Syntax for Assigning Values

Most parameters must be assigned a value of a particular type. Table 4 shows the possible types.

Table 4 Parameter Value Types

Type	Meaning	Example

Numbers	Represent the numerical value of a parameter.	15, 1024

Names	Usually represent either system-defined parameter or	Route, None
	parameter values (written as param-nameor value) or
	user-defined macros or files (written as macroname or
	filename).

Strings	Some parameter values can be set to user-defined strings,	“A,” “B,”
	ranging from a single character (written as char) to a	“password”
	multicharacter string (written as string).

Addresses	Two types of addresses can be assigned: media addresses for	#311040800245,
	Ethernet, FDDI, token ring, and wide area protocols (SMDS,	129.213.24.30
	X.25, Frame Relay) and network layer addresses.

The SET, SETDefault, and SYSgen commands require both parameter names and parameter values. The parameter name is followed by an equal sign (=) and a value. Spaces are permitted, but not required, before and after the equal sign, for example:

SETDefault -SYS ScreenLength = 30

The ADD and DELete commands also require both parameter names and parameter values. These commands modify sets of objects. No equal sign precedes the value that is added or deleted as a set member, for example:

ADD -IP ADDRess 10.0.0.1 %080002001234

Numeric Values

To assign a hexadecimal value to a parameter, precede the number with a percent sign (%). Alphabetic characters can be entered in upper- or lowercase letters.

To assign a decimal number, type the number without any preceding symbol.

Names

To assign a name, type the name in the command. Names, unlike strings, do not require quotation marks; however, the character length of the name may be limited.

Strings

String values fall into two categories: single characters and variable-length strings.

Table 5 lists the conventions for entering string values.

Table 5 Conventions for Entering Strings

String Type	Characters	Valid Characters	Examples
Single characters	Enclose in	All alphanumeric characters and	'S', 's','$'
	apostrophes.	symbols
Variable-length	Enclose in	All alphanumeric characters and	“Hello!”
strings	quotation marks.	symbols

Characters in a string are case-sensitive. For example, “ABC” is different from “abc.”

A few characters have special meaning to the bridge/router and must be preceded by a backslash (\) in string text to prevent them from being misinterpreted. These symbols are the apostrophe ('), backslash (\), caret (^), and quotation mark (“). For
