Application of the Huawei S6700 Switch on a Large-scale Enterprise Campus Network

This section describes the application of the Huawei S6700 Switch on a large-scale enterprise campus network.

As shown in the below picture, the Huawei S6700 Switch is deployed at the aggregation layer of a large-scale enterprise campus network, helping you built a highly reliable, scalable, and manageable enterprise campus network.

On an enterprise network or campus network, the S6700s connect to access switches through 100M/1000M interfaces, provide high performance and large switching capacity, and connect to core switches through 10GE optical interfaces. The network provides 10 Gbit/s rate for the backbone layer and 100 Mbit/s access rate for terminals, meeting requirements for high bandwidth and multi-service.

The Huawei S6700 Switch provides SEP and RRPP to implement millisecond-level protection switching. S6700s form a stack system by using iStack technology to implement the distributed forwarding structure and fast fault recovery. The stack system increases the number of user interfaces and improves packet processing capability. The iStack-enabled S6700s can be managed in a uniform manner to facilitate network management and maintenance.

What’s the Power Supply Configuration of Huawei S6700 Switch

On a S6700-EI switch, one or two power modules can be configured.

When two power modules are used, they work in 1+1 backup mode to provide power for the device. In the versions earlier than V200R005C00, the AC and DC power modules cannot be configured on the same device, while in V200R005C00 and later versions, they can be configured on the same device.

Figure 1

shows the power supply connections of dual DC power modules. After DC power is transmitted to the PWR module, the PWR module provides -53 V output voltage, and the motherboard provides power for the entire device.

Figure 2 shows the power supply connections of dual AC power modules. After AC power is transmitted to the PWR module, the PWR module provides -53 V output voltage, and the motherboard provides power for the entire device.

Multicast Network Management

Involved Network Elements

An IPv4 multicast network consists of the following network elements:

Multicast source: sends multicast data to receiver hosts. For example, a video server is a multicast source.

Device running IPv4 Protocol Independent Multicast (PIM): uses the PIM (IPv4) protocol to generate and maintain multicast routing entries and forwards multicast data based on multicast routing entries. On an IPv4 multicast network, all Layer 3 devices must run PIM (IPv4); otherwise, multicast forwarding paths cannot be established.

Device running the Multicast Source Discovery Protocol (MSDP): forwards multicast data from one PIM network to another. For example, if multicast data needs to be transmitted between two autonomous systems (ASs), the devices at the border of the ASs must run the MSDP protocol.

Device running multicast VPN: enables multicast data of a private network to be transmitted over a public network. Such devices are used on VPN networks. For example, if two sites of a VPN network need to exchange multicast data across a public network, multicast VPN needs to be configured on the PE devices.

IGMP querier: exchanges IGMP messages with receiver hosts to create and maintain group memberships. On a multicast network, Layer 3 devices connected to network segments of receivers must run the IGMP protocol or be configured with static IGMP groups. Otherwise, upstream PIM devices cannot know the multicast groups that users want to join, and therefore cannot establish multicast forwarding paths.

Device running IGMP snooping: listens on IGMP messages exchanged between upstream Layer 3 multicast devices and receiver hosts to create and maintain Layer 2 multicast forwarding entries, which are used for accurate multicast data forwarding on a Layer 2 network. To prevent broadcasting of multicast packets on a Layer 2 network and conserve network bandwidth, it is recommended that you configure IGMP snooping on Layer 2 devices.

Receiver: multicast user that receives multicast data. A receiver can be a PC, a set top box, or any device with multicast client installed.

An IPv6 multicast network consists of the following network elements:

Multicast source: sends multicast data to receiver hosts. For example, a video server is a multicast source.

Device running IPv6 Protocol Independent Multicast (PIM): uses the PIM (IPv6) protocol to generate and maintain multicast routing entries and forwards multicast data based on multicast routing entries. On an IPv6 multicast network, all Layer 3 devices must run PIM (IPv6); otherwise, multicast forwarding paths cannot be established.

MLD querier: exchanges MLD messages with receiver hosts to create and maintain group memberships. On a multicast network, Layer 3 devices connected to network segments of receivers must run the MLD protocol or be configured with static MLD groups. Otherwise, upstream PIM devices cannot know the multicast groups that users want to join, and therefore cannot establish multicast forwarding paths.

Device running MLD snooping: listens on MLD messages exchanged between upstream Layer 3 multicast devices and receiver hosts to create and maintain Layer 2 multicast forwarding entries, which are used for accurate multicast data forwarding on a Layer 2 network. To prevent broadcasting of multicast packets on a Layer 2 network and conserve network bandwidth, it is recommended that you configure MLD snooping on Layer 2 devices.

Receiver: multicast user that receives multicast data. A receiver can be a PC, a set top box, or any device with multicast client installed.

Multicast network management is a network management feature that can be configured on a device running a multicast protocol.
