Several rules apply to the use of variables in the aarconfig file:
■ Two variables cannot follow each other in an expression without an intervening
colon. Thus
$v1:$v2 is legal while $v1$v2 is not.
■ Fields in each line in the aarconfig file are separated by white space. Therefore,
variables should not be separated from the rest of an ATM address with white
space. For example,
$v1: $v2 is illegal.
■ Once a variable is defined by a set command, it may not be redefined later in the
same configuration file.
■ The reserved variable names cannot be set. These names include prefix , mac ,
sel , macsel , myaddress , anymac , anymacsel , sunmacsel N (where N is a
number between 0 and 199), and localswitch_server .
Note – The ESI portion of localswitch_server and the sunmacsel N variables is
a reserved MAC address. The hexadecimal values of the reserved addresses are:
localswitch_server 08:00:20:75:48:08
sunmacsel N base 08:00:20:75:48:10
To calculate the ESI portion for a sunmacsel N address, simply add the value of N
(converted to a hexadecimal number) to the sunmacsel N base address. For
example, the ESI portion of sunmacsel20 would be
08:00:20:75:48:10 + 0x14 = 08:00:20:75:48:24.
Sample Classical IP Configurations
The following examples demonstrate entries in the /etc/opt/SUNWconn/atm/
aarconfig file for several typical network configurations.
Although some of the examples show only one sample aarconfig file, similarly
configured files must appear on each system. Example 2 shows the files for each of
the three systems in the configuration.
1. SVC-only: Clients use the default address and access to the ARP server is
restricted to clients on the local switch only.
a. The /etc/opt/SUNWconn/atm/aarconfig file on a client:
