ATMARP(8) Maintenance Commands ATMARP(8)NAME
atmarp - administer classical IP over ATM connections
SYNOPSIS
atmarp -a
atmarp -c [[atm]number]
atmarp -q ip_addr [qos qos] [sndbuf bytes]
atmarp -s ip_addr [itf.]vpi.vci [qos qos] [sndbuf bytes] [temp] [pub] [null]
atmarp -s ip_addr atm_addr [qos qos] [sndbuf bytes] [temp] [pub] [arpsrv]
atmarp -d ip_addr [arpsrv]
atmarp -V
DESCRIPTION
atmarp is used to maintain the ATMARP table of the ATMARP demon. The table can be listed, new PVC and SVC entries can be added, and exist-
ing entries can be deleted. In addition to that, atmarp is also used to create new IP over ATM interfaces.
Note that the kernel has its own ATMARP table containing only entries for destinations to which a connection exists. The table of atmarpd
can also contain currently unused entries.
OPTIONS -a list the current ATMARP table.
-c create the specified IP interface. If the interface number is omitted, the operating system assigns the next free number and atmarp
prints the resulting interface name (e.g. `atm0') on standard output.
-q sets the QOS and the send buffer size to use as the default for all VCs generated for that IP network (ip_addr must be the address
of the network).
-s set up a PVC or create an SVC entry. The following options are recognized:
qos qos
uses the specified quality of service (see qos(7) for the syntax). UBR at link speed is used by default.
sndbuf bytes
tries to set the send buffer to the specified number of bytes. A system default value is used if sndbuf is not specified.
temp does not mark the entry as permanent, i.e. it will time out and then be removed.
pub publishes the entry (only relevant for ATMARP server). ATMARP requests for entries not marked for publishing yield an
ATMARP_NAK response.
null uses NULL encapsulation instead of LLC/SNAP encapsulation on the PVC. This option is not available for SVCs, because the
LLC/SNAP header is required to identify ATMARP packets. null also implies that the entry is permanent.
arpsrv identifies the entry pointing to the ATMARP server. Note that the node acting as the ATMARP server must have no ATMARP server
entry in its ATMARP table.
-d delete the specified ARP entry. In order to prevent accidental deletion of the ATMARP server entry, the arpsrv flag must be speci-
fied when deleting it.
-V print the version number of atmarp on standard output and exit.

atmsetup(8) System Manager's Manual atmsetup(8)NAME
atmsetup - Configures Asynchronous Transfer Mode (ATM) adapters and services
SYNOPSIS
/usr/sbin/atmsetup [-old]
OPTIONS
Invokes the atmsetup script. This option is for backward compatibility, and will be removed in a future release.
DESCRIPTION
The atmsetup command by default invokes the SysMan ATM Configuration application. This application enables you to configure and run ATM on
your system. Specifically, you can configure network adapters and logical interfaces on the adapters for the following environments: Clas-
sical IP, LAN Emulation, and IP Switching. Compaq recommends you use the SysMan application.
Note
Support for IP Switching will be retired in a future release. Do not use it to develop new applications.
During the adapter configuration, you specify the adapter name, the Endpoint System Identifiers (ESIs), pacing options, the type of network
physical layer, and whether to enable flow control, Integrated Local Management Interface (ILMI), signaling, and virtual circuit (VC)
accounting. In addition, you specify the User-Network Interface (UNI) version.
During logical interface configuration, you specify information related to each ATM environment. For Classical IP, you choose whether the
system is an ATMARP client or server and whether to configure permanent virtual circuits (PVCs). For LAN Emulation, you choose which emu-
lated LAN to join and how to join the emulated LAN. For IP Switching, you specify the Subnetwork Attachment Point (SNAP) VCI number and
VCI limits. In all three cases, you change only those default values that your configuration requires. See Asynchronous Transfer Mode for
information on configuring ATM and the ATM configuration application online help for more information.
Before invoking the atmsetup command, make sure that your system is connected to a switch, the network software is configured and running,
ATM is configured into the kernel, and the ATM subsets are installed.
After running atmsetup, you must configure the ATM interfaces with the correct IP address and netmask. Select Configure Interfaces from the
SysMan menu. See sysman(8) for more information.
atmsetup Script
If you specify the -old option, the atmsetup script is invoked. This script prompts you for all information that you need to enter in order
to configure ATM. The script creates and maintains a directory hierarchy /etc/atm, which contains all the ATM configuration information.
The atmsetup script configures the driver and signaling on an ATM end system. In addition, you can configure your system to operate in a
Classical IP or Local Area Network (LAN) emulation environment. See Asynchronous Transfer Mode for additional information on configuring
ATM on your system.
RESTRICTIONS
You must be superuser to use this command.
The atmsetup script (-old option) has the following restrictions: You can configure only lis interfaces to support SVCs and elan inter-
faces. It supports boot-time configuration only.
