LANCP> DEFINE DEVICE/ALL/UPDATE/VOLATILE_DATABASE |
This command enters all Ethernet devices into the LAN permanent device database and updates the entry to include the current parameter values.
Enters a node into the LAN permanent node database or modifies an existing entry. Requires SYSPRV privilege.
DEFINE NODE node-name
node-name
Supplies the name of a node to be added to the LAN permanent node database or an entry to be modified. Typically, the node name is the same as that given in the system parameter SCSNODE, but it does not need to be. The node name is limited to 63 characters in length.
/ADDRESS=node-address
/NOADDRESS (default)
Associates a LAN address with the node name. Specify the address as 6 bytes in hexadecimal notation, separated by hyphens. The address does not have to be unique (as might be the case when the address is not known, so a nonexistent address is specified).If multiple node addresses are to be associated with a node name, each combination may be given as a node name with an extension, for example, VAXSYS.EXA for the EXA device on node VAXSYS, or VAXSYS_1 for the first LAN device on node VAXSYS.
If you do not specify the /ADDRESS qualifier, the setting remains unchanged. The /NOADDRESS qualifier clears the field.
/ALL
Defines data for all nodes in the LAN permanent node database. If you specify a node name, all matching nodes are selected; for example, A/ALL selects all nodes beginning with A./BOOT_TYPE=boot-option
/NOBOOT_TYPE
Indicates the type of processing required for downline load requests. You can specify one of the following keywords with this qualifier:The distinction is necessary, because OpenVMS Cluster satellite loads require additional cluster-related data be appended to the load image given by the /FILE qualifier. The default value is OTHER.
- VAX_SATELLITE---an OpenVMS Cluster VAX satellite boot
- ALPHA_SATELLITE---an OpenVMS Cluster Alpha satellite boot
- OTHER---the specified image; a noncluster satellite load that does not require additional data
If you do not specify the /BOOT_TYPE qualifier, the setting remains unchanged. The /NOBOOT_TYPE qualifier clears the field.
/DECNET_ADDRESS=value
/NODECNET_ADDRESS
Associates a DECnet address with the node name. Specify the address in DECnet notation, xx.xxxx.If you do not specify the /DECNET_ADDRESS=value qualifier, then the setting remains unchanged. The /NODECNET_ADDRESS qualifier clears the field.
/FILE=file-spec
/NOFILE
Supplies the file name of a boot file to be used when the downline load request does not include a file name (for example, with OpenVMS Cluster satellite booting). The file specification is limited to 127 characters.If no file name is specified, OpenVMS Cluster satellite loads default to APB.EXE where the boot type is set to ALPHA and NISCS_LOAD.EXE where the boot type is set to VAX.
If you do not specify the /FILE qualifier, the setting remains unchanged. The /NOFILE qualifier clears the field.
/IP_ADDRESS=value
/NOIP_ADDRESS
Associates an IP address with the node name. Specify the address in the standard dotted notation, xxx.xxx.xxx.xxx.If you do not specify the /IP_ADDRESS=value qualifier, the setting remains unchanged. The /NOIP_ADDRESS qualifier clears the filed.
/ROOT=directory-specification
/NOROOT
Supplies the directory specification to be associated with the file name. For cluster satellite service, the /ROOT qualifier specifies the satellite root directory. For noncluster service, this qualifier specifies the location of the file. If the file specification or the file name given in the boot request includes the directory name, this qualifier is ignored. The directory specification is limited to 127 characters.If you do not specify the /ROOT qualifier, the setting remains unchanged. The /NOROOT qualifier clears the field.
/SIZE=value
/NOSIZE
Specifies the size in bytes of the file data portion of each downline load message. The default is the load data size specified for the device. The permitted range is 246 to 1482 bytes. Use a larger size for better load performance and less server overhead.If you do not specify the /SIZE qualifier, the setting remains unchanged. The /NOSIZE qualifier clears the setting.
/V3
/NOV3
Indicates that only MOP Version 3 formatted messages are to be used for downline load purposes, regardless of the requested format. This allows systems that have a problem with MOP Version 4 booting to load. This qualifier causes the requesting node to fail over from MOP Version 4 to MOP Version 3 when no response has been made to a MOP Version 4 load request.If you do not specify the /V3 qualifier, the setting remains unchanged. The /NOV3 qualifier clears the setting.
/VOLATILE_DATABASE
Updates the node entries in the LAN permanent node database with any data currently set in the volatile database. This allows you to update the permanent database after changing data in the volatile database, rather than repeating the commands for each updated entry to apply the changes to the permanent database.

LANCP> DEFINE NODE GALAXY/ADDRESS=08-00-2B-11-22-33 - /FILE=NISCS_LOAD.EXE - /ROOT=$64$DIA14:<SYS10.> - /BOOT_TYPE=VAX_SATELLITE |
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.

LANCP> DEFINE NODE ZAPNOT/ADDRESS=08-00-2B-11-22-33 - /FILE=APB.EXE - /ROOT=$64$DIA14:<SYS10.> - /BOOT_TYPE=ALPHA_SATELLITE |
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.

LANCP> DEFINE NODE CALPAL/ADDRESS=08-00-2B-11-22-33 - /FILE=APB_061.EXE |
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.
Stops execution of LANCP and returns control to the DCL command level. You can also enter Ctrl/Z at any time to exit.
EXIT
None.
None.
LANCP> EXIT $ |
This command stops execution of LANCP and returns control to the DCL command level.
Provides online help information about the LANCP utility.
HELP [topic]

This command provides online help for the LANCP command DEFINE DEVICE.
Displays information in the LAN permanent device database.
LIST DEVICE device-name
device-name
Supplies the LAN controller device name. The device name has the form ddcu where dd is the device code, c is the controller designation, and u is the unit number. LAN devices are specified as the name of the template device which is unit 0. For example, the first DE435 Ethernet device is specified as EWA0, the second as EWB0.For example, you can specify a DEMNA controller as EXA, EXA0, or EXA0:. This refers to the LAN template device, for which is maintained most of the device parameters and counters. Also, the device name can refer to a device unit representing an actual user or protocol. For example, the cluster protocol can be started on a device as EWA1. You can specify a device unit to view unit-specific parameter information.
If you do not specify a device name, all devices are displayed.
If you specify a device name, all matching LAN devices are displayed, for example: E to select all Ethernet devices, F for FDDI, I for Token Ring, EW to select all Ethernet PCI Tulip devices.
If you do not specify a qualifier, the utility displays the matching devices without additional information. |

LIST NODE node-name
node-name
Specifies the node name. The name can include up to 63 characters associated with the node address. If no node name is given, all nodes are displayed.
/ALL
Displays data for all nodes in the LAN permanent node database. If you specify a node name, all matching nodes are selected; for example, A/ALL selects all nodes beginning with A./OUTPUT=file-name
Creates the specified file and directs output to that file. If the file extension is .com, the output is in the form of a list of DEFINE NODE or SET NODE commands. The resulting command file can be used to create the LAN node databases.
LANCP> LIST NODE Node Listing: GALAXY (08-00-2B-2C-51-28): MOP DLL: Load file: APB.EXE Load root: $64$DIA24:<SYS11.> Boot type: Alpha satellite ZAPNOT (08-00-2B-18-7E-33): MOP DLL: Load file: NISCS_LOAD.EXE Load root: LAVC$SYSDEVICE:<SYS10.> Boot type: VAX satellite CALPAL (08-00-2B-08-9F-4C): MOP DLL: Load file: READ_ADDR.SYS Last file: LAN$DLL:APB_X5WN.SYS Boot type: Other 2 loads requested, 1 volunteered 1 succeeded, 0 failed Last request was for a system image, in MOP V4 format Last load initiated 10-JUN-1998 09:11:17 on EXA0 for 00:00:06.65 527665 bytes, 4161 packets, 0 transmit failures Unnamed (00-00-00-00-00-00): Totals: Requests received 2 Requests volunteered 1 Successful loads 1 Failed loads 0 Packets sent 2080 Packets received 2081 Bytes sent 523481 Bytes received 4184 Last load CALPAL at 10-JUN-1998 09:11:17.29 |
This example shows output from a LIST NODE command issued on a local node on which there are three nodes defined (GALAXY, ZAPNOT, and CALPAL). CALPAL has issued two load requests:
- The first request is the multicast request from CALPAL that the local node volunteered to accept.
- The second request is the load request sent directly to the local node by CALPAL for the actual load data. The elapsed time from the second load request to completion of the load was 6.65 seconds.
Deletes a device from the LAN permanent device database. Requires SYSPRV privilege.
PURGE DEVICE device-name
device-name
Supplies the LAN controller device name. The device name has the form ddcu where dd is the device code, c is the controller designation, and u is the unit number. LAN devices are specified as the name of the template device which is unit 0. For example, the first DE435 Ethernet device is specified as EWA0, the second as EWB0.For example, you can specify a DEMNA controller as EXA, EXA0, or EXA0:. To select all LAN devices, omit the device name and include the /ALL qualifier.

Modifies the operation of the LANACP LAN Server process. Requires SYSPRV privilege.
SET ACP
None.
/ECHO
/NOECHO (default)
Enables partial tracing of received and transmitted downline load messages (the first 32 bytes of the data portion of each message). Note that the last one or two MOP messages are displayed in full: the memory load message with cluster parameters, and the parameter load with transfer address message, where present in the load.The data is written to a log file SYS$MANAGER:LAN$node-name.LOG.
To obtain the entire contents of each message, use the /FULL qualifier as follows:
SET ACP/ECHO/FULL
/FULL
/NOFULL (default)
When /ECHO is enabled, displays the entire contents of received and transmitted downline load messages./OPCOM (default)
/NOOPCOM
Enables OPCOM messages from LANACP LAN Server process.Messages are generated by the LANACP LAN Server process when a device status changes, load requests are received, and loads complete. These messages are displayed on the operator's console and included in the log file written by LANACP, SYS$MANAGER:LAN$ACP.LOG.
/STOP
Stops the LANACP process. It can be restarted by reexecuting the SYS$STARTUP:LAN$STARTUP command file.
LANCP> SET ACP/ECHO/FULL |
This command enables tracing of received and transmitted downline load messages. The /FULL qualifier displays the entire contents of received and transmitted downline load messages.
On Alpha systems, sets or modifies LAN device parameters. Requires PHY_IO privilege.
SET DEVICE device-name
device-name
Specifies a device to be entered in the LAN volatile device database, or whose parameters are to be modified. The device name has the form ddcu where dd is the device code, c is the controller designation, and u is the unit number. LAN devices are specified as the name of the template device which is unit 0. For example, the first DE435 Ethernet device is specified as EWA0, the second as EWB0.
/AGING_TIMER=value
Sets the amount of time in seconds to age Token Ring source routing cache entries before marking them stale. This timer expires when no traffic is sent to or received from the remote node in this amount of time. The default value is 60 seconds.Increase this value when idle connections bounce between the stale and known states. Setting this value too low may cause unnecessary explorer traffic to traverse the LAN.
/ALL
Sets data for all LAN devices. If you specify a device name, all matching LAN devices are selected, for example: E to select all Ethernet devices, F for FDDI, I for Token Ring, EW to select all Ethernet PCI Tulip devices./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 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)/CACHE_ENTRIES=value
Sets the number of entries to reserve for caching Token Ring source routing address entries. The default value is 200 entries.If your system directly communicates to a large number of systems, you may want to increase this number.
/CLIP
On Alpha systems, the Classical Internet Protocol (CLIP) qualifier sets a device with the TCP/IP protocol that enables it to see a network as being configured as one or more logical IP subnets (LIS), which allows the Alpha system to transmit Ethernet frames over the ATM network. The /CLIP = ENABLE command causes the system to join the LIS when LANCP initializes. 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. Also, there can only be one client for each ATM adapter.
The /CLIP qualifier's syntax with standard Internet dotted notation is as follows:
DEFINE 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 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.
/CONTENDER
/NOCONTENDER (default)
Specifies that the Token Ring device is to participate in the Monitor Contention process when it joins the ring. The /NOCONTENDER qualifier, directs the device not to challenge the current ring server./DISCOVERY_TIMER=value
Sets the number of seconds to wait for a reply from a remote node when performing the source Token Ring routing route discovery process. The default value is 2 seconds.If you have nodes that respond slowly on your extended LAN, you may need to increase this number to reduce the amount of explorer traffic that traverses your LAN.
/DLL=(enable-option, exclusive-option, size-option, knownclientsonly-option)
Provides the MOP downline load service settings for the device.Note that defaults apply to creation of an entry in the device database. If an existing entry is being modified, fields not specified remain unchanged.
You can specify the following keywords with this qualifier:
- enable-option
ENABLE
DISABLE (default)
Specify ENABLE or DISABLE to indicate that MOP downline load service should be enabled or disabled for the device.- exclusive-option
EXCLUSIVE
NOEXCLUSIVE (default)
Specify EXCLUSIVE to indicate that no other provider of MOP downline load service is allowed on the specified LAN device at the same time as LANACP. Specify NOEXCLUSIVE to indicate that the LAN MOP downline load service can coexist with other implementations (in particular, the DECnet Phase IV implementation that operates the MOP protocol in shared mode).- size-option
SIZE=value
Use SIZE=value to specify the size in bytes of the file data portion of each downline load message. The permitted range is 246 to 1482 bytes. The default value is 246 bytes, which should allow any client to load properly. Note that some clients may not support the larger size.
The recommended size for better load performance and less server overhead is the largest size that results in successful loads of all clients. The 1482 value is derived from the maximum packet size for CSMA/CD (Ethernet) of 1518 bytes less the 802e header and CRC (26 bytes) and MOP protocol overhead (10 bytes).
You can override the size on a per-node basis. See the DEFINE NODE and SET NODE commands for details.- knownclientsonly-option
KNOWNCLIENTSONLY
NOKNOWNCLIENTSONLY (default)
Specify KNOWNCLIENTSONLY to indicate that MOP downline load requests should be serviced only for clients defined in the LAN permanent node database. When NOKNOWNCLIENTSONLY is selected, LANACP searches the LAN$DLL directory for any images requested by clients that are not defined in the LAN permanent node database./EARLY (default)
/NOEARLY
Enables Early Token Release on the device. The /NOEARLY qualifier, disables Early Token Release./ELAN
On Alpha systems, the /ELAN qualifier has two values: enable and disable. With /ELAN=ENABLE along with the keyword STARTUP, the LAN emulation is loaded when LANCP starts. With /ELAN=DISABLE, the same parameters used with ENABLE can be invoked.
