The /NOFULL_DUPLEX qualifier disables full-duplex operation.
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.
Valid values are 10, 100, 1000, 10000, or autonegotiate; the last choice, autonegotiate, selects the 10 Mb/s for Ethernet, 100 Mb/s for Fast Ethernet, 1000 Mb/s for Gigabit Ethernet, and 10000 Mb/s for 10-Gigabit Ethernet. If you select autonegotiate, the LAN driver repeats autonegotiation.
/DISABLE
Disables the devices in a LAN Failover set. When disabled, LAN devices can be added to or deleted from the Failover set./ENABLE
Enables a Failover set, which activates the Logical LAN device. The LAN Failover driver selects a LAN device from the LAN Failover set as the active device and then allows I/O to the Logical LAN device./FAILOVER_SET=(device-name[,...])
/[NO]FAILOVER_SET=(device-name[,...])
Specifies the members of a LAN Failover set./PRIORITY=value
Sets the failover priority of a LAN device. Priority is given to the LAN failover device with the highest priority when choosing the active LAN device. When a LAN device with a higher priority becomes available, a failover transition to the newly available device is performed. This allows a system manager to set a preferred device by setting one LAN device to a higher priority than others. The LAN failover driver uses the preferred device when it is available./SIZE=value
Sets the packet size of the LAN failover device.Valid values are STANDARD (the default) or JUMBO:
- STANDARD is the Ethernet maximum packet size of 1518 bytes.
- JUMBO is the oversize packet size available with Gigabit Ethernet devices.
JUMBO is allowed only if all the LAN devices in the LAN failover set are Gigabit devices.Note that the size specified for the LAN failover device overrides the size set on the members of the LAN failover set; that is, the JUMBO frame setting of a LAN device is of no consequence when the size is determined for the LAN failover device.
/SWITCH (SET DEVICE only)
Forces a LAN failover to another member of the LAN failover set.You can test LAN failover operation by using this command to switch from one device to another.
/RING_PURGER
Enables the ring purger process of the FDDI device./TOKEN_ROTATION
Sets the requested token rotation time for the FDDI ring./TOKEN_TIMEOUT
Sets the restricted token timeout time for the FDDI ring./TRANSMIT_TIMEOUT
Sets the valid transmission time for the FDDI device.
/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.
/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.
/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.
/EARLY (default)
/NOEARLY
Enables Early Token Release on the device. The /NOEARLY qualifier, disables Early Token Release./MAP=(MULTICAST_ADDRESS=address, FUNCTIONAL_ADDRESS=address)
/NOMAP=(MULTICAST_ADDRESS=address)
Maps a standard multicast address to a functional address. Token ring devices do not support IEEE 802 standard globally defined group addresses. They do support functional addresses. A functional address is a locally administered group address that has 31 possible values. Each functional address sets one bit in the third through sixth byte of the address and bytes 1 and 2 are 03-00 (C0:00 in bit reversed format).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 13-1 or issue the command SHOW DEVICE/MAP device-name.

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./SOURCE_ROUTING (default)
/NOSOURCE_ROUTING
Enables source routing on the Token Ring device. If you only have one ring in your LAN or you use transparent bridging, use the /NOSOURCE_ROUTING qualifier to turn off source routing./SPEED=value
Sets the speed of the Token Ring LAN.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.
/SR_ENTRY=(LAN_ADDRESS=address, RI=routing-information)
/NOSR_ENTRY=(LAN_ADDRESS=address)
Statically defines a specific source-routed route for a specific node. The default value is no routes specified. This caching remains valid while used or until the aging timer expires.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.
/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)/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. /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: HW n0, where n is the controller number. An example of the parent device for DGLTA is: HC 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. /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.

Enters a node into the LAN volatile node database or modifies an existing entry. Requires SYSPRV privilege.
SET NODE node-name
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.
/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: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---a VAX satellite cluster boot
- ALPHA_SATELLITE---an Alpha satellite cluster boot
- I64_SATELLITE---an OpenVMS Cluster Integrity servers satellite boot
- OTHER---the specified image; noncluster satellite loads that do not require additional data
If you do not specify the /BOOT_TYPE qualifier, the setting remains unchanged. The /NOBOOT_TYPE qualifier clears the field.
Note that Integrity server satellites boot using TFTP rather than MOP services. This boot type is included so that the information in the node database can be maintained, not because it is needed for booting purposes.
/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 (SET NODE only)
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.
/VOLATILE_DATABASE (DEFINE NODE only)
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.
