  DECserver and DECnet? 
 The Question is:
 
How do Decserver300 Terminal servers load from a
Decnetplus V host? We upgraded recently on a
test LAN and it seems to work but we do not know
how or why? We are running DS300 V2.2c and will
upgrade our Live LAN soon and want to be sure
Live servers will also work.
 
 
 The Answer is:
 
  Terminal servers and other similar network devices request downloads
  and maintenace operations via the Maintenace and Operations Protocol
  (MOP) protocol.  MOP is traditionally thought of as part of a DECnet
  implementation, but it is also available on hosts not using DECnet.
 
  Outside of maintenance-related functions (download requests, upline
  dump requests, remote console access), LAT devices do not typcally
  use MOP protocols -- in particular, the LAT protocol is completely
  unrelated to DECnet.
 
  MOP service requests can be processed by DECnet Phase IV hosts, by
  DECnet-Plus (formerly known as DECnet/OSI) hosts, and by LANCP.  The
  OpenVMS Wizard typically recommends LANCP, as it avoids dependence
  on any particular network transport -- it works with DECnet Phase IV,
  with DECnet-Plus, and with TCP/IP Services.
 
  LANCP is available in OpenVMS V6.2 and later.
