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 /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.
2.4 /COUNTERS
Displays device counters.
2.5 /DLL
/DLL or MOPDLL Displays LAN volatile device database information related to MOP downline load for the device.
2.6 /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.
2.7 /MAP
Displays the current configuration of the functional address mapping table.
2.8 /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.
2.9 /OUTPUT
/OUTPUT=file-name Creates the specified file and directs output to it.
2.10 /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.
2.11 /REVISION
Displays the current LAN driver and device revision information, if available or applicable. Not all LAN drivers maintain revision information.
2.12 /SR_ENTRY
Displays the contents of the current Token Ring source routing cache table.
2.13 /TRACE
Displays LAN driver trace data.
2.14 /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 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.
