Sun Microsystems 3U Editing the atmconfig File, Etc/opt/SUNWconn/atm/atmconfig Field Descriptions

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.

TABLE 5-1 /etc/opt/SUNWconn/atm/atmconfig Field Descriptions

Field	Description
Interface	Physical interface, baN.
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 laneN 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

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.
