How Can I Select a Configuration File?

1

ere are two methods for system configuration: You can import a configuration file or manually enter configuration information.
? Importing a configuration file
Subsequent configuration information will be automatically inputted as required based on the configuration file, simplifying the configuration process and reducing configuration time. This method is commonly used when the storage system is deployed for the second time and the configuration file of the first deployment must be used.
? Manually entering configuration information
All configuration information must be manually entered. This method is used for initial deployment.

How can I configure selective QinQ on CE switches
Selective QinQ is also called VLAN stacking. It adds different outer tags to the frames received on a Layer 2 QinQ interface according to different inner tags or the frames matching traffic classification rules. This function enables refined management of users and services. # Configure selective QinQ on 10GE1/0/1 and add VLAN 100 in the outer tag to the tagged frames with the VLAN range of 10 to 13. 
system-view
[~HUAWEI] vlan batch 10 to 13 100
[*HUAWEI] interface 10ge 1/0/1
[*HUAWEI-10GE1/0/1] port link-type hybrid
[*HUAWEI-10GE1/0/1] port hybrid untagged vlan 100 [*HUAWEI-10GE1/0/1] port vlan-stacking vlan 10 to 13 stack-vlan 100
[*HUAWEI-10GE1/0/1] commit
Description: - Selective QinQ can be enabled only on hybrid and trunk interfaces and applied to incoming packets. - The outer VLAN ID must exist and the interface must be added to the stack VLAN in untagged mode. - If the port vlan-stacking command with VLAN ranges specified has been executed for three or more times and VLAN ranges are combined twice at least, the configuration of each command must be committed. Otherwise, packets may be lost. For example, when port vlan-stacking vlan 30 to 60 stack-vlan 100, port vlan-stacking vlan 20 to 30 stack-vlan 100, and port vlan-stacking vlan 60 to 70 stack-vlan 100 commands are executed, VLAN ranges 20 to 60 and 20 to 70 are combined twice. Therefore, commit each command configuration.

How to select antennas for APs
Antennas receive and send radio signals. Select antennas for APS by referring to HUAWEI Access Points Antenna Quick Start. Contact Huawei local offices to purchase antennas. Antennas from other vendors are not recommended for working with Huawei APs. Consider the following points when selecting antennas: 1. Usage scenario and purpose Indoor antennas are generally used to provide signal coverage in indoor scenarios while outdoor antennas are used to provide signal coverage and bridging backhaul in outdoor scenarios. 2. Local standards and regulations The transmit power and maximum gain of antennas must strictly comply with local standards and regulations. 3. Shape and distance of the coverage or backhaul area - Coverage: Directional antennas are recommended in long and narrow areas while omnidirectional antennas are recommended in round and square areas. - Backhaul: Directional antennas are usually used. If the backhaul distance is long, use high-gain antennas; if backhaul targets are concentrated, use small-angle antennas. 4. Signal transmission band (2.4 GHz/5 GHz) - Coverage: To provide 2.4 GHz and 5 GHz signal coverage, use 2.4Gand 5G antennas in the same area or use dual-band antennas. - Backhaul: Only 5 GHz antennas are used for backhaul.

OLP configuration method selection
1. Multiplexed signals enter the working and protection routes after being separated on the OLP board at the rear of the FIU board. This type of OLP protection is applicable to the scenarios where the optical cable of the working route is consistent with that of the protection route, and the line distance and attenuation are almost the same (which is called uniform route). Configuration principles: a. If multi-section protection is configured on lines, and the duration of each protection switching caused by a fiber cut must be shorter than 50 ms, verify that the residual dispersion in the system in different active and standby fiber combination scenarios meets the dispersion window requirements. For example, for the network shown in Figure 1, the following scenarios need to be verified: active 1 + active 2 + active 3, standby 1 + standby 2 + standby 3, active 1 + active 2 + standby 3, active 1 + standby
