1 /ATMADDRESS
/ATMADDRESS=LES sets the LAN emulation server (LES) address for
asynchronous transfer mode (ATM). Usually the address is not user
specified, and this qualifier is used only if you want a specific
address. By default the address is determined by software from
the configuration server for the LES.
The /ATMADDRESS=LES qualifier's syntax is as follows:
SET DEVICE/ATMADDRESS = ([NO]LES=the ATM server)
/ATMADDRESS=ARP sets the address resolution protocol (ARP) server
address for Classical IP over ATM. This qualifier is required
before a LIS is enabled if the local host is not the ARP server.
The /ATMADDRESS=ARP qualifier's syntax is as follows:
SET DEVICE/ATMADDRESS = (ARP=atm_arp_server)
2 /CLIP
Sets the Classical Internet Protocol (CLIP) over ATM (RFC1577).
The CLIP qualifier implements a data-link level device as a
client and/or a server in a logical IP subnet (LIS). This allows
the IP protocol to transmit Ethernet frames over the ATM network.
The /CLIP = ENABLE command causes the system to join the LIS. The
/CLIP = DISABLE command causes the client to leave the logical IP
subnet.
Note that a LIS requires a server, and there must be only one
server for each subnet. Communication between subnets can only be
performed by a router. There can only be one client for each ATM
adapter.
The /CLIP qualifier's syntax with standard Internet dotted
notation is as follows:
SET DEVICE/CLIP =(ip_subnet=a.b.c.d,
ip_address=a.b.c.d,
parent=devnam,
name="ip subnet name",
enable, disable
type = client|server)
The meanings for the syntax for /CLIP are as follows:
Option Meaning
ip_address Specifies the IP address of the CLIP
client.
ip_subnet Specifies the subnet mask of the CLIP
client.
parent=devnam Specifies the parent device name.
name Specifies a name for the LIS to aid in
operations and diagnostics.
type=client Starts up a classical IP client only. This
is the default.
type=server Starts up a classical IP server. Only one
server for each LIS is allowed, and the
server needs to be started first.
type=(server,client) Starts up a classical IP server and
client.
Keywords and their meaning for /CLIP are as follows:
Keyword Meaning
Enable Joins the logical IP subnet.
Disable Causes a client to leave the logical IP subnet.
3 /ELAN
The /ELAN qualifier has two values: enable and disable. With
/ELAN=ENABLE along with the keyword STARTUP, the LAN emulation
is loaded when LANACP starts. With /ELAN=DISABLE, the same
parameters used with ENABLE can be invoked.
The /ELAN qualifier's syntax is as follows:
DEFINE DEVICE/ELAN =(parent=parent device,
name="ELAN NAME to join",
size=1516
type=CSMACD
Enable,
Disable,
description = "description string,")
The meaning of the syntax for /ELAN is as follows:
Option Meaning
parent The ATM adapter device name. An example of the
parent device for DAPCA is: HWn0, where n is the
controller number. An example of the parent device
for DGLTA is: HCn0, where n is the controller
number.
name Optionally specified if you want to join a specific
ELAN. The default is null.
size Maximum frame size of the LAN you want to join.
Valid sizes are 1516, 4544, or 9234 bytes. The
default is 1516.
type Support currently only for CSMACD, which is the
default.
description A method of describing the ELAN for display purposes
only.
Keywords and their meanings for /ELAN are as follows:
Keyword Meaning
Enable Begins a join on a specified emulated LAN. It also loads
the driver, if not already loaded.
Disable Causes a client to leave the emulated LAN.
4 /PVC
/PVC=(vci[,...])
/[NO]PVC=(vci[,...])
Sets the permanent virtual circuit (PVC) to be used by a
Classical IP over ATM client. This is an optional qualifier.
A list of PVCs is defined for use by CLIP clients. This command
should be used before enabling the CLIP client. The PVC has to be
set up manually in the ATM switch.
The vci is the VCI (Virtual Circuit ID) of the PVC to be used.
Examples
1. LANCP> SET DEVICE/CONTENDER/MEDIA=UTP/NOEARLY/SOURCE ICA0
Enables monitor contention, UTP cable media, source routing and
disables early token release for Token Ring device ICA0.
2. LANCP> SET DEVICE/MEDIA=TWI EWB0
Sets the media type to twisted pair for the second Tulip Ethernet
device, EWB0.
3. LANCP> SET DEVICE EXA0/MOPDLL=ENABLE
Enables MOP downline load service for device EXA0, leaving the
remaining MOPDLL parameters unchanged.
4. LANCP> SET DEVICE EXA0/MOPDLL=(ENABLE,EXCLUSIVE,SIZE=1482)
Enables MOP downline load service for device EXA0, in exclusive
mode with the data transfer size of 1482 bytes, leaving the
remaining MOPDLL parameters unchanged.
5. LANCP> SET DEVICE EXA0/MOPDLL=(ENABLE,NOEXCLUSIVE)
LANCP> SET DEVICE FXA0/MOPDLL=(ENABLE,EXCL,KNOWN)
These commands enable LANACP MOP downline load service for:
o LAN device EXA0 in nonexclusive mode
o LAN device FXB0 in exclusive mode for only known clients
