We want to change the Device used by DecNet from EWA0 to LLB0. Fisrt we have created the device LLB with LANCP but after!...
Is anybody know a easy way to do that thing ?
We run Alpha OpenVMS V8.3 on a 5 node Cluster.
Thanks.

Solutionyou're running DECnet-Plus, so you need NCL not NCP.
A simple 'trick' would be to edit SYS$MANAGER:NET$CSMACD_STARTUP.NCL and just replace the string 'EWA' with 'LLB'.
The 'correct' way to change the CSMA-CD device name is via:
$ @SYS$MANAGER:NET$CONFIGURE ADVANCED
...
[3] Configure Devices on this machine
...
and answer NONE for all devices, on which you do NOT want to run DECnet. Wait until LLB0 shows up and provide the CSMACD-n answer for the Data Link Name to use.
Check with MC NCL SHOW CSMA-CD STAT * ALL for the mapping between CSMA-CD Stations and E* or L* devices.
BTW, why are you using LLB instead of LLA ?

Re: DecNet Changing NIC from EWA0 to LLB0
note that you have to restart DECnet to activate this change. Consider to boot the system to have a clean start of DECnet-Plus.

Re: DecNet Changing NIC from EWA0 to LLB0
On all node of the Cluster, the interface EWB0 and EWD0 are used for the Cluster communication, SCS, DecNet etc...
We use differents switchs to connect those interfaces, this private LAN is extended over 3 site!
Currently we are in the transition of extending the private LAN.

Re: DecNet Changing NIC from EWA0 to LLB0
About Non Single Point Of Failure (NSPOF) with DecNet and NetWork Interface Card, and for those who have a long experience with DecNet, what is the prefered way to get NSPOF on a node?
1) Configuring 2 differents NIC with DecNet
2) Using LAN_FAILOVER
For the same node, the 2 NIC are on 2 differents switchs but in the same private VLAN.
