Chapter 5 Editing SunATM Configuration Files 47
TABLE 5-3 describes the required, optional, and illegal fields for each flag type. If a
field is unused, it is represented by a hyphen.
Note – Group entries in the aarconfig file in a designated order: the local (l or L)
entry first, followed by any other flags in any order. You only need to maintain the
ordering within entries for each physical interface; for example, all of the ba0 entries
can appear first, and then all of the ba1 entries, etc.
Using Variables in the aarconfig File
Because the prefix portion of an ATM address specifies the ATM switch, a number of
hosts specified in an aarconfig file can have ATM addresses that share the same
prefix. To simplify setting up the aarconfig file, you can define variables that
contain part of an ATM address.
A variable’s name is an identifier consisting of a collection of no more than 32 letters,
digits, and underscores. The value associated with the variable is denoted by a
dollar sign followed immediately by the variable name.
Note – Use variables in the ATM address field only. They are not valid in any of the
other fields in an entry.
You can use a colon to concatenate multiple variables to represent a single ATM
address expression. Thus, if one variable, v1, is set to 11:22 and another variable,
v2, is set to 33:44, the sequence $v1:$v2 represents 11:22:33:44. You can
include hexadecimal numbers with variables in the expression. The expression
45:$v1:$v2 would have the value 45:11:22:33:44.
