Theappendixisorganizedbydatatype.Eachdatatypedescriptionincludesinformation on the nature of the data type (that is, its structure and what itrepresents), and gives examples.

Attribute value data typesAt their highest level, data types can be divided intosingle-value data typesandmultiple-value data types, as follows:

•Single-value data types represent a single value for the attribute. Thisgroup consists of the following:

—signed integer—integer sequence—decimal number—fixed point decimal—hexadecimal number—hexadecimal string—dashed hexadecimal string—IP address—enumeration2 Data types241-6401-060 Passport 6400 Components 7.0S1—string—Extended string—BCD—component name—link—time

•Multiple-value data types are types that have more than one valueassociated with the attribute. Included in this group are:

—set of...—list of...—vector of...—array of...—replicated

Component instance value data typesComponent instance value data types represent a single value for thecomponent. For details, refer to “Component name type” on page10.Included in this group are:

•signed integer•integer sequence•decimal number•hexadecimal number•hexadecimal string•dashed hexadecimal string•IP address•enumeration•stringData types 3Passport 6400 Components 7.0S1 Standard•BCD•time

Component instances have one multiple-value data type: it is the multi-indexed component.

Syntax conventionsAll command descriptions in this chapter follow these conventions:

•boldindicates a keyword explicitly typed by the operator•square brackets, [], indicate optional parameters•curled brackets, { }, indicates a choice of one of the items inside thebrackets

• indicates a user-specified parameter•an asterisk, *, indicates one or more of the previous items unlessotherwise specified

Signed integer typeThesigned integer type represents a 32-bit signed integer value. Thesupported values range from -2,147,483,648 to +2,147,483,647. On a textinterface device, a signed integer type appears as follows:

attribute_name attribute_valuewhere:attribute_value=[][]*(thatis,oneormore digits)

wheresign = one of { +, -}digit = one of { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 }

Examples0, -0, +0, 00000

65535.255(highest AppleTalk address)63.1023(highest DECnet address)

Decimal number typeThedecimalnumber type represents a 32-bit or 64-bit decimal value. On atext interface device, you can set a decimal number type as follows:

set component_name attribute_name attribute_valuewhere:attribute_value = []* (that is, one or more digits)digit = one of {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

Example> set lp/3 customerIdentifier 55

Fixed point decimal typeThefixed point decimal type represents a scaled decimal number. On a textinterface device, a fixed point decimal type is entered as follows:Data types 5Passport 6400 Components 7.0S1 Standardset component_name attribute_name attribute_valuewhere:attribute_value = [.]digits = one or more of {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}Example1.234

Hexadecimal number typeThehex number type represents a 32-bit numeric value which is input andoutput as a hexadecimal number. On a text interface device, a hex numbertype is entered as follows:

set component_name attribute_name attribute_valuewhere:attribute_value = [] * (that is, from one to four pairs of hexdigits)

hex_digit = one of {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f, A, B, C, D,E, F}
