l 定时器的值有可能不同，但这些设备都将以相邻端口的 LeaveAll 定时 器的最小值为周期来发送 LeaveAll 消息，并且，下次重启后，各个端口的 LeaveAll 定时器的值都 将在一定范围内随机变动。
4. MRP协议报文封装格式 图1-1 MRP 协议报文封装格式
2. MRP消息 MRP 应用实体之间的信息交换借助于传递各种消息来完成，主要包括 Join 消息、New 消息、Leave 消息和 LeaveAll 消息，它们通过互相配合来确保信息的注册或注销。由于 MVRP 基于 MRP 实现， 因此，MVRP 也是通过 MRP 消息进行信息交互的。 (1) Join 消息
1.1.1 MRP简介
与 GARP 提供的机制不同，MRP 支持在基于 MSTI（Multiple Spanning Tree Instance，多生成树 实例）的基础上，用于协助同一局域网内各成员之间声明、传播和注册某种信息（如 VLAN）。 1. MRP实现机制 设备上每一个参与协议的端口都可以视为一个应用实体，当 MRP 应用（如 MVRP）在端口上启动 之后，该端口就可视为一个 MRP 应用实体。 通过MRP机制，一个MRP应用实体上的配置信息会迅速传遍整个局域网。如 图 1-1 所示，MRP应 用实体通过发送两种协议报文：声明或回收声明，来通知其它MRP应用实体来注册或注销自己的属 性信息，并根据其它MRP实体发来的声明或回收声明来注册或注销对方的属性信息。 图1-1 MRP 实现机制示意图
Periodic 定时器允许用户通过命令行开启或关闭。如果关闭 Periodic 定时器，则不再周期发送 MRP 消息。
(2) Join 定时器 Join 定时器用来控制消息的发送。为了保证消息能够可靠地传输到其它实体，MRP 应用实体在发 出 Join 消息后将等待一个 Join 定时器的时间间隔。如果在该定时器超时前收到了其它实体发来的 JoinIn 消息，便不再重发该 Join 消息。在该定时器超时后，如果此时 Periodic 定时器也超时，它将 重发一次该 Join 消息；否则不发送该 Join 消息。 (3) Leave 定时器 Leave 定时器用来控制属性的注销。当 MRP 应用实体希望其它实体注销自己的某属性信息时会发 送 Leave 消息，收到该消息的实体将启动 Leave 定时器，只有在该定时器超时前没有收到该属性信 息的 Join 消息，该属性信息才会被注销。 (4) LeaveAll 定时器

文件修改记录：20130812 v0.1 创建文件。

20130827 v0.2 修正2.8中四上行的描述错误，增加四框环形堆叠的转发优先级说明。

1 四框堆叠的软件版本在2012年及以后的软件版本均能够支持四框堆叠。

2 四框堆叠的注意事项因为四框堆叠比较复杂，所以在使用前这些注意事项必须保证，那么这里主要描述在使用四框堆叠的各种注意事项及原因：2.1 每机框必须双主控为了保障堆叠的可靠性，每个机框必须双主控，规避单个主控硬件故障造成堆叠分裂的风险。

2.2 端口可任意使用S12500的四框堆叠与两框堆叠一样，任意板卡的任意端口均可以用于堆叠。

没有板卡限制，且同芯片的单端口在作为堆叠口之后，其他端口仍然可以作为业务端口，没有任何限制。

2.3 S12518和S12508之间可以堆叠S12518和S12508可以互相堆叠，虽然产品形态不同，但是没有影响。

2.4 堆叠链路必须跨板冗余在网络规划时，必须保证堆叠链路是跨板冗余的，这是为了避免当小概率的单板硬件故障发生时，仍然有可用的堆叠链路，避免因为单板故障造成整个堆叠的分裂。

两框堆叠必须如此，四框堆叠更加需要如此设计。

2.5 堆叠链路速率必须相同堆叠链路的速率必须完全相同，否则在有跨框流量时，多条堆叠链路会进行负载分担，如果不同的带宽，以5G跨框流量为例，则万兆口通过2.5G流量没问题，但千兆口也会分担到2.5G流量，会出现严重丢包。

堆叠口可以使用千兆、万兆、40GE、100GE，任意板卡均可使用。

2.6 跨框流量需要规划好堆叠口并非能无限扩展，在堆叠的端口组内最多允许12个Active的端口，那么实际上跨框的流量需要经过准确规划。

如果上万兆板，那么跨框流量不要超过10G*12=120G，同理于40G板和100G板。

一般情况下都会本地优先转发，跨框流量很小，举例来说，只有在1号框进但流量的出端口在其他框上时，才会出现从1号框到其他框的流量。

2.7 MAD链路必须正常部署不管是两框堆叠，还是四框堆叠，在正常部署前，必须规划MAD链路并部署，否则出现多活的时候，会是整个网络的灾难。

It improves availability and performance eliminating single-point of failures, and ensure service continuity Distribution - Multi-chassis link aggregation to enable loadsharing and backup over multiple uplinks, improving redundancy and link utilizationEasy Management - A single IP address to manage the whole IRF fabric, which simplifies device and topology management, improving operating efficiency, and lowering network maintenance costTVirtualization technologies - IRF2Virtualization technologies - IRF3Features Advanced CLOS+ multi-grade multi-plane switching architecture•••••••••••••CLOS+ multi-grade multi-plane architecture, midplane free design, providing continuous bandwidth upgrade capability Supports industry first 48-port 40GE/ 100GE interfaces and can meet the existing and future application requirements of data centers•Adopts independent switching fabric modules and MPU engines to improve device availability and ensure bandwidth expansion••Increased I/O ports and centralized maintenance and managementReduced network management nodes Simplified cable deployment Data plane virtualizationIRF2 can virtualize up to four S12500 switches into one logical IRF fabric. IRF2 delivers the following benefits:IRF3 virtualizes core and access switches into one logical device. IRF3 delivers the following benefits:OverviewIndependent control engine - Uses a powerful CPU system that can efficiently process protocol and control packets, providing refined control for protocol packets and comprehensive protection against protocol packet attacks Independent detection engine - Provides highly reliable Fast Fault Detection and Restoration (FFDR) such as BFD and OAM, which can interact with protocols on the control plane toimplement millisecond-level failover and convergence, ensuring service continuityIndependent maintenance engine - Uses an intelligent Embedded Maintenance Subsystem (EMS), a CPU system that provides smart power management, including sequential power-on and power-off and device status check. Sequential power-on and power-off reduces power impulse, electromagnetic radiation, power consumption, and extends the device lifespan•••••••••••TRILL/SPB - Designed for building large flat Layer 2 networks for data centers to accommodate more servers. TRILL or SPB integrates the simplicity and flexibility of Layer 2 with the stability, scalability, and high performance of Layer 3EVI - EVI is a MAC-in-IP technology that provides Layer 2connectivity between distant Layer 2 network sites across an IP routed network. It is used for connecting geographically dispersed sites of a virtualized large-scale data center that requires Layer 2 adjacencyFCOE - Integrates heterogeneous LANs and storage networks in data centers. FCOE and CEE integrate data, computing, and storage networks in data centers, reducing the costs for building and expanding data centersVXLAN (Virtual Extensible LAN) —VXLAN uses a MAC-in-UDP encapsulation method where the original Layer 2 package is added with a VXLAN header, and is then placed in a UDP-IP packet. With the help of MAC-in-UDP encapsulation, VXLAN tunnels Layer 2 network over Layer 3 network which provides two major benefits: higher scalability of Layer 2 segmentation and better utilization of available network pathsMP-BGP EVPN (Multiprotocol Border Gateway Protocol Ethernet Virtual Private Network) uses standard-based BGP protocol as the control plane for VXLAN overlay networks, providing BGP based VTEP auto peer discovery and end-host reachabilityinformation distribution. MP-BGP EVPN delivers many benefits, such as eliminating traffic flooding, reducing full meshrequirements between VTEPs via the introduction of BGP RR, achieving optimal flow based end to end load sharing and more Large capacities for storing ARP/ND, MAC, and ACL entriesDC-oriented features••••••DC-class HAInnovative multi-engine designFFDR provides BFD and OAM functions to implement fast failover and convergence. The following lists the DC-class HA features:Independent control, detection, and maintenance engines provide powerful control capability and millisecond-level HA:BFD for VRRP/BGP/IS-IS/RIP/OSPF/RSVP/static routing NSR/GR for OSFP/BGP/IS-IS/RSVPSeparation of control and data planes through independent control engine and switching fabric module 1+1 redundancy for control engines N+1 redundancy for switch fabric modules 1+1 redundancy for fan trays N+M redundancy for power modulesSupports a large numbers of ACLs while ensuring line-speed forwarding. ACLs can identify and control L2/IPv4/IPv6/MPLS traffic by using combinations of packet fieldsMulti-level security protectionThe S12500 switch series use QoS policies to filter and limit traffic from data plane to control plane. During a DoS attack, the switch can identify and protect important packets and discard attack packets, ensuring normal operation••Virtualization technologies - MDCMDC virtualizes one S12500 switch into multiple logicalswitches, enabling multiple services to share one core switch. The 1:N virtualization maximizes switch utilization, reduces network TCO, and ensures secure isolation of services••••Distributed buffering and precise QoSDistributed ingress buffers accommodate burst traffic. Each port performs a precise bandwidth assignment and traffic shaping for incoming traffic, and distributes the traffic to ingress buffers. Distributed buffering can fully utilize the buffers of line cards to ensure best buffering performanceA network model change from C/S to B/S leads to increased volumes of burst traffic. Network devices must have larger buffering capabilities to support this. The S12500 series supports 200ms buffering of burst traffic per 10G interface, which can meet the burst traffic requirements of large data centersEach chip can support 4GB buffer, maximum of 24GB buffer per line cardEach line card supports a maximum of 96K hardware queues, refined QoS, and traffic management. QoS can assign different priorities and queues to different users to provide differentiated services•••Comprehensive maintenance and monitoringOnline state monitoring - Uses a dedicated engine to monitor the state of switch fabric modules, backplane channels, service communication channels, key chips, and storage. Once a failure occurs, it reports the failure to the system through EMS Card isolation - Isolates specified cards from the forwarding plane. The isolated cards still work on the control plane,allowing the user to perform management operations such as real-time diagnosis and CPLD upgrade on the isolated cards without affecting system operationEthernet OAM provides multiple device-level and network-level fault detection methods••OAAOAA provides an open service platform that supports multiple service cards, including next generation firewall and netstream cards. The integration of these cards to the switch allows for unified network security solutionsGreenIntelligent EMS engine system - Provides smart power management that supports sequential power-on andpower-off and device status check. Sequential power-on and power-off reduces power impulse and electromagneticradiation, and increases the lifetime of the device. Additionally, device status checks can isolate faulty and idle cards to reduce power consumption••••Smart fan management - Collects fan temperature, calculates fan speed, and assigns the calculated speed to the fan tray. In addition, it detects fan speeds, fault alarms, and performs speed adjustment based on configurations and area, reducing power consumption and noise, increasing the fan's lifetimeInternal interface monitoring - Automatically shuts down unused internal interfaces to reduce power consumptionRoHS compliance - The S12500 switch series meets the EU RoHS safety standardsThe S12500 switch series is designed with front to back air flow, satisfying highly efficient heat dissipation requirements in data centreSpecificationsEnterprise DC applicationProvides large-capacity forwarding through its multi-level switching fabric to completely meet the traffic forwarding requirements of large data centers.Provides HA mechanisms such as BFD and FRR to ensure the availability of data center networks.Work with other H3C switches, routers and security devices to offer a complete data center solution.•••As core devices in data center networks, the S12500 series features the following:resources10GE Base-Tserver10GE server S10500S5820V2-52QF 10G server GE serverFC storageIDC ApplicationH3C Technologies Co.
