atmelan(8)
NAME
atmelan - Configures LAN-Emulation clients as network interfaces.
SYNOPSIS
/usr/sbin/atmelan command arguments
OPTIONS
This section is organized by the tasks you can perform with the atmelan
command. Each task subsection provides the atmelan command syntax and the
arguments to use to complete the tasks.
Creating a LAN-Emulation Client
Syntax:
/usr/sbin/atmelan create driver=name [type=type] [mtu=mtu] [name=elan_name]
[lecs=addr [,addr, addr, addr] | les=addr]
[unit=unit_number | elan=unit_number]
create
Creates a new LAN-Emulation Client (LEC) and configures it as a network
interface. If no additional arguments are specified, the defaults are
802.3 type and an MTU of 1516 bytes.
driver=name
Specifies the physical interface with which to associate the new LEC.
type=type
Specifies the interface type. The following types are supported:
Ethernet/802.3.
mtu=mtu
Specifies the message transfer unit (MTU) size. The following MTU sizes
are supported: 1516, 4544, 9234, and 18190. When specified with the
name option, the emulated LAN must already be configured on the ATM
switch to support the specified MTU size. If it is not configured for
the specified MTU size, the request is ignored.
name=elan_name
Specifies the name of the emulated LAN to join. The emulated LAN name
must already be configured on the ATM switch. If the name is not
configured on the ATM switch, the LEC joins the default emulated LAN.
Note
You can join an emulated LAN on a switch only once for each adapter;
do not join the same elan multiple times from the same adapter. If
you want to join the same emulated LAN on the same switch, you must
install another adapter and join the emulated LAN from it.
lecs=addr [,addr, addr, addr]
Specifies that the LEC connect to the LAN-Emulation Configuration
Server (LECS) at the ATM address specified by the addr arguments for
the emulated LAN configuration. You can specify up to 4 addresses. The
LEC tries the addresses in order until a successful configuration has
been completed. If all addresses fail, the "well known address" is
tried before the process begins again.
If no lecs option is specified (default), the LEC connects to the LECS
at the "well known address".
Do not use the lecs option with the les option.
les=addr
Specifies that the LEC go directly to the LAN-Emulation Server (LES) at
the ATM address specified by addr argument and bypass the configuration
phase.
If this argument is not specified, the LEC contacts a LAN-Emulation
Configuration Server (LECS) to obtain a LES address.
Do not use the les option with the lecs option.
unit=unit_number
Specifies a LEC interface unit number.
elan=unit_number
Specifies an ELAN unit number.
For example, to create an emulated LAN interface using Ethernet frame
format and Fiber Distributed Data Interface (FDDI) frame sizes, enter:
# atmelan create driver=lta0 mtu=4544
To create an emulated LAN interface that bypasses the configuration phase
and directly contacts a LAN-Emulation Server (LES), enter:
# atmelan create les=LES_A
The ATM address is an alias that is in the /etc/atmhosts file.
Detaching a LEC Interface from an ATM Network
Syntax:
/usr/sbin/atmelan detach
unit=unit_number | elan=unit_number
detach
Detaches a LEC interface specified by either unit or elan arguments
from an ATM network.
unit=unit_number
Specifies a LEC interface unit number. The unit_number is obtained by
the netstat -i command.
elan=unit_number
Specifies an ELAN unit number. The unit_number is obtained by the
netstat -i command.
Attaching a LEC Interface to an ATM Network
Syntax:
/usr/sbin/atmelan attach driver=name
unit=unit_number | elan=unit_number
[lecs=addr [,addr, addr, addr] | les=addr]
[name=elan_name] [type=type] [mtu=mtu]
attach
Attaches the specified, previously detached LEC network interface to an
ATM network. After the LEC interface is attached, issue the ifconfig
elanx up command to configure the interface.
driver=name
Specifies the physical interface with which to associate the LEC.
unit=unit_number
Specifies a LEC interface unit number. This is the unit number that
was previously detached.
elan=unit_number
Specifies an ELAN unit number. This is the unit number that was
previously detached.
lecs=addr [,addr, addr, addr]
Specifies that the LEC connect to the LAN-Emulation Configuration
Server (LECS) at the ATM address specified by the addr arguments for
the emulated LAN configuration. You can specify up to 4 addresses. The
LEC tries the addresses in order until a successful configuration has
been completed. If all addresses fail, the "well known address" is
tried before the process begins again.
If no lecs option is specified (default), the LEC connects to the LECS
at the "well known address".
Do not use the lecs option with the les option.
les=addr
Specifies that the LEC go directly to the LAN-Emulation Server (LES) at
the ATM address specified by addr argument and bypass the configuration
phase.
If this argument is not specified, the LEC contacts a LAN-Emulation
Configuration Server (LECS) to obtain a LES address.
Do not use the les option with the lecs option.
name=elan_name
Specifies the name of the emulated LAN to join. The emulated LAN name
must already be configured on the ATM switch. If the name is not
configured on the ATM switch, the LEC joins the default emulated LAN.
type=type
Specifies the interface type. The following types are supported:
Ethernet/802.3.
mtu=mtu
Specifies the message transfer unit (MTU) size. The following MTU sizes
are supported: 1516, 4544, 9234, and 18190. When specified with the
name option, the emulated LAN must already be configured on the ATM
switch to support the specified MTU size. If it is not configured for
the specified MTU size, the request is ignored.
Displaying State and Counters for an LEC Interface
Syntax:
/usr/sbin/atmelan show | status [unit=unit_number]
show
Shows the state and counters for a LEC interface. If no unit number is
specified, information for LEC unit 0 (elan0) is displayed.
status
Shows the state and counters for a LEC interface. If no unit number is
specified, information for LEC unit 0 (elan0) is displayed.
unit=unit_number
Specifies a LEC interface unit number, if you want to display LEC
information for LEC unit numbers other than unit 0 (elan0). The
unit_number is obtained by the netstat -i command. For example, unit 0
is elan0, unit 1 is elan1, and so on.
DESCRIPTION
The atmelan command creates and configures LAN-Emulation Clients (LEC) as
network interfaces. The first interface created appears as elan0, the
second as elan1, and so on. The atmelan command can also show counters,
parameters, and the state of each LEC.
