Protocol) VLAN Registration Protocol) packets that contain the configuration information and displays the configured tags. The switch periodically sends GVRP packets to provide VLAN configuration information in compliance with the IEEE 802.1Q specification. If GVRP is not configured on the switch, or if the LAN device is not connected to a switch, this command displays only the list of tags that the VLAN driver has configured. 4 Examples 1.LANCP> SHOW DEVICE/COUNTERS EXA0 Device Counters EXA0: Value Counter ----- ------- 259225 Seconds since last zeroed 5890496 Data blocks received 4801439 Multicast blocks received 131074 Receive failure 764348985 Bytes received 543019961 Multicast bytes received 3 Data overrun 1533610 Data blocks sent 115568 Multicast packets transmitted 122578 Blocks sent, multiple collisions 86000 Blocks sent, single collision 189039 Blocks sent, initially deferred 198120720 Bytes sent 13232578 Multicast bytes transmitted 7274529 Send failure 0 Collision detect check failure 0 Unrecognized frame destination 0 System buffer unavailable 0 User buffer unavailable This command displays counters for Ethernet device EXA0. 2.LANCP> SHOW DEVICE/MAP ICA0 Multicast to Functional Address Mapping ICA0: Multicast address Functional Address Bit-Reversed ----------------- ------------------ ------------ 09-00-2B-00-00-04 03-00-00-00-02-00 C0:00:00:00:40:00 09-00-2B-00-00-05 03-00-00-00-01-00 C0:00:00:00:80:00 CF-00-00-00-00-00 03-00-00-08-00-00 C0:00:00:10:00:00 AB-00-00-01-00-00 03-00-02-00-00-00 C0:00:40:00:00:00 AB-00-00-02-00-00 03-00-04-00-00-00 C0:00:20:00:00:00 AB-00-00-03-00-00 03-00-08-00-00-00 C0:00:10:00:00:00 09-00-2B-02-00-00 03-00-08-00-00-00 C0:00:10:00:00:00 09-00-2B-02-01-0A 03-00-08-00-00-00 C0:00:10:00:00:00 AB-00-00-04-00-00 03-00-10-00-00-00 C0:00:08:00:00:00 09-00-2B-02-01-0B 03-00-10-00-00-00 C0:00:08:00:00:00 09-00-2B-00-00-07 03-00-20-00-00-00 C0:00:04:00:00:00 09-00-2B-00-00-0F 03-00-40-00-00-00 C0:00:02:00:00:00 09-00-2B-02-01-04 03-00-80-00-00-00 C0:00:01:00:00:00 09-00-2B-02-01-07 03-00-00-02-00-00 C0:00:00:40:00:00 09-00-2B-04-00-00 03-00-00-04-00-00 C0:00:00:20:00:00 09-00-2B-02-01-00 03-00-00-00-08-00 C0:00:00:00:10:00 09-00-2B-02-01-01 03-00-00-00-10-00 C0:00:00:00:08:00 09-00-2B-02-01-02 03-00-00-00-20-00 C0:00:00:00:04:00 03-00-00-00-00-01 03-00-00-00-00-01 C0:00:00:00:00:80 03-00-02-00-00-00 03-00-02-00-00-00 C0:00:40:00:00:00 This command displays mapping information for Token Ring device ICA0. 3.LANCP> SHOW DEVICE/MOPDLL Device Listing, volatile database: --- MOP Downline Load Service Characteristics --- Device State Access Mode Clients Data Size ------ ----- ----------- ------- --------- EXA0 Enabled Exclusive KnownClientsOnly 1400 bytes FXA0 Disabled NoExclusive NoKnownClientsOnly 246 bytes This command displays MOP downline load information in the LAN volatile device database for all known devices. 4.LANCP> SHOW DEVICE/MOPDLL EXA0 Device Listing, volatile database: --- MOP Downline Load Service Characteristics --- Device State Access Mode Clients Data Size ------ ----- ----------- ------- --------- EXA0 Enabled Exclusive KnownClientsOnly 1400 bytes This command displays MOP downline load information in the LAN volatile device database for device EXA0. 5.LANCP> SHOW DEVICE/PARAMETERS IRA0 Device Parameters IRA0: Value Parameter ----- --------- Normal Controller mode External Internal loopback mode 00-00-93-58-5D-32 Hardware LAN address Token Ring Communication medium Enabled Functional address mode No Full duplex enable No Full duplex operational 16 Line speed (megabits/second) 16 Mbps Ring speed STP Line media Enabled Early token release Disabled Monitor contender 200 SR cache entries 2 SR discovery timer 60 SR Aging Timer Enabled Source routing 3 Authorized access priority AA-00-04-00-92-FF Upstream neighbor 0 Ring number This command displays status and parameters information for Token ring device IRA0. 6.LANCP> SHOW DEVICE/REVISION EWF0 Device Revisions EWF0: Value Component ----- --------- 02000041 Device hardware revision 08020110 00000004 Port driver revision 08020172 00000001 LAN common routines revision This command displays revision information for Ethernet device EWF0:. 7.LANCP> SHOW DEVICE/SR_ENTRY ICA0 Source Routing Cache Table ICA0: LAN address State XmtTmo RcvTmo StaleTmo DiscvTmo ----------------- ----- -------- -------- -------- -------- AA-00-04-00-92-FF LOCAL 00000028 00000028 00000245 00000000 This command displays source routing entry information for Token Ring device ICA0. 3 DLL 4 or 5 MOPDLL Displays the current state of MOP downline load services for the system, including devices for which MOP loading is enabled and counters information. Format SHOW DLL or MOPDLL 6 Parameters None. 6 Qualifier /OUTPUT /OUTPUT=file-name Creates the specified file and directs output to it. 6 Example LANCP>SHOW DLL LAN DLL Status: EXA enabled in exclusive mode for known nodes only, data size 1482 bytes FXA disabled #Loads Packets Bytes Last load time Last loaded ------ ------- ----- -------------------- ------------ EXA 5 1675 4400620 22-SEP-2002 10:27.51 GALAXY FXA 0 0 0 On this node, there are two LAN devices, EXA (DEMNA) and FXA (DEMFA). MOP downline load service is enabled on EXA in exclusive mode. Requests are answered only for nodes that are defined in the LANACP node database. The image data size in the load messages is 1482 bytes. There have been five downline loads, the last one occurring on node GALAXY at 10:27. Finally, there are no recorded downline loads for FXA, which is currently disabled for downline load service. 3 LOG Displays recent downline load activity (the last 2048 bytes of log data written to the log file SYS$MANAGER:LAN$ACP.LOG). Format SHOW LOG 4 Parameters None. 4 Qualifier /OUTPUT /OUTPUT=file-name Creates the specified file and directs output to it. 4 Example LANCP> SHOW LOG This command displays the last 2048 bytes of log data written to the log file SYS$MANAGER:LAN$ACP.LOG. 3 NODE Displays information in the LAN volatile node database. Format SHOW NODE node-name 4 Parameter node-name Specifies the name of a node in the LAN volatile node database. The name can include up to 63 characters associated with the node address. If you do not specify a node name, all nodes are displayed. 4 Qualifiers /ALL Displays information 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. /OUTPUT /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. /TOTAL Display counter totals only, for the nodes selected. 4 Examples 1.LANCP> SHOW NODE Node Listing: GALAXY (08-00-2B-2C-51-28): MOP DLL: Load file: APB.EXE Load root: $64$DIA24: Boot type: Alpha 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 command issued on a local node on which there are three nodes defined (GALAXY and CALPAL). CALPAL has issued two load requests: o The first request is the multicast request from CALPAL that the local node volunteered to accept. o 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. 2.LANCP> SHOW NODE VAXSYS Displays node characteristics and counters information from the LAN volatile node database for node VAXSYS. 3.LANCP> SHOW NODE/ALL VAX Displays node characteristics and counters information from the LAN volatile node database for all nodes whose name begins with VAX. 4.LANCP> SHOW NODE/ALL Displays node characteristics and counters information from the LAN volatile node database for all nodes. 5.LANCP> SHOW NODE/ALL/OUTPUT=TMP.INI Writes a list of all nodes to the file TMP.INI. 2 SPAWN Creates a subprocess of the current process. The SPAWN command copies the context of the subprocess from the current process. Format SPAWN [command-string] 3 Parameter command-string A string of commands to be executed in the context of the created subprocess. After the command string is executed, control returns to LANCP. 3 Qualifiers None. 3 Example LANCP> SPAWN $ MC LANCP LANCP> DEFINE NODE BOOM/ROOT=LAVC$SYSDEVICE: LANCP> SPAWN SEARCH LAVC$SYSDEVICE:[*.SYSEXE]MOD*.DAT BOOM ****************************** LAVC$SYSDEVICE:[SYS1A.SYSEXE]MODPARAMS.DAT;1 SCSNODE="BOOM " LANCP> DEFINE NODE BOOM/ROOT=LAVC$SYSDEVICE: In this example, you enter the node information for a node, but are unsure of the root, so you spawn to search MODPARAMS.DAT for the node name and then correct the root. 2 TRIGGER 3 NODE Issues a request to reboot to a remote node. Rather than specify the format to send MOP Version 3 or 4, the LANCP utility sends one message in each format to the target node. Format TRIGGER NODE node-specification 4 Parameter node-specification Supplies either the node name or the node address of the target node. If you supply the node name, the node address is obtained by looking up the node name in the LAN volatile node database. If you supply the node address, the corresponding node need not be defined in the LAN volatile node database. The canonical form of the address consists of 6 hexadecimal byte characters separated by hyphens. Use a colon as the separator character to indicate the bit-reversed form of the address. 4 Qualifiers /DEVICE /DEVICE=device-name Specifies the LAN controller device name to be used for sending the trigger boot messages. For example, you can specify a DEMNA controller as EXA, EXA0 or EXA0:. /PASSWORD /PASSWORD=16hexdigits Supplies the password to be used when the connection is initiated, in hexadecimal (for example, /PASSWORD=0123456789ABCDEF). The default password is zero. You can omit leading zeros. 4 Examples 1.LANCP> TRIGGER NODE GALAXY/DEVICE=EWA0 This command sends MOP trigger boot messages to node GALAXY using Ethernet device EWA0. 2.LANCP> TRIGGER NODE 08-00-2B-11-22-33/DEVICE=EWA0/PASSWORD=0123456789AB This command sends MOP trigger boot messages to the given node address using the Ethernet device EWA0, with indicated password. 2 UPDATE 3 DEVICE Resets a LAN device. Requires SYSPRV privilege. Format UPDATE DEVICE device-name 4 Parameter device-name Specifies a device to be reset. 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. 4 Qualifiers /RESET Specifies that the device is to be reset. 4 Example LANCP> UPDATE DEVICE EWA0/RESET Resets Ethernet device EWA0.
