Configuring DE500 Fast Ethernet NIC with TCP/IP?

» close window

The Question is:

 
We are trying to establish a TCP/IP connection between an Alpha 4100 and an
IBM ThinkPad via a switch/hub and a DE450 or a DE500 NIC. (We have tried
both !)
The green 'Link' LED is lit and the amber 'Activity' LED flashes very
briefly every 7 - 10 seconds.
Invoking 'tcpip ping' fails with the error message 'no route available'.
Using the Visio package on the ThinkPad to ping the Alpha also results in
failure.
 
We believe that we have not configured the NIC correctly for TCP/IP. The
DE450 works fine to support user terminals via DECNet.
 
Could you please direct us to documentation that will detail the TCP/IP
configuration necessary.
 
Thank you very much

The Answer is :

 
  TCP/IP Services configures the adapter correctly entirely automatically
  when the TCPIP$CONFIG tool is used -- as far as the host software is
  concerned.  Information on configuring TCP/IP Services is included in
  the TCP/IP Services documentation, available in hardcopy and at the
  OpenVMS website:
 
    http://www.openvms.digital.com:8000/
 
  If the other system uses DHCP, TCP/IP Services V5.0 and later can act
  as a DHCP Server.  See other discussions here in Ask The Wizard for
  further information on operating in DHCP environments.
 
  The OpenVMS Wizard will assume that the green LED is illuminated on both
  the DE500 and the DE450 NIC, and that the reference to DECnet indicates
  that DECnet is operating on both NICs in the current system configuration,
  and not these NICs in some previous or difference system configuration.
 
  That the green LED is is illuminated and the amber LED is flashing would
  indicate that the NIC is functioning correctly.  Given that DECnet is
  operating, the OpenVMS NIC device driver and the physical network also
  appear to be fully operational.
 
  The only host configuration settings required indicate to the NIC driver
  which interface to use (twisted pair, in this case), which speed to use,
  and the duplex mode to select.  Again, that DECnet works indicates that
  the NIC is configured correctly and operating.
 
  For additional assistance with this, please contact your software support
  organization, your switch/hub support organization, or the Compaq Customer
  Support Center.
