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
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 – Qualifiers
2.1 /ALL
Shows all devices that match device name.
2.2 /CHARACTERISTICS
/CHARACTERISTICS or PARAMETERS
Displays status and related information about the device.
2.3 /COUNTERS
Displays device counters.
2.4 /DLL
/DLL or MOPDLL
Displays LAN volatile device database information related to MOP
downline load for the device.
2.5 /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.
2.6 /MAP
Displays the current configuration of the functional address
mapping table.
2.7 /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.
2.8 /OUTPUT
/OUTPUT=file-name
Creates the specified file and directs output to it.
2.9 /REVISION
Displays the current LAN driver and device revision information,
if available or applicable. Not all LAN drivers maintain revision
information.
2.10 /SR_ENTRY
Displays the contents of the current Token Ring source routing
cache table.
2.11 /TRACE
Displays LAN driver trace data.
2.12 /VLAN
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 (GARP (Generic Attribute Registration
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.
