The Question is: I was asked to see if the communication from the Alpha (which I manage) to the switch on the network (managed by the network guys) be made full duplex. ifconfig displays it is working in simplex mode and there does not seem to be an option in ifconfig to change it. The switch (CISCO) is set to "auto-negotiate" It is also communicating at 10mbps, Can this be changed to 100mbps? The network card is a DE500 capable of both 10/100mbps operation Platform and software details: Compaq TCP/IP Services for OpenVMS Alpha Version V5.1 on a AlphaServer 1200 5/533 4MB running OpenVMS V7.1-2 TCPIP> ifconfig -a LO0: flags=100c89<UP,LOOPBACK,NOARP,MULTICAST, SIMPLEX,NOCHECKSUM> inet 127.0.0.1 netmask ff000000 ipmtu 4096 TN0: flags=80<NOARP> WE0: flags=c43<UP,BROADCAST,RUNNING,MULTICAST, SIMPLEX> inet 156.149.72.244 netmask ffff0000 broadcast 156.149.255.255 ipmtu 1500 The Answer is : Please see the OpenVMS FAQ section on Ethernet, IEEE 802.3, CSMA/CD negotiation and specifically on DE500 controller configuration. There are multiple DE500 controller variants available, and the FAQ covers this particular topic in some detail.
