1 SHOW 2 ACP Displays the settings of various options for LANCP and LANACP. Format SHOW ACP 3 Parameters None. 3 Qualifiers /OUTPUTFILE /OUTPUTFILE=filespec Writes command output to the specified file. 3 Example LANCP> SHOW ACP LANCP/LANACP options: Verify is OFF OPCOM messages are ENABLED DLL packet tracing is DISABLED This example shows how LANCP and LANACP are currently configured. 2 CONFIGURATION Displays a list of LAN devices and characteristics on the system. Format SHOW CONFIGURATION 3 Parameters None. 3 Qualifiers /BANDWIDTH Shows configuration and bandwidth information for each LAN device, including uptime, packets, bytes, highest bandwidth interval data. /OUTPUTFILE /OUTPUTFILE=filespec Writes command output to the specified file. /STATUS Shows configuration and status information for each LAN device, including uptime, packets, bytes, errors. /USERS Shows configuration information and the protocols running on each LAN device. 2 DEVICE Displays information in the volatile device database. If the LANACP process is not running, displays a list of current LAN devices. Format SHOW DEVICE device-name 3 Parameter device-name Specifies the LAN device name. The device name has the form ddcu, where dd is the device identifier, 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 EI Ethernet device is specified as EIA0, the second as EIB0, and so on. You can specify the first EI device, for example, as EIA, EIA0, or EIA0:. A partial device name selects all matching devices. For example: E to select all Ethernet devices, V for VLAN devices, EI for Ethernet EI devices, no device name to select all LAN devices. 3 Qualifiers /ALL Shows all devices. If you specify a device name, all matching LAN devices are displayed, for example: E to select all Ethernet devices, V for VLAN devices, EI to select all Ethernet EI devices. LIST and SHOW commands implicitly include this qualifier. /BANDWIDTH Displays bandwidth data collected. Bandwidth data is collected once a second for each LAN device. Included is a column characterizing the bandwidth as Zero, <1Mb, 1Mb ... Additional qualifiers affect what data is displayed as follows: o /EXPANDED Expands compressed data and converts the raw data into one second intervals. o /SUMMARY Provides summary data only. Summary data is collected on one-second intervals (/EXPANDED is implied). o /SINCE=time /DURATION=time /LAST=time Displays results for a period of time. SINCE defaults to TODAY and can be explicity specified as YESTERDAY or TODAY. DURATION and LAST are equivalent. DURATION or LAST defaults to 60 seconds if no value is provided. o /[NO]ZERO /1MB /10MB /100MB /1GB /2GB /5GB /10GB To select specific bandwidths, for example /100MB selects intervals with bandwidth 100 MBits/sec or greater. o /DUMPFILE Writes the binary bandwidth data to the specified output file, including the system name, LAN device name, and binary bandwidth data as read from the LAN device. Note: If more than one device is selected only the first device found is processed. o /INPUTFILE=filespec Reads the binary bandwidth data from the specified file (created by /DUMPFILE and /OUTPUTFILE) rather than from the LAN device. The default bandwidth buffer size is 2048 buckets, total 64k bytes per LAN device. System paraeter LAN_FLAGS can be adjusted for different sizes according to this table (bits 9, 10, 11): LAN_FLAGS Buckets MBytes Bytes TimeNoCompress CompressedUpTo 0x00000000 2048 1/16 65536 0.6 hrs 9 hours 0x00000200 32768 1 1048576 9.1 hrs 6 days 0x00000400 65536 2 2097152 18.2 hrs 12 days 0x00000600 98304 3 3145728 27.3 hrs 18 days 0x00000800 131072 4 4194304 36.4 hrs 24 days 0x00000A00 163840 5 5242880 45.5 hrs 30 days 0x00000C00 196608 6 6291456 54.6 hrs 36 days 0x00000E00 229376 7 7340032 63.7 hrs 42 days /CHARACTERISTICS /CHARACTERISTICS or PARAMETERS Displays status and related information about the device. /CLEAR_COUNTERS Clears device counters and internal driver counters after a SHOW DEVICE/COUNTERS or SHOW DEVICE/INTERNAL_COUNTERS command. Subsequent SHOW commands show the counter values accumulated since the clear was done. This affects counters displayed by LANCP only. See the /RESTORE_COUNTERS to restore counters to the original values. /COUNTERS Displays device counters. /DLL /DLL or MOPDLL Displays LAN volatile device database information related to MOP downline load for the device. /INTERNAL_COUNTERS Displays internal counters. By default, it does not display zero counters. To see all counters, including zero, use the additional qualifier /ZERO. To see the debug counters, use the additional qualifier /DEBUG. /MESSAGES Displays the console messages displayed by the LAN driver as part of the LAN driver internal counters. This qualifier is included for convenience, to avoid scanning the internal counters to get to the message data. /OUTPUTFILE /OUTPUTFILE=filespec Writes command output to the specified file. /RESTORE_COUNTERS Restores device counters and internal driver counters prior to a SHOW DEVICE/COUNTERS or SHOW DEVICE/INTERNAL_COUNTERS command. See the /CLEAR_COUNTERS to clear the counters. /REVISION Displays the current LAN driver and device revision information, if available or applicable. Not all LAN drivers maintain revision information. /TEST Displays test status and configuration for the test functionality built into LANCP for purposes of debug and validation. The test functionality is described in a text file on the system, SYS$HELP:LAN_COUNTERS_AND_FUNCTIONS.TXT. /TRACE Displays LAN driver trace data. Additional qualifiers affects the trace data output as follows: o /PCAPFILE=filespec Without affecting any other output, LANCP writes the transmit and receive packet trace entries to the specified file in binary PCAPNG format, version 1.0. This file can be read by other utilities that process PCAPNG files, such as WireShark. o /DUMPFILE Writes the trace data to the file specified by the /OUTPUTFILE qualifier. This file can be read using the /INPUTFILE qualifier so the data can be viewed later and with the /SELECT qualifier to select particular entries. o /INPUTFILE=filespec Reads trace data from the specified file, which was created by the /DUMPFILE qualifier. o /REVERSE Displays trace data in reverse order. o /SELECT=(mask-option, keywords) Specifies which trace events to display. You can specify the following keywords with this qualifier: o mask-option MASK=(value1,value2) Use MASK=(value1,value2) to specify the trace mask to select which entries should be displayed from the trace data. The first 32 bits consist of events common to most LAN drivers. The second 32 bits consist of events specific to the LAN driver for the device. The mask can be specified by a numerical value and/or a list of keywords that identify the bits to be set. o keywords Any event can be specified - they are listed in the trace header. o /[NO]HEADER By default, the trace masks are displayed then the trace data. To suppress this trace header data, specify /NOHEADER. To display only the trace header data, specify /HEADER. /VLANS Displays a list of IEEE 802.1Q tags that are configured on the switch port connected to the specified physical LAN device. LANCP listens for the GVRP packets that contain the configuration information and displays the configured tags. The switch periodically sends GVRP (GARP VLAN Registration Protocol) (GARP = Generic Attribute Registration Protocol) 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. 3 Examples 1 LANCP> SHOW DEVICE/COUNTERS EIA0 Device Counters EIA0: 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 the Ethernet device EIA0. 2 LANCP> SHOW DEVICE/DLL Device Listing, volatile database: --- MOP Downline Load Service Characteristics --- Device State Access Mode Clients Data Size ------ ----- ----------- ------- --------- EIA0 Enabled Exclusive KnownClientsOnly 1400 bytes EWA0 Disabled NoExclusive NoKnownClientsOnly 246 bytes This command displays MOP downline load information in the LAN volatile device database for all known devices. 3 LANCP> SHOW DEVICE/DLL EIA0 Device Listing, volatile database: --- MOP Downline Load Service Characteristics --- Device State Access Mode Clients Data Size ------ ----- ----------- ------- --------- EIA0 Enabled Exclusive KnownClientsOnly 1400 bytes This command displays MOP downline load information in the LAN volatile device database for the Ethernet device EIA0. 4 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:. 2 DLL Displays the current state of MOP downline load services for the system, including devices for which MOP loading is enabled and counters information.
