  Multiple Ethernet cards? 
 The Question is:
 
Hardware:  2 Alpha server4000+HSZ50
Software: OpenVMS 7.1-1h2
Symptom:
   Each computer have 2 DE500 ehternet adapter,
each DE500 have a UCX address and a cluster_alias address.  And they are not
in the same LAN segment. We found we can ping one cluster_alias address, but
we can't ping another cluster_alias address. We still can ping the true
address of the adapter.
  And we find the DECnet PhaseIV only run on one of the DE500. by typing
following command:
 
  NCP&gt;show k circuits
 
  it show only EWA-0, not the EWA-0 and EWB-0.
 
  Please tell me how to resolve this problem.
 
 
 
 The Answer is:
 
  Please upgrade to the OpenVMS Alpha V7.1-2 or V7.2-1 release (or
  later), with the current associated ECO kits installed.
 
  DECnet Phase IV on OpenVMS Alpha is an end-node implementation, and
  operates solely on one interface.
 
  DECnet-Plus receives on multiple interfaces, but only transmits on
  multiple interfaces when host-based routing is enabled.
 
  As for PING, please see topic 3015 for a discussion of subnets and
  the general operation of PING with multiple network controllers.
 
  If these do not answer the specific question(s), please contact the
