Editing the atmconfig File
The /etc/opt/SUNWconn/atm/atmconfig file is a generic file that must appear
on every SunATM system. The file provides general configuration information used
by the SunATM setup utilities to bring up SunATM interfaces that are plumbed
(using the
atmifconfig utility).
The file consists of one or more entries per interface. An entry contains the fields
described in
TABLE 5-1 .
The Interface and UNI fields are required for all interfaces. The CIP_Host field is
required for interfaces that run Classical IP, and the LANE_Instance and LANE_Host
fields are required for interfaces that run LAN Emulation. If a field is not used, it is
represented by a hyphen.
Caution – Modifications to individual interfaces will take effect when the interface
is plumbed. This will happen at boot time or when you use the atmifconfig utility
to plumb interfaces. If you plan to modify an existing (already running) interface,
you must first unplumb it with the
atmifconfig utility. Refer to the
atmifconfig(1m) man page or Chapter 6 for more information.
TABLE 5-1 /etc/opt/SUNWconn/atm/atmconfig Field Descriptions
Field Description
Interface Physical interface, ba N.
UNI/Framing Version of the UNI specification used for signalling,
3.0, 3.1, or 4.0; or, for entries with only two fields, the Framing
Interface, SONET or SDH.
CIP_Host Hostname used for Classical IP.
LANE_Instance Instance number for a LAN Emulation interface; LAN Emulation
interfaces will be called
lane N where N is the LAN Emulation
instance number. The LANE instance number must be between 0
and 999.
Note: The LANE instance number is not necessarily the same as the
physical instance number.
LANE_Host Hostname used for LAN Emulation
