TCPIP on a LAN failover set device

[Guinaudeau]

We got a VMS V7.3-2 with TCPIP V5.4 ECO 4, and are using the 7.3-2 feature "LAN failover". Configured a device LLA combining two physical devices (Ethernet GB). That is, the machine has one unique IP address configured on interface LE0, and no failover on IP.

It worked OK with that configuration.

We need now to change the IP address of the machine. I used the TCPIP commands :

$ @SYS$STARTUP:TCPIP$SHUTDOWN
$ TCPIP SET CONFIG NOINTERFACE LE0
$ TCPIP SET CONFIG INTERFACE LE0
/HOST=...
/BROADCAST=...
/NETWORK_MASK=...

Used to do this in place of TCPIP$CONFIG menus.
Starting up the TCPIP (same after VMS reboot), error :

%TCPIP-I-DEFINTE, defining interfaces
%TCPIP-I-ACPQIO, failure on internet ACP QIO
%TCPIP-E-BADSEQUENCE, syntax error in escape sequence

$ HELP/MESS BADSEQUENCE

Explanation: A terminal escape sequence is invalid. This message is associated with a status code returned by I/O functions.

=> what is wrong with this ? any idea ?

It sounds like some side-effect of the failover set device, since this worked OK with a "simple" physical device. I restore a backup and will attempt with TCPIP$CONFIG to do this.

=> is it the issue ? any experience ?

Thanks in advance for any help

Nota : i read before opening this thread :

but IP on the LAN failover set device did work OK until my reconfiguration attempt with that machine.

sorry, i did a silly mistake :

i could not access the original HW to reproduce the trouble, and i tried with an old HW with network controlers which do NOT support the LAN failover set device !

Very useful thread, it showed me that the TCPIP name of the logical LAN device LLA0 (LAN failover under OpenVMS MC LANCP) is NOT LL0 (what i would have guessed) but LE0.

Where else could i have leant this ??
