Fibre Channel Interfaces

Fiber Channel Interfaces Overview Interface Modes in MDS Family Switches

FC Interfaces Trunk ModesTrunk Mode configuration:

FC Interfaces Name and BeaconInterface WWN: Each interface is assigned a unique WWN Interface FCID:In operational Up state, each interface is assigned an FCIDIn F mode, it is the FCID assigned to the attached N-portIn FL mode, it is the Loop Fabric Address (LFA) of the portInterface Beacon:If enabled, the Port LED keeps blinkingDoes not affect operation of the interface

Interface Management InfrastructureInterface Management Services Port Manager FLOGI Manager TL Port Manager SPAN Manager Port Channel Manager VSAN Interface Manager

Basic Fibre Channel Interface Configuration

FLOGI Enhancement: FC-ID Inter-Op ModeFC-ID consists of domain-area-port. Today, most switch vendors assign one complete area to an N port attached to an F port, thus limiting the maximum number of ports in the switch to be 255.FLOGI Manager intelligently assigns single FC-ID to an N-port attached to an F port in the switch:It provides a command to disable this feature, if required.MDS-3(config)# no fcinterop fcid-allocation (No,Flat,Auto)

FLOGI Manager CLITo display the FLOGI Database:MDS-3# show flogi database ? fcidFcid: enter the fcid to be matched interfaceInterface id: enter the interface id of the port vsanVsan id:Enter the vsan number.

Advanced Interface ConfigurationsConfiguration of BB-Credit and Max Receive Buffer Size:These values may be modified for each interface.Such configuration may be needed for specific network designs to optimize bandwidth utilization or interoperate with existing fabric.Configuration of FC Timers:Values for E_D_TOV, R_A_TOV used in ELP and FLOGI may be modified on a global basis (must be the same on all switches).Any modification does not affect the active ports (in Up state) and the changes take effect only for subsequent logins (ELP or FLOGI).Important: The following configurations should be done with extreme care. For most cases the default values should work fineMake such configurations before connecting to existing fabric
