46 SunATM 3U CompactPCI Adapter Installation and User’s Guide • February 2001
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.
t
Represents 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
a
Represents 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 .
m
Notifies 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.
