Network (Hardware and Physical) Address?

» close window

The Question is:

 
How do I find out the ethernet address of a vax system? you can set it in ncp
 but you can't show it. odd.
 
Thanks
 

The Answer is :

 
  You cannot set the Ethernet hardware address in NCP, this
  address is a permanent attribute of the Ethernet controller.
 
  DECnet Phase IV does alter the Ethernet controller physical
  address, assigning a value derived from the node's DECnet
  address -- this is why you cannot have two controllers on
  the same DECnet Phase IV host connected to the same extended
  LAN, as thus configuration would involve duplicate addresses.
  (Network configurations with filtering bridges or with DECnet
  routers in the network topology "between" the DECnet Phase IV
  controllers is permitted.)
 
  The DECnet Phase IV physical address uses AA-00-04-00.ll.hh,
  where hhll is the word value of the DECnet node.  DECnet node
  19.22 (hexadecimal 4C16) would thus be assigned the physical
  address AA-00-04-00-16-4C.
 
  DECnet-Plus does not alter the controller's physical address.
 
  As for determining the network controller's hardware address,
  please see the OpenVMS FAQ section "MISC7. How to determine
  the network hardware address?".
