STANDARD OPTIONS
destinationFormat

The format of the name identifier used for the network destination address.

ieee48BitAddressDest

When the Name_Identifier format is IEEE 48-bit Address, the name value contains a 48-bit IEEE Standard 802.1A Universal LAN MAC Address (ULA). The ULA is represented as an ordered string of six bytes numbered from 0 to 5. ULA Bytes 0, 1, and 2 are generated using the IEEE Company_ID.

The name identifier for IEEE 48 Bit Destination Address format is as follows:

Option

Usage

48BitAddressName

Identifier

The 48 bit address name identifier when the destination address format is IEEE 48 Bit Address.

ieeeExtendedDest

When the Name_Identifier format is IEEE Extended, the name value contains the 48-bit IEEE address preceded by a 12 bit value. The 12 bit value is an extension to the company assigned address portion of the 48-bit address that forms a unique 60-bit value. The 48-bit IEEE address is defined same as for the IEEE 48-bit Address Name_Identifier format.

The name identifier for IEEE Extended Destination Address format is as follows:

Option

Usage

48BitAddressName

Identifier

The 48 bit address name identifier when the destination address format is IEEE 48 Bit Address.

vendorSpecific

The vendor specific identifier that is mapped with the address format. It is true only when destination address format is IEEE Extended.

locallyAssignedDest

When the Name_Identifier format is locally assigned, the name value field is assigned in a manner determined by the administration of the Fabric in which it is assigned. A locally assigned Name_Identifier is unique within the Fibre Channel interaction space wherein it is assigned.

The name identifier for Locally Assigned Destination Address format is as follows:

Option

Usage

locallyAdministered

Value

The locally administered value that is present only when destination address format is Locally Assigned.

ieeeRegisteredDest

When the Name_Identifier format is IEEE Registered, the name value field contains the 24-bit IEEE Company_ID in canonical form, as specified by IEEE, followed by a 36-bit unique Vendor Specified Identifier (VSID).

The name identifier for IEEE Registered Destination Address format is as follows:

Option

Usage

ieeeCompanyId

The IEEE Company Identifier.

vendorSpecificId

The vendor specific identifier that is mapped with the address format.

ieeeRegistered

ExtendedDest

When the Name_Identifier format is IEEE Registered Extended, the name value contains the 24-bit IEEE Company_ID in canonical form, as specified by IEEE, followed by a 36-bit unique vendor specified id (VSID). Name_Identifiers that identify Fibre Channel Nodes or FC_Ports are limited to 64 bits and therefore will not use the IEEE Registered Extended format.

The name identifier for IEEE Registered Extended Destination Address format is as follows:

Option

Usage

ieeeCompanyId

The IEEE Company Identifier.

vendorSpecificId

The vendor specific identifier that is mapped with the address format.

vendorSpecificId

Extension

The vendor specific identifier extension that is present only when destination address format is IEEE Registered Extended.

eui64MappedDest

When the Name_Identifier format is EUI64 Mapped, The NAA field contains either 0Ch, 0Dh, 0Eh, or 0Fh. The name value field contains a modified 22-bit IEEE Company_ID, followed by a 40-bit unique VSID.

The name identifier for EUI64 Mapped Destination Address format is as follows:

Option

Usage

ieeeCompanyId

The IEEE Company Identifier.

vendorSpecificId

The vendor specific identifier that is mapped with the address format.

sourceFormat

The format of the name identifier used for the network source address.

ieee48BitAddressSrc

When the Name_Identifier format is IEEE 48-bit Address, the name value contains a 48-bit IEEE Standard 802.1A Universal LAN MAC Address (ULA). The ULA is represented as an ordered string of six bytes numbered from 0 to 5. ULA Bytes 0, 1, and 2 are generated using the IEEE Company_ID.

The name identifier for IEEE 48 Bit Source Address format is as follows:

Option

Usage

48BitAddressName

Identifier

The 48 bit address name identifier when the source address format is IEEE 48 Bit Address.

ieeeExtendedSrc

When the Name_Identifier format is IEEE Extended, the name value contains the 48-bit IEEE address preceded by a 12 bit value. The 12 bit value is an extension to the company assigned address portion of the 48-bit address that forms a unique 60-bit value. The 48-bit IEEE address is defined same as for the IEEE 48-bit Address Name_Identifier format.

The name identifier for IEEE Extended Source Address format is as follows:

Option

Usage

48BitAddressName

Identifier

The 48 bit address name identifier when the source address format is IEEE 48 Bit Address.

vendorSpecific

The vendor specific identifier that is mapped with the address format. It is true only when source address format is IEEE Extended.

locallyAssignedSrc

When the Name_Identifier format is locally assigned, the name value field is assigned in a manner determined by the administration of the Fabric in which it is assigned. A locally assigned Name_Identifier is unique within the Fibre Channel interaction space wherein it is assigned.

The name identifier for Locally Assigned Source Address format is as follows:

Option

Usage

locallyAdministered

Value

The locally administered value that is present only when source address format is Locally Assigned.

ieeeRegisteredSrc

When the Name_Identifier format is IEEE Registered, the name value field contains the 24-bit IEEE Company_ID in canonical form, as specified by IEEE, followed by a 36-bit unique Vendor Specified Identifier (VSID).

The name identifier for IEEE Registered Source Address format is as follows:

Option

Usage

ieeeCompanyId

The IEEE Company Identifier.

vendorSpecificId

ieeeRegistered

ExtendedSrc

When the Name_Identifier format is IEEE Registered Extended, the name value contains the 24-bit IEEE Company_ID in canonical form, as specified by IEEE, followed by a 36-bit unique vendor specified id (VSID). Name_Identifiers that identify Fibre Channel Nodes or FC_Ports are limited to 64 bits and therefore will not use the IEEE Registered Extended format.

The name identifier for IEEE Registered Extended Source Address format is as follows:

Option

Usage

ieeeCompanyId

The IEEE Company Identifier.

vendorSpecificId

The vendor specific identifier that is mapped with the address format.

vendorSpecificId

Extension

The vendor specific identifier extension that is present only when source address format is IEEE Registered Extended.

eui64MappedSrc

When the Name_Identifier format is EUI64 Mapped, The NAA field contains either 0Ch, 0Dh, 0Eh, or 0Fh. The name value field contains a modified 22-bit IEEE Company_ID, followed by a 40-bit unique VSID.

The name identifier for EUI64 Mapped Source Address format is as follows:

Option
