1.1. CiscoME6524系列设备介绍1.1.1. 概述Cisco6524是面向下一代网络的，集成化的包含冗余电源的高性能网络设备，基于成熟的6500系列网络设备的技术，Cisco ME6500提供高性能、高可靠性、以及QoS特性，所有这一切集成在1.5U的机架空间内，可以灵活的部署与网络的各个层面。Cisco ME6500系列设备提供对于Multiprotocol Label Switching (MPLS), quality of service (QoS), multicast, IPv6的支持，便于企业将相关的网络技术特性部署与网络的接入层。Cisco ME6500 系列设备是高性能具备丰富特性的网络交换路由设备，基于Policy Feature Card 3C (PFC3C) 以及Multilayer Switch Feature Card 2A (MSFC2A)提供丰富的二层、三层特性ME6500系列有两种可选配置： 24 千兆(SFP) 下联以及8千兆SFP 上联,配置冗余电源 Cisco ME 6524 with 24 Gigabit Ethernet SFP Downlinks 24 以太网电口10/100/1000M 下联以及8千兆SFP 上联,配置冗余电源 Cisco ME 6524 with 24 Ethernet 10/100/1000 Downlinks1.1.2. 特性Cisco ME 6524特性优势：特性说明二层交换IEEE 802.1Q802.1Q TunnelingLayer 2 Protocol Tunneling (L2PT)支持802.1Q、L2PT特性IEEE 802.1DIEEE 802.1wIEEE 802.1sFlexlinkPort Aggregation Protocol (PAgP)IEEE 802.3adUnidirectional Link DetectionProtocols such as IEEE 802.1D, IEEE 802.1w, and IEEE 802.1s help ensure business continuity by minimizing the network convergence time for time-sensitive applications.Flexlink provides fast failover over point-to-point connections, without the overhead of control protocols.PAgP and IEEE 802.3ad increase bandwidth availability and provide fast link failover within the Cisco EtherChannel bundle.Unidirectional Link Detection (UDLD) increases the network reliability by quickly detecting unidirectional links or misplaced fiber connectors.Cisco Discovery ProtocolVLAN Trunk Protocol (VTP)Cisco Discovery Protocol and VTP ease the network and service configuration by detecting peer capability and by propagating the VLANs information within the network.三层路由Open Shortest Path First (OSPF)Enhanced Interior Gateway Routing Protocol (EIGRP)Intermediate System-to-Intermediate System (IS-IS) ProtocolBorder Gateway Protocol Version 4 (BGPv4)Hot Standby Router Protocol (HSRP)Virtual Router Redundancy Protocol (VRRP)Gateway Load Balancing Protocol (GLBP)Bidirectional Forwarding Detection (BFD) for OSPF and IS-ISStatic Routing高性能三层转发能力Efficient Multicast DistributionProtocol Independent Multicast (PIM, PIM-SM, PIM-SSM)PIM SnoopingBidirectional PIMInternet Group Management Protocol version 1, 2, 3 (IGMP v1, v2, v3)IGMP SnoopingEnable efficient and scalable delivery of video applications.Advanced Quality of ServiceIngress Policing-Per Port, Per VLAN, Per Port + Per VLANPer-port egress policingDSCP TransparencyClass of service (CoS) MutationFlexible Policing functions classify and rate-limit the users traffic based on port, VLAN, and port + VLAN information. Layer 3 per-port egress policing allows the delivery of multipoint services with tight service-level agreement (SLA) requirements. User traffic can be marked at Layer 2 or Layer 3, to fulfill differentiated QoS models.Priority QueueShaped Round Robin (SRR)Deficit Weighted Round Robin (DWRR)Weighted Random Early Detection (WRED)Intelligent queuing mechanism helps ensure that the highest-priority data is serviced ahead of other traffic.Congestion avoidance and scheduling algorithms help regulate traffic and prevent network congestion. SRR enhances the scheduling algorithm by shaping the traffic that egress each queue.Robust Security SolutionPrivate VLANIEEE 802.1xDynamic Host Configuration Protocol (DHCP) SnoopingDHCP Option 82Dynamic ARP InspectionPrivate VLAN 允许用户对网络流量进行本地化和限制.IEEE 802.1x,支持端口级别的安全特性DHCP Snooping, DHCP Option 82, and Dynamic ARP Inspection 等特性可以让用户在端口层面灵活部署基于IP地址的安全特性；VLAN-based and port-based ACLsPort Security on Access, 802.1Q trunk, and 802.1Q tunneling portsPer-VLAN MAC LimitingControl Plane PolicingHardware-based Rate LimitersStorm ControlUnicast Flood BlockingMalicious attacks can jeopardize the functionality of the network by compromising the switch CPU, MAC table, etc.Features such as Port Security and Per-VLAN MAC Limiting restrict the number of MAC addresses that can be learned on the network.Hardware-enabled ACLs and rate limiters restrict undesired traffic in the network, while storm control features rate-limit the amount of broadcast and multicast frames injected into the switch.MPLSEthernet over MPLS (EoMPLS)EoMPLS VC Type 4 and VC Type 5MPLS VPN (RFC2547)MPLS Traffic Engineering (MPLS TE)MPLS Fast Reroute (MPLS FRR)支持 Layer 2 and Layer 3 MPLS services integration on the same platform.支持MPLS TE and FRR features allow to transport services with different levels of protection and service guarantees.IPv6Native IPv6RIPng, MP-BGP4, OSPFv3IPv6 over IPv4 TunnelsInternet Control Message Protocol version 6 (ICMPv6)Configured, Automatic, GRE, 6to4, ISATAP TunnelsIPv6 QoSPIM-SM and PIM-SSMImprove the scalability of IP deployments, allowing high-performing network evolution.Multicast protocols and QoS features optimize video delivery over an end-to-end IP architecture.1.1.3. 技术规格描述说明MAC 地址96,000IPv4 路由表256,000IPv6 路由表128,000EoMPLS Tunnels4096MPLS VPNs512NetFlow Entries128,000描述说明转发引擎Policy Feature Card 3C (PFC3C) onboardMSFC 特性卡MSFC2A onboard转发性能15 mpps交换容量32 Gbps上联端口8 Gigabit Ethernet SFP interfaces下联端口 24 Gigabit Ethernet SFP interfacesor 24 Ethernet 10/100/1000 interfaces（本期投标）MTU9216 bytes-Jumbo frames supported on uplink and downlink interfaces上联端口队列 TX: 1p3q8t RX: 2q8t Deep Buffer: 12.8 MB per port (50% TX and 50% RX)上联端口排队Strict Priority Scheduling with either Shaped Round Robin (SRR) or Deficit Weighted Round Robin (DWRR)下联端口队列 TX: 1p3q8t RX: 1q2t Deep Buffer TX: 21.33 MB per port Deep Buffer RX: 240 KB shared by three ports下联端口排队DWRR, Weighted Random Early Detection (WRED)USB 端口Two USB ports (host and device)描述说明内存256 MB of default DRAM for the switch processor, upgradeable to 512 MB or 1 GB.
