OpenVMS System Management Utilities Reference Manual

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 ATMworks 350 is: HC n0, where n is the controller number. An example of the parent device for ATMworks 750 is: HW n0, 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.

/FULL_DUPLEX

/NOFULL_DUPLEX (default)

The /NOFULL_DUPLEX qualifier, disables full-duplex operation.

/MAP=(MULTICAST_ADDRESS=address, FUNCTIONAL_ADDRESS=address)

/NOMAP=(MULTICAST_ADDRESS=address)

The /NOMAP=(MULTICAST_ADDRESS=address) qualifier, clears the mapping established for the specified address.

Specify the functional address as follows:

• The MULTICAST_ADDRESS argument requires a standard 6-byte multicast address.
• The FUNCTIONAL_ADDRESS argument requires only the last 4 bytes of the functional address (the preceding 03-00 bytes are automatically prefixed).
• The address variable, given as hexadecimal byte characters separated by hyphens, specifies the canonical form of the address. Use a colon as the separator character to indicate the bit-reversed form of the address.

For example, to map the multicast address CB-00-01-02-03-04 to the functional address 03-00-00-80-00-00 on the Token Ring device IRA0, enter the following command:

SET DEVICE IRA0/MAP=(MULTI=CB-00-01-02-03-04,FUNCT=00:01:00:00)

For the default address mapping, see Table 12-1 or issue the command SHOW DEVICE/MAP device-name.

/MAX_BUFFERS=value

/MEDIA=value

• For Token Ring devices:
  Selects the type of cable media used to connect the adapter to the Token Ring Media Access Unit (MAU) for devices that do not automatically detect this. Acceptable values for this are either unshielded twisted pair (UTP) or shielded twisted pair (STP). The default value is STP.
• For Ethernet devices:
  Selects the cable connection. Normally, the selection is made during device initialization using a limited autosensing algorithm that selects twisted pair, but fails over to AUI (Attachment Unit Interface) if twisted pair does not appear to be functional. Thereafter, a cabling change would require a reboot of the system to take effect. This command allows you to change the selection without rebooting.
  Acceptable values are AUI (10Base2, 10Base5), TWISTEDPAIR (10BaseT), and AUTOSENSE (reperform the limited autosense algorithm). The default value is AUTOSENSE.
  Some devices, such as the DE435, require a jumper change on the Ethernet card to switch between 10Base2 and 10Base5 (thinwire and thickwire). Other devices, such as the DE434, DE436, and DE500, have only twisted pair connections.

/MIN_BUFFERS=value

/PERMANENT

/PERMANENT_DATABASE

/PVC=(vci[,...])

/[NO]PVC=(vci[,...])

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 switch to be used.

The vci is the VCI (Virtual Channel ID) of the PVC (Permanent Virtual Connection) to be used.

/RING_PURGER

/SOURCE_ROUTING (default)

/NOSOURCE_ROUTING

/SPEED=value

For Token Ring, valid values are either 4 or 16, indicating 4 megabits per second or 16 megabits per second. The default value for Token Ring is 16, unless the LAN adapter supports a nonvolatile mechanism for setting this parameter (as does the DEC Token Ring Controller 700).

For Ethernet, valid values are either 10 or 100, which selects the 10 megabits per second Ethernet port or the 100 megabits per second Fast Ethernet port. The default for Ethernet is to sense automatically which type of port is connected and select the appropriate speed.

/SR_ENTRY=(LAN_ADDRESS=address, RI=routing-information)

/NOSR_ENTRY=(LAN_ADDRESS=address)

Use this qualifier only as a last resort when isolating communication failures on extended LAN topologies.

The /NOSR_ENTRY=(LAN_ADDRESS=address) qualifier, clears the previously defined static source routed route.

The address is a standard 6-byte LAN address (given as hexadecimal byte characters separated by hyphens), which specifies the canonical form of the address. Using a colon as the separator character indicates the bit-reversed form of the address.

The routing-information is the source routing field, specified as a series of two-byte hexadecimal characters (each byte separated by a hyphen). The field consists of a two-byte routing control field followed by up to 14 two-byte segment identifiers, each containing the ring number and the bridge number used in the hop.

/TOKEN_ROTATION

/TOKEN_TIMEOUT

/TRANSMIT_TIMEOUT

/UPDATE

Examples

1. LANCP>SET DEV CLA/CLIP=CREATE LANCP>SET DEV CLA/CLIP=(TYPE=CLIENT,PARENT=HWA) LANCP>SET DEV CLA/CLIP=(IP_ADDR=132.1.1.20,IP_SUB=255.255.255.0) LANCP>SET DEV CLA/PVC=100 LANCP>SET DEV CLA/CLIP=ENABLE

A CLIP client is created using PVC 100. Note that an ATM ARP server is not necessary for a client with a PVC.

2. 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.

3. LANCP> SET DEVICE/MEDIA=TWI EWB0
 
      

Sets the media type to twisted pair for the second Tulip Ethernet device, EWB0.

4. LANCP> SET DEVICE EXA0/MOPDLL=ENABLE
 
      

Enables MOP downline load service for device EXA0, leaving the remaining MOPDLL parameters unchanged.

5. 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.

6. LANCP> SET DEVICE EXA0/MOPDLL=(ENABLE,NOEXCLUSIVE)
LANCP> SET DEVICE FXA0/MOPDLL=(ENABLE,EXCL,KNOWN)
      

These commands enable LANACP MOP downline load service for:

• LAN device EXA0 in nonexclusive mode
• LAN device FXB0 in exclusive mode for only known clients

Enters a node into the LAN volatile node database or modifies an existing entry. Requires SYSPRV privilege.

Format

SET NODE node-name

Parameter

node-name

Supplies the name of a node to be added to the LAN volatile 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.

Qualifiers

/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 volatile 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:

• VAX_SATELLITE---a VAX satellite cluster boot
• ALPHA_SATELLITE---an Alpha satellite cluster boot
• OTHER---the specified image; noncluster satellite loads that do not require additional data

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.

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, 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.

/PERMANENT_DATABASE

Updates the node entries in the LAN volatile node database with any data currently set in the permanent database. This allows you to update the volatile database after changing data in the permanent database, rather than repeating the commands for each updated entry to apply the changes to the volatile database.

/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 to load that have a problem with MOP Version 4 booting. 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.

Examples

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

This command sets up node VAXSYS for booting as an Alpha satellite into the 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> SET NODE VAXSYS/ADDRESS=08-00-2B-11-22-33 - 
                      /FILE=NISCS_LOAD.EXE - 
                      /ROOT=$64$DIA14:<SYS10.> - 
                      /BOOT_TYPE=VAX_SATELLITE
 
      

This command sets up node VAXSYS for booting as a VAX satellite into the 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> SET NODE VAXSYS/ADDRESS=08-00-2B-11-22-33/NOROOT
 
      

This command changes the LAN address associated with node VAXSYS and clears the current root specification.

SET 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 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.

SHOW CONFIGURATION

Displays a list of LAN devices and characteristics on the system.

Format

SHOW CONFIGURATION

Parameters

None.

Qualifiers

/OUTPUT=file-name

Creates the specified file and directs output to it.

/USERS

On Alpha systems, shows which protocols are using which template device.

Example

LANCP> SHOW CONFIGURATION
LAN Configuration: 
   Device   Medium      Default LAN Address   Version 
   ------   ------      -------------------   ------- 
    EWA0    CSMA/CD      08-00-2B-E4-00-BF    02000023 
    EWB0    CSMA/CD      08-00-2B-92-A4-0D    02000023 
    IRA0    Token Ring   00-00-93-58-5D-32    20000223 
 
      

This example shows the output from a SHOW CONFIGURATION command that was entered on a node that has three LAN devices, two DE435s, and a DETRA.

The version is the device-specific representation of the actual (hardware or firmware) version. In this example, for two devices on the PCI bus, the actual version is in the low byte (2.3 for the DE435 adapters). A device that does not have a readable version is shown as version zero.

Consult your device-specific documentation to correlate the version returned with a particular hardware or firmware implementation of the device.
