Huawei AR530&AR550 Series Industrial Switch Routers Configuration Guide - Ethernet Switching 2 Link Aggregation Configuration Link Aggregation Configuration About This Chapter Link aggregation is a technology that bundles multiple Ethernet links into a logical link to increase bandwidth, improve reliability, and load balance traffic.
Page 45: Introduction To Link Aggregation
Huawei AR530&AR550 Series Industrial Switch Routers Configuration Guide - Ethernet Switching 2 Link Aggregation Configuration 2.1 Introduction to Link Aggregation This section describes definition and purpose of link aggregation. Definition Ethernet link aggregation, also called Eth-Trunk, bundles multiple physical links to form a logical link to increase link bandwidth.
Page 46 Huawei AR530&AR550 Series Industrial Switch Routers Configuration Guide - Ethernet Switching 2 Link Aggregation Configuration Figure 2-1 Eth-Trunk networking Eth-Trunk DeviceA DeviceB The link aggregation interface can be used as a common Ethernet interface to implement routing protocols and other services. Unlike a common Ethernet interface, the link aggregation interface needs to select one or more member interfaces to forward traffic.
Page 47: Forwarding Principle
Huawei AR530&AR550 Series Industrial Switch Routers Configuration Guide - Ethernet Switching 2 Link Aggregation Configuration 2.2.2 Forwarding Principle The Eth-Trunk forwarding table is composed of the following entries: HASH-KEY value The key value is calculated through the hash algorithm based on the MAC address or IP address in a data packet.
Page 48 Huawei AR530&AR550 Series Industrial Switch Routers Configuration Guide - Ethernet Switching 2 Link Aggregation Configuration The Link Aggregation Control Protocol (LACP) can improve fault tolerance of the Eth-Trunk, provide backup, and ensure high reliability of member links. LACP uses a standard negotiation mechanism for a switching device so that the switching device can create and start the aggregated link based on its configuration.
Page 49 Huawei AR530&AR550 Series Industrial Switch Routers Configuration Guide - Ethernet Switching 2 Link Aggregation Configuration If one of M links fails, LACP selects a link from N backup links to replace the faulty link. The actual bandwidth of the aggregated link is still the sum of M links' bandwidth, but the maximum bandwidth of the aggregated link is the sum of the (M+N-1) links' bandwidth.

Huawei AR530&AR550 Series Industrial Switch Routers Configuration Guide - Ethernet Switching 8 SEP Configuration SEP Configuration About This Chapter Smart Ethernet Protection (SEP) is a ring network protocol specially used for the Ethernet link layer. It blocks redundant links to prevent logical loops on a ring network.
Page 289: Introduction To Sep
STP/RSTP/MSTP STP, RSTP, and MSTP are standard protocols for breaking loops on Ethernet networks. They are mature and widely used. Huawei devices running STP, RSTP, or MSTP can communicate with non-Huawei devices. Networks running these protocols converge slowly (in seconds), failing to meet transmission requirements of some real-time services.
