SVF Networking

The parent can be a standalone device, a stack, or a cluster switch system (CSS). An AS can be a standalone device or a stack. If an AS is a stack, see "Restrictions on SVF Roles" in Licensing Requirements and Limitations for SVF.
An SVF network may involve one or multiple of the following networking modes.
A link in the networking may be an Eth-Trunk or a single link.
ASs or APs connecting to an SVF system can be different models.

Table 4-2 SVF networking modes

Networking Mode	Usage Scenario	Processing
1. The parent is directly connected to level-1 ASs.	Small and medium-sized wired campus networks	Parent Create a management VLAN for Layer 2 communication with the client. Configure a DHCP address pool to allocate a management IP address to the client. Create a CAPWAP source interface for communication with the client. Enable the SVF function on the parent. Fabric port between the parent and a level-1 AS Parent-side fabric port: Manually add a physical member port of the level-1 AS to the fabric port. Level-1 AS-side fabric port: Enable the level-1 AS and parent to automatically negotiate a fabric port after the parent-side fabric port is configured. Level-1 AS Change to the client mode. A switch in client mode has no independent configuration file, and you cannot configure services on it directly. All configurations are delivered to client switches from the parent. If a switch has no configuration file and no input on the console port, it performs auto-negotiation with the parent to change its mode. Obtain management VLAN information automatically through the parent.
2. The parent is directly connected to level-1 ASs, and level-1 ASs are directly connected to APs.	Small and medium-sized wired and wireless campus networks	The configurations of the parent, fabric ports connecting the parent and level-1 ASs, and level-1 ASs are the same as those in networking mode 1. The AP configuration is the same as that when APs connect to an access controller (AC) and is not described here.
3. The parent is directly connected to level-1 ASs, and level-1 ASs are directly connected to level-2 ASs.	Medium and large-sized wired campus networks	The configurations of the parent, fabric ports connecting the parent and level-1 ASs, and level-1 ASs are the same as those in networking mode 1. Perform the following configuration on the fabric ports between level-1 ASs and level-2 ASs and on level-2 ASs: Fabric port between a level-1 AS and a level-2 AS Level-1 AS-side fabric port: On the parent, manually add a physical member port of the level-2 AS to the fabric port. Level-2 AS-side fabric port: Enable the level-2 AS and level-1 AS to automatically negotiate a fabric port. Level-2 AS Change to the client mode. A switch in client mode has no independent configuration file, and you cannot configure services on it directly. All configurations are delivered to client switches from the parent. If a switch has no configuration file and no input on the console port, it performs auto-negotiation with the parent to change its mode. Obtain management VLAN information automatically through the parent.
4. The parent is directly connected to level-1 ASs, level-1 ASs are directly connected to level-2 ASs, and level-2 ASs are directly connected to APs.	Medium and large-sized wired and wireless campus networks	The configurations of the parent, fabric ports connecting the parent and level-1 ASs, level-1 ASs, fabric ports connecting level-1 ASs and level-2 ASs, and level-2 ASs are the same as those in networking mode 3. The AP configuration is the same as that when APs connect to an access controller (AC) and is not described here.
5. The parent is connected to level-1ASs across a Layer 2 network.	Networking where there is an intermediate Layer 2 network.	Parent Create a management VLAN for Layer 2 communication with the client. Configure a DHCP address pool to allocate a management IP address to the client. Create a CAPWAP source interface for communication with the client. Enable the SVF function on the parent. Fabric port between the parent and a level-1 AS Parent-side fabric port: Manually add a physical member port of the level-1 AS to the fabric port, and change the fabric port to the indirect connection mode. Level-1 AS-side fabric port: Manually add a physical member port that connects the level-1 AS to the parent. Level-1 AS Manually force the level-1 AS to change to the client mode. Configure a management VLAN on the level-1 AS, which must be consistent with the management VLAN of the parent. AP The AP configuration is the same as that when APs connect to an access controller (AC) and is not described here.
