简介

本文为TCP/IP光纤信道提供一配置示例802.1Q多层导向交换机给MD。

FCIP描述了在基于IP的光纤信道(FC)存储区域网络(SAN)岛实现互连的机制,以便在单个FC光组织中组成统一的SAN。FCIP依靠基于IP的网络服务,在通过局域网、城域网或广域网的SAN岛之间提供连连通性。

由 FCIP 连接的光纤通道 SAN

FCIP在端口3225的用途传输控制协议(TCP)作为网络层传输。

先决条件

要求

IP骨干网必须是可操作和传送所需的带宽支持运行在FCIP链路间的应用程序—这可能是Layer2 (L2)或第3层(L3)拓扑。如果它是L3拓扑,必须设置和配置中间路由器或多层交换机适当地转发在FCIP通道之间的源和目的IP地址的IP数据流。如果服务质量(QoS)或流量整形被强制执行在任何网络设备在FCIP对等体之间的路径,管理IP基础设施的网络管理器应该咨询在配置任何相关参数和功能前获得必要的详细信息在多层导向交换机FCIP配置文件。是在MDSes附近的以太网交换机必须为802.1q中继支持和配置,如果子接口在MDS IP Storage (IPS)服务模块配置。

使用的组件

本文档中的信息基于以下软件和硬件版本:

  • 与IPS服务模块(DS-X9308-SMIP)运行版本1.2.(2a)的MDS9509

  • 具备 IPS 服务模块 (DS-X9308-SMIP) 1.2.(2a) 运行版本的 MDS 9509

  • 运行Catalyst OS (CatOS)的Catalyst 6509 7.4(3)

  • 带有Emulex LP9K HBA的Win2003服务器(HPQ Pro-Liant-P4)

  • IBM 存储阵列 (ESS-2105-F20)

本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始(默认)配置。如果您使用的是真实网络,请确保您已经了解所有命令的潜在影响。

背景信息

FCIP包括这些规格:

ANSI T11

  1. FC-SW-2描述FC交换机的操作和交互作用包括E_Port和结构操作。

  2. FC-BB-2是适合通过TCP网络主干的FC交换网络扩展的映射,它同时还定义了支持E_端口 和B_端口的参考模型。

IETF IPS 工作组

  1. TCP的FC包括在一个IP网络上传输FC帧的TCP/IP要求。

  2. FC 帧封装可定义普通的光纤封装格式。

IEEE 802标准

所有类型IEEE 802 LAN可能与MAC网桥一起连接,在ISO/IEC 15802-3上指定。此标准定义了的VLAN网桥操作允许VLAN结构定义、操作和管理在桥接LAN基础设施内的。

在两个SAN交换机或结构之间的互连在FCIP间呼叫FCIP链路,并且能包含一个或更多TCP连接。FCIP链路的每个结尾与虚拟E端口(VE_端口)或B_端口连接,这取决于实施情况。FC-BB 和 FC-BB-2 可描述两种方法之间的区别。IP服务模块(DS-X9308-SMIP)支持两种模式,但是默认对VE_Port,也是运行的推荐的模式,如果所有相关对等体是DS-X9308-SMIP模块。在MD平台的VE_Port功能也支持TE端口功能,由多个虚拟SAN (VSAN)使有能力中继数据流在一个FCIP实例间。驻留Cisco X9308-SMIP模块的千兆以太网(GE)接口支持802.1Q为了有效利用带宽在两个或多个FCIP通道之间的1 Gbps在低带宽需求每个FCIP通道存在的情况。一个人必须了解那共享通过使用dot1q的带宽不提供确定的带宽每个FCIP通道,当FCIP配置文件TCP参数在默认状态时被留下。

配置

在MDSes,您需要熟悉自己两平台的IPS配置指南。指南的多数当前版本可以在配置在Cisco.com的IP存储设备找到。在以太网交换机侧,一个需要熟悉dot1q中继配置特定。在本例中特定的示例, Catalyst运行混合的CatOS部署;另外配置可能适用于到其他Cisco交换机或从其他供应商的交换机。

对于Catalyst 6000系列运行混合模式,参考配置以太网VLAN中继。对于本地IOS,参考配置VLAN。对于Catalyst XL运行本地IOS的类型交换机,参考配置VLAN

本文档使用下图所示的网络设置。

拓扑 2

/image/gif/paws/47101/ips8_dot1q_2.gif

拓扑2表示在802.1Q中继间的一FCIP通道运行在IP网云的每一边。IP网云崩溃到从VLAN 1000路由流量对VLAN 500和从VLAN 500到VLAN 1000的一台多层交换机(Catalyst 6500)。VLAN 1000概念上映射对IP子网100.100.100.0/30,并且VLAN 500映射对IP子网100.100.100.4/30。MD映射并且获取dot1q帧清楚在下面配置部分的方式。为了简化,仅在一个物理接口间的一个FCIP通道在两MDSes定义;实际上,一只将使用dot1q中继共享带宽多个FCIP通道之间的一千兆接口。

关于本地VLAN不匹配的注意

在某些条件下,客户可能发现在相邻(Catalyst)以太网交换机的系统日志的本地VLAN不匹配错误消息。这指示在那些交换机trunkport的一个不正确的配置。如果子接口.1000在其中一配置在MD IP服务模块的主接口,在Catalyst交换机的相邻switchport需要建立中继为该同样VLAN ID 1000。如果,由于某种原因, Catalyst运行VLAN 1000作为端口VLAN本地VLAN,则错误消息生成,并且连接是残破的,因为从MD侧的dot1q封装的帧没有由交换机了解,并且丢弃。本地VLAN不匹配错误示例如下所示。

2003 Nov 13 02:36:39 %CDP-4-NVLANMISMATCH:Native vlan mismatch detected on port 3/7
2003 Nov 13 02:37:26 %CDP-4-NVLANMISMATCH:Native vlan mismatch detected on port 3/3
