[comp.protocols.tcp-ip] DEC Ethernet addresses

KVC@ENGVAX.SCG.HAC.COM (Kevin Carosso) (08/13/87)

For VMS DECnet (using NCP):

to show the ethernet controller's hardware address:

---------------------------------------------------------------------
NCP> SHOW LINE UNA-0 CHARACTERISTICS
Line Volatile Characteristics as of 12-AUG-1987 16:06:40

Line = UNA-0

Receive buffers          = 6
Controller               = normal
Protocol                 = Ethernet
Service timer            = 4000
Hardware address         = 08-00-2B-05-D3-E3
Device buffer size       = 1498
---------------------------------------------------------------------


to show the ethernet controller's current address as set by DECNet:

---------------------------------------------------------------------
NCP> SHOW EXECUTOR STATUS
Node Volatile Status as of 12-AUG-1987 16:06:10

Executor node = 45.9 (ENGVAX)

State                    = on
Physical address         = AA-00-04-00-09-B4
---------------------------------------------------------------------

This is the one generated by DECnet from the node number via the
scheme: (area * 1024) + node = last_two_bytes

There seems to have been some confusion on these issues.

Also, I've noted that my DELUA controller and the DESVA controller in a
VAXstation-2000 have hardware addresses assigned in the group 08-00-2B.
I guess DEC got more than the AA-00-00 through AA-00-04 range.
