HP OpenVMS System Analysis Tools Manual
SHOW KNOWN_FILE_ENTRY
See SHOW KFE.
SHOW LAN
Displays information contained in various local area network (LAN) data
structures.
Format
SHOW LAN [/qualifier[,...]]
Parameters
None.
Qualifiers
/ATM
Specifies that asynchronous transfer mode (ATM) information for the LAN
be displayed.
/CLIENT=name
Specifies that information be displayed for the specified client. Valid
client designators are SCA, DECNET, LAT, MOPRC, TCPIP, DIAG, ELN, BIOS,
LAST, USER, ARP, MOPDL, LOOP, BRIDGE, DNAME, ENCRY, DTIME, and LTM. The
/CLIENT, /DEVICE, and /UNIT qualifiers are synonymous and mutually
exclusive.
/COUNTERS
Specifies that the LAN station block (LSB) and unit control block (UCB)
counters be displayed.
/CSMACD
Specifies that Carrier Sense Multiple Access with Collision Detect
(CSMA/CD) information for the LAN be displayed. By default, both
CSMA/CD and Fiber Distributed Data Interface (FDDI) information is
displayed.
/DEVICE=name
Specifies that information be displayed for the specified device, unit,
or client. For each LAN adapter on the system, there is one
device and multiple users of that device called,
units or clients. Device designators
are specified in the format XXdn, where
XX is the type of device, d is the
device letter, and n is the unit number. The device
letter and unit number are optional. The first unit, which is always
present, is the template unit. These are specified as indicated in this
example for a DEMNA called EX:
/DEVICE=EX---display all EX devices on the system
/DEVICE=EXA---display the first EX device only
/DEVICE=EXA0---display the first EXA unit
/DEVICE=SCA---display SCA unit
/DEVICE=LAT---display LAT units
Valid client names are listed in the /CLIENT=name qualifier.
The /CLIENT, /DEVICE, and /UNIT qualifiers are synonymous and mutually
exclusive.
/ELAN
Specifies information from an Emulated LAN (ELAN) that runs over an
asynchronous transfer mode (ATM) network. The /ELAN qualifier displays
the LAN Station Block (LSB) address, device state, and the LSB fields
pertinent to an ELAN for both the parent ATM device and the ELAN
pseudo-device drivers. It also specifies the name, description, parent
device, state, and LAN emulation client (LEC) attributes of the ELAN.
The qualifier /ELAN used with the device qualifier (/ELAN/DEVICE=ELA)
will only display information for the specified device or pseudo-device.
/ERRORS
Specifies that the LSB and UCB error counters be displayed.
/FDDI
Specifies that Fiber Distributed Data Interface (FDDI) information for
the LAN be displayed. By default, both CSMA/CD and FDDI information is
displayed.
/FULL
Specifies that all information from the LAN, LSB, and UCB data
structures be displayed.
/INTERNAL
Specifies internal counters of the drivers by displaying the internal
counters. If the /INTERNAL qualifier is used with the /DEVICE
qualifier, the /INTERNAL specifies the internal counters of a specific
driver.
/QUEUES
Specifies a listing of all queues, whether their status is valid or
invalid, and all elements of the queues. If the /QUEUES qualifier is
used with the /DEVICE qualifier, the /QUEUES specifies a specific queue.
/SOURCEROUTING
Specifies that the information in the source routing table maintained
by the Token Ring driver be displayed.
/SUMMARY
Specifies that only a summary of LAN information (a list of flags,
LSBs, UCBs, and base addresses) be printed. This is the default.
/TIMESTAMPS
Specifies that time information (such as start and stop times and error
times) from the device and unit data structures be printed. SDA
displays the data in chronological order.
/TR
Specifies that Token Ring information for the LAN be displayed.
/UNIT=name
Specifies that information be displayed for the specified unit. See the
descriptions for /CLIENT=name and /DEVICE=name
qualifiers.
/VCI
Specifies that information be displayed for the VMS Communication
Interface Block (VCIB) for each LAN device with an active VCI user. If
you use the /VCI qualifier with the /DEVICE qualifier, the VCIB is only
displayed for the specified device.
Description
The SHOW LAN command displays information contained in various local
area network (LAN) data structures. By default, or when the /SUMMARY
qualifier is specified, SHOW LAN displays a list of flags, LSBs, UCBs,
and base addresses. When the /FULL qualifier is specified, SHOW LAN
displays all information found in the LAN, LSB, and UCB data structures.
