Created page with "'''LANCP''', or the LAN Control Program, is the utility that allows you to configure and control the LAN software and hardware on OpenVMS systems. It is part of OpenVMS and in..."

New page

'''LANCP''', or the LAN Control Program, is the utility that allows you to configure and control the LAN software and hardware on OpenVMS systems. It is part of OpenVMS and invoked by running SYS$SYSTEM:LANCP.EXE (via either [[RUN]] or [[MCR]]).

=Use=
LANCP can be used to:
* set LAN parameters to customize the LAN environment
* display LAN settings and counters
* provide MOP downline load support for devices such as terminal servers, x-terminals, and LAN printers, and for booting [[Satellite Node|satellites]] in an [[OpenVMS Cluster]] environment

=Supported Devices=

LAN device management consists of displaying device characteristics and setting device parameters. You can use the LANCP utility to set parameters for the types of LAN devices shown in the table below:

{| class="wikitable"
! colspan='col' | LAN
! colspan='col' | Device Examples
! colspan='col' | Description
|-
| [[Ethernet]]
| DE425, DE434, DE435, DE436, DE500, DECchip 21040
| Allow the selection of media type (type of cable connected) and the speed of connection (Ethernet or FastEthernet). Allow full-duplex operation (point-to-point operation between a similar device or between the device and a switch).
|-
| [[FDDI]]
| DEFTA, DEFPA, DEFAA, DEFEA, DEMFA,DEMNA
| Allow full-duplex operation.
|-
| [[Token Ring]] ([[Alpha]] only)
| DETRA, DW300, DW110
| Allow the setting of Token Ring parameters and the definition of source routing and functional address mapping.
|-
| All
| Any
| Allow the setting of generic parameters such as the number of receive buffers.
|-
| ATM (Alpha only)
| ATMworks 350, ATMworks 750
| The ATMworks 350 supports PCI-based systems. The ATMworks 750 supports TURBOchannel systems
|}

=Device Databases=
The LAN [[LANCP Volatile Device Database|volatile]] and [[LANCP Permanent Device Database|permanent]] device databases contain a single entry for each LAN device that exists on the system. Each entry in the LAN volatile device database contains device information and MOP downline load counters information. Each entry in the LAN permanent device database contains device information that is used to populate the volatile database when the LANACP LAN server process is started.

Typically, each database contains the same devices. However, the permanent database may contain entries for devices that have not yet been configured or installed in the system. The LANACP LAN server process maintains the volatile device database. The LANCP utility maintains the permanent device database. You can manipulate either database using the LANCP utility commands depending on your user privileges. Privileged users can add or delete device entries from each database, enable or disable MOP downline load service, and clear MOP downline load counters information for LAN devices. Unprivileged users can view the MOP downline load status and counters information.

Commands to view and modify the LAN device databases include:

|
<nowiki>
LANCP> CONNECT NODE GALAXY/DEVICE=EWA0
</nowiki>
This command attempts a console-carrier connection to node GALAXY using the Ethernet device EWA0.
<nowiki>
LANCP> CONNECT NODE 08-00-2B-11-22-33/DEVICE=EWA0/PASSWORD=0123456789AB

<nowiki>
LANCP> CONNECT NODE TERM_SERVER/DEVICE=EWA0/INPUT=LOGOUT_PORT_3.COM
</nowiki>
This command attempts a console-carrier connection to node TERM_SERVER to send the contents of the command file LOGOUT_PORT_3.COM.
|-
| CONVERT DEVICE_DATABASE
| Converts an OpenVMS Version 6.2 format device database to an OpenVMS Version 7.1 format device database.
|-
| CONVERT NODE_DATABASE
| Converts an OpenVMS Version 6.2 format node database to an OpenVMS Version 7.1 format node database.
|-
| DEFINE DEVICE
| Enters a device into the LAN permanent device database or modifies an existing entry. (To access the volatile device database, use SET DEVICE; see [[LANCP Permanent Device Database]] for qualifiers that can be used with the DEFINE DEVICE command).
|
<nowiki>
LANCP> DEFINE DEVICE EXA0/MOPDLL=(ENABLE,EXCLUSIVE)
</nowiki>
This command defines LAN device EXA0 to enable LANACP MOP downline load service in exclusive mode. The setting of the KNOWNCLIENTSONLY and SIZE characteristics are not changed. If the device entry does not currently exist in the LAN permanent device database, these settings are set to the defaults.
<nowiki>
LANCP> DEFINE DEVICE/ALL/MOPDLL=NOEXCLUSIVE
<nowiki>
This command sets all LAN devices defined in the LAN permanent device database to nonexclusive mode for LANACP MOP downline load service.
<nowiki>
LANCP> DEFINE DEVICE/ALL/UPDATE/VOLATILE_DATABASE
</nowiki>
This command enters all Ethernet devices into the LAN permanent device database and updates the entry to include the current parameter values.
|-
| DEFINE NODE
| Enters a node into the LAN permanent node database or modifies an existing entry.
|
<nowiki>
LANCP> DEFINE NODE GALAXY/ADDRESS=08-00-2B-11-22-33 -
/FILE=NISCS_LOAD.EXE -
/ROOT=$64$DIA14:<SYS10.> -
/BOOT_TYPE=VAX_SATELLITE
</nowiki>
This command sets up node GALAXY in the LAN permanent node database for booting as a VAX satellite into an OpenVMS Cluster.
The NISCS_LOAD.EXE file is actually located on $64$DIA14:<SYS10.SYSCOMMON.SYSLIB>. The <SYSCOMMON.SYSLIB> is supplied by the LANACP LAN Server process and is not included in the root definition.
<nowiki>
LANCP> DEFINE NODE ZAPNOT/ADDRESS=08-00-2B-11-22-33 -
/FILE=APB.EXE -
/ROOT=$64$DIA14:<SYS10.> -

</nowiki>
This command sets up node ZAPNOT for booting as an Alpha satellite into an OpenVMS Cluster.
The APB.EXE file is actually located on $64$DIA14:<SYS10.SYSCOMMON.SYSEXE>. Note that the <SYSCOMMON.SYSEXE> is supplied by the LANACP LAN Server process and is not included in the root definition.
<nowiki>
LANCP> DEFINE NODE CALPAL/ADDRESS=08-00-2B-11-22-33 -
/FILE=APB_061.EXE
</nowiki>
This command sets up node CALPAL for booting an InfoServer image. It defines the file that should be loaded when a load request without a file name is received from node CALPAL. Because the file does not include a directory specification, the logical name LAN$DLL defines where to locate the file. You could give directory specification using the file name or by using the /ROOT qualifier. Note that specifying the file name explicitly in the boot command overrides the file name specified in the node database entry.
