rx2660 lancp full duplex enabled but not operational

My Integrity rx2660 VMS 8.3 system with eia0 is connected to a 100 full duplex switch port. Through lancp I can turn off autonegotiate, but the full duplex will not go operational even though it is enabled. Should/Can this be set in the console like Alpha's? Is there another 'duplex operational' lancp parameter?
How do I make full duplex operational?

Re: rx2660 lancp full duplex enabled but not operational

There is not a way to set this at the console.
The system will boot with eia0 set to autonegotiate. You then change it using

LANCP SET DEVIC EIA0:/NOAUTONEG/FULL/SPEED=100

and check it using
LANCP SHOW DEVICE EIA0/CHAR
LANCP SHOW DEVICE EIA0/INT

Jerry,

and you can define the device characteristics in the LANCP permanent device database with:

LANCP> DEFINE DEVICE EIA0:/SPEED=100/NOAUTO

Then you don't have to execute a LANCP SET command every time during startup...

I will define the characteristics. Thanks

Re: rx2660 lancp full duplex enabled but not operational

Standard rant:

The developer within VMS Engineering who writes and maintains the LAN drivers has repeated stated both ends of a LAN connection (the switch and the NIC) should be set to
autonegotiation enabled, assuming a modern version of VMS and a modern switch. Any version of VMS running on an Itanium would be considered "modern" for this purpose.

If this doesn't result in a fully-duplexed 100 Mb/S connection, then there's likely a hardware problem somewhere
