• SNMP read and write communities have been configured for devices. In addition, the devices have been added to eSight, and can successfully communicate with eSight.
• SNMP and Telnet parameters have been configured on eSight.
• The LLDP protocol has been enabled on SVF-capable devices.

Networking Requirements

Company M has constructed a wired campus network on which many access devices are deployed sparsely. It is difficult to manage and configure these access devices. The network administrator Jack requires that he can uniformly manage and configure the access devices to reduce management costs.

As shown in Figure 4-44, two switches at the aggregation layer form a cluster and function as the parent devices to connect to multiple access switches (ASs).

In this example, the S12708, S5700-28P-LI, and S2750-28TP-EI are used as the parent, level-1 AS, and level-2 AS, respectively. The eSight software version is V300R009C00.

Configuration Roadmap

The configuration roadmap is as follows:

1. Configure CSS on the parent devices to ensure high reliability of the super virtual fabric (SVF) system.
2. Configure SVF system capabilities.
   1. Create an SVF enabling template to enable SVF on the parent and configure the SVF client management IP address pool, file server, and forwarding mode.
   2. Create an AS predeployment template to predeploy ASs on the SVF parent before powering on them and add the ASs to a whitelist. After the ASs are powered on, the SVF parent permits the ASs to access the SVF network.
   3. Create a level-1 AS fabric port template to set parameters for the fabric ports that connect the SVF parent to level-1 ASs.
   4. Create a level-2 AS fabric port template to set parameters for the fabric ports that connect level-1 ASs to level-2 ASs.
   5. Create a system configuration matrix to deploy the template instances to the SVF parent.
3. 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.
4. Configure SVF service capabilities.
   1. Create port groups.
   2. Create user interface VLAN templates to set pass VLANs for user-side ports.
   3. Create a user interface service template to set network security parameters for user-side ports.
   4. Create a service configuration matrix to deploy the template instances to the port groups.

Data Plan

Procedure

1. Set up a cluster between the two switches that function as the parents. For details, see "CSS Configuration" in the S12700 Configuration Guide - Device Management of the specific product version.

   S5720HI, S5730HI, S6720HI, S6720EI, or S6720S-EI switches can also set up a stack and act as the parent. If you use a stack of S6720EI or S6720S-EI switches as the parent, run the as-mode disable command to configure the stack to work in parent mode. For other stack configuration instructions and precautions, see "Stack Configuration" in the S2700, S5700, and S6720 Configuration Guide - Device Management.

2. Create a template instance and enable SVF on the parent device.
