I have a E9.2-1 (FT) system running under VirtualBox. First build was with a simple EIA0 configured in TCPIP as IE0 and all worked as expected. Then I tried to switch this to a failover device.
MC LANCP DEFINE LLA0 /FAIL=EIA0 /ENAB
<reboot>
From console, stop TCPIP (SYS$STARTUP:TCPIP$SHUTDOWN) and then use TCPIP$CONFIG to remove IP address from IE0 and reconfigure under LL0.
<reboot>
Has always worked for me in the past and yes, the LLA0 device is "up" with the EIA device also showing as "up" and "active". But no comms. Ping out to default gateway no working, same for inbound.
Reverse procedure back to original EIA0 and IE0 combination and it's all working again.
Am I missing something? Have always set this up so underlying device name changes can be easily fixed without reconfiguring DECnet (back in the day), TCPIP, LAT etc.
LAN failover device doesn't appear to work

Re: LAN failover device doesn't appear to work
VirtualBox network adapter "Promiscuous Mode" setting is required when you configure Lan Failover device LLxx.

Re: LAN failover device doesn't appear to work
VirtualBox Network Promiscuous mode 'Allow VM' also seems to work.
As DECnet IV addressing and LAN failover sets both add MAC addresses then it makes sense that some way of receiving data to multiple MAC addresses is required,
