| 1 - CONFIGURATION |
Displays a list of LAN devices and characteristics on the system.
Format
SHOW CONFIGURATION
1.1 - Parameters
None.
1.2 - Qualifiers
1. 2.1 - /OUTPUT
/OUTPUT=file-name
Creates the specified file and directs output to it.
1. 2.2 - /USERS
On Alpha systems, shows which protocols are using which template
device.
1.3 - 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.
| 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
2.1 - Parameter
device-name
Supplies the LAN controller device name. 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.
For example, you can specify a DEMNA controller as EXA, EXA0,
or EXA0:. This refers to the LAN template device, for which is
maintained most of the device parameters and counters. Also,
the device name can refer to a device unit representing an
actual user or protocol. For example, the cluster protocol can
be started on a device as EWA1. You can specify specific device
units to view unit-specific parameter information.
If you do not specify a device name, all devices are displayed.
If you specify a device name, all matching LAN devices are
displayed, for example: E to select all Ethernet devices, F
for FDDI, I for Token Ring, EW to select all Ethernet PCI Tulip
devices.
NOTE
If you do not specify a qualifier, the utility displays the
matching devices without additional information.
2.2 - Qualifiers
2. 2.1 - /ALL
Shows all devices that match device name.
2. 2.2 - /CHARACTERISTICS
On Alpha systems, same as the /PARAMETERS qualifier.
2. 2.3 - /COUNTERS
Displays device counters.
2. 2.4 - /DLL
Displays LAN volatile device database information related to MOP
downline load for the device.
2. 2.5 - /MAP
Displays the current configuration of the functional address
mapping table.
2. 2.6 - /MOPDLL
Same as the /DLL qualifier.
2. 2.7 - /OUTPUT
/OUTPUT=file-name
Creates the specified file and directs output to it.
2. 2.8 - /PARAMETERS
Displays status and related information about the device.
2. 2.9 - /REVISION
Displays the current firmware revision of the device, if
available or applicable. Not all LAN devices return revision
information. LAN devices that do not have a revision display a
revision of zero.
2. 2.10 - /SR_ENTRY
Displays the contents of the current Token Ring source routing
cache table.

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.
| 4 - 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
4.1 - Parameters
None.
4.2 - Qualifier
4. 2.1 - /OUTPUT
/OUTPUT=file-name

This example shows output from a command issued on a local node
on which there are three nodes defined (GALAXY, ZAPNOT, 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
