NAME

aarsetup − ATM Address Resolution Table setup program

SYNOPSIS

/opt/SUNWatm/bin/aarsetup [ −bnkpv ] [ filename ]

AVAILABILITY

SUNWatmu

DESCRIPTION

The aarsetup program reads a local ATM to IP address resolution table from the /etc/aarconfig file and loads the information into the kernel.  In addition, aarsetup will determine whether it is executing on the client or the server and will configure the Classical IP kernel modules appropriately. 

If an ATM ARP server exists on a subnet, the configuration file on clients need only contain the system’s local information and the server information.  If an ATM ARP server is not being used, each system’s configuration file must contain IP/ATM address resolution information for every host which it needs to contact. See the aarconfig(4) man page for details on the format of the configuration file. 

By default, the /etc/aarconfig file is read and downloaded into the local kernel table on startup.  If the configuration file is modified later, aarsetup must be rerun to load the new information into the kernel. 

OPTIONS

-b Do not attempt to load local table (’t’) entries.  This option is used during boot before the naming service is running, when IP hostnames included in the ’t’ entries cannot be resolved. 

-n Only parse the configuration table.  Using this option, the syntax and information in the table can be checked to verify that it is acceptable to the aarsetup program without actually attempting to download any data.  Physical interface information entered in the table is compared with known configured interfaces; IP addresses must be on the correct subnet for the corresponding physical interface in an entry.  In order to do this checking, the physical interface must be configured.  The -k option will omit the network checks.  Error messages will be printed if any problems are encountered. 

-k Only parse the configuration table, but do not check configured interfaces.  Using this option, only the syntax of the configuration is checked; no verification of IP address information is performed.  This enables a check of the configuration file before the physical interfaces have been configured. 

-p Prints to the standard output the table entries from the configuration file, with all variable expressions expanded. Does not download any information into the kernel. 

-v Verbose mode.  Additional information is printed. 

filename A filename may be specified to download a configuration file other than /etc/aarconfig.  Standard input, indicated with a hyphen ‘-’, is a legal value for filename if the -n option is being used. 

FILES

/etc/aarconfig ATM to IP address registration configuration file.  Contains entries which specify ATM and IP address pairs for systems.

NOTES

In this context, "server" and "client" refer to an ATM ARP server and nodes on the subnet which it serves, respectively.
