First of all, before making any bridging device, you need to have a local virtual network card, even if there is no virtual machine, it can be done. If there is no local virtual network card, you can refer to the following link to complete

When the local loopback network card is added, we officially enter the bridge device process
1. Run the AC equipment
2. The small cloud setting port of topology ensp
The purpose of adding an interface is also to connect with a cable in the next step to select the interface, otherwise it is in a state of not moving
3. Connect the device
4. Configure AC interface IP
Since the interface mode of the AC defaults to Layer 2, it is necessary to configure the VLAN to enter the Layer 3 interface configuration.
If no vlan is configured on the interface, the default interface is to encapsulate the label of the default vlan1, so the layer-3 interface must enter vlanif1, and the configured IP must be in the same address segment as the virtual loopback network card just added, otherwise you will not be able to log in
The most important step is to enable the HTTP function of AC
5. Browser login to AC
Logging in for the first time will ask you to reset your password
After clicking confirm, you will be prompted to log in again
Ok, the following can be configured normally
