atmelan - Configures LAN-Emulation clients as network
interfaces.
/usr/sbin/atmelan command arguments
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 [Toc] [Back]
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]
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. Specifies the physical interface with which to
associate the new LEC. Specifies the interface type. The
following types are supported: Ethernet/802.3. 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. 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. 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.
Specifies that the LEC go directly to the LANEmulation
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.
Specifies a LEC interface 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 [Toc] [Back]
Syntax:
/usr/sbin/atmelan detach
unit=unit_number | elan=unit_number
Detaches a LEC interface specified by either unit or elan
arguments from an ATM network. Specifies a LEC interface
unit number. The unit_number is obtained by the netstat
-i command. Specifies an ELAN unit number. The unit_number
is obtained by the netstat -i command.
Attaching a LEC Interface to an ATM Network [Toc] [Back]
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]
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. Specifies the physical interface with
which to associate the LEC. Specifies a LEC interface
unit number. This is the unit number that was previously
detached. Specifies an ELAN unit number. This is the
unit number that was previously detached. 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.
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.
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. Specifies the interface type. The following
types are supported: Ethernet/802.3. 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 [Toc] [Back]
Syntax:
/usr/sbin/atmelan show | status [unit=unit_number]
Shows the state and counters for a LEC interface. If no
unit number is specified, information for LEC unit 0
(elan0) is displayed. Shows the state and counters for a
LEC interface. If no unit number is specified, information
for LEC unit 0 (elan0) is displayed. 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.
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.
