TABLE 5-2 /etc/opt/SUNWconn/atm/aarconfig File Flag Descriptions (Continued)

FlagDescription

tRepresents an IP to ATM address/VCI entry. aarsetup adds these entries into the local table. Any t entries on the server must contain ATM Address and may also contain VCI if PVC communication between the server and client is desired. In addition, there are some cases when a t entry may be useful on an ARP client system. If a client wants to communicate with another system over PVCs, the PVC to be used is provided in a t entry containing VCI; or if a client wants to cache frequently used addresses to avoid frequent ARP requests, a t entry containing ATM Address may be provided. See TABLE 5-3.

Note: If your naming service (NIS+ or DNS) server is an ATM host, you must provide the hostname to IP address resolution for the hosts included in t entries, either by using the IP address in the Hostname field of the t entry, or by adding an entry to the local /etc/hosts file

aRepresents an address that may have access to this host. If no a entries appear in the aarconfig file, access to the host is unrestricted. Including a entries allows access to be restricted to known hosts. As an alternative to listing individual addresses, the ATM address field may contain a prefix, followed by the wildcard $anymacsel, which matches any 7-byte ESI/Selector combination following the given prefix. This allows access by any host connected to the switch that is specified by the given prefix. Hostname and VCI should not appear; ATM Address is required. See TABLE 5-3.

mNotifies the system that the entire ATM address, including the network prefix, must be configured manually on this interface. If your interface is connected to a switch that does not support ILMI address registration, you must include this option in your /etc/opt/SUNWconn/atm/aarconfig file. Note that you may not use the variables $myaddress, $prefix, and $localswitch_server

(which use the switch prefix obtained from the switch via ILMI) if ILMI address registration is disabled.

Note –Although SunATM supports PVC connections to a server for ARP traffic, RFC 1577 does not specify this case. For interoperability with other implementations, connections to the server should use SVCs.

Note –For two hosts to communicate over PVCs, corresponding PVC connections must also be established in the ATM switch fabric.
