Example for Configuring SVF to Deploy a Wired Campus Network Access Layer (S12700 as the Parent)

Networking Requirements

A new wired campus network has many access devices. The widely distributed access devices complicate management and configuration of the access layer. Unified management and configuration of access devices are required to reduce the management cost.

As shown in Figure 1, two aggregation switches set up a CSS and function as the parent to connect to multiple ASs.

In this example, the S12700 functions as the parent, the S5720-28P-SI-AC functions as a level-1 AS, and the S5720-28TP-LI-AC functions as a level-2 AS.

Figure 1 Configuring a wired campus network access layer

Configuration Roadmap

The configuration roadmap is as follows:

Configure the parent as a CSS to ensure high reliability of the SVF system.
Enable the SVF function on the parent.
Configure AS access parameters, including the AS name, authentication mode, and fabric ports that connect the parent to level-1 ASs and level-1 ASs to level-2 ASs.
Connect the parent to level-1 ASs and level-1 ASs to level-2 ASs using cables.
Configure service profiles and bind them to ASs.

Procedure

Configure two switches in the parent to set up a CSS.

# Configure the management VLAN in the SVF system and enable the SVF function on the parent.

Configure AS access parameters.

# (Optional) Configure a name for each AS.

If you do not perform this step, the system will generate AS device information when ASs connect to the SVF system. An AS name is in the format of system default name-system MAC address.
If you need to perform this step, ensure that the configured model and mac-address parameters are consistent with the actual AS information. The value of mac-address must be the AS management MAC address or system MAC address. To view the AS management MAC address, run the display as access configuration command on the AS. If the management MAC displays --, the value of mac-address is the system MAC address. If the configured parameters are inconsistent with the actual AS information, the AS cannot go online.

The configurations of fabric ports 2 and 3 that connect the parent to AS 2 and AS 3 respectively are similar to the configuration of fabric port 1, and are not mentioned here.

# Configure ASs to be authenticated using a whitelist when they connect to the SVF system.

To view the AS management MAC address, run the display as access configuration command on the AS. If the management MAC displays --, the MAC address configured in the whitelist is the AS system MAC address. Otherwise, the MAC address configured in the whitelist is the AS management MAC address.

Connect the parent to level-1 ASs and level-1 ASs to level-2 ASs using cables.
# Run the reset saved-configuration command to clear the configurations of ASs, restart the ASs, and then connect the parent to level-1 ASs and level-1 ASs to level-2 ASs using cables. Subsequently, an SVF system is set up.
- Before restarting an AS, check whether the port that connects this AS to the parent is a downlink port. You can run the display port connection-type access all command on this AS to view all downlink ports on it. If this port is a downlink port, run the uni-mng up-direction fabric-port command on this AS to configure this port as an uplink port before restarting this AS. Otherwise, this AS cannot go online.
- Before connecting an AS to the parent, ensure that the AS has no configuration file and no input on the console port.
# After connecting cables, run the display as all command to check whether ASs have connected to the SVF system.
