macShow
The macShow command displays the media access control (MAC) address
for the Ethernet interface, as the following example shows.
Router > macShow
Enet MAC Address: 0.60.45.d.0.80
value = 33 = 0x21 = ©!©

mapShowDatabase
The SDG Router maintains a database of attached devices to ensure that
each time a host attaches to the SDG Router, the target devices are seen at
a consistent address. The database lists not only the devices presently
connected, but also devices that were previously connected. If a previously
attached device is later reattached, it is assigned its previous address. Use
the mapShowDatabase command to display the persistent device map
table.

The following list describes the example fields:
devId The index of the device in the database
Type The type of interface where the device is connected. SNA indicates an
internal device. SCSI or fibre channel indicate I/O interfaces.
Chan The channel number of the interface where the device is attached
tId Target ID mapping for SCSI initiators
tLun Target LUN mapping for SCSI initiators
UID For a fibre channel interface, the unique ID of the device. For SCSI
interface, the unique ID of the SDG Router.
mapShowDevs
The SDG Router maintains a cross-reference map of device addresses. You
can display Information about the presently attached and available devices
in the map by using the mapShowDevs command.
