SVF Configuration Management
This section describes the SVF configuration management feature, including the definition, benefits, functions, principles, and key indicators of the feature.
Definition
eSight provides unified device management, unified user management, and service configuration management for SVF.
Benefits
Compared with the traditional access layer networking, the SVF networking has the following advantages:
- Unified device management: SVF virtualizes aggregation and access devices into one logical device and allows aggregation devices to manage and configure access devices.
- Unified configuration: SVF implements batch configuration of access devices based on profiles, avoiding configuring access devices one by one.
- Unified user management: SVF manages wired and wireless access users in a unified manner.
Functions
Super virtual fabric (SVF) is a vertical virtualization technology that virtualizes devices at the core, aggregation, and access layers into one device for centralized device management. This reduces the number of managed devices, simplifies operation and maintenance (O&M) scenarios, and improves O&M efficiency.
Administrators can manage the SVF capabilities of agile switches and CE switches to implement device monitoring, user management, and service deployment on SVF networks.
Unified Device Monitoring
eSight treats an SVF network as one device to uniformly manage and monitor wired and wireless devices on the network.
An SVF network is displayed as one device in the topology and panel, which facilitates centralized management of device running information and alarms on the entire network. The information includes the running status of parent and client devices and connection status of links between SVF members.
Unified User Management
Administrators can uniformly manage wired and wireless users connected to SVF networks. They can also view the ASs to which wired users connect and the APs to which wireless users connect, and perform fault diagnosis for wireless users.
SVF Configuration Management
- Template Management
Administrators can create, modify, and delete SVF service templates.
- Service Configuration
eSight provides three configuration matrices to instruct users to quickly deploy SVF services, the matrices are SVF system configuration matrix, SVF port configuration matrix, and SVF maintenance and configuration matrix.
Principle
Agile Switch SVF Networking
SVF is a vertical stack management technology developed by Huawei. It combines horizontal stacking technologies CSS/CSS2 and iStack and link aggregation group (LAG), and virtualizes devices on the entire network into one switch. The SVF-Parent serves as the management node for the virtual switch, and the access switches (ASs) and wireless access points (APs) serve as SVF-Clients. The SVF-Parent and SVF-Clients form an SVF management system. The SVF-Parent has Ethernet Network Processor (ENP) cards installed, so it can provide the wired and wireless convergence function, making the network easy to deploy, manage, and maintain.
CE Switch SVF Networking
The SVF solution for CE switches uses the vertical virtualization technology to virtualize multiple switches into one switch. As an interface expansion technology, SVF implements vertical extension of heterogeneous switches and virtualizes multiple leaf switches into cards of the spine switch, facilitating device management. Leaf switches are managed as cards of the spine switch. When users configure leaf switches, they are displayed as interfaces on the spine switch.
The system is composed of two types of devices: spine switch and leaf switch.
Spine switch is the core of the stack system and responsible for control and forwarding of the entire system. The spine switch can be a single switch or multiple switches in a stack.
Leaf switch serves as a board of the spine switch and only forwards packets locally. The control plane is on the spine switch.
