SYNOPSIS

IFRHeader sub-command options

DESCRIPTION

The Inter-Fabric Routing Extended Header (IFR_Header) provides the necessary information to support fabric-to-fabric routing.

STANDARD OPTIONS
expirationTime

If the Expiration Time Valid (ETV) bit is set to one, the Expiration Time (Exp_Time) field is used by Inter-Fabric Routers to enforce frame lifetime requirements across the Inter-Fabric.

destinationFabricId

The Destination Fabric Identifier (DF_ID) field is set as specified in FC-IFR.

routingControl

The R_CTL field is a one-byte field that contains routing bits and information bits to categorize the frame function.

This field is set to the value 51h to identify the IFR_Header.

hopCount

The count by which the VFT header packet is forwarded in the stream.

If the Hop Count Valid (HCV) bit is set to one, the Hop Count (Hop_Cnt) field specifies the number of hops remaining before the frame is discarded.

sourceFabricId

The Source Fabric Identifier (SF_ID) field is set as specified in FC-IFR.

hopCountValid

If Hop Count field is valid, Hop Count Valid bit is set to one.

If Hop Count field is invalid, Hop Count Valid bit is set to zero.

expirationTimeValid

If EXP_Time field is valid, Expiry Time Valid bit is set to one.

If EXP_Time field is invalid, Expiry Time Valid bit is set to zero.

priority

Specifies the Quality of Service (QoS) value for the frame.

When set to zero, is interpreted to contain management information for the class of service.

version

Specifies the version of the IFR_Header.

This field is set to a default value of 00b.

COMMANDS

The IFRHeader command is invoked with the following sub-commands. If no sub-command is specified, returns a list of all sub-commands available.
