverage services for the AP, so that the wireless camera can access the WLAN like laptops or mobile phones. Do not configure the WDS service because it is used to deploy wireless bridging between APs.

Does the clock work properly after an S series fixed switch is powered off
If some models and versions of S series fixed switches (except S1700 switches) are powered off, the clock can recover. For some other models and versions, the clock cannot recover. For details, see the following: - For switches running a version earlier than V100R006: The system clock of a switch is implemented by the software. The system saves the system clock if the switch is powered off and restarted manually. If the switch is powered off due to a power failure, the system time is restored to the factory setting. - For switches running V100R006 or V200R001: The system clock of the S3700HI, S5700HI, or S6700 is implemented by the hardware. The system obtains the clock from the hardware if the switch is powered off and restarted manually. System clocks of other models are implemented by the software. The system saves the system clock if a switch is powered off and restarted manually. If the switch is powered off due to a power failure, the system time is restored to the factory setting. - For switches running V200R002 and V200R003: The system clock of the S5700HI or S6700 is implemented by the hardware. The system obtains the clock from the hardware if the switch is powered off and restarted manually. System clocks of other models are implemented by the software. The system saves the system clock if the switch is powered off and restarted manually. If the switch is powered off due to a power failure, the system time is restored to the factory setting. - For switches running V200R005 or a later version: The system clock of the S5700 or S6700 is implemented by the hardware. The system obtains the clock from the hardware if the switch is powered off and restarted manually. System clocks of other models are implemented by the software. The system saves the system clock if a switch is powered off and restarted manually. If the switch is powered off due to a power failure, the system time is restored to the factory setting.

Cache flushing time supported by a single BBU of OceanStor V3 after the system is powered off
The BBU can provide power for eight minutes. OceanStor V3 BBUs are in 1+1 backup mode. The cache has enough time to flush dirty data to data coffer disks.
