Chapter 5 Editing SunATM Configuration Files 45
Every node, or client, has both an IP address and either an ATMaddress or a virtual
circuit identifier (VCI). See “ATMAddress Resolution” on page 67, for ATM
addressing scheme information.
In the IP-ATMaddress table shown in the /etc/opt/SUNWconn/atm/aarconfig
file:
■Interface is the last part of the device name (ba0, for example).
■Hostname is either an IP address in “dot” notation or the name of a host that
should be locally available unless a non-ATMnetwork connection also exists.
■ATM Address consists of 20 octets with each octet represented by a one- or two-
digit hexadecimal number and separated by colons.
■The VCI field is a positive decimal integer.
■An unused field is denoted by a hyphen.
TABLE5-2 lists the flags, including configuration flags, and the options they provide.
TABLE5-2 /etc/opt/SUNWconn/atm/aarconfig File Flag Descriptions
Flag Description
lRepresentsthe ATM address of the local interface on ARP clients or systems not
using an ARP server for ATMaddress resolution, and can be used to assign an
ATMaddress to the host. Hostname should not appear; ATM Address should be
providedif, and only if, SVCs are used. If you provide an sentry to use an ARP
server (see below), you must also providean ATM Address (a server is
meaningful only in an SVC environment).See TABLE 5-3.
LRepresentsthe ATM address of the local interface on an ARP server. Hostname
should not appear; ATMAddress is required. See TABLE 5-3.
sSpecifiesa connection to the ATM ARP server. Either ATM Address or VCI (in
thecase of a PVC connection) should appear, but not both. Hostname should not
appear.The sentry is required on all clients that need to communicate with the
server for ATMaddress resolution. See TABLE 5-3.
