Example Configuration Overview




9/67

FCIP/FCR

Once the switch (SW7500) is configured, the switchShowcommand displays 32 Fibre Channel ports (port numbers 0 through

31) and 2 GbE ports.

The first 16 Fibre Channel ports are physical ports on the SilkWorm



, -

physical GbE link and ports 24-31 are virtual ports associated withGE1 physical GbE link. The GbE ports are displayed as ge0 andge1 and are not assigned port numbers or area numbers.


10/67

FCIP/FCR

NOTE: Fabrics connected through FCIP merge if the ports areconfigured as VE_Ports, and do not merge if they are configured as

VEX_Ports.

If VE_Ports are used in a Fibre Channel Routing Servicesbackbone fabric configuration, then the backbone fabric merges butthe EX Port attached to ed e fabrics do not mer e.



_


11/67

FCIP/FCR

NOTE: The port types for FCIP tunneling are either VE_Port orVEX_Port. An FCIP tunnel using VE_Ports will merge the two

fabrics.

An FCIP tunnel using a VEX_Port will not merge the fabrics.

A VEX_Port can connect only to a VE_Port.



The IP encapsulation of the Fibre Channel frame on one port andthe reconstruction of Fibre Channel frames on the other port istransparent to the initiator and target.


12/67

FCIP/FCR

NOTE: If using FCIP in your FC-FC Routing configuration, youmust first configure FCIP tunnels.

Once a tunnel is created, it defaults to a disabled state. Thenconfigure the VE_Port or VEX_Port. After the appropriateports are configured, enable the tunnel.




13/67

BROCADE FCR/FCIP

Secure Fabric OS, Management Server Platform services, andinteropmode are notsupported in the backbone fabric.

FOS 5.2 and above support FC-FC connections to McDATA Fabrics.Fabric OS v5.2.0 furnishes the FC router with the ability to connect toMcDATA fabrics in both McDATA Open or McDATA Fabric mode.




14/67

BROCADE FCR/FCIP

Ensure fabric OS is at v5.1 or later.

Fabric OS 5.2 or later is required if connecting to McDATA Fabrics

Configure FCIP Tunnels

After you have verified licensing and connectivity between your sourceand destination IP interfaces, you can configure FCIP tunnels. As youyour tunnel configurations, be aware that uncommitted rate tunnels use

a minimum of 1000 Kbps, up to a maximum of available uncommittedbandwidth on the GbE port.

The total bandwidth available on a GbE port is 1 Gbps. You can

55/67

g

s




56/67

g

Create a zone with the same members (e.g., HBA in fabric A, storageport in fabric B) coded with the PWWN of the device.

The zone mustuse the naming convention LSAN_ZONENAME orlsan_zonename Note that the name of the zone to the right of theunderscore character can be anything you want, as long as the aboveconvention is used.


It is administratively easier if the zone name is the same in each edgefabric, though this is not required as long as the members of the zoneare identical.



57/67

g

An LSAN consists of zones in two or more edge or backbone fabricsthat contain the same device(s).

LSANs essentially provide selective device connectivity between fabricswithout forcing you to merge those fabrics. The SilkWorm 7500, 48000with a FR4-18i blade, and AP7420 Multiprotocol Router provide

multi le mechanisms for ou to mana e interfabric device connectivit


through extensions to existing switch management interfaces. You can

define and manage LSANs using Brocade Advanced Zoning or BrocadeFabric Manager.

Zones are locally defined. Names and memberships, with the exceptionof hosts and targets exported from one fabric to another, do not need to

be coordinated with other fabrics.



58/67

g

Zones that contain hosts and targets that are shared between the twofabrics need to be explicitly coordinated. Although an LSAN is managedusing the same tools as any other zone on the edge fabric, two

behaviors distinguish an LSAN from a conventional zone:

A required naming convention. The name of an LSAN begins with theprefix LSAN_. The LSAN name is letter case insensitive; for example,


san_ s equ va en o _, san_, an so on.

Members must be identified by their port WWN because PIDs are notnecessarily unique across fabrics. The names of the zones need not beexplicitly the same, and membership lists of the zones need not be inthe same order.



59/67

NOTE:

If you are managing other switches in a fabric, it is recommended that

you run the defZone show command on your Fabric OS v5.1.0switches as a precaution. Default zoning behavior in Fabric OS v5.1.0

operates differently compared to other Fabric OS versions (for example,


vers ons .x, .x .x an . . . or examp e, you ssue e e one --

noaccess command on a Fabric OS v5.1.0 switch, then default zoningconfigurations will be created on each switch in the fabric (v2.x, v3.x,v4.x or v5.0.1 switches). Fabric OS v5.1.0 switches do not indicate thata default configuration is enabled when you use the cfgShow orcfgActvShow commands.

WAN Analysis

Introduced in Fabric OS v5.2.0, WAN analysis tools are designed toestimate the end-to-end IP path performance characteristics between apair of Brocade FCIP port endpoints. WAN tools include the following

commands and options:

portCmd ipPerfCharacterizes end-to-end IP path performancebetween a pair of Brocade FCIP ports.



You can use the WAN tool ipPerfonly on the FR4-18i or SilkWorm 7500FCIP ports running Fabric OS v5.2.0 or later software.
