Configuration Procedure
This section only describes how to configure agile features, and does not describe other basic configurations, such as routing connectivity.
SVF Configuration Procedure
Configure ASs to connect to the parent.
- Configure the two switches in the parent to set up a CSS. For details, see the product documents.
Log in to the CSS and enable the SVF function.
<HUAWEI> system-view [HUAWEI] vlan batch 11 [HUAWEI] dhcp enable //Enable the DHCP server function to allow an AS to obtain an IP address from the parent. [HUAWEI] interface vlanif 11 [HUAWEI-Vlanif11] ip address 192.168.11.1 24 [HUAWEI-Vlanif11] dhcp select interface [HUAWEI-Vlanif11] dhcp server option 43 ip-address 192.168.11.1 //Configure the parent to send the IP address to an AS so that the AS can set up a CAPWAP link with the specified IP address. [HUAWEI-Vlanif11] quit [HUAWEI] capwap source interface vlanif 11 //Set up a CAPWAP link between the parent and the AS. [HUAWEI] authentication unified-mode //Change the network admission control (NAC) configuration mode to the united mode. [HUAWEI] stp mode rstp //Set the working mode to STP or RSTP when enabling the SVF function. [HUAWEI] uni-mng //Enable the SVF function and enter the uni-mng view. Warning: This operation will enable the uni-mng mode and disconnect all ASs. STP calculation may be triggered and service traffic will be affected. Continue?[Y/N]: y
When enabling the SVF function, ensure that the current and next startup NAC configuration modes are the unified mode.
You can run the display authentication mode command to check whether the current and next startup NAC configuration modes are the unified mode. If not, set the modes to the unified mode.
After the traditional and unified modes are switched, restart the device to make the configuration take effect. By default, the NAC configuration mode is unified mode.
Configure access parameters for ASs.
# Configure ASs' names, and specify the device models and management MAC addresses for the ASs.

- Clear the configurations
of ASs, restart the ASs, and then connect the ASs to the parent using
cables. Subsequently, an SVF system is set up.
Before connecting an AS to the parent, ensure that the AS has no configuration file or input on the console port.
# Clear the configurations of ASs and restart the ASs. (This process takes 5 minutes. During the process, ensure that the AS has no input on the console port. If the ASs are unconfigured, you can directly connect the ASs to the parent with no need to restart the ASs.)
<HUAWEI> reset saved-configuration Warning: The action will delete the saved configuration in the device. The configuration will be erased to reconfigure. Continue? [Y/N]:y# After connecting the cables, run the display as all command to check whether all ASs have connected to the SVF system successfully.

[HUAWEI] group-policy controller 192.168.2.31 password Huawei@123
Perform the following configurations on the Agile Controller.
Screenshots on the Agile Controller are not provided here. For details, see the Agile Controller product documents.
- Create user accounts in source security groups. For example, you can configure user names, passwords, and departments for common guests, undergraduates, postgraduates, and teachers.
- Configure RADIUS, Portal, and XMPP parameters, and add the core switch to ensure that the S series switches can communicate with the Agile Controller.
- Configure source security groups and destination security groups to indicate users and resources respectively. For example, the IP address of the public resource server is 10.10.1.1/32.
- Use fast authorization to authorize a source security group to the corresponding department. Users are mapped to the source security group after being authenticated.
- Configure access control policies and specify whether users in a source security group are permitted to access a destination security group. Deploy the access control policies on all devices on the network. For example, common guests can only access the public resources, and cannot access the education management system and internal FTP resources.
| Source Security Group (User) | Destination Security Group (Resource) | Access Control Policy |
|---|---|---|
| Common guest | Public resources (bound IP address: 10.10.1.1/32) | Permit |
| Education management system (bound IP address 10.10.2.1/32) | Forbid | |
| FTP resources (bound IP address: 10.10.3.1/32) | Forbid | |

| FTP resources (bound IP address: 10.10.3.1/32) | Permit |
Wired and Wireless Convergence Configuration Procedure
After wired and wireless convergence is configured on an agile switch, you do not need to individually configure the switch and independent AC or ACU2; you can perform configurations on the switch directly.
Configure the S12708 to function as a DHCP server to assign IP addresses to PCs and STAs. The S12708 assigns IP addresses to APs through SVF. You do not need to configure the S12708 to assign IP addresses to APs. The following example describes how the S12708 assigns IP addresses to the PCs and STAs in teaching area 1.
# Configure the S12708 to assign an IP address to PC_1 from the global address pool.

iPCA Configuration Procedure
iPCA can be performed to detect packet loss on agile switches and between agile switches. If you want to detect packet loss between the main campus and branch campus networks, agile switches need to be deployed on both networks.
Configure the packet loss measurement function for a device.
Enable iPCA on each device to implement packet loss measurement so that you can know packet loss in a timely manner. Configure the packet loss alarm on each device.
[HUAWEI] iplpm global loss-measure alarm enable //Enable the packet loss alarm and clear alarm on a device. [HUAWEI] iplpm global loss-measure enable //Enable the packet loss measurement
- Run the display iplpm
loss-measure statistics global command to check the packet loss
measurement results on a device. You can check the values of Loss
Packets and LossRatio to know whether packet loss occurs
on a device.
